Run TVE SDK in 64 bit Windows

Blue Pacific Support — Mon, 07 Sep 2009 22:23:00 GMT

Abstract:

Introduction
	Starting from build 4.1.217.0 TVE SDK includes a native 64 bit .NET component which can be used in any flavor of 64 bit Windows. However there are some limitations listed in this article.

Information
	64 bit version of TVE SDK is still in beta period. We are still testing it and we welcome any feedback you may have. There are some limitations regarding the 64 bit version of TVE SDK: It is still in beta - you may find some bugs which we will be glad to know about. The Quicktime framework is not included because Apple does not yet provide a 64 bit version for Quicktime SDK. It doesn't mean TVE SDK doesn't support all Quicktime formats - it does still support several Quicktime formats depending on the third party codecs you may install (see below). There are less codecs available for 64 bit systems - meaning TVE SDK may not be able to use as many input video formats as the 32 bit version. Even so, the 64 bit codecs available is growing by the day and soon this will not be a problem any more. See related articles below to learn how to install 64 bit codecs. Install the 64 bit version of TVE SDK First, proceed exactly as installing the 32 bit version. The 64 version dll of TVE SDK's .NET component is located inside the x64 directory. To install TVE SDK into your .NET website just copy the Turbine.TVE4.dll file and lame_enc_x64.dll to your Bin directory in your website.

Introduction
	You can use TVE SDK in a 64 bit Windows system. This article shows two valid options to accomplish this task.

Solution
	The first option is to use the native 64 bit .NET component of TVE SDK as described in a different KB article listed in Related Articles section below. The second option is to use the 32 bit version of TVE SDK but configure IIS to switch to 32 bit mode: When trying to run the TVE SDK sample web service you get the error "An attempt was made to load a program with an incorrect format." To solve this problem you must switch IIS to 32 bit mode as described in this Microsoft KB article: http://support.microsoft.com/kb/894435 You should now be able to run TVE SDK in any 64 bit Windows system.

Encode Any Video Type to Flash - 64 bit

Blue Pacific Support — Mon, 07 Sep 2009 22:21:00 GMT

Abstract:

Introduction

In 64 bit Windows systems and using TVE SDK 64 bit version, what extra software components should be installed in order to get the maximum video formats to encode to Flash (H.264, FLV or SWF)?

Solution

TVE SDK uses several video frameworks as well third party codecs to be able to read a great deal of video formats. This feature makes the software able to deal with almost any video type and format.

We recommend the following software:

To convert Windows Media (AVI, WMV, ASF, WMA, WAV, using any AVI/WM codecs like DIVX, XDIV, etc), install the latest version of Microsoft Windows Media Player:
http://www.microsoft.com/windows/windowsmedia/

There are many codecs and video formats. For maximum compatibility with these formats and to warrant TVE SDK is able to decode them, we recommend K-Lite Codec Pack 64-bit - a codec pack freely available at:

Unable to Encode Certain Video Type

Blue Pacific Support — Thu, 26 Mar 2009 03:42:00 GMT

Abstract:

Symptoms

When trying to open a video by using any video product (TVE SDK, Web Video Machine, TVE or TVU), it refuses to open by giving an error message or it encodes the video but the encoding is not successful.

Cause

This happens because there might be missing a codec, or the codec is installed but it is missconfigured.

Solution

Codecs can be a problem as different systems have different codecs installed with different versions and therefore it is almost impossible to provide a sound solution.

However, most videos can encoded by installing the missing codec. Start by installing the recommended software listed in this KB article:
http://www.blue-pacific.com/support/kb/article.aspx?id=10413

Next, follow these simple steps to enable the proper codec:

Open the problematic video with GSpot - a free software tool which can be downloaded from http://www.headbands.com/gspot/.
GSpot will find what type of video and audio codec the problematic video is using.
Open "ffdshow video decoder configuration" - a configuration panel installed with Combined Community Codec Pack. Select "Codecs" and a list of all available codecs will show.

Locate the codec previously discovered

Video Codecs Used by TVE SDK

Blue Pacific Support — Thu, 12 Mar 2009 22:55:00 GMT

Abstract:

Introduction
	What codecs are used by TVE SDK to generate video?

Information
	Starting in version 4, TVE SDK outputs H.264 - the new high quality video format implemented in the latest update to Adobe Flash Player. TVE SDK also outputs FLV version 6/7 which is based on high quality open industry standards (h.263/h.263+). Starting in version 3, TVE SDK can also use a new lossless video codec to generate FLV. TVE SDK generates the exact same video format YouTube and Google Video use. Turbine Video Encoder, Turbine Video Uploader and Web Video Machine, all use TVE SDK as its encoding engine, and therefore, this information also applies to it.

What are the Main Differences Between Web Video Machine and the Video Engine SDK?

Blue Pacific Support — Tue, 30 Dec 2008 01:36:00 GMT

Abstract:

Introduction
	Both products Web Video Machine (WVM) and Turbine Video Engine SDK (TVE SDK) encode video to Flash. However there are some significative differences between the two products.

Information
	TVE SDK is a SDK containing several programming components intended to be used by programmers developing a web site or desktop application for encoding video to Flash. Because of its versatility, the SDK can be used to develop any video application. A typical set of tasks to implement an online video conversion application: The developer learns the simple SDK API. He or she integrates the SDK with the online application in order to extend its functionality to convert video to Flash. On the other hand, WVM is a finished application that enables website users to convert video to Flash as soon as it is installed. WVM does not require any kind of programming skills to use it: After installed in a website, WVM is ready to start the encoding process. Website owner may adjust settings by using the WVM Dashboard.

Abstract:

Introduction
	Both products Turbine Video Uploader (TVU) and Turbine Video Engine SDK (TVE SDK) encode video to Flash FLV. However there are some significative differences between the two products.

Information
	TVE SDK is a SDK containing several programming components intended to be used by programmers developing a web site or desktop application for encoding video to Flash. Typically, the SDK when used in a web site, converts the video on server side: User uploads any video format to website. TVE SDK installed in the website performs video conversion to Flash video. On the other hand, TVU is a finished desktop application that enables website users to convert their video to Flash, but this conversion takes place on the user’s computer. After it is converted, it may uploaded to the website: User downloads TVU from site and installs it into his PC. User drags and drops a video to TVU. TVU converts the video to Flash video and uploads the result to website.

Use FLV Video as Input

Blue Pacific Support — Mon, 17 Nov 2008 22:30:00 GMT

Abstract:

Introduction
	Do TVE and TVE SDK support FLV video files as input? The answer is yes, if you install the right software.

Solution
	To be able to use FLV files as input video, and therefore re-encode it to FLV, you must install the right codecs. Start by installing the software recommended in this KB article: http://www.blue-pacific.com/support/kb/article.aspx?id=10413&cNode=3Q1G2S After installing, open the ffdshow "video decoder configuration". Enable "H.263", "FLV1", "VP6" and "VP6F" under "Codecs" - set these options to "libavcodec". Warning: we've recently discovered that these codecs may not work in a webserver context when used with TVE SDK, therefore, if you need to encode FLV in a webserver, we recommend a queuing system where videos are encoded one at a time. To see how to do this, please refer to the samples included: examples\WindowsService examples\VBScript\batch.vbs

Deploy TVE SDK for .NET 2.0

Blue Pacific Support — Wed, 08 Oct 2008 23:57:00 GMT

Abstract:

Introduction
	Learn how to deploy TVE SDK for .NET 2.0 to your website.

Information
	Deploying TVE SDK to a .NET website is as simple as following these simple steps: Locate the Turbine.TVE4.dll file located in your TVE SDK root installation directory. Copy this file to your website bin directory. Usually this directory already exists and is located at the root of your website. If you can't locate it then you can create it, or ask your hosting provider where it is. If you wish to use MP3 audio, then you must also upload lame_enc.dll to the same bin directory. Test your site, and if you still get an error message, then you probably need to install VC++ 2005 SP1 Redistributable Package. Consult the Microsoft website for further information about installing a .NET component by using the XCopy method.

Supported Video Files

Blue Pacific Support — Tue, 30 Sep 2008 21:02:00 GMT

Abstract:

Introduction
	What kind of video files does TVE, TVU and TVE SDK support? Although the software supports many input video formats, you may encounter some problems when trying to encode some kind of video files.

Information
	As a rule of thumb, if one can play a video by using either Windows Media Player or QuickTime Player, then TVE, TVU and the SDK can also handle it. If it doesn't play, you may be missing a codec. You can check which codec is missing by using AVIcodec a freeware software available here: http://avicodec.duby.info/ TVE, TVU and The SDK can also handle AVI formats with user installed codecs. The most common video formats supported are: Windows Media (AVI, WMV, ASF, WMA, WAV, using any AVI/WM codecs like DIVX, XDIV, etc.); QuickTime (MOV, QT, DV, AAC, AIF/AIFF, using any QuickTime codecs); MPEG (MPEG-1, MPEG-2, MPEG-4, MP3); Mobile Phones (3GP, 3G2); Real Media (RM, RMVB); Flash (FLV); Images (PNG, JPG, BMP, animated GIF). To learn how to maximize the number of video types TVE, TVU and the SDK can handle, please refer to the KB article linked in the "Related Articles" section below.

Create Video with a Sequence of Images

Blue Pacific Support — Thu, 25 Sep 2008 21:06:00 GMT

Abstract:

Introduction

Sometimes it is useful to transform a sequence of images and an audio track to a single video, and at the same time, be able to synchronize the image sequence with audio.

This feature is most useful for presentations and tutorials.

Solution

Two new methods were introduced that make this feature possible:

EncodeSequenceAudio
EncodeSequenceFrame

A code example that accomplishes this task is:

' create the TVE object:
Set tve=Server.CreateObject("TVE4COM.TVE")

' load preset settings:
tve.LoadSettings "default.settings"

' set the filename of the output:
tve.SetOutputFile "presentation.flv"

' select the audio track:
tve.EncodeSequenceAudio "audio_track.wav"

' select the image frames:
' frame will be shown at instant 0.5 seconds from the beginning
tve.EncodeSequenceFrame 500*1000, "frame01.png"
' frame will be shown at instant 1 second from last frame
tve.EncodeSequenceFrame 1000*1000, "frame02.png"
' frame will be shown at instant 2

Evaluation Watermark Appears on Registered Version

Blue Pacific Support — Wed, 30 Jul 2008 05:16:00 GMT

Abstract:

Symptoms
	After installing the registered version of Turbine Video Engine SDK (TVE SDK), the evaluation watermark still appears.

Solution
	Please review the following items, whose absence can be causing the problem: Make sure you installed the Registered setup and not the Evaluation setup. The filename for the Registered setup version will include the word 'Registered'. Check whether the TVE SDK DLL file is the registered version: in Windows Explorer right-click on the Turbine.TVE4.dll or TVE4COM.dll file, then select Properties, then select the Version Tab - the word Registered should appear on the Description field. Do a system wide search for these DLLs if in doubt. Make sure to fully restart the web server. When using Microsoft IIS, this might require a restart of the W3SVC service or a machine reboot. After these steps are correctly reviewed/performed, TVE SDK should be running in its full registered version.

Playing Videos from a Different Path

Blue Pacific Support — Tue, 17 Jun 2008 04:49:00 GMT

Abstract:

Introduction

Turbine Video Encoder saves the encoded videos as several files: .html, .swf, .flv and .jpg files, which are saved in the same folder. It is sometimes useful to have the .swf and .flv files in a different folder - for example into a separate media/ folder, different than the folder where the .html file will be located.
This article applies in a similar way to playing video files generated by Turbine Video Engine SDK.

Solution

For this to happen we must change a few attributes inside the <Object> and <Embed> tags that display the video in the .html file. This also applies to any other HTML file, for example dynamic HTML generated from ASP or PHP.

To do this we'll need to edit the HTML file as in the following steps, which assume the video is called video.swf (that is: originally saved as video.flv, video.html, etc.) and will be located in a folder named media:

Move all files, except the .html file into the new location inside the media/ folder.
Edit the .html file: inside the <Object> tag which displays the Flash player, locate the movie attribute of the <param> tag:
<param name="movie" value="video.swf">
And change it to the new path:
<param name="movie" value="media/video.swf">
After this tag, add a base <param> attribute which sets the base directory for the loaded media - take care to leave the final slash as in "media/":
<param name="base" value="media/">

Now we'll do the

Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Cause
	Your system lacks a required Microsoft dll. After installing this dll the problem should be solved.

Solution
	TVE SDK requires VC++ 2005 SP1 Redistributable Package which can be freely downloaded from Microsoft website: http://www.microsoft.com/downloads/details.aspx?FamilyID=200B2FD9-AE1A-4A14-984D-389C36F85647 After installing it, TVE SDK should now run without any kind of problem.

Pentium 4 Speed Optimization

Blue Pacific Support — Fri, 04 Apr 2008 01:21:00 GMT

Abstract:

Introduction
	Speed is a major concern when dealing with video which files are typically large and therefore the encoding process is very CPU intensive.

Information
	TVE, TVU and TVE SDK are optimized for Pentium 4 SSE2 so when running in a Pentium 4 machine it takes advantage of this optimization boosting the encoding speeds to nearly twice as fast than in other processors. Thread encoding priority can be changed in TVE SDK by using the EncodeAsyncPriority property.

Better Quality Encoding

Blue Pacific Support — Fri, 04 Apr 2008 01:12:00 GMT

Abstract:

Introduction

Video encoding quality depends on the encoding bitrate as well as the characteristics of the source video: videos with a lot of action will always be harder to compress than still videos (at the same bitrate). However it's often possible to increase quality by changing some settings from the default values included in the base Presets.

Information

Better quality encoding can be obtained by changing a number of settings:

Increasing bitrate in video (the VideoBitRate property) and audio (Audio MP3BitRate or AudioADPCMBits properties) naturally increases quality. Or lower the video frame size (VideoWidth/Height property) and/or the frame rate (VideoFrameRate property): this will lower the amount of actual data compressed, allowing better quality for the same bitrate. In most cases source video quality might be overkill for web Flash video: for example lowering the frame rate from 30 FPS to 20 or the frame image to 75% original size will produce better video quality at the same bitrate without significant quality loss.
Using VBR2 encoding will usually produce better results (VideoMethod property). Or if bandwidth is not an issue, encoding at Constant Quality (KQ) with better quantizer settings will produce perfect results.

The period for intra frames (complete frames) might be too small, wasting bandwidth. This can be changed in the VideoIntraFramePeriod

Error Message in Player: "Media stream not found"

Blue Pacific Support — Wed, 16 May 2007 05:00:00 GMT

Abstract:

Introduction
	After uploading the encoded files into a web server, requesting the video causes the message "Media stream not found" to appear in the player.

Solution
	This error may happen due to: Check that the .flv is in the server and has the same size as the local encoded file. There could be an issue in the web server with the FLV mime-type.

Include Playback Controls

Blue Pacific Support — Wed, 16 May 2007 04:29:00 GMT

Abstract:

Note: this article does NOT apply to TVE SDK Version 2 or TVE Version 2. It applies to version 1 only.

Introduction
	Videos encoded in Turbine Video Encoder can include playback controls such as play, stop, pause, etc. This article shows how playback controls can be be added to encoded videos.

Solution
	Use Preloader/Overlay files, in particular the 'Controls' files. To accomplish this: 1. Select the 'Flash' tab 2. In the 'Preloader/Overlay' field, select one of the files that have 'Controls' in their filename, for example: 'Overlay - Mach 2 Controls.swf'. After this operation, click on the 'Encode' button and the produced Flash movie will contain the selected controls. On TVE SDK, the same overlays can be used with the same results.

Stop the Video at the Beginning

Blue Pacific Support — Wed, 16 May 2007 04:28:00 GMT

Abstract:

Note: this article does NOT apply to TVE SDK Version 2 or TVE Version 2. It applies to version 1 only.

Introduction
	Video encoded in Turbine Video Encoder and TVE SDK starts automatically by default. Sometimes the desired behavior would be that the video starts in stopped state, for example to be started from external scripting. This article shows how to accomplish this behavior with Turbine Video Encoder 1.0 (on TVE SDK, the same overlay should be used).

Solution
	Load the 'Overlay - Stop at the beginning.swf' overlay. To accomplish it: Select the 'Flash' tab In the 'Preloader/Overlay' field, select the 'Overlay - Stop at the beginning.swf' overlay. After this operation, click on the 'Encode' button and the produced Flash movie will stop at the beginning.

Flash Movie Size Limits

Blue Pacific Support — Wed, 16 May 2007 04:27:00 GMT

Abstract:

Note: this article does NOT apply to TVE SDK Version 2 or TVE Version 2. It applies to version 1 only.

Introduction

This article provides information about the size limits associated with the Flash format and refers how some of these limitations can be worked around with Turbine Video.

Information

Macromedia documents on their Knowledge Base Technote 14437 a frame limit of near 16000 frames for Flash movies. Besides this limit, huge amounts of consumed memory can cause the machine where the movie plays to function slower or even create stability problems, usually on older operating systems with smaller amounts of physical memory.

Turbine Video Encoder features the 'Optimize Player Memory' setting which minimizes the memory consumption problem by forcing the player to perform memory garbage collection. Turbine Video will display an estimate of the amount of memory needed to play the encoded movie - this value is available on the encoded Flash area. It's usually advised to avoid creating movies that consume more than 60 MB of Flash player memory. Due to the inter-frame compression capabilities of Turbine Video, the encoded movies will have a reduced size, specially when using lower Video Quality settings. Turbine also includes the 'Part Split Size' setting that will allow you to encode the entire selecting into a number of linked parts, having, for example each up to 50 MB.

Regarding the 16000 frame limit, Turbine Video Encoder will warn you if the existing encoding selection

Encoded Videos Display Compression Artifacts

Blue Pacific Support — Wed, 16 May 2007 04:26:00 GMT

Abstract:

Note: this article does NOT apply to TVE SDK Version 2 or TVE Version 2. It applies to version 1 only.

Symptoms
	Flash movies encoded with high-compression/low-quality settings display a lot of compression artifacts. How can these compression artifacts be avoided?

Solution
	Using low values for some of the settings can cause compression artifacts to pop into the encoded Flash video. On the Turbine Video Encoder interface, settings that can have this kind of effect are marked with a thin red line below the respective slider. The immediate solution is to increase the encoding settings, notably the Video Quality setting until the artifacts disappear or decrease to an acceptable level - usually this means setting the slider to after the thin red line zone.

Movie doesn't Compress Below a Certain Size and Bitrate

Blue Pacific Support — Wed, 16 May 2007 04:25:00 GMT

Abstract:

Note: this article does NOT apply to TVE SDK Version 2 or TVE Version 2. It applies to version 1 only.

Introduction

After selecting several different encoding qualities, the generated movie still will not encode smaller than a certain size (and bitrate).

Information

Encoding video and audio is always a tradeoff between quality and file size. Turbine Video Encoder includes sophisticated compression methods designed to attain several forms or inter and intra-frame compression. However on some source movies, either because of large image dimensions, high frame rate, or lack of frame redundancy, compression below a certain point is more difficult to achieve. For example, a worst case scenario is trying to encode an untuned television/white noise video, which contains practically no redundancy.

Nevertheless, several things can be tried:

Lower the Frame Rate on the Video Settings area - this will remove a large number of the originally involved image blocks.
Reduce the image Frame Size on the Video Settings area - compensate by adding a little of smoothening.
Increase the smoothening (Video Settings Area) applied to the image, by increasing the Smoothness percentage and the number of Smooth Cycles.
Lower the Video Quality, on the Video Settings Area.
Enable the advanced Compression types, available on the Advanced Settings area, and select the involved quality levels, to be as lower as possible.

Turbine also includes the 'Bit Rate

Known issues with Input Video Formats

Blue Pacific Support — Wed, 16 May 2007 04:18:00 GMT

Abstract:

Introduction
	In general, if Windows Media Player or the QuickTime Player can play a video file, Turbine Video will also be able to encode it. However the interfaces exposed by the Windows Media and QuickTime programming interfaces need to be used by TVE in a more sophisticated way than those players which might cause problems. For example some formats are encoded only for start-to-finish play and do not allow seek operations, which makes it impossible for TVE to advance to the middle of the video.

Information
	The following are the currently known issues with video input formats for Turbine Video Encoder and Turbine Video Engine SDK: Windows Media Format .asf or .wmv video files with non-seekable flag (not indexed) can only encode from the beginning (for any duration up to the end). In Turbine Video Engine this can be checked with InfoGet() flag "videoIsSeekable". QuickTime .mov files in MPEG1 Muxed format cannot have their audio encoded as it's not properly returned by QuickTime interface. These files can be demuxed with a product such as MPEG StreamClip: http://www.squared5.com. Some 3GP files encode and display as white frames if QuickTime version 7 is installed. This is a known problem introduced in the QuickTime 7 framework, the current known workaround is to install QuickTime 6.x, which doesn't exhibit this problem.

Video Encoding Hangs or is Very Slow

Blue Pacific Support — Wed, 16 May 2007 04:16:00 GMT

Abstract:

Symptoms
	If ffdshow is installed, encoding of certain video files might be very slowly or even hang. To learn whether ffdshow is being used during encoding, check the Windows desktop task bar for one or two ffdshow icons (and/or video codecs). If you see one or two such icons, ffdshow is being used.

Solution
	To solve this problem, you can simply uninstall ffdshow or the package that contains it (for example the K-Lite codec pack) in Control Panel Add/Remove Programs. Alternatively, you can disable ffdshow handling the video/audio codecs used on the video you'll be encoding. This can be done by performing these steps separately for ffdshow audio and video icons: Right-click on each of the ffdshow audio and video icons in the task bar - a popup will appear. Check the text in the second option of the popup. Click on the second option of the popup, a ffdshow window will appear. On this window, select "Codecs" on the left side. Now in the right side, locate the codec checked in step 2 and disable it by setting the Decoder option to "disabled". Close the TVE application, launch it again and encode - the ffdshow icons should not appear in the task bar. If you receive an error opening the video this means that the codec is not installed - if you know the codec's name, locate it in a search engine or you can use an application such as "GSpot Codec Information" to learn more about the video file.

Error Encoding DV Format Video File

Blue Pacific Support — Wed, 16 May 2007 04:15:00 GMT

Abstract:

Symptoms
	When encoding a DV format video which was created in Microsoft's Windows Movie Maker, the audio will not encode, even if the video plays in Windows Media Player.

Cause
	This may happen if the source DV camera is set to a sampling rate of 32000 (32KHz) - in this case, Windows Movie Maker will create an incorrect DV format file with headers set to 32000 but actually containing a 48000 audio stream. Due to this, the video is not correctly parsed by some video applications, including Turbine Video Encoder and Turbine Video Engine SDK.

Workaround
	This problem can be solved by using one of the following workarounds: Use an application other than Windows Movie Maker. Record the audio track at a sampling rate of 48000 (48KHz). Correct the video file with VirtualDub: set video processing to "Direct Stream Copy" and set the audio sampling rate to PCM 48KHz (or to any other rate).

Small Memory Leaks in Repeated Encodings

Blue Pacific Support — Thu, 19 Apr 2007 01:50:00 GMT

Abstract:

Symptoms
	When encoding several videos in the same process, either reusing the TVE object or creating and destroying it in a loop, small memory leaks might be observed. These leaks vary depending on the framework used (QuickTime, Windows Media, DirectShow) and are somewhat small: in the order of a few KBytes per a 100 encodings.

Workaround
	Blue Pacific has conducted exhaustive testing and profiling and is quite confident that there are no memory leaks on the TVE SDK code itself. The small memory leaks are apparently happening inside the QuickTime, Windows Media or Direct Show frameworks which TVE uses to read video frames and audio segments. Since these frameworks then use a number of third party codecs it's hard to pin-point the exact location of the problem. A simple solution to workaround this issue is to restart the encoding process after a certain number of encodings. Or if performance allows it, to use a single process for each encoding. Restarting a process will clean whatever memory might have been leaked. Important: In the .NET component, make sure to call the Dispose method for allocated memory to be deleted - this is normal behavior and not related with the small memory leaks mentioned above.

Encoding in Real Time

Blue Pacific Support — Thu, 19 Apr 2007 01:44:00 GMT

Abstract:

Introduction
	Can TVE SDK encode video in real time?

Information
	Video encoding is a very time consuming process, so making it nearly real-time may be difficult and depends largely on the video being encoded and the number of videos being encoded simultaneously (both factors you don’t control). To avoid these problems, usually the video is handled in batch mode, where the user is later notified when his/her job is finished. Look into the samples folder for examples on how to do this.

CPlusPlus Example Errors in Visual Studio 2005

Blue Pacific Support — Thu, 19 Apr 2007 01:41:00 GMT

Abstract:

Symptoms
	When compiling the CPlusPlus example included in TVE SDK, errors such as the following are displayed: Error LNK2019: unresolved external symbol "... wchar_t ..."

Cause
	This error happens due to a change in behavior of Visual Studio 2005 with respect to the wchar_t built-in C++ type.

Solution
	To solve this, simply go to Project/Properties/Configuration Properties/C++/ Language and set "Treat wchar_t as Built-in type" to "No". Current version of TVE SDK already includes a Visual Studio 2005 project with this setting defined.

Extract Several Video Frames

Blue Pacific Support — Thu, 19 Apr 2007 01:36:00 GMT

Abstract:

Introduction
	Frames extracted from a video can be very useful to create a "story-board" of the video. With TVE SDK video frames can be extracted very easily.

Solution
	Since build 2.2.417, launched in the 26th July 2006, TVE SDK contains two new methods that allow extraction of input video frames and processed video frames. Processed video frames are frames with the video settings applied to them (for example resized, with effects, etc). The following two methods allow extraction of video frames to local JPEG files: - InfoSaveInputFrame - InfoSaveProcessedFrame For an example of how these methods work, see the extract-frames.vbs example included with the SDK; or see the Manual entries for these methods.

Encoding from ASP Pages

Blue Pacific Support — Thu, 19 Apr 2007 01:34:00 GMT

Abstract:

Introduction
	This article includes an example on how to encode from an ASP script.

Information
	Encoding from an ASP is very similar to encoding as in the VBScript examples included in the SDK samples. Please take care that encoding multiple videos simultaneously will be very taxing on any machine, no matter how powerful it is. A better solution for sites with heavy concurrent encoding could be offline batch encoding, examples of which are included in the SDK samples. Make sure the directory where the script is located has write permissions for the IIS (Internet Information Server) user, or encoded videos cannot be saved.

New Lossless FLV Video Codec

Blue Pacific Support — Thu, 19 Apr 2007 00:52:00 GMT

Abstract:

Introduction
	Besides the existing FLV codec available in version 2 (lossy), there is a new lossless FLV video codec available in version 3. What is it good for and what are the main differences?

Information
	The new lossless codec is specially designed for applications for which is important to retain all the information without loosing any encoding quality. Applications such as: Screen capture applications - applications for which only small portions of the screen change at a given time. Video dealing with text - for these applications it is very important that text remains readable. Although the lossless codec compresses data, it is unable to use the same compression rate as the lossy FLV codec, which makes the output video usually bigger in size. The lossless codec is fully supported by Adobe Flash Player 7 and later.
