Windows Media Stereo Muxer v.1.0

We use the Windows Media Stereo Muxer command line tool to multiplex left and right file. Open a command line window (Start->Run, enter Cmd) and type WmxMux.exe -i1 "Oldtimers 1080p Left.wmv" -i2 "Oldtimers 1080p Right.wmv" -o "Output.wmv" (adjust the filenames). If WmvMux.exe and your video files are not located in the same directory, it is necessary to specify paths, e.g. "C:Left.wmv". Input one (-i1) must be the left file, input two (-i2) the right file. Run WmvMux.exe without parameters to get a list of all available options.Stereoscopic Player displays a preview image for each video in the built-in video library. The preview image can be embedded in the Windows Media file, so that no additional metadata file is required. The following restrictions apply for preview images: * JPEG format * 160 x 120 pixels resolution * Maximum size of 10 kB (10240 Bytes)To embed the preview image, use the -p parameter, for example -p "Oldtimers.jpg".By default, the output file will contain the audio track of the first (left) input file only. To keep all audio tracks, specify the -a parameter. Use this option only if your left input file doesn't contain an audio track but only the right one. Avoid to multiplex two audio tracks into the output file (except multi language audio tracks, see below)!If you have forgotten to choose the proper language in Windows Media Encoder, the Windows Media Stereo Muxer allows to fix it. Specify -l1 "en-us" and -l2 "en-us" to set the language of all streams to English. A list of valid language codes is available here. The complete command will look like this:Windows Media Stereo Muxer command lineWindows Media Stereo Muxer will display an error message if the input files differ in length. If you edited and encoded left and right files properly, this should never happen. Nevertheless, parameter -x allows to ignore different lengths and -d limits the duration of the output file. For example -x -t 6000 will copy the first minute of input files differing in length to the output file. Use these options only if you know exactly what you are doing!To check and understand the final output file, open it in the Windows Media ASF View (available from Microsoft). Make sure there are three streams (three Stream Properties Objects), two video streams and one audio stream. There should also be an Advanced Mutual Exclusion Object including the video streams. It prevents 2D players from showing both video streams.Windows Media ASF ViewAdvanced Features * Multi stream files: Specify additional input files -i3 , -i4 and so on. Input files must be ordered from left to right, -i1 is the most-left view. * Multi language audio tracks: Inputs -i1 and -i2 should contain video streams only. To remove audio streams from existing Windows Media files, use the Windows Media Stream Editor, which is shipped together with Windows Media Encoder. Encode each audio track separately. The same profile must be used to encode the audio tracks! The Windows Media Stereo Muxer's command line will be like this: WmvMux.exe -i1 "Left.wmv" -l1 "en-us" -i2 "Right.wmv" -l2 "en-us" -i3 "English.wma" -l3 "en-us" -i4 "German.wma" -l4 "de-de" -p "Preview.jpg" -a * 2D Intro: It is possible to define an intro at the beginning of the file which will be played back by 2D video players only, but skipped by Stereoscopic Player. The intro can be used to display a message like 'This is a stereoscopic video file. Use Stereoscopic Player to play it in 3D.' The intro must be present in the original left and right files. The -t parameter is used to define the intro duration. For example, -t 500 sets the intro duration to 5 second.

You can obtain it from Microsoft. Dual stream files are encrypted the same way as ordinary video files. Please consult the Windows Media Rights Manager SDK for more details. Do not use player individualization because this mechanism is not supported by Stereoscopic Player yet. Don't use advanced security levels either.In the previous chapter, we created a left and right Windows Media files. Using Stereoscopic Player's File->Open Left and Right File feature, it would be possible to play them in 3D. However, we would like to merge them to a single file, because only the single file/dual stream format offers best usability.
