WMV with multiple audio tracks

[rhld50]

Hi,

i´m looking for a solution to encode wmv with two audio tracks. What i can do is using the windows media stream editor to add the second audio track later. I need to use a command line tool.
Is there no option to do this with expression encoder or wmcmd?

Thanks a lot

Microsoft's ASF container does not support multiple audio or video audiences. So, what you are attempting to do is not possible. You will need to have two files, each with a different audio stream.

No, not true.
You can mux multiple WMA into WMV with WMstreameditor.

Its a Part of WMencoder 9 Package :)

But : The WMA must have same Bitrate/khz/ etc etc

Really? I tried to add multiple audio audiences into an ASF container with WM9 Stream Editor, and was unable to get WMP11 to play the second audio stream. Plus, most of my WMV is being streamed to the Xbox 360, which does not support playback of an alternate audio stream.

It works without problems for me. You can add a second audio track (which has to be encoded exactly the same way but has another language). In wmp i´m able to select the language i want. haven´t test it on my x360 yet. You can also build your own stream editor based on wme9 sdk (tip from zambelli).

Any idea why the must have the same properties? From what I know of the ASF format there is not really any reason for that (and I would assume that e.g. ffmpeg will happily create files with different audio stream properties).

There is no need to have the same propety for second audio to be muxed in ASF.

Reimar, if you are familar with DirectShow you can use SolveigMM ASF Multiplexer (http://solveigmm.com/?Products&id=ASFMuxer) to mux two or more audio streams with video.

Here is a post you can get some info how to use it.
