Audio stream selection?

[sumawo13]

Does Avisynth have a feature to set the desired audio stream? If not, will it ever have this feature? It would be easier then having to demux audio streams and then using audiodub.

For FFAudioSource() use atrack=X.

For DirectShowSource() you need to manually build an appropriate .GRF file. Apparently there are DirectShow modules that can influence the default graph to select audio tracks. I have not tried them.

For AviSource() currently no.

Track selection is on the to do list, but is a fair way down.

Thanks, it would be nice to have an option in directshowsource() to select audio tracks and even video tracks for MKVs, VOBs, etc.

I'm afraid it's not technically possible because the audio selection is up to the splitter you use. You should have a look at FFmpegSource (http://forum.doom9.org/showthread.php?t=127037).
