video/audio output to NULL (reposted)
 

It would be nice if there were options to disable the decoding of one stream or another (video or audio, especially video)
I don't know how usefull it would be for normal users, but it would be useful for debugging
What I'm interested in (especially) is to listen the soundtracks of certain video files (e.g. certain documentaries have beautiful ambiental music) without loading the CPU with the processing of the video stream (it's useless if I'm not watching it, but only listen it)
