hmm. the mpeg-es demuxer actually does it... it jjust reads 2048 byte
packets from file and put them unchanegd to the demuxer buffer.

problems
- it puts data to the video queue, not audio
- how to recognize fourcc? maybe -audioformat could do that.. or some hackto
allow selection of any -vc with that demuxer
- many audio codec expects some audio headers in sh_audio_t, to get
channels, samplerate, bitrate. afaik, only ac3 and mp3 can read these from
the raw audio steram, all others use the header from demuxer
