- Fixed AC3 decoding for 5:1 AC3 streams. Now when calling av_audio_decode for
AC3 set avcodec_context->channels to the desired number channels, if the
setting is 0 AC3 decoder will set it to the channels found in the
stream.
- Changed ffmpeg to cope with the new "way" of AC3 decoding....

- Commented out PIX_FMT_ANY by now. It seems that not all codecs are setting
the PIX_FMT_ so they get PIX_FMT_ANY instead of PIX_FMT_YUV420P which
obviuosly annoys ffmpeg.

- Added force_pts to av_write_packet() to be able to force PTS, this helps
(and fix) stream copying. By now force_pts it's just honoured by the MPEG
muxer. ASF could honour this also, but it should be fixed to use Tickers
first.
- MPEG audio decoder exports it's frame size in bytes....
