e0d2714adc - 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.
- ASF muxer now uses Tickers for PTS calculations.

9f862d1133 - PIX_FMT_ANY = -1 to avoid breaking any stuff that could be using it.

dbc598bb79 - 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.

10bb7023a2 - 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.
- Hope this fix the floating point exception found in ffserver.
