Juanjo e0a3d744a0 - repeat_pict meaning changed, now it signals the extra delay for the
decoded frame.
- extra_delay = (repeat_pict / 2) * (1/fps)

Juanjo 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.
