855ea723b0 * two functions to handle allocation of static data more simple 
av_mallocz_static - called for every static data table
  av_free_static - called when ffmpeg is no longer needed and should free
                   all static resources
* simple usage shown in mpegaudiodec.c

c11ef252e6 Fixed problem with frame rate reduction when capturing from a source 
whose PTS does not start at zero. New code will fix that if the PTS
is more than 100 seconds from zero. This may well not be the right
number, but it is a big improvement over the current state.

10d104e4f6 * Add frame rate conversion when there is no audio channel. This makes 
ffmpeg/ffserver work again when just capturing video from a live
  source and you are streaming feeds of different frame rates.
* Fix a segfault in argument processing
* Add handling for -vhook argument
* Add logic to call video hooks if any have been specified.

cb09b2ed92 * Go faster stripes: don't check to see if the user presses 'q' if stdin 
returns EOF -- e.g. it is connected to /dev/null
* Make the 1MB video buffer only allocated once rather than on each frame.
  The allocation and deallocation causes significant performance loss as the
  kernel remaps the address space each time.

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.

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.
