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.

c04643a2c2 * Make video grabbing work again (if you are grabbing multiple streams 
at different frame rates).
* Do the av_abort() change that is not otherwise worth checking in.

6dc96cb0bf - Now ffmpeg handles MPEG-2 streams with pull down, it gets the real frame 
rate of the stream.

51bd4565f7 * Fix nasty problem with unitialized memory in the file_table 
* Add default entries to switch statements to catch programming errors
* Fix problem with high CPU usage when capturing live (the audio grabber
  is non-blocking for some reason). This is the stream_no_data stuff.
* Handle the video grabber getting behind in its work -- PKT_FLAG_DROPPED_FRAME

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.

43f1708f8b - Added PSNR feature to libavcodec and ffmpeg. By now just Y PSNR until I'm 
sure it works ok. Also it's slow, so use it only when you _really_ need to
measure quality.
- Fix libavcodec Makefile to enable profiling.
