[FFmpeg-devel] Awakening of FFH264

[Kvikant, Christian]

A bit later than anticipated but here is a patch against r22635 that 
reintroduces FFH264 into FFmpeg.

Some of the work include:
-    Original code has been ported against trunk
-    Corrected macro block generation
-    Moved some functions to a H264DSPEncContext for future porting to 
arm/neon
-    Added generation of VUI / SAR information to SPS
-    Added access unit delimiters, available through CODEC_FLAG2_AUD


To include the encoder use:

  ./configure --enable-encoder=h264

To test out the encoder try:

  ./ffmpeg -i ./input.avi -an -vcodec ffh264 ?s 320x240 ?qscale 25 
./output.avi

The encoder has been successfully compiled and used with Fedora, 
Win32/Mingw and OS X Snow Leopard. It has also been tested with 
gst-ffmpeg. The generated output has been tested to work with VLC, 
QuickTime 7, JM Reference Software and iPhone?s media player.

TODO:
-    File names should be reconsidered
-    Code review
-    Add regression tests

Mvh,
Christian
