2012-01-13cabac: split cabac.h into declarations and function definitionsDiego Biurrun
This fixes standalone compilation of some decoders with --disable-optimizations. cabac.h defines some inline functions that use symbols from cabac.c. Without optimizations these inline functions are not eliminated and linking fails with references to non-existing symbols. Splitting the inline functions off into their own header and only #including it in the places where the inline functions are used allows #including cabac.h from anywhere without ill effects.
2012-01-13cabac: Mark ff_h264_mps_state array as static, it is only used within cabac.c.Diego Biurrun
2012-01-13cabac: Remove ff_h264_lps_state array.Diego Biurrun
It was only ever used in the cabac test program, but never initialized.
2012-01-09cabac: remove put_cabac_u/ueg from cabac-test.Diego Biurrun
The functions are not used in any part of Libav, therefore testing them in the cabac-test is unnecessary. Since this makes them unused, remove the functions.
2012-01-08cabac: Move code only used within the CABAC test program into the test program.Diego Biurrun

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun

get_cabac() and is slightly faster on P3 (and should be much faster on P4 as the P4 except the more recent variants lacks an integer shifter and so shifts have ~10 times longer latency then simple operations like adds) Originally committed as revision 6702 to svn://svn.ffmpeg.org/ffmpeg/trunk
