2014-01-15cabac: remove leftovers from the cabac encoderJanne Grunau
The cabac encoder was only used by the removed cabac test. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
2013-09-24h264: do not reinitialize the global cabac tables at each slice headerAnton Khirnov
2013-09-24cabac: remove write-only h264_mps_state[]Anton Khirnov
2013-03-13cabac: remove unused argument of ff_init_cabac_states()Michael Niedermayer
Signed-off-by: Anton Khirnov <anton@khirnov.net>
2012-11-14Drop broken and unused CABAC test program.Diego Biurrun
2012-04-28h264: use one table instead of several for cabac functionsRoland Scheidegger
The reason is this is easier for PIC code (in particular on darwin...). Keep the old names as pointers (static in cabac_functions.h so gcc knows these are just immediate offsets) so the c code can nicely stay the same (alternatively could use offsets directly in the functions needing the tables). This should produce the same code as before with non-pic and better code (confirmed) with pic. The assembly uses the new table but still won't work for PIC case. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
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
2012-01-04cabac: drop unused and disabled get_cabac_u() / get_cabac_ueg() functionsDiego Biurrun

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