Michael Niedermayer	bfb39023b0	h264: ff_init_cabac_states doesnt use its argument thus remove it Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	dc7aecd8f7	cabac: use av_assert Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Roland Scheidegger	7f668cd2b5	h264: use one table instead of several for cabac functions 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.

Roland Scheidegger	e52b96187b	h264: (trivial) make ff_h264_lps_state static not used outside the cabac test functions (which probably means it's a bad test if it doesn't use the same tables as the real functions?) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	c834c7e39c	1000l commit forgotten cabac fix Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	55b9ef18e4	cabac: split cabac.h into declarations and function definitions 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.	13 years ago
Diego Biurrun	0a60780c7f	cabac: Mark ff_h264_mps_state array as static, it is only used within cabac.c.	13 years ago
Diego Biurrun	64d779f2f7	cabac: Remove ff_h264_lps_state array. It was only ever used in the cabac test program, but never initialized.	13 years ago
Diego Biurrun	1ef8ff4534	cabac: remove put_cabac_u/ueg from cabac-test. 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.	13 years ago
Diego Biurrun	badb195d13	cabac: Move code only used within the CABAC test program into the test program.	13 years ago
Diego Biurrun	9dec55748c	cabac: drop unused and disabled get_cabac_u() / get_cabac_ueg() functions	13 years ago
Diego Biurrun	e451c26c5f	cabac: drop unused STRICT_LIMITS code branch	13 years ago
Michael Niedermayer	1eb805ed70	cabac test: Change input to test, so a wider range of states is tested. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	830d7d5c4f	cabac test: match encode and decode side Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Michael Niedermayer	f24a515931	shift CABACContext.range right, this reduces the number of shifts needed in 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	18 years ago

Michael Niedermayer	0fa352c7e6	make lps_range a global table its constant anyway (saves 1 addition for accessing it) Originally committed as revision 6653 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	260ceb6322	branchless renormalization (1% faster get_cabac) old branchless renormalization wasnt faster because gcc was scared of the shift variable (missusing bit variable now) Originally committed as revision 6587 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
