Mike Melanson	0efbd068e7	Make sure that all memory allocations succeed. Based on 28_theora_malloc_checks.patch from the Google Chrome team. Originally committed as revision 20008 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Google Chrome	310afddfe0	Fix >= vs > check of coded_fragment_list_index. 22_fix_theora_frag_fencepost.patch by chrome Originally committed as revision 19995 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Google Chrome	fa6f27517b	Fix init_get_bits() buffer size. 18_fix_theora_header_bit_len.patch by chrome Originally committed as revision 19993 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	428984b041	Another micro-optimization for unpack_vlcs(): Eliminate a possible branch and save around 45k-55k dezicycles per function run. Originally committed as revision 19974 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	138fe83215	Perform the DC prediction reversal immediately after decoding all of the DC coefficients. This has a greater probability of leveraging the coefficients while they are still cached. When testing with the Big Buck Bunny 1080p video, I consistently saw improvements of 500k-600k dezicycles per run (through reverse_dc_prediction()) thanks to this move. Originally committed as revision 19966 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	ee3d7f5852	Modify unpack_vlcs() so that there are fewer dereferences through the main (heavily iterated) loop. Originally committed as revision 19934 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	b8791583e7	compatible_frame array can be static const, too. Originally committed as revision 19779 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	bb99108775	Make vp3 arrays static const where possible. Originally committed as revision 19771 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	3aab27b459	Remove useless #include <unistd.h> from many files Originally committed as revision 19499 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	c79c960ade	Remove useless ret variable added in last revision again. Originally committed as revision 19357 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	7cda815044	100l, theora_decode_init must pass on errors from vp3_decode_init Originally committed as revision 19356 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	c4b7b8bf9c	Make decode_init fail if the huffman tables are invalid and thus init_vlc fails. Otherwise this will crash during decoding because the vlc tables are NULL. Partially fixes ogv/smclock.ogv.1.101.ogv from issue 1240. Originally committed as revision 19355 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	e13cca4b14	Ensure that the filter limit values do not exceed the maximum allowed value of 127. Originally committed as revision 19351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	7fa5f9990b	Extend init_loop_filter to work for filter limit values up to 127 instead of only up to 64. 127 is the maximum value allowed by the theora specification. Originally committed as revision 19350 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
