2009-09-24Make sure that all memory allocations succeed.Mike Melanson
Based on 28_theora_malloc_checks.patch from the Google Chrome team. Originally committed as revision 20008 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-23Fix >= vs > check of coded_fragment_list_index.Google Chrome
22_fix_theora_frag_fencepost.patch by chrome Originally committed as revision 19995 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-23Fix init_get_bits() buffer size.Google Chrome
18_fix_theora_header_bit_len.patch by chrome Originally committed as revision 19993 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-23Another micro-optimization for unpack_vlcs(): Eliminate a possibleMike Melanson
branch and save around 45k-55k dezicycles per function run. Originally committed as revision 19974 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-22Perform the DC prediction reversal immediately after decoding all ofMike Melanson
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
2009-09-21Modify unpack_vlcs() so that there are fewer dereferences through theMike Melanson
main (heavily iterated) loop. Originally committed as revision 19934 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-06compatible_frame array can be static const, too.Reimar Döffinger
Originally committed as revision 19779 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-05Make vp3 arrays static const where possible.Reimar Döffinger
Originally committed as revision 19771 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-23Remove useless #include <unistd.h> from many filesMåns Rullgård

2009-07-06100l, theora_decode_init must pass on errors from vp3_decode_initReimar Döffinger
Originally committed as revision 19356 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-06Make decode_init fail if the huffman tables are invalid and thus init_vlc fails.Reimar Döffinger
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
2009-07-05Ensure that the filter limit values do not exceed the maximum allowed value ↵Reimar Döffinger
of 127. Originally committed as revision 19351 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-05Extend init_loop_filter to work for filter limit values up to 127 insteadReimar Döffinger
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

2009-04-13Rename bitstream.h to get_bits.h.Stefano Sabatini
Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
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.
