Jason Garrett-Glaser	c11cb37520	Check transform==15 first, since it's more common than 13. Patch by Dark Shikari Originally committed as revision 20749 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	306a61b33e	Revert r20747: It mixed functional and cosmetical changes. Originally committed as revision 20748 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	63c0b3d920	Various VP3 optimizations. Faster checks in reverse_dc_prediction. Simplified deblocking checks. Check transform==15 first, since it's more common than 13. Originally committed as revision 20747 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	9d8bb0318a	Small refactoring: Instead of 4 loops for decoding AC coefficients based on their grouping, create one loop that indexes into a table of AC VLC tables. There is also a small optimization here: Do not call unpack_vlcs() if there are no fragments in the list with outstanding coefficients. My profiling indicates that this can save upwards of 1 million dezicycles per frame throughout the course of unpack_dct_coeffs(). Originally committed as revision 20699 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	098523eb28	Use a list to track which fragments coded in this frame still have outstanding coefficients yet to be decoded from the bitstream. Once a fragment reaches end-of-block, remove it from this new list. This change makes the VP3/Theora entropy decode process dramatically faster due to not having to iterate incessantly over fragments which have already been fully decoded.

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	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.
