* Cosmetic: indent after last change.Mike Melanson2009-12-19
| | | | Originally committed as revision 20896 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Optimize unpack_vectors() by not shuffling around redundant vectors.Mike Melanson2009-12-19
| | | | | | | | Inspired by guidance from Dark Shikari. On a Core 2 Duo 2.0 GHz, this change decodes the 10-minute Big Buck Bunny 1080p short about 2 seconds faster. Originally committed as revision 20895 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Various VP3 optimizations.Jason Garrett-Glaser2009-12-06
| | | | | | | | 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
* Small refactoring: Instead of 4 loops for decoding AC coefficients basedMike Melanson2009-12-02
| | | | | | | | | | | | 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
* Use a list to track which fragments coded in this frame still haveMike Melanson2009-12-02
| | | | | | | | | | 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. Originally committed as revision 20698 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Make sure that all memory allocations succeed.Mike Melanson2009-09-24

* Another micro-optimization for unpack_vlcs(): Eliminate a possibleMike Melanson2009-09-23
| | | | | | branch and save around 45k-55k dezicycles per function run. Originally committed as revision 19974 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Perform the DC prediction reversal immediately after decoding all ofMike Melanson2009-09-22
| | | | | | | | | | | 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.

* Make decode_init fail if the huffman tables are invalid and thus init_vlc fails.Reimar Döffinger2009-07-06
| | | | | | | 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

| | | | | | | | | | | 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.
