Reimar Döffinger	8764389d47	Fix vp3_draw_horiz_band to calculate chroma offsets correctly for 4:2:2 and 4:4:4 formats. Originally committed as revision 23537 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	a4501a45db	vp3: Skip the loop filter when strength is 0 or when requested Originally committed as revision 23346 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	cc46005f50	theora: Don't read an excess bit for maximum length long bit runs if the run exactly ends the remaining blocks. Originally committed as revision 23304 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	8e6daa4a95	theora: coeff huffman codes are allowed to be up to 32 bits long (for 32 tokens) Originally committed as revision 22931 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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

Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	14268254c8	vp3: Split out motion vectors to their own array 1.5% faster overall decode on my penryn Originally committed as revision 22504 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

David Conrad	f50dafa8fc	vp3: avoid buffer overread in coeff decode I couldn't measure it to be slower for normal interframe videos. For the worst case, high-bitrate intra-only videos, it can be 0.7% slower. Originally committed as revision 22416 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	d63a718764	vp3: correctly clip vp3_draw_horiz_band call Originally committed as revision 22377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

David Conrad	e72d2d1221	vp3: Don't leak buffers on errors Originally committed as revision 22358 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	739b5090af	vp3: Simplify buffer management Originally committed as revision 22357 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	01f9640b21	vp3: be less spammy on broken files Originally committed as revision 22356 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	e2720b6b1e	Really fix 2.95 Originally committed as revision 22204 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	0448ef7788	Maybe fix gcc 2.95 Originally committed as revision 22203 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	c72625f299	Delay translating DCT tokens into coefficients until immediately before IDCT This is generally around 12% faster than the prior method of creating a linked list for each block as tokens are read, but can be anywhere from 8% to 28% faster depending on file and CPU. Originally committed as revision 22190 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	7a095ea6fb	Do MC and IDCT in coding (hilbert) order This increases the slice size to 64 pixels, due to having to decode an entire chroma superblock row per slice. This can be up to 6% slower depending on clip and CPU, but is necessary for future optimizations that gain significantly more than was lost. Originally committed as revision 22189 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	35c28d23cb	Explictly separate decoding whether fragments are coded by plane Originally committed as revision 22188 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	770128c448	Remove declaration of unused variables. Originally committed as revision 22102 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	6cb35b45e6	Simplify determing whether fragments are coded No measurable speed difference Originally committed as revision 21931 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	a89264761f	Handle Theora's continued runs in superblock coding. This doesn't really matter yet since 4:2:0 1080p has only 3060 superblocks, but larger resolutions or 4:4:4 1080p could hit this case. Originally committed as revision 21930 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	855c720c86	Decode fully coded superblocks in the same manner as partial superblocks and qpi No speed difference, but it will simplify the special 4129 case. Originally committed as revision 21929 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	ecb51b25bb	Make the special 4129 case for long-run bit strings a #define and explain it Originally committed as revision 21928 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	33dbc1b7ca	Use memset to set the runs partially coded superblocks Much faster for long runs (e.g. nearly uncoded frames), slightly faster for the general case. Originally committed as revision 21927 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	40d1122752	Use LOCAL_ALIGNED macro for local arrays Originally committed as revision 21866 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

David Conrad	7c2e31d1f0	Move branch based on custom mode outside the loop Originally committed as revision 21804 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	eb691ef219	Directly check whether a fragment is coded for 4MV mode instead of iterating through the entire coded fragment list. Originally committed as revision 21803 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	15675ce609	Eliminate fragment -> macroblock mapping array Originally committed as revision 21802 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

David Conrad	19cd517dbf	Eliminate superblock <-> macroblock mapping array Originally committed as revision 21800 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	735acf567c	Don't pre-calculate first_pixel 3.6% faster on Elephants_Dream_HD-q7-aq7.ogg on my penryn Originally committed as revision 21781 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	a8de390163	Implement CODEC_CAP_DRAW_HORIZ_BAND for VP3 decoder Originally committed as revision 21780 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
