* VP3: remove an unnecessary static variableAlexander Strange2011-01-171-4/+2
| | | | Originally committed as revision 26398 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove dead code in theora_decode_tablesJason Garrett-Glaser2010-10-261-8/+2
| | | | | | | Reading 7 bits as an unsigned int can't result in a value exceeding 127. Accordingly, remove error message (as it'll never be reached). Originally committed as revision 25575 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Reindent after r25573Jason Garrett-Glaser2010-10-261-6/+6
| | | | Originally committed as revision 25574 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix Theora decoding bug if loopfilter is completely disabledJason Garrett-Glaser2010-10-261-0/+2
| | | | | | | | | | Bug caused by the fact that get_bits(gb, 0) is undefined. Doesn't affect any streams generated by the official Theora encoder, but such streams are nevertheless valid. Fixes decoding of CELT-933dd833-nmr-bandt.ogv. Originally committed as revision 25573 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Only draw the actually visible area in vp3_draw_horiz_band.Reimar Döffinger2010-09-081-4/+2

* Fix slice height for y position calculation for vp3_draw_horiz_bandReimar Döffinger2010-09-061-1/+1
| | | | | | when the video uses 4:2:2 instead of 4:2:0 coding. Originally committed as revision 25052 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix vp3_draw_horiz_band to not produce completely chaotical valuesReimar Döffinger2010-09-061-1/+1
| | | | | | | that result in overdrawing areas again and again if s->flipped_image is false. Originally committed as revision 25051 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP3/Theora: validate aspect and reduce it before exporting itReimar Döffinger2010-09-061-3/+8
| | | | | | via the context. Originally committed as revision 25050 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove use of the deprecated function avcodec_check_dimensions(), useStefano Sabatini2010-08-061-1/+2
| | | | | | av_check_image_size() instead. Originally committed as revision 24711 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix vp3_draw_horiz_band to calculate chroma offsets correctlyReimar Döffinger2010-06-081-1/+1
| | | | | | for 4:2:2 and 4:4:4 formats. Originally committed as revision 23537 to svn://svn.ffmpeg.org/ffmpeg/trunk
* vp3: Skip the loop filter when strength is 0 or when requestedDavid Conrad2010-05-271-1/+6
| | | | Originally committed as revision 23346 to svn://svn.ffmpeg.org/ffmpeg/trunk
* theora: Don't read an excess bit for maximum length long bit runs if the runDavid Conrad2010-05-251-18/+24
| | | | | | exactly ends the remaining blocks. Originally committed as revision 23304 to svn://svn.ffmpeg.org/ffmpeg/trunk
* theora: coeff huffman codes are allowed to be up to 32 bits long (for 32 tokens)David Conrad2010-04-211-23/+23
| | | | Originally committed as revision 22931 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-201-1/+1
| | | | | | | | 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

| | | | | | is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 22494 to svn://svn.ffmpeg.org/ffmpeg/trunk
* vp3: avoid buffer overread in coeff decodeDavid Conrad2010-03-101-1/+1
| | | | | | | 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
* vp3: correctly clip vp3_draw_horiz_band callDavid Conrad2010-03-091-1/+1

* vp3: be less spammy on broken filesDavid Conrad2010-03-091-1/+1
| | | | Originally committed as revision 22356 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård2010-03-061-2/+2
| | | | | | | 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
* Really fix 2.95David Conrad2010-03-041-1/+2
| | | | Originally committed as revision 22204 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Maybe fix gcc 2.95David Conrad2010-03-041-1/+1
| | | | Originally committed as revision 22203 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Delay translating DCT tokens into coefficients until immediately before IDCTDavid Conrad2010-03-031-178/+177
| | | | | | | | 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
* Do MC and IDCT in coding (hilbert) orderDavid Conrad2010-03-031-26/+43
| | | | | | | | | | 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
* Explictly separate decoding whether fragments are coded by planeDavid Conrad2010-03-031-11/+16
