* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19

* vp3-mt: fix deadlock when first frame is not a keyframe.Ronald S. Bultje2011-03-02

* Fix VP3 edge emulationDavid Conrad2011-02-19
| | | | | | With negative stride, the start of the edge_emu buffer should be pointing to the last line, not the end of the buffer. With positive stride, pointing to the end of the buffer was completely wrong.
* VP3: fix decoding of videos with stride > 2048Jason Garrett-Glaser2011-02-18
| | | | | Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't use an MPEG-like quantizer scale.
* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* vp3: Frame-based multithreading supportAlexander Strange2011-02-09
| | | | | | | | | | | | | | | | | | | Decode times for big_buck_bunny_720p_stereo: 1 thread: real 1m14.227s user 1m13.104s sys 0m1.108s 2 threads: (33% faster) real 0m49.329s user 1m33.735s sys 0m1.834s 3 threads: (44% faster) real 0m41.593s user 1m44.884s sys 0m1.967s

* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* VP3: remove an unnecessary static variableAlexander Strange2011-01-17
| | | | Originally committed as revision 26398 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove dead code in theora_decode_tablesJason Garrett-Glaser2010-10-26
| | | | | | | 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-Glaser2010-10-26
| | | | Originally committed as revision 25574 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix Theora decoding bug if loopfilter is completely disabledJason Garrett-Glaser2010-10-26
| | | | | | | | | | 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 Döffinger2010-09-08

* Fix vp3_draw_horiz_band to not produce completely chaotical valuesReimar Döffinger2010-09-06
| | | | | | | 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 Döffinger2010-09-06
| | | | | | 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 Sabatini2010-08-06
| | | | | | av_check_image_size() instead. Originally committed as revision 24711 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | 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
