* vlc/rl: Add ff_ prefix to the nonstatic symbolsMartin Storsjö2012-02-15
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* vp3: fix streams with non-zero last coefficientJanne Grunau2012-01-05
| | | | Fixes a regression introduced in 8b94df0f2047e972.
* vp3dec: Check coefficient index in vp3_dequant()Reinhard Tartler2011-12-23
| | | | | | | | | Based on a patch by Michael Niedermayer <michaelni@gmx.at> Fixes NGS00145, CVE-2011-4352 Found-by: Phillip Langlois Signed-off-by: Reinhard Tartler <siretart@tauware.de>
* vp3: Reorder some functions to fix VP3 build with Theora disabled.Diego Biurrun2011-12-20

* avcodec: change number of plane pointers from 4 to 8 at next major bump.Justin Ruggles2011-12-02
| | | | | | Add AV_NUM_DATA_POINTERS to simplify the bump transition. This will allow for supporting more planar audio channels without having to allocate separate pointer arrays.
* avcodec: move some AVCodecContext fields to an internal struct.Justin Ruggles2011-11-19
| | | | | | | | A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.
* vp3: remove some pointless commentsDiego Biurrun2011-11-02
|
* vp3: fix oob read for negative tokens and memleaks on error.Ronald S. Bultje2011-10-28
|
* lavc: use avpriv_ prefix for ff_split_xiph_headers.Anton Khirnov2011-10-20
| | | | It's used in lavf.
* w32threads: support for frame multithreadingSteven Walters2011-10-16
| | | | | | | | Replace our incomplete w32threads implementation with x264's pthreads w32threads wrapper. Relicensed to LGPL with kind permission by Pegasys Inc. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* doxygen: fix wrong comment syntax, //< vs. ///<Diego Biurrun2011-08-26
|
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29
| | | | It's more readable and less prone to breakage.
* vp3/theora: flush after seek.Ronald S. Bultje2011-07-28

* Replace deprecated FF_*_TYPE symbols with AV_PICTURE_TYPE_*.Stefano Sabatini2011-05-02

* 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.

* 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>

* 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

* 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.
