* indeo3: validate new frame size before resetting decoderKostya Shishkov2012-05-15

* indeo3: when freeing buffers, set pointers referencing them to NULL as wellKostya Shishkov2012-05-15
|
* indeo3: initialise pixel planes on allocationKostya Shishkov2012-05-15
| | | | This prevents decoder from reading garbage from it in case of errors later.
* indeo3: ensure that decoded cell data is in 7-bit range as presumed by decoderKostya Shishkov2012-05-15

* indeo3: fix motion vector validationHendrik Leppkes2012-05-01
| | | | | | | | The index of the motion vector has to be checked before being multiplied by 2 for the array index. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* Indeo3: fix crashes on corrupt bitstreams.Ronald S. Bultje2012-02-28
| | | | | | | | | Splits at borders of cells are invalid, since it leaves one of the cells with a width/height of zero. Also, propagate errors on buffer allocation failures, so we don't continue decoding (which crashes). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* indeo3: error out if no motion vector is set.Aneesh Dogra2011-11-27

* indeo3: Fix a fencepost error.Alex Converse2011-11-08
| | | | Found with asan and the venerable 1-dog.avi sample.
* replacement Indeo 3 decoderMaxim Poliakovski2011-11-03
| | | | | | | The new decoder is much smaller and has better code quality. Cleanup and fixes courtesy of Kostya Shishkov. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29

* 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>
* Use new imgutils.h API names, fix deprecation warnings.Stefano Sabatini2010-09-07

| | | | Originally committed as revision 24170 to svn://svn.ffmpeg.org/ffmpeg/trunk
* bswap: change ME to NE in macro namesMåns Rullgård2010-07-10
| | | | | | | Other parts of FFmpeg use NE (native endian) rather than ME (machine). This makes it consistent. Originally committed as revision 24169 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini2010-03-30

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