* rv34: Avoid NULL dereference on corrupted bitstreamLaurent Aimar2011-09-19
| | | | | | rv34_decode_slice() can return without allocating any pictures. Signed-off-by: Martin Storsjö <martin@martin.st>
* Fixed size given to init_get_bits().Laurent Aimar2011-09-15
| | | | | | | init_get_bits() takes a number of bits and not a number of bytes as its size argument. Signed-off-by: Alex Converse <alex.converse@gmail.com>
* rv34: check that subsequent slices have the same type as first one.Kostya Shishkov2011-09-12
| | | | | | | | This prevents some crashes when corrupted bitstream reports e.g. P-type slice in I-frame. Official RealVideo decoder demands all slices to be of the same type too. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* Correct chroma vector calculation for RealVideo 3.Kostya Shishkov2011-08-02
| | | | | | | Old version divided it wrong, which resulted in chroma drift (visible on FATE sample too as dirty trails left by clouds). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Eliminate FF_COMMON_FRAME macro.Diego Biurrun2011-07-11
| | | | | FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.
* Remove unused static tables and static inline functions.Diego Biurrun2011-07-04

* doxygen: Prefer member groups over grouping into modulesReinhard Tartler2011-07-02
| | | | | | | | | Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.
* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* lavc: mark hurry_up for removal on next major bumpAnton Khirnov2011-04-02
| | | | | It has been deprecated for about five years, skip_idct/skip_frame should be used instead.

* 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
* Revert commit 22378.Vitor Sessak2010-03-09

* Zeroing pic->motion_val in RV3/4 causes alignment problems on some 64-bitKostya Shishkov2009-08-30
| | | | | | | architectures since stride is multiple of 4 and not of 8, so split fill_rectangle() calls to operate on 32-bit words instead of 64-bit ones. Originally committed as revision 19744 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Revert changing VLC initialization type for RV3/4 decoder.Kostya Shishkov2009-04-27
| | | | | | | While using large static table is not good (especially for embedded devices and CPUs with small cache), other alternatives are not very good either. Originally committed as revision 18696 to svn://svn.ffmpeg.org/ffmpeg/trunk

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