2011-09-19rv34: Avoid NULL dereference on corrupted bitstreamLaurent Aimar
rv34_decode_slice() can return without allocating any pictures. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-09-16Fixed size given to init_get_bits().Laurent Aimar
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>
2011-09-12rv34: check that subsequent slices have the same type as first one.Kostya Shishkov
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>
2011-08-13rv34: free+allocate buffer instead of reallocating it to preserve alignmentKostya Shishkov

2011-08-02Correct chroma vector calculation for RealVideo 3.Kostya Shishkov
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>
2011-07-11Eliminate FF_COMMON_FRAME macro.Diego Biurrun
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.
2011-07-04Remove unused static tables and static inline functions.Diego Biurrun
2011-07-02doxygen: Prefer member groups over grouping into modulesReinhard Tartler
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.
2011-05-10Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson
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>
2011-05-02Replace deprecated FF_*_TYPE symbols with AV_PICTURE_TYPE_*.Stefano Sabatini

2011-04-26lavc: remove FF_API_HURRY_UP cruftAnton Khirnov
2011-04-02lavc: mark hurry_up for removal on next major bumpAnton Khirnov
It has been deprecated for about five years, skip_idct/skip_frame should be used instead.

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
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
2010-03-09Revert commit 22378.Vitor Sessak
It broke FATE and kostya asked me on IRC to revert it. Originally committed as revision 22379 to svn://svn.ffmpeg.org/ffmpeg/trunk

nonexisting reference. Originally committed as revision 22378 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-08-30Zeroing pic->motion_val in RV3/4 causes alignment problems on some 64-bitKostya Shishkov
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

its stride and offset to always have align 4. Originally committed as revision 19316 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-27Revert changing VLC initialization type for RV3/4 decoder.Kostya Shishkov
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

Originally committed as revision 18637 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
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. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
