Michael Niedermayer	cf48b00640	cavsdec: check for value in get_ue_code() Fixes integer overflow and prints an error in case the value is invalid. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Anton Khirnov	fb0cb11f09	cavsdec: export picture type in the output frame	12 years ago
Anton Khirnov	7d84826400	cavs: deMpegEncContextize It does not use any of the mpegvideo infrastructure, just a few fields from the context. Fixes a segfault with the emu edge flag, since emu edge buffer is now allocated as a part of the frame buffer allocation and cavs calls ff_get_buffer() directly, it does not use mpegvideo buffer management. Fixes a memleak of the last frame.	12 years ago
Anton Khirnov	185c2ef849	cavsdec: cosmetics, reformat	12 years ago
Michael Niedermayer	eee8c94f50	cavsdec: check ff_get_buffer() return value Fixes CID747721 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Martin Storsjö	eaa9b2e66c	avcodec: Rename avpriv_frame_rate_tab to ff_mpeg12_frame_rate_tab This table doesn't need to be shared with libavformat any longer. Add mpeg12 to the name to make it less ambiguous, while renaming it. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	f75f4194d1	Restructure av_log_missing_feature message Some invocations include a verb in the log message, others do not. Yet av_log_missing_feature expects callers to provide a verb. Change the function to include a verb instead and update the callers accordingly. The result is a more natural function API and correct English in the function invocations.	12 years ago
Michael Niedermayer	c20a696306	cavsdec: check for changing w/h. Our decoder does not support changing w/h. Fixes CVE-2012-2777 and CVE-2012-2784. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Michael Niedermayer	7ea5dbcb83	cavsdec: Fix assertion failure. The assert in decode_mb_b() is replaced by a normal error check for the case that can occur with a damaged or crafted bitstream. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Mans Rullgard	6efb698883	cavsdsp: set idct permutation independently of dsputil CAVS uses its own idct so using dsputil to set the permutation is fragile. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Ronald S. Bultje	83f15a1228	avs: fix infinite loop on end-of-stream. The codec would keep returning the last decoded frame if the stream contains B-frames, since it wouldn't clear that frame from the list of frames to be returned to the user. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Måns Rullgård	f079a64aea	Move cavs dsp functions to their own struct Originally committed as revision 24685 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefan Gehrer	35122bd93e	add heuristic to discern the old sample clips from streams encoded with rm52j encoder, a marker_bit has been added in the I-Frame syntax Originally committed as revision 21836 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefan Gehrer	470de55aa1	fix slice header checking Originally committed as revision 19303 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 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. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefan Gehrer	cd3356ff73	check for a stuffing byte at the end of a slice Originally committed as revision 17559 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
