Michael Niedermayer	2d09cdbaf2	indeo5: check tile size in decode_mb_info(). This prevents writing into a too small array if some parameters changed without the tile being reallocated. Fixes CVE-2012-2794 CC:libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Michael Niedermayer	891918431d	indeo5dec: Make sure we have had a valid gop header. This prevents decoding happening on a half initialized context. Fixes CVE-2012-2779 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Michael Niedermayer	af38823709	indeo5: set transform_size like indeo4 does to prevent useage of too large transforms. I dont know if this is needed, its a precautionary change. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Janne Grunau	366ac22ea5	indeo5: prevent null pointer dereference on broken files Found by John Villamil <johnv@matasano.com>	13 years ago
Diego Biurrun	00a1cdd264	Place some START_TIMER invocations in separate blocks. This fixes compilation failures related to START_TIMER/STOP_TIMER macros and -Werror=declaration-after-statement. START_TIMER declares variables and thus may not be placed after statements outside of a new block.	13 years ago
Michael Niedermayer	f41a6c8f3a	indeo5: Fix null pointer dereferences of ref_mb Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	d46bc4133c	indeo5: Fix crash due to partially initialized gop vars. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	aaf47bcde7	Drop ALT_ prefix from BITSTREAM_READER_LE name. The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.	13 years ago
Diego Biurrun	f190f676bc	Replace custom DEBUG preprocessor trickery by the standard one.	14 years ago
Stefano Sabatini	01042d4123	lavc: set defaults in internal codec frames This is required specifically for setting frame->format to -1, otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading the format from the output decoded frame will get misled. In particular fix regressions occurring with the pending vsrc_buffer patch.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago

Maxim Poliakovski	220f2bd9c5	move indeo5 scan patterns into ivi_common.c so those can be shared by indeo4. Originally committed as revision 23335 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

Maxim Poliakovski	7fcb98a7ec	Band quant tables should not be assigned inside band tile loop, one time is enough. Patch by Maxim (max_pole, gmx de) Originally committed as revision 22279 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	e322aacedd	Encapsulate VLC information needed for decoding blocks and macroblocks in Indeo 5 into single structure IVIHuffTab and factorize code using it. Based on patch by Maxim (max_pole at German GMX) Originally committed as revision 22092 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	60819e694e	10l trocadero: Indeo 5 decoder did not free custom VLCs for macroblock and block decoding at exit, so prevent that memory leak now. Originally committed as revision 21983 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	9068f36dcc	Macroblock and block Huffman code sets are to be used by both Indeo 4 and Indeo 5, so make them global and move their initialization to the common place as well. And fix static VLC initialization, as ff_ivi_create_huff_from_desc() used old way to do so. Originally committed as revision 21962 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
