Anton Khirnov	ae3da0ae55	indeo4/5: check empty tile size in decode_mb_info(). This prevents writing into a too small array if some parameters changed without the tile being reallocated. Based on a patch by Michael Niedermayer <michaelni@gmx.at> Fixes CVE-2012-2800 CC:libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	12 years ago
Anton Khirnov	5d2170c53b	ivi_common: make ff_ivi_process_empty_tile() static. It's not used outside of ivi_common.c	12 years ago
Michael Niedermayer	b146d74730	indeo4: update AVCodecContext width/height on size change Fixes CVE-2012-2787 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 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>	13 years ago

Diego Biurrun	b1563d0cf9	ivi_common: Initialize a variable at declaration in ff_ivi_decode_blocks(). This simplifies the code a bit and avoids an uninitialized variable warning.	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

Daniel Kang	eb40d7ffa7	Check symbol validity to avoid a crash, fixes issue 2523. Patch by Daniel Kang, daniel.d.kang at gmail Originally committed as revision 26360 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	49bd8e4b84	Fix grammar errors in documentation Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Maxim Poliakovski	79d46cbea6	Quant changes only once per MB so move the corresponding scale factor assignment out of the block decoding loop. Indeo4 doesn't use any scale table but the quant level itself as scale. Therefore access scale table only if its pointer != NULL. Originally committed as revision 23569 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Maxim Poliakovski	0933f55829	Prepare Indeo4 (step 1): upscale indeo5 base tables by 2 and convert those into uint16_t. Originally committed as revision 23523 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Maxim Poliakovski	274793de6e	Make dequantization equation use less registers on some CPUs. Originally committed as revision 23391 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Maxim Poliakovski	9c6b3b97d7	Add the forgotten ff_ prefix to the shareable scan patterns. Originally committed as revision 23341 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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
Maxim Poliakovski	5f1654b25b	Scale tile dimensions in case both local decoding and scalability mode are used in Indeo 5 stream. Patch by Maxim ($indeo5dec_author) Originally committed as revision 22318 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Maxim Poliakovski	e7edeb9191	When tracking non-zero coefficients during Indeo 5 decoding, make sure it does not ignore coefficient value = 256. Patch by Maxim ((!min)_pole \at gmx dot/ de) Originally committed as revision 22275 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	4982a77e56	Make it clear that ff_ivi_init_static_vlc() does not need arguments Originally committed as revision 22091 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
Måns Rullgård	2fc492d842	Declare indeo VLC table storage with correct type Originally committed as revision 21977 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
Kostya Shishkov	1cf3168516	Indeo Video Interactive 4 and 5 common code and DSP functions. Reviewed and corrected by myself because there were no other volunteers in the last weeks. Originally committed as revision 21531 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
