* | ivi_common: check that scan pattern is set before using it. | Anton Khirnov | 2012-12-14 |
| | | | | | | Fixes CVE-2012-2791. CC: libav-stable@libav.org | ||
* | ivi_common: use proper logging context in ivi_decode_blocks(). | Anton Khirnov | 2012-12-14 |
| | |||
* | ivi_common: make some functions and tables static. | Anton Khirnov | 2012-12-14 |
| | |||
* | lavc: fix decode_frame() third parameter semantics for video decoders | Anton Khirnov | 2012-12-04 |
| | | | | It's got_frame, not data size | ||
* | lavc: add a wrapper for AVCodecContext.get_buffer(). | Anton Khirnov | 2012-12-04 |
| | | | | It will be useful in the upcoming transition to refcounted AVFrames. | ||
* | ivi_common: Drop unused function parameter from decode_band() | Diego Biurrun | 2012-10-26 |
| | |||
* | Move av_reverse table to libavcodec | Diego Biurrun | 2012-10-12 |
| | | | | It is only used in that library. | ||
* | indeo4/5: remove constant parameter num_bands from wavelet recomposition | Janne Grunau | 2012-10-10 |
| | | | | Fixes bogus uninitialized value compiler and coverity warnings. | ||
* | indeo4/5: check empty tile size in decode_mb_info(). | Anton Khirnov | 2012-09-29 |
| | | | | | | | | | | | | | 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 | ||
* | ivi_common: make ff_ivi_process_empty_tile() static. | Anton Khirnov | 2012-09-29 |
| | | | | It's not used outside of ivi_common.c | ||
* | indeo4: update AVCodecContext width/height on size change | Michael Niedermayer | 2012-09-29 |
| | | | | | | | Fixes CVE-2012-2787 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Anton Khirnov <anton@khirnov.net> | ||
* | indeo5dec: Make sure we have had a valid gop header. | Michael Niedermayer | 2012-09-29 |

* | Replace all CODEC_ID_* with AV_CODEC_ID_* | Anton Khirnov | 2012-08-07 |
| | |||
* | indeo: Make ivi_calc_band_checksum() static, it is only used in one file. | Diego Biurrun | 2012-05-20 |
| | |||

| | |||
* | ivi_common: Initialize a variable at declaration in ff_ivi_decode_blocks(). | Diego Biurrun | 2012-04-20 |
| | | | | This simplifies the code a bit and avoids an uninitialized variable warning. | ||
* | cosmetics: Consistently place static, inline and av_cold attributes/keywords. | Diego Biurrun | 2012-04-04 |
| | |||
* | vlc/rl: Add ff_ prefix to the nonstatic symbols | Martin Storsjö | 2012-02-15 |
| | | | | Signed-off-by: Martin Storsjö <martin@martin.st> | ||

| | | | | | | Bug found by: Oana Stratulat Signed-off-by: Janne Grunau <janne-libav@jannau.net> | ||
* | Drop ALT_ prefix from BITSTREAM_READER_LE name. | Diego Biurrun | 2011-12-22 |
| | | | | | The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore. | ||
* | Replace custom DEBUG preprocessor trickery by the standard one. | Diego Biurrun | 2011-06-03 |
| | |||

* | Check symbol validity to avoid a crash, fixes issue 2523. | Daniel Kang | 2011-01-15 |
| | | | | | | Patch by Daniel Kang, daniel.d.kang at gmail Originally committed as revision 26360 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||

* | Quant changes only once per MB so move the corresponding scale factor assignment | Maxim Poliakovski | 2010-06-10 |
| | | | | | | | 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 | ||
* | Prepare Indeo4 (step 1): upscale indeo5 base tables by 2 and convert those ↵ | Maxim Poliakovski | 2010-06-08 |
| | | | | | | into uint16_t. Originally committed as revision 23523 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||

| | | | | Originally committed as revision 23391 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||
* | Add the forgotten ff_ prefix to the shareable scan patterns. | Maxim Poliakovski | 2010-05-26 |
| | | | | Originally committed as revision 23341 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||
* | move indeo5 scan patterns into ivi_common.c | Maxim Poliakovski | 2010-05-26 |
| | | | | | | so those can be shared by indeo4. Originally committed as revision 23335 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||
* | Remove explicit filename from Doxygen @file commands. | Diego Biurrun | 2010-04-20 |
| | | | | | | | | 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 | ||
* | Scale tile dimensions in case both local decoding and scalability mode | Maxim Poliakovski | 2010-03-08 |
| | | | | | | | are used in Indeo 5 stream. Patch by Maxim ($indeo5dec_author) Originally committed as revision 22318 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||
* | When tracking non-zero coefficients during Indeo 5 decoding, make sure | Maxim Poliakovski | 2010-03-07 |
| | | | | | | | 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 | ||
* | Encapsulate VLC information needed for decoding blocks and macroblocks in | Kostya Shishkov | 2010-02-27 |
| | | | | | | | | 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 | ||
* | Make it clear that ff_ivi_init_static_vlc() does not need arguments | Kostya Shishkov | 2010-02-27 |
| | | | | Originally committed as revision 22091 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||
* | 10l trocadero: Indeo 5 decoder did not free custom VLCs for macroblock and | Kostya Shishkov | 2010-02-23 |
| | | | | | | block decoding at exit, so prevent that memory leak now. Originally committed as revision 21983 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||
* | Declare indeo VLC table storage with correct type | Måns Rullgård | 2010-02-23 |
| | | | | Originally committed as revision 21977 to svn://svn.ffmpeg.org/ffmpeg/trunk | ||
* | Macroblock and block Huffman code sets are to be used by both Indeo 4 and | Kostya Shishkov | 2010-02-22 |
| | | | | | | | | 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 | ||
* | Indeo Video Interactive 4 and 5 common code and DSP functions. | Kostya Shishkov | 2010-01-30 |
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 |
