* mjpeg: abort decoding if packet is too large.Ronald S. Bultje2012-02-24
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* mjpegdec: parse RSTn to prevent skipping other data in mjpeg_decode_scanJanne Grunau2012-01-05
| | | | | | | Check explicitly if enough bits are left to prevent an infinite loop when the bitstream buffer is not followed by zero-padding. Based on patches by Michael Niedermayer <michaelni@gmx.at>.
* mov: Don't stick the QuickTime field ordering atom in extradata.Alex Converse2011-12-21
| | | | | | The 'fiel' atoms can be found in H.264 tracks clobbering the extradata. MJPEG supports non field based extradata, and this data should be preserved when copying.
* Fix a bunch of common typos.Diego Biurrun2011-12-11

* lavc: replace references to deprecated AVCodecContext.error_recognition to ↵Dustin Brody2011-10-22

* mjpegdec: add 'extern_huff' private option.Anton Khirnov2011-08-31
| | | | Deprecate CODEC_FLAG_EXTERN_HUFF
* mjpeg: treat external huffman table setup failure as codec init failure if ↵Dustin Brody2011-08-31
| | | | | | external huffman table use requested Signed-off-by: Anton Khirnov <anton@khirnov.net>
* mjpeg: propagate decode errors from ff_mjpeg_decode_sos and ff_mjpeg_decode_dqtDustin Brody2011-08-11
| | | | Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29
| | | | It's more readable and less prone to breakage.
* jpegdec: actually search for and parse RSTnMichael Niedermayer2011-07-23
| | | | | | | | | | | | | Fixes decoding of MJPEG files produced by some UVC Logitec web cameras, such as "Notebook Pro" and "HD C910".

* Set maximum lowres value for the MJPEG decoder to 3.Carl Eugen Hoyos2011-02-16
| | | | | | | While 4 works for some samples, 3 is the correct value since 8x8 DCT is used by (m)jpeg. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* Replace dprintf with av_dlogLuca Barbato2011-01-29
| | | | dprintf clashes with POSIX.1-2008
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Sanitise get_bits macros, part 1Mans Rullgard2011-01-23
| | | | | | | | | Some of the macros in get_bits.h include a final semicolon, some do not. This removes these or adds do {} while(0) around the macros as appropriate and adds semicolons where needed in calling code. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Fix undefined expressions that use multiple calls to get_bits().Alex Converse2010-08-24
| | | | | | | | | Because the order of evaluation of subexpressions is undefined, two get_bits() calls may not be part of the same expression. See also r24902. Originally committed as revision 24906 to svn://svn.ffmpeg.org/ffmpeg/trunk

* bswap: change ME to NE in macro namesMåns Rullgård2010-07-10
| | | | | | | Other parts of FFmpeg use NE (native endian) rather than ME (machine). This makes it consistent. Originally committed as revision 24169 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
