Carl Eugen Hoyos	2e3c56a29f	Set maximum lowres value for the MJPEG decoder to 3. 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>	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil 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.

Luca Barbato	dfd2a005eb	Replace dprintf with av_dlog dprintf clashes with POSIX.1-2008	14 years ago
Diego Elio Pettenò	d36beb3f69	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>	14 years ago
Mans Rullgard	bf5f9b528b	Sanitise get_bits macros, part 1 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>	14 years ago

Michael Niedermayer	2111a191eb	Check index in mjpeg AC decode against overflowing. This fixes a possibly exploitable buffer overflow and it will likely also be needed for future overreading fixes. Originally committed as revision 25546 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Michael Niedermayer	5675a11f92	Add a seperate VLC table for progressive jpeg so we dont have to subtract 16 in the inner loop. Originally committed as revision 25545 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Alex Converse	4c399dc82b	Fix undefined expressions that use multiple calls to get_bits(). 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	14 years ago
Stefano Sabatini	6ce9b4310c	Remove use of the deprecated function avcodec_check_dimensions(), use av_check_image_size() instead. Originally committed as revision 24711 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	e6b22522c9	bswap: change ME to NE in macro names 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	15 years ago
Carl Eugen Hoyos	0fd0ef7947	Add new decoder property max_lowres and do not init decoder if requested value is higher. Originally committed as revision 24098 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

Michael Niedermayer	49b19191bc	Lossless jpeg expects and uses BGRA not RGB32 (this probably caused a problem on big endian) Originally committed as revision 20789 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	98c82d6910	Allocate pictures with enough padding for jpeg. Ensure that jpeg does not use mbs that could require larger padding. This might have been exploitable. Originally committed as revision 20566 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	b711aaa2d8	Disable image flipping during JPEG decoding if CODEC_FLAG_EMU_EDGE is set instead of either aborting on the assert or crashing due to writing beyond the array due to insufficient padding. Originally committed as revision 20552 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
