Ronald S. Bultje	fc9bc08dca	Indeo3: fix crashes on corrupt bitstreams. Splits at borders of cells are invalid, since it leaves one of the cells with a width/height of zero. Also, propagate errors on buffer allocation failures, so we don't continue decoding (which crashes). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Hendrik Leppkes	6071644287	indeo3: fix motion vector validation The index of the motion vector has to be checked before being multiplied by 2 for the array index. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Diego Biurrun	124e28847b	Remove some stray unnecessary ffmpeg references.	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Stefano Sabatini	48df6a2415	indeo3: add out-of-buffer write check Prevent out-of-buffer writes. In particular fix smclocki32.avi.1.1 crash, trac issue #114, roundup issue #1482.	14 years ago

Stefano Sabatini	a469c32478	indeo3: add @file doxy and a link to multimedia wiki documentation	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
Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	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.

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

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
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

Reimar Döffinger	16c8318513	Reallocate internal buffer when coded frame size changes. Fixes out-of-bounds reads and writes with i32/smclocki32.avi.1.0 from issue 1240. Originally committed as revision 19359 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	28bcc76ab7	Change iv_decode_frame to get AVCodecContext as argument, so that avcodec_check_dimensions can be called with a proper context instead of NULL. Originally committed as revision 19358 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Baptiste Coudurier	7bbf3f2ca4	indeo3 decoder uses get_buffer, set CODEC_CAP_DR1 Originally committed as revision 19090 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
