Janne Grunau	94235f2ba2	indeo3: avoid writes without necessary alignment in copy_cell() Cells starting at a position aligned to 8 pixels but wider than 4 blocks are copied with 3 blocks per loop. This creates problems on the next loop iterations since the routine copying 2 blocks requires the same alignment on some architectures like ARM NEON.	12 years ago
Anton Khirnov	a97d8cc16e	indeo3: use unaligned reads on reference blocks. They are not guaranteed to be aligned. Fixes Bug 503. CC:libav-stable@libav.org	12 years ago
Anton Khirnov	bda9e6d923	indeo3: use put_pixels instead of put_no_rnd_pixels in copy_cell() They are the same in this case, except put_pixels also has blocksizes smaller than 8.	12 years ago
Anton Khirnov	95220be1fa	indeo3: fix off by one in MV validity check CC:libav-stable@libav.org	12 years ago
Ronald S. Bultje	8f992dc8c7	indeo3: Use hpeldsp instead of dsputil for half-pel functions This makes the Indeo 3 decoder independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	a0a872d073	indeo3: check motion vectors. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago
Anton Khirnov	34e6af9e20	indeo3: fix data size check The data offsets are relative to the bistream header, which is 16 bytes after the start of the data. Fixes invalid reads with corrupted files. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago
Anton Khirnov	66531d634e	indeo3: switch parsing the header to bytestream2 Also add an additional sanity check to the alt_quant table. Fixes invalid reads with corrupted files. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago
Diego Biurrun	6d97484d72	avcodec: av_log_ask_for_sample() ---> avpriv_request_sample()	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Mans Rullgard	b9ee5f2cab	indeo3: replace use of copy_block4 with put_pixels The destination is sufficiently aligned for put_pixels here. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Anton Khirnov	bff5e5f8b3	indeo3: remove duplicate capabilities line.	12 years ago
Anton Khirnov	f174fbac3c	lavc: add CODEC_CAP_DR1 to all video decoders missing them	12 years ago
Kostya Shishkov	169514c440	indeo3: do not try to output more lines than we can fit Internally chroma planes have multiple of four height while allocated image planes might be smaller if CODEC_FLAG_EMU_EDGE is set. Thus we should not output more lines of chroma than frame can accept. Also the decoder can be safely switched to direct rendering now.	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Anton Khirnov	e4d4044339	indeo3: fix out of cell write. Fixes CVE-2012-2776. CC:libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Kostya Shishkov	6de226a2b8	indeo3: validate new frame size before resetting decoder	13 years ago
Kostya Shishkov	bc00da2701	indeo3: when freeing buffers, set pointers referencing them to NULL as well	13 years ago
Kostya Shishkov	81064a8045	indeo3: initialise pixel planes on allocation This prevents decoder from reading garbage from it in case of errors later.	13 years ago
Kostya Shishkov	fc417db3f1	indeo3: ensure that decoded cell data is in 7-bit range as presumed by decoder	13 years ago
Hendrik Leppkes	4b7fa553a9	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> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago
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
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 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	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	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
Stefano Sabatini	e16f217ceb	Use new imgutils.h API names, fix deprecation warnings. Originally committed as revision 25058 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	14 years ago
Måns Rullgård	8fc0162ac4	Add av_ prefix to bswap macros Originally committed as revision 24170 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
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
Måns Rullgård	63613fe615	Replace WORDS_BIGENDIAN with HAVE_BIGENDIAN Originally committed as revision 19508 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Reimar Döffinger	4f76697b3e	Change av_free to av_freep Originally committed as revision 19360 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 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. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
