Diego Biurrun	c697c590fb	lcl: Disentangle pointers to input data and decompression buffer This is cleaner and avoids a cast plus a related const qualifier warning.	10 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Michael Niedermayer	1e00bbb10c	avcodec/lcldec: Check that dimensions are a multiple of the subsample factors Other dimensions would not work correctly currently, also ask for a sample for files that fail this check. This fixes an integer overflow leading to out of array accesses. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Paul B Mahol	1b3dbe3f75	lcldec: fix decoding of uncompressed rgb24 sample Sample from ticket #1216 does not use any compression but bitstream claims it is. Reference decoder decodes sample just fine. Fixes #1216. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Diego Biurrun	5bac2d0c30	avutil: Move memcpy_backptr() to mem.c The function is used elsewhere and does not belong with the LZO code.	12 years ago
Diego Biurrun	e831b3b852	av_memcpy_backptr: Drop no longer necessary malloc padding Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Ronald S. Bultje	bd17a40a7e	lcl: return negative error codes on decode_init() errors. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	be129271ea	lcl: error out if uncompressed input buffer is smaller than framesize. This prevents crashes when trying to read beyond the end of the buffer while decoding frame data. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	01cb62aba2	lcl: don't overwrite input memory. If the PNG filter is enabled, a PNG-style filter will run over the input buffer, writing into the buffer. Therefore, if no zlib compression was used, ensure that we copy into a temporary buffer, otherwise we overwrite user-provided input data.	13 years ago
Reimar Döffinger	42a1f1d7a8	Avoid uninitialized data in lcldec when ofs is 0 in MSZH. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	13 years ago
Diego Biurrun	adbfc605f6	doxygen: Consistently use '@' instead of '\' for Doxygen markup. Signed-off-by: Diego Biurrun <diego@biurrun.de>	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

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

Diego Biurrun	b34aaed2cf	Move #ifdef before zlib_decomp() up so it covers the Doxygen comments. Otherwise Doxygen gets confused and cannot map comments to functions. Originally committed as revision 23988 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
Reimar Döffinger	4a49ab77c6	Remove unnecessary calls to avcodec_check_dimensions, the check is already done at a higher level. Originally committed as revision 20229 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	24dd21fa41	add #if CONFIG_ZLIB_DECODER around zlib_decomp function. Fixes compilation when zlib is not available. Originally committed as revision 19069 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	79183d3c3e	mszh decompression: add a special case for an all-0 mask, i.e. 32 uncompressed bytes in a row. About 15% faster mszh_decomp on an Atom N270 for http://samples.mplayerhq.hu/V-codecs/mszh-zlib/avimzsh_sample.avi Originally committed as revision 19068 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	a7bfbe4e13	lcldec: ensure that the offset for av_memcpy_backptr is valid. Originally committed as revision 19067 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	bbf306742c	Fix memleak due to c->decomp_buf never being freed. Originally committed as revision 19064 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	908425c758	Only call inflateEnd when we were actually using the zlib code. Originally committed as revision 19063 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	4ad3df9da2	avctx->priv_data is initialized to 0, get rid of useless extra initialization. Originally committed as revision 19062 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	7ffc844742	Merge variable declaration and initialization. Originally committed as revision 19061 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	7c20421661	Use int-size types instead of char where it makes no difference. Originally committed as revision 19060 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	7a15b25827	Take advantage of available input padding to optimize mszh_decomp Originally committed as revision 19059 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	a5d2745d8e	Change maskbit variable to contain (1 << maskbit) Originally committed as revision 19058 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	e0b3af9059	Remove check that thanks to padding is no longer necessary. Originally committed as revision 19057 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	0b99764459	100l, the compression field in lcl extradata must be interpreted as int8_t, not uint8_t to allow -1 for "no compression". The original code worked, but only when char was signed. Originally committed as revision 19056 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	e4f141ad60	One more use for FFMIN. Originally committed as revision 19055 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	0d48e6ec7f	Pad the decompression buffer and use av_memcpy_backptr for the mszh decompression. Originally committed as revision 19054 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
