Michael Niedermayer	7f769ae41e	avcodec/rv30: fix switching back to the original resolution Fixes part of Ticket1388 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	def97856de	lavc: AV-prefix all codec capabilities Express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Lukasz Marek	4e9745fbff	lavc/rv30: fix mem leak in case of init failure Also replaced return -1 with return AVERROR(EINVAL) Signed-off-by: Lukasz Marek <lukasz.m.luki2@gmail.com>	10 years ago
wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago
Vittorio Giovara	6f6c029464	lavc: drop ff_pixfmt_list_420	11 years ago

Michael Niedermayer	be524ffc16	avcodec/rv30: put the rpr check back in init with the max vs bits bug fixed Its usefull to know immediatly if extradata is wrong and not just when later the decoder tries to use it. This check was removed by: `a6a2282c25` Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	d08c6e1101	avcodec/rv30: check rpr before use against maximum Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Anton Khirnov	a6a2282c25	rv30: fix extradata size check. It has been checking the number of bits in the offset instead of the actual offset. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago

Carl Eugen Hoyos	b86651a208	Check the return value of ff_rv34_decode_init() in rv30.c and rv40.c Avoids possible null pointer dereferences on oom. Fixes ticket #2727.	12 years ago
Martin Storsjö	9e0f14f16c	lavc: Make pointers to ff_cropTbl const There's no point in these pointers not being const. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Xi Wang	783e37f7ef	rv30: fix masking in rv30_loop_filter() The mask `x && (1 << y)' is incorrect and always yields true. The correct form should be `x & (1 << y)'. CC: libav-stable@libav.org Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Janne Grunau	9a2e79116d	golomb: use unsigned arithmetics in svq3_get_ue_golomb() This prevents undefined behaviour of signed left shift if the coded value is larger than 2^31. Large values are most likely invalid and caused errors or by feeding random. Validate every use of svq3_get_ue_golomb() and changed the place there the return value was compared with negative numbers. dirac.c was clean, fixed rv30 and svq3.	12 years ago
Michael Niedermayer	9f9307ff2a	rv30_decode_intra_types: make check tighter This makes no differnce as the affected values cannot occur But it will likely help static analyzers Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Janne Grunau	18d1d5886b	rv30: check block type validity Prevents crashes with the fuzzed samples from bugs 88, 89 and 125 after "golomb: avoid infinite loop on all-zero input".	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	e5985185d2	rv30: return AVERROR(EINVAL) instead of EINVAL On some platforms EINVAL could be positive, ensure we return negative values.	14 years ago
Michael Niedermayer	fc096e2e86	Revert "Do not decode RV30 files if the extradata is too small" This commit is plain wrong, theres no reason to error out at this point nor is the error value guranteed to be negative as it should be This reverts commit `289c60001f`.	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	ba87f0801d	Remove explicit filename from Doxygen @file commands.

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	42b7678d65	30l: when reading mb_offset in RV30 slice header its size should be calculated from current frame dimensions Originally committed as revision 16536 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	6751a00a3f	RV30 decoder passes possible frame sizes in extradata and selects an appropriate frame size from them in slice, make my decoder do that as well. This fixes issue 779 Originally committed as revision 16529 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
