Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

Carl Eugen Hoyos	1e34014010	lavc/bmp: Avoid a heap buffer overwrite for 1bpp input. Found by Mingi Cho, Seoyoung Kim, and Taekyoung Kwon of the Information Security Lab, Yonsei University.	6 years ago
Michael Niedermayer	63b8d4146d	avcodec/bmp: Use ff_set_dimensions() Fixes out of memory Fixes: 1282/clusterfuzz-testcase-minimized-5400131681648640 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago

Michael Niedermayer	0c42d0add3	avcodec/bmp: Fix runtime error: negation of -2147483648 cannot be represented in type 'int'; cast to an unsigned type to negate this value to itself There is code checking height and width later, leaving an invalid value invalid is thus fine.

Vittorio Giovara	3496cec433	msrle: Use AVFrame instead of AVPicture Callers always use a frame and cast it to AVPicture, change ff_msrle_decode() to accept an AVFrame directly instead. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Michael Niedermayer	aec340c533	avcodec/bmp: Analyze BGRA files alpha channel to choose pixel format BGRA BMPs commonly do contain an all transparent alpha channel 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
Reimar Döffinger	d96090e7b6	Support BMP files that do not properly align lines. Quite a few programs missed that detail of the spec (including old versions of FFmpeg I believe) and when we would otherwise fail anyway it seems worth a try to use a simple byte-aligned stride instead. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
