Andreas Rheinhardt	8b395a5123	avcodec/mss1: Mark decoder as init-threadsafe Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
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.

James Almer	9ea6d2149e	avcodec/decode: add a flags parameter to ff_reget_buffer() Some decoders may not need a writable buffer in some specific cases, but only a reference to the existing buffer with updated frame properties instead, for the purpose of returning duplicate frames. For this, the FF_REGET_BUFFER_FLAG_READONLY flag is added, which will prevent potential allocations and buffer copies when they are not needed.

Diego Biurrun	1c5f264787	mss1: Add missing macro parameters to ARITH_GET_* macros It is wrong to pass no arguments to a macro that expects one argument and some compilers complain.	7 years ago

Lukasz Marek	331fae80a1	lavc/mss1: fix mem leak in case of init failure Signed-off-by: Lukasz Marek <lukasz.m.luki2@gmail.com>	10 years ago
Reimar Döffinger	cbeaf67888	Avoid using empty macro arguments. These are not supported by all compilers (gcc 2.95 but also older SPARC compilers, see gcc bug #33304 for example), and there is no real need for them. One use of this feature remains in libavdevice/v4l2.c which can't be replaced quite as easily. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	11 years ago
