* master: (172 commits) Check mmap() return against correct value Signed-off-by: Michael Niedermayer <michaelni@gmx.at> vorbisdec: Employ proper printf format specifiers for uint_fast32_t. Support fourcc MMJP. Support fourcc XVIX. Support fourcc M263. Support fourcc auv2. Fix indentation. Support PARSER_FLAG_COMPLETE_FRAMES for h261 and h263 parsers. ffplay: avoid SIGFPE exception in SDL_DisplayYUVOverlay avi: try to synchronize the points in time of the starts of streams after seeking. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Add flag to force demuxers to sort more strictly by dts. This enables non interleaved AVI mode for example. Players that are picky on strict interleaving can set this. Patches to only switch to non intereaved AVI mode when the index is not strictly correctly interleaved are welcome. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> applehttp: Don't export variant_bitrate if it isn't known crypto: Use av_freep instead of av_free CrystalHD: Add AVOption to configure hardware downscaling. Check for malloc failures in fraps decoder. Use av_fast_malloc instead of av_realloc in fraps decoder. general.texi: document libcelt decoder. Fix some passing argument from incompatible pointer type warnings. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> configure: Add missing libm library dependencies to .pc files. oggdec: reindent after 8f3eebd6 ... Conflicts: libavcodec/version.h Merged-by: Michael Niedermayer <michaelni@gmx.at>
