Michael Niedermayer	b3332a182f	avcodec/idctdsp: Transmit studio_profile to init instead of using AVCodecContext profile These 2 fields are not always the same, it is simpler to always use the same field for detecting studio profile Fixes: null pointer dereference Fixes: ffmpeg_crash_3.avi Found-by: Thuan Pham <thuanpv@comp.nus.edu.sg>, Marcel Böhme, Andrew Santosa and Alexandru RazvanCaciulescu with AFLSmart Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
Ronald S. Bultje	32baeafeee	jrev/xvid: hardcode use of C put/add_pixels_clamped. This removes the last use of the ff_put/add_pixels_clamped global function pointers, and as such they are removed. This patch has a negative effect on performance on MIPS, since there's a SIMD-optimized put/add_pixels_clamped, but no xvid or jrev. From a code maintenance point of view, that is probably acceptable. Because the global function pointers are removed, this fixes the following tsan warnings when running e.g. fate-dnxhr-parse: WARNING: ThreadSanitizer: data race (pid=29917) Write of size 8 at 0x0000025b12d8 by thread T2 (mutexes: write M1543): #0 ff_idctdsp_init src/libavcodec/idctdsp.c:313 (ffmpeg+0x00000044b68e) [..] Previous write of size 8 at 0x0000025b12d8 by thread T1 (mutexes: write M1541): #0 ff_idctdsp_init src/libavcodec/idctdsp.c:313 (ffmpeg+0x00000044b68e)	8 years ago

Diego Biurrun	95c0cec03a	idctdsp: Add global function pointers for {add\|put}_pixels_clamped functions These function pointers already existed in the ARM code. Adding them globally allows calls to the function pointers to access arch-optimized versions of the functions transparently.	10 years ago
