* Fix visual glitch with XvMC, caused by wrong idct permutation.Ivan Kalvachev2017-10-12
| | | | | | | | | | | | | | | In the past XvMC forced simple_idct since it was using FF_IDCT_PERM_NONE. However now we have SIMD variants of simple_idct that are using FF_IDCT_PERM_TRANSPOSE and if they are selected XvMC would get coefficients in the wrong order. The patch creates new FF_IDCT_NONE that is used only for this kind of hardware decoding and that fallbacks to the old C only simple idct.

* jrev/xvid: hardcode use of C put/add_pixels_clamped.Ronald S. Bultje2017-04-06
| | | | | | | | | | | | | | | | | | | 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)
