* vp8: make wait/thread_mb_pos atomic.Ronald S. Bultje2017-04-062-17/+18
| | | | | | | | | | | Fixes tsan warnings like this in fate-vp8-test-vector-007: WARNING: ThreadSanitizer: data race (pid=3590) Write of size 4 at 0x7d8c0000e07c by thread T2: #0 decode_mb_row_no_filter src/libavcodec/vp8.c:2330 (ffmpeg+0x000000ffb59e) [..] Previous write of size 4 at 0x7d8c0000e07c by thread T1: #0 decode_mb_row_no_filter src/libavcodec/vp8.c:2330 (ffmpeg+0x000000ffb59e)

* jrev/xvid: hardcode use of C put/add_pixels_clamped.Ronald S. Bultje2017-04-064-18/+14
| | | | | | | | | | | | | | | | | | | 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)
* x86/simple_idct: add explicit sse2 simple_idct_put/add versions.Ronald S. Bultje2017-04-063-14/+42
| | | | | | These use the mmx IDCT, but sse2 put/add_pixels_clamped implementations. This way we don't need to use the ff_put/add_pixels_clamped function pointers.
* cavs: add a sse2 idct implementation.Ronald S. Bultje2017-04-062-2/+61
| | | | | This makes using the function pointer ff_add_pixels_clamped() unnecessary, since we always know what the best implementation is at compile-time.
* cavs: convert idct from inline asm to yasm.Ronald S. Bultje2017-04-063-160/+171
|
* x86/xvididct: remove use of ff_put/add_pixels_clamped function pointer.Ronald S. Bultje2017-04-061-4/+4
| | | | | Since there's separate SSE2 implementations of xvid_idct_put/add, this patch has no practical impact on performance.
* idct_arm: remove use of ff_put/add_pixels_clamped function pointer.Ronald S. Bultje2017-04-061-4/+4
| | | | | | | Instead, hardcode the use of the _arm implementation of add_pixels, and use the C version for put_pixels (as no arm-optimized version exists). Since there's separate implementations of idct{,_put,_add} for neon, this has no practical impact on performance.
* pthread_frame: allow per-field ThreadFrame owners.Ronald S. Bultje2017-04-064-15/+20
| | | | | | | | | | | | | | | | | | | This tries to handle cases where separate invocations of decode_frame() (each running in separate threads) write to respective fields in the same AVFrame->data[]. Having per-field owners makes interaction between readers (the referencing thread) and writers (the decoding thread) slightly more optimal if both accesses are field-based, since they will use the respective producer's thread objects (mutex/cond) instead of sharing the thread objects of the first field's producer. In practice, this fixes the following tsan-warning in fate-h264: WARNING: ThreadSanitizer: data race (pid=21615) Read of size 4 at 0x7d640000d9fc by thread T2 (mutexes: write M1006): #0 ff_thread_report_progress pthread_frame.c:569 (ffmpeg:x86_64+0x100f7cf54) [..] Previous write of size 4 at 0x7d640000d9fc by main thread (mutexes: write M1004): #0 update_context_from_user pthread_frame.c:335 (ffmpeg:x86_64+0x100f81abb)

* codec: bitpacked: add decoderDamien Riegel2017-04-056-1/+164
| | | | | | | | | | | Add a codec capable of decoding some formats of the RFC4175. For now it's only capable of handling YCbCr-4:2:2 with 8-bit or 10-bit depth. For 8-bit it's a simple pass-through, for 10-bit it depacks the stream in the AV_PIX_FMT_YUV422P10 pixel format.
