Ronald S. Bultje	2e664b9c1e	pthread_frame: make accesses to debug field be protected by owner lock. The av_log() is done outside the lock, but this way the accesses to the field (reads and writes) are always protected by a mutex. The av_log() is not run inside the lock context because it may involve user callbacks and doing that in performance-sensitive code is probably not a good idea. This should fix occasional tsan warnings when running fate-h264, like: WARNING: ThreadSanitizer: data race (pid=10916) Write of size 4 at 0x7d64000174fc by main thread (mutexes: write M2313): #0 update_context_from_user src/libavcodec/pthread_frame.c:335 (ffmpeg+0x000000df7b06) [..] Previous read of size 4 at 0x7d64000174fc by thread T1 (mutexes: write M2311): #0 ff_thread_await_progress src/libavcodec/pthread_frame.c:592 (ffmpeg+0x000000df8b3e)	8 years ago
Ronald S. Bultje	7f05c5cea0	h264: don't re-call ff_h264_direct_ref_list_init() w/ frame-mt.
