Values from subsequent values are guaranteed to be identical (since poc and nal_unit_type are checked to be the same between slices), so this doesn't affect output in any way, but does resolve the remaining reported race conditions (by tsan) in fate-hevc. In practice, this fixes tsan warnings like this: WARNING: ThreadSanitizer: data race (pid=25334) Read of size 4 at 0x7d9c0001adcc by main thread (mutexes: write M1386): #0 hevc_update_thread_context src/libavcodec/hevcdec.c:3310 (ffmpeg+0x000000b41c7c) [..] Previous write of size 4 at 0x7d9c0001adcc by thread T1 (mutexes: write M1383): #0 hls_slice_header src/libavcodec/hevcdec.c:596 (ffmpeg+0x000000b43a22)

Otherwise the thread may still be in the middle of decoding a previous frame, which would effectively trigger a race condition on any field concurrently read and written. In practice, this fixes tsan warnings like the following: WARNING: ThreadSanitizer: data race (pid=17380) Write of size 4 at 0x7d64000160fc by main thread: #0 update_context_from_user src/libavcodec/pthread_frame.c:335 (ffmpeg+0x000000dca515) [..] Previous read of size 4 at 0x7d64000160fc by thread T2 (mutexes: write M1821): #0 ff_thread_report_progress src/libavcodec/pthread_frame.c:565 (ffmpeg+0x000000dcb08a)

This is how the ref list manager links bitstream IDs to H264Picture/Ref objects, and is local to the producer thread. There is no need for the consumer thread to know the bitstream IDs of its references in their respective producer threads. In practice, this fixes tsan warnings when running fate-h264: WARNING: ThreadSanitizer: data race (pid=19295) Read of size 4 at 0x7dbc0000e614 by main thread (mutexes: write M1914): #0 ff_h264_ref_picture src/libavcodec/h264_picture.c:112 (ffmpeg+0x0000013b3709) [..] Previous write of size 4 at 0x7dbc0000e614 by thread T2 (mutexes: write M1917): #0 build_def_list src/libavcodec/h264_refs.c:91 (ffmpeg+0x0000013b46cf)
