hevc : only write to max_ra and pocTid0 in the first slice.
3 avril 2017, par Ronald S. Bultjehevc : only write to max_ra and pocTid0 in the first slice.
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)

pthread_frame : call update_context_from_user() after acquiring lock.
3 avril 2017, par Ronald S. Bultjepthread_frame : call update_context_from_user() after acquiring lock.
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 :
