[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Mon Sep 18 03:13:52 2023 +0200| [1046cfe347cec1121717eba3855142984da6a9db] | committer: Andreas Rheinhardt

avcodec/pthread_frame: Remove FF_API_SLICE_OFFSET

Since 432adca5fedcb277b9a715a723cfd40735ec58f8 no decoder
looks at the slice_count and slice_offset fields at all,
so there is no reason to synchronize them between the worker
and the user thread.
