[FFmpeg-devel] [PATCH 17/57] avcodec/mpegvideo, mpegpicture: Add buffer pool
Andreas Rheinhardt
andreas.rheinhardt at outlook.com
Tue Apr 30 00:13:58 EEST 2024
This avoids constant allocations+frees and will also allow
to simply switch to the RefStruct API, thereby avoiding
the overhead of the AVBuffer API.
It also simplifies the code, because it removes the "needs_realloc"
field: It was added in 435c0b87d28b48dc2e0360adc404a0e2d66d16a0,
before the introduction of the AVBuffer API: given that these buffers
may be used by different threads, they were not freed immediately
and instead were marked as being freed later by setting needs_realloc.
