Subject: [FFmpeg-devel] [PATCH] lavfi: make job count configurable separately from thread count
Date: Tue, 20 Sep 2022 12:50:14 -0500
Message-ID: <20220920175021.60790-1-rcombs@rcombs.me> (raw)
Slicing frames into a larger number of jobs can improve performance significantly on asymmetric-multiprocessing systems.
On my M1 Max, performance on the two filters transitioned to the new model in this patchset (vf_scale and vf_unsharp, chosen somewhat arbitrarily as reasonable test cases) improved by roughly 15%.
