[FFmpeg-devel] [PATCH 1/3] avfilter/vf_libplacebo: switch to new background API

[Niklas Haas <ffmpeg@haasn.xyz>]

From: Niklas Haas <git@haasn.dev>

Fixes a deprecation warning, and also fixes a bug where the depredated
skip_target_clearing option was not correctly mapped to the new API inside
libplacebo upstream.
