+Subject: [PATCH] avfilter/vf_libplacebo: remove deprecated field
+
+This has not been functional since a year ago, including in our current
+minimum dependency of libplacebo (v4.192.0). It also causes build errors
+against libplacebo v6, so it needs to be removed from the code. We can
+keep the option around for now, but it should also be removed soon.
