Subject: [FFmpeg-devel] [PATCH] lavfi/vf_libplacebo: test for renderable pixel formats
Date: Fri, 14 Jul 2023 12:47:53 +0200
Message-ID: <20230714104753.9847-1-ffmpeg@haasn.xyz> (raw)
From: Niklas Haas <git@haasn.dev>
Requires a new upstream function to test not for *import* support on a
given output pixel format, but also whether we can render to it.
Fixes: https://github.com/haasn/libplacebo/issues/173
