Subject: [FFmpeg-devel] [PATCH] avutil/hwcontext_d3d11va: prefer DXGI 1.1 factory when available
Date: Wed, 13 Mar 2024 20:13:41 +0100
Message-ID: <20240313191341.12479-1-timo@rothenpieler.org> (raw)
A lot of modern stuff straight up fails on the old 1.0 factory, which is
masked by the fact that it's only used when an explicit adapter is
specified.
