[Mesa-dev] [PATCH] st/vdpau: allow progressive video surface with interop

[Leo Liu]

mpv now interop with video surface instead of output surface previously,
so it fails with "vlVdpVideoSurfaceDMABuf", this's fine for Mesa GL, since
the code path will fall back to "vlVdpVideoSurfaceGallium", but this's
not the case for others
