I have been trying to get ffv1_vulkan to encode since it was first added. My machine is running Arch Linux, a 7800XT using Mesa drivers and at time of testing/writing "ffmpeg version N-118193-g5f38c82536" Currently when running a basic encode I get a hand full of errors: `ffmpeg -hwaccel vulkan -hwaccel_output_format vulkan -i x264-video.mp4 -c:v ffv1_vulkan test.avi` I get this output: ``` [ffv1_vulkan @ 0x5c6e5c559a80] format nv12 not supported [vost#0:0/ffv1_vulkan @ 0x5c6e5c5ca700] [enc:ffv1_vulkan @ 0x5c6e5c5565c0] Error while opening encoder - maybe incorrect parameters such as bit_rate, rate, width or height.
