SpacemiT K1's BSP has a version of FFmpeg that contains both v4l2m2m and their own *_stcodec decoders. Not only is their V4L2 driver for their mvx decoder seemingly totally broken (output buffers are all zeros), but it doesn't have any of the DRM_PRIME support work that is maintained out of tree. The result is we use a broken copyback decoder instead of a (mostly) working zero-copy decoder because we didn't include any logic to rank non-hwaccel decoders by pixfmt like we have with device type for hwaccel decoders.
