If this is a number, then fallback will be triggered if N frames fail to decode in a row. 1 is equivalent to ``yes``. +``--vd-lavc-dr=<yes|no>`` + Enable direct rendering (default: no). If this is set to ``yes``, the + video will be decoded directly to GPU video memory (or staging buffers). + This can speed up video upload, and may help with large resolutions or + slow hardware.
