The following option is supported by the libdav1d wrapper.
@table @option
@item framethreads
Set amount of frame threads to use during decoding. The default value is 0 (autodetect).
@item tilethreads

@item filmgrain
Apply film grain to the decoded video if present in the bitstream. The default value
is true.
