[FFmpeg-devel] [PATCH 32/38] avfilter/vf_grayworld: Remove empty options and AVClass

[Andreas Rheinhardt]

This filter only had an AVClass and empty options because up until
recently, avfilter_init_str() errored out when options were provided
for a filter without an AVClass. But setting (generic) options is
necessary to take advantage of timeline support. So with
avfilter_init_str() fixed, the AVClass and the options can be removed.
