Codec AVOption crf (Select the quality for constant quality mode)
specified for output file #0 (http://localhost:8090/feed1.ffm) has not
been used for any stream. The most likely reason is either wrong type
(e.g. a video option with no video streams) or that it is a private option
of some encoder which was not actually used for any stream.
