Codec AVOption tune (Tune the encoding params (cf. x264 --fullhelp)) specified for output file #0 (fifo1.m2v) 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.
Codec AVOption preset (Set the encoding preset (cf. x264 --fullhelp)) specified for output file #0 (fifo1.m2v) 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.
