Codec AVOption vbr (Variable bit rate mode) specified for output file #0 (D:\Photography\demo_out_26
4_medium.mp4) 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 act
ually used for any stream.
