 I don't think this commit is related to this particular issue, iirc it
 fixes the case where a filter is specified on the command line and the
 filter does not support the input colour-space and does not support the
 optimal colour-space for the output stream (and instead of the optimal
 colour-space a colour-space supported by filter and encoder was chosen,
 typically gray), the "problem" here was reproducible before:
