 Following the current [https://ffmpeg.org/ffmpeg-filters.html#allrgb_002c-
 allyuv_002c-color_002c-colorspectrum_002c-haldclutsrc_002c-nullsrc_002c-
 pal75bars_002c-pal100bars_002c-rgbtestsrc_002c-smptebars_002c-
 smptehdbars_002c-testsrc_002c-testsrc2_002c-yuvtestsrc documentation]
 there seems to be no option to define pixel format for `color` or
 `nullsrc` filters.

 I often find myself defining `fomrat=argb` (or another) following right
 after `color...` filter.

 Correct me if I am wrong, but my thinking is that having pixel format
 defined right on the source (`color` or `nullsrc`) could avoid conversion,
 hence increase the overal performance.

 It seems `testsrc2` has `format` option available, so maybe similiar
 solution  can be provided for the `color`, `nullsrc` or other.
