[FFmpeg-devel] [PATCH v3 1/1] fftools/cmdutils: Print bit depths when executing 'ffmpeg -pix_fmts'

[Soft Works]

New output looks like this:

Pixel formats:
I.... = Supported Input  format for conversion
.O... = Supported Output format for conversion
..H.. = Hardware accelerated format
...P. = Paletted format
....B = Bitstream format
FLAGS NAME            NB_COMPONENTS BITS_PER_PIXEL BIT_DEPTHS
-----
IO... yuv420p                3             12      8-8-8
IO... yuyv422                3             16      8-8-8
IO... rgb24                  3             24      8-8-8
IO... bgr24                  3             24      8-8-8
IO... yuv422p                3             16      8-8-8
IO... yuv444p                3             24      8-8-8
