[FFmpeg-devel] [PATCH] Extend show_pix_fmts() to make it print the input/output support

[Stefano Sabatini]

Hi, as in subject.

Resulting output looks like:
name       nb_channels depth is_alpha input  output
yuv420p         3         8      n      y       y
yuyv422         1         8      n      y       y

bgr24           3         8      n      y       y
yuv422p         3         8      n      y       y
yuv444p         3         8      n      y       y
yuv410p         3         8      n      y       y
yuv411p         3         8      n      y       y

bgr8            1         8      n      y       y
bgr4            1         4      n      n       y
bgr4_byte       1         8      n      y       y
rgb8            1         8      n      y       y
rgb4            1         4      n      n       y
rgb4_byte       1         8      n      y       y
nv12            2         8      n      y       y
...

This can be parsed to get the list of input/output format with
something of the kind:

in_pix_fmts=
$(ffplay -pix_fmts | egrep '[[:alnum:]_]+ +[[:digit:]] +[[:digit:]]+ +[yn] +[y]+ +[yn]' | cut -f1 -d" ")

out_pix_fmts=
$(ffplay -pix_fmts | egrep '[[:alnum:]_]+ +[[:digit:]] +[[:digit:]]+ +[yn] +[yn]+ +[y]' | cut -f1 -d" ")

BTW also better would be to have somthing of the type:
IOA argb            4         8
