list colorspaces supported for each codec in ffmpeg?

[marcorocchini]

Ho can I achieve a list of all supported colorspaces format for each codec supported in ffmpeg?

e.g.: flv support 4:2:2 or 4:4:4?

thanks

iirc flv (Flash Video) only 4:1:0 and 4:2:0

Only way I know of figuring out (without trying and reading the debug output) which codec supports which color samplings would be to look into the source code. There is no option in ffmpeg which will tell it to output which codec supports which color samplings.
