[MEncoder-users] MEncoder outputs "could not find matching colorspace"

[Cristian Manea]

I'm using XV video output, but that colorspace error occurs even if I don't
use yadif, or any other filters, and even if I use -vf scale and -vf
format=i420. Even more strange is that, if I do a search on google with
"could not find matching colorspace" and other keywords from that error
message, it returns only one matching result where a person is asking about
this on mencoder mailing list, and it receives the following response:

>* What does it means "Could not find matching colorspace - retrying with*
>* -vf scale..."? *

It means the device you are outputting to (the lavc encoder in this
case) requires a video format different than what your source material
is supplying.
