Ronald rejected the previous version because of the obscure error
messages. I suggested an alternative and Michael sent a new patch
If this is also not ok then please say so. That way the error messages
can be removed before pushing the patch and we can go back to focus on
things worth discussing.

I agree about removing the encoder, but the decoder is needed for
existing streams. Unless everyone just argues it has no real world
samples for being an avcodec-only toy codec.
If you send a patch removing the encoder without also trying to remove
all the things that currently depend on it (One or two filters i think)
then I'll +1 it. ffv1 and mpeg4 encoders are enough for any kind of
testing, fate or otherwise, that might require a native encoder.
