ffmenc takes the string from AVStream.recommended_encoder_configuration
and stores it, ffmdec reads it back into
AVStream.recommended_encoder_configuration

It is just needed to make sure codecpar matches this, which would be
easier if AVOptions would work with codecpar as then it could be
directly set from the string description.
