This is the development list, not the user support list. However, I can tell
you that ffmpeg currently does not support this codec as far as I am aware,
as you can verify yourself with `ffmpeg -codecs | grep -i grass`. I do however
suspect that it is not a very original codec and may in fact simply be a
variation of something else, so a sample file would be able to confirm this.

For what it's worth, I suspect that any reasonably modern codec with a good
encoder will outclass this "HQ codec" in efficiency by orders of magnitude.
