Hi
Currently running H Indie 16.5.439 on Ubuntu 18.04.
One recurring issue I am having is the inability to export video 9MPEG-4) from Mplay , irregardless of what output settings or video dimensions I choose.

I always seem to get an error related to ffmpeg like the attached image.
First I see a warning

“Please use q:a or q:v, q:scale is ambiguous”
and then I get a NULL followed by
"Unable to find suitable output format for

Should I report this a bug, or is it more likely something wrong with my ffmpeg installation?
