Large images are broken apparently.

If you send a large image (phone picture) the webm you get can't be played in discord's client.

Potential fix 1:
Limit the output dimensions of ffmpeg by scaling.

can be done with scale filter -vf "scale='min(600,iw)':-1" added to ffmpeg command (on input maybe?).

Potential fix 2:
Use discord's cdn to resize the image via url arguments. Prepend ?width=960&height=720 to URL potentially.
This will require us to know the image aspect ratio/dimensions beforehand (does discord api provide this in message attachments?)
