Prefer MPEG format?

[vanillajonathan]

I find it unclear what exactly the "Prefer MPEG format" switch does. What is "MPEG" format? Is that any MPEG format, or is that H.263, H.264 or H.265, is it MP4? If the toggle is disabled, what format is used instead of "MPEG"?

Why would I want this toggle off? Why would I want this toggle on? What are the advantages and disadvantages? How do I decide?

Maybe it could be rephrased, or have a subtitle, or have a tooltip or something that better explains it?

Why would I want this toggle on?

• Play the video on a device that doesn't support VP9
• GStreamer (e.g. Gnome Video) doesn't support subtitles embedded in WebM

Maybe the application could inform the user of this?

Consider adding a tooltip or a popover that explains this.
