[idea] thumbnail for audio only "video"

[pirate486743186]

A possible alternative to the current audio only set up. (you keep the old way)

You launch the video player with the audio stream and the thumbnail as the video stream. This would work even for the cli version and behavior would be more consistent between video and audio.

the command: mpv audio.m4a --external-file=image.png --vid=1
