Kinda bummed that Mastodon won't let you upload straight audio, so I decided to muck around with ffmpeg to make a still-image "video". Let's see how it looks:

ยท Web ยท 0 ยท 0

That worked pretty well. How it's done:
ffmpeg -i image.png -i tt-weasels.opus -acodec copy test.webm

I had already encoded the file with opusenc. If you provide a .wav, leave off the "-acodec copy" and ffmpeg will do the encoding for you.

Aww, bummer. I get a "Can't play this video" in Tusky. Android must not do VP8.
