When a Mastodon post has a video attached to it, I think Tokodon can play it if the user clicks on the video. However, for video uploads from Peertube accounts, only a link to the video page is shown which when clicked opens a browser window! Is it possible to show a Peertube video (just like a Mastodon video) instead of a link to the video page? There appears to be currently no working desktop client for following, commenting on and watching Peertube videos. There's Cuttlefish but it appears to be abandoned.
Yes it should be possible soon, maybe in time for the next major release. We're currently working on replacing the current media player with one that can support more media platforms via yt-dl, so more videos can be played inline inside of Tokodon :-)
