I noticed that when browsing posts which contain a link to an MP4 file, Voyager very conveniently embeds the video in the post. This is an awesome feature and AFAIK, Liftoff and Voyager are the only Lemmy apps I've tested that do this.
Unfortunately, it doesn't seem to work well for IPFS links, even when including an .mp4 filename at the end of the URL. Doing this will allow the video to embed just fine on the Lemmy-UI web interface, but it won't carry over to the app interface.
I'm posting this as IPFS is a great option for decentralized video sharing online and it would be super nice to have it work just like any other MP4 url. I imagine it would be a simple fix, but I'm not too familiar with coding for applications, so someone else may have a better idea of what's going on under the hood that's preventing it from working. I've submitted this post with a link to an unrelated video for demonstration and testing purposes.
