I have various video files in the webm format, this is also what google's Stadia service saves clips as, so when sharing webm videos with friends on telegram, they have to download the video as a file and then play it, rather than the more pleasant mp4 support where you can send it as a video instead of a file. It would be great if these video files could be shared directly in the app, as a videos, with in app streamed playback support.
