Sorry but have you tried hosting your own video? There's only really one set of codecs that works across all devices. Video Player libraries that work really well with features like captions/subtitles, speed controls, automatic resolution shifting are hard to find, much less if you are not technical. If you want to cater to an audience outside the western world you'll want a video processing pipeline to downscale your videos to lower resolutions. Ideally you'd want to chunk up the video into something like HLS playlists so navigating around the video wouldn't require someone to wait until the download caught up to the middle of the file... the list goes on. Video is still hard. The big players make it seem easy, but it's not, in my experience, that simple.
