Question

Mobile development

Comparing video format support on specified platforms and browsers

I saw that they all support H.264. And it seems that there is no need to re-encode the video. But what other potentially gluttonous problems might arise? For example, with how WebRTC will work.
Also, these browsers and platforms support older MPEG-4, it has a lower compression ratio (in the sense of saving traffic), but it is also supported by IE9-IE11 and Safari. You need to choose one of these formats.
I also need to find out how important the quality of communication is for WebRTC to work.
