Since Safari 12 accepts now VP8 codec, we decided to use VP8 codec for webrtc video chat.
We dropped H264 codec and decided to go for Vp8. This Vp8 codec works with all modern browsers:
For now, we only used H264 to support Safari.
Unfortunately H264 is very old codec and has some big drawbacks:
Vp8 has all qualities except.. it is not supported on Safari.
You can choose the codec selection form the config/webcam chatadmin panel
What about Microsoft Edge ?
Forget Edge compatibility for now, since Edge will be based on Chromium from early 2019 and thus will have vp8
Notice that we will add new vp9 soon that will increase quality of video. Of course Vp9 is not supported by safari.
Notice that soon, all majors browsers should adopt AV1, that will end the war between all these codecs.
