There are 2 users in one twilio room. One is on chrome browser and another is on ios device's safari browser. Audio track is working for both users. But chrome is not showing safari's video track but safari is showing chrome's video track. And I am using both H264 and VP8

    Have you checked the information about Safari and H264 here? https://www.twilio.com/docs/video/developing-safari-11 – philnash May 03 '19 at 08:09
  • @philnash yes I checked that information. It works for safari on mac but it does not work for safari on ios. – Romil Mehta May 06 '19 at 04:34
  • Are you seeing any errors in the console? You can [connect to iOS Safari using desktop Safari](https://blog.idrsolutions.com/2015/02/remote-debugging-ios-safari-on-os-x-windows-and-linux/) to see what's going on. – philnash May 07 '19 at 14:18
  • @philnash There are no errors in the console. Only one warning which is on safari's console not on chrome's console. "This release of twilio-video.js includes experimental support for Safari 11 and newer. Support for safari is experimental because log.js:138" – Romil Mehta May 09 '19 at 04:38
  • Do you get the events for video published from the remote participant? Or is only the audio stream received? – philnash May 11 '19 at 19:30
  • @philnash On safari I got both video and audio events but on chrome I got only audio. – Romil Mehta May 17 '19 at 11:28
  • Oh, is the issue with Chrome on iOS? – philnash May 17 '19 at 18:32
  • @philnash No, this issue is with safari on iOS – Romil Mehta May 22 '19 at 04:56
  • But you said you're only getting audio in Chrome? – philnash May 22 '19 at 05:11
  • Yeah but I was using chrome on mac and safari on iOS. But I have fixed this issue. I was creating 2 LocalVideoTracks so after removing 2nd, chrome started showing safari's video track. – Romil Mehta May 22 '19 at 06:21
  • how did you solve this issue I am facing the same issue. – Deepak Singh Jan 15 '21 at 07:34

    @DeepakSingh My issue was because of 2 local video tracks. So, I deleted the second local video track and it fixed the issue. – Romil Mehta Jan 21 '21 at 06:45

This issue was because I was creating 2 local video tracks to display self preview. So after removing 2nd instance of localVideoTrack, it is working as expected.

i contacted the twilio support and they told me to change the room settings for Video Codec to VP8 -
(before i had chosen VP8 or h.264)

that solved it in our case.
