Huge delay in rendering remote video very first frame. @manjeshbhargav

Looks like a global issue. It's happening in almost all the platforms.

Hi @rishab1065 , @Balasnest ,

Thanks for writing in with your issues. Can you share some Room SIDs so we can start investigating?

Hi,
I'm using twilio-video.js 2.10.0 and @types/twilio-video 2.7.1.

Experiencing a similar issue. When receiving remote video track subscribe (video is ok here) -> unsubscribe -> subscribe , after the last subscribe the user gets a black screen in the remoteVideoTrack.

Last year this works fine in our website.

iOS 13

Hi @manjeshbhargav ,

@apostololeg and I are still facing the same issue.

• We have managed to fix the issue with iOS13 thanks to browsers' autoplay policy
• The workaround does NOT work for prior iOS version (iOS 11 and 12 and potentially earlier versions)
  Any hint?

@rishab1065 , @izabelavmelo , have you managed to solve this issue?

Software version:

• Browser(s): Safari
• Operating System: iOS 11 and 12 (and potentially previous versions)
• twilio-video.js: 2.12.0
• Third-party libraries: JavaScript, React and Angular

Thanks,
Florent

Hi, @Flo-Mercaux !
I fixed with this issue: https://github.com/twilio/twilio-video.js/issues/558#issuecomment-467981412

I removed the stop() and it works for me:

But I faced this bug on all devices (not only iOS). So, I think it's not the same as you. :disappointed:
