Hi @rashidabbas,

Are you trying to play video that is copy protected? For security reasons, ReplayKit will not allow you to capture video that is protected by FairPlay DRM (the same video would also require HDCP to be transmitted over an HDMI connection).

We've listed this as a known issue in the example, since Apple and not Twilio controls what kind of content is allowed to be captured by ReplayKit.

Edit: I noticed that our known issue only mentions audio. Since the same copy protections concerns apply to video as well, I can update the entry to be more specific.

Best, Chris

Hi @rashidabbas,

Are you able to play videos in the YouTube iOS app? Is it just Safari where you're having the problem? Does it matter if the video is on youtube's website, or are all websites impacted?

Best, Chris

I am unable to share screen with any participant. Please guide me as I am broadcasting the screen perfectly using extension but I am stuck on how to view the broadcasting video in that room?????

Hi @hammas1993,

We don't have a dedicated "viewer" role in the ReplayKit example. You can use most of our other example apps to view the extension's broadcast (like the QuickStart app). The only thing to note is that these apps always connect with Tracks. If your Participant is just a passive viewer, you should ensure that you don't provide any Tracks in ConnectOptions.

Best, Chris

I suggest using: https://github.com/twilio/video-quickstart-ios/tree/master/VideoQuickStart

hammas1993 commented 5 years ago

when I start video Recording from sample handler.swift in Room "Test" the broadcasting starts. But when I attempt to join Room "Test" from VideoQuickStart broadcasting disconnects??? Why

You need a unique access token with a unique identity for each Participant.

@ceaglest except video in youtube app or any browser participants did not receive video with voice .participant receive blank screen

Hey @rashidabbas,

The YouTube app has a custom video playback pipeline and doesn't use copy protection for most of their video content. If you have content that is copy protected (e.x. a Netflix video stream) then it will not be possible to capture it using ReplayKit. If you are using AVPlayer, you can check the AVAsset.hasProtectedContent property to see if the content can be copied by ReplayKit.

Closing this issue since there has been no activity since 2019. Let us know if you have any more questions.

Thanks, Chris
