Jitsi-meet: Camera only works the first time on iOS safari. (Alpha release)

[muditjuneja]

I am trying to connect to a meeting from iOS safari browser. It works fine the first time I start the camera. But if I switch it off and then try turning it on again, it doesn't start.

On browser console I can see the following warning :
2020-05-29T04:16:11.316Z [modules/RTC/RTCUtils.js] Failed to get access to local media. Error: Invalid constraint [object Object]

And the following error :
[native code]:1 2020-05-29T04:16:11.320Z [features/base/tracks] set track unmute failed s {gum: Object, name: "gum.general", message: "Invalid constraint", stack: "s@https://alpha.jitsi.net/libs/lib-jitsi-meet.min.…s?v=4163:1:92377↵promiseReactionJob@[native code]", constructor: function}

I am using the alpha version to test this because the current stable version doesn't even start the camera not even the first time.

Can anyone help? Is it the web thing or something related to the video bridge?

Steps to reproduce:

1. Open the web version of alpha.jitsi.net on iOS safari.
2. Grant access to camera
3. Open the camera by clicking the camera icon: It will open up your camera
4. Stop the camera by clicking again on the same button
5. Then click on the button to start again : Camera won't start and it will give the above error in the browser console.

Client information:

• Browser / app version: Safari/ Safari 12
• Operating System: iOS

Expected behavior:

The camera should start again after clicking the button.

Updated the description of the ticket.

Can you pls add more details about the device and the iOS version that is running on this specific device ? Also, can you please elaborate on what you mean by "opening the camera by clicking on camera icon" ? Are you referring to the camera icon on the browser tab or the camera button on the bottom ?

I am using ios safari version 12 on iphone >=8. I am talking about the camera tool icon on the jitsi web which is used to switch the camera state.

@jallamsetty1 Hello! Note that alpha.jitsi.net isn't usable on any iOS or iPhone version (eg. camera starts off/freezes, local user video is a frozen image, "Enter your name" button is off the screen, etc).

There are a few iOS issues floating around here referencing different bugs, but I get the impression that the team might think the latest Jitsi works on iOS? If iOS is still a work-in-progress, then this issue be disregarded. But if not, then there are probably a bunch of redundant issues about to appear when the latest release goes live on meet.jit.si.

Hey there, we are aware of the issue with Safari and alpha.jitsi.net. This has something to do with Safari and callstats integration which we are trying to resolve but please be assured that these issues won't appear when the latest release goes live on meet.jit.si since callstats integration is disabled there. If you wan't to try the latest fixes, please try out beta.meet.jit.si.

Can you please try against https://beta.meet.jit.si and see if you can reproduce the issue ? If so, can you please provide the full console log ?

[nathankurtyka]

@jallamsetty1 Thank you for the reply! beta.meet has the same problems.

I'm happy to pull console logs, but I believe the iOS problems are a tad broader than miscellaneous JS or connection errors. For example, loading any room on iOS (on the beta site) displays the local video in some Apple media player completely on top of Safari (Jitsi isn't even visible any longer).

Does this genuinely work for anyone else on iOS? Maybe I'm crazy, but I can't fathom anybody can complete a meeting on iOS at the moment.

Which branches are pointing to beta.meet.ji.si. I would like to build the entire beta stack myself. Guide me!

@jallamsetty1 Maybe we need those CSS classes to hide the inline media controls?

    video::-webkit-media-controls-overlay-play-button {
      display: none;
    }

And maybe some more...

You can use the nightly builds from https://download.jitsi.org/unstable/ to build your own deployment with all these fixes.
If your issue is fixed, can you please close this issue ?

Yeah, I can give those a try but we also have "playsinline" atrribute set to true on the video element so theoretically the preview should not start in full screen mode on iOS 10 and newer versions. I will try to hide the media controls, thanks for the suggestion @saghul.

@nathankurtyka, you can exit full screen with a pinch gesture and the preview will continue to play inline and you should be able to continue with the conference.

[jallamsetty1]

@nathankurtyka, I have committed a fix for the local video starting in full screen. This should be available in nightly soon.
@muditjuneja, I will be closing this issue since your issue seems to be fixed.

[nathankurtyka]

@jallamsetty1 - I can't even imagine how tricky it must have been to bring this feature to life.. great job!

[muditjuneja]

@jallamsetty1 I don't think it is related to the fix that you pushed. Why are you closing this?

[l3d00m]

Could you try out the newest version and see if it is fixed? Otherwise feel free to reopen the issue.
