Camera not starting in the latest Jitsi Sdk 9.2.2 Android and iOS

[mdhanif-simformsolutions]

Description:

Unable to start camera in the latest sdk version 9.2.2 for Mobile (Android and iOS). I tried downgrading sdk version to 8.3.1 and it works.

Steps to reproduce:

1. Start meeting
2. When meeting is connected try enable disable camera it doesn't work

Expected behavior:

• Camera should be enable/disable as per user's input

Actual behavior:

Camera is off and it prints below error in log:-
Session 0: Exception while stopping repeating: android.hardware.camera2.CameraAccessException: CAMERA_ERROR (3): cancelRequest:630: Camera 1: Error clearing streaming request: Function not implemented (-38)

Server information:

• Jitsi Meet version: 9.2.2
• Operating System: Android Pixel 6A (Android 14)

It seems to be working in the latest Jitsi App on Playstore, but not sure what is wrong with our side of implementation.

[saghul]

Can you please share the full adb logcat ?

[mdhanif-simformsolutions]

yes sure this is how it looks :-

Just to mention again if I simply downgrade Version back to 8.3.1 It works perfectly fine on the same device.

[saghul]

Are you able to reproduce this with the sample app?

[mdhanif-simformsolutions]

No I am not, It works good in sample app

[mdhanif-simformsolutions]

It's not related to android though, I am having same issue in my iOS app with version number 9.2.2
Older version works well in iOS as well.

[saghul]

Are you connecting to your own server? What versions are you running there? The problem could be that.

[mdhanif-simformsolutions]

Hi, yes here are the version details :-

jicofo_1.0-1057-1
jitsi-meet-web_1.0.7658-1
jitsi-meet-prosody_1.0.7658-1
jitsi-meet-web-config_1.0.7658-1
jitsi-meet-turnserver_1.0.7658-1
jitsi-meet-tokens_1.0.7658-1
prosody_0.12.4-1
jitsi-videobridge2_2.3-61-g814bffd6-1

[saghul]

So that would be https://github.com/jitsi/jitsi-meet/releases/tag/stable%2Fjitsi-meet_9111 which is ~6 months old.

Can you please share your config.js ?

@jallamsetty1 Do you have any idea? The source name flags perhaps?

[jallamsetty1]

I am not sure what could be the issue either. Source names were enabled by default long time back. The only difference between the Nov'23 release and the latest stable is that we enabled backend support for AV1. However, this shouldn't affect client functionality if AV1 is not set as the preferred codec in config.js.

[mdhanif-simformsolutions]

Hello @saghul ,
I've attached our config for reference :-
config.js.zip

[saghul]

The config looks ok and has all the backwards compatibility flags there:

// Temporary backwards compatibility with old mobile clients.
config.flags = config.flags || {};
config.flags.sourceNameSignaling = true;
config.flags.sendMultipleVideoStreams = true;
config.flags.receiveMultipleVideoStreams = true;

I'm out of ideas here :-/

[mdhanif-simformsolutions]

Let me try downgrading few versions and check upto which version it works for me, from that maybe we can narrow down the issue

[mdhanif-simformsolutions]

@saghul So, I am able to use camera upto version 8.6.1
Starting from Version 9.0 I am facing issue while starting camera

[saghul]

Alright so something is weird. Reviewing the conversation here you say it works with the sample app.

So let's look at how you integrate the SDK into your app.

[mdhanif-simformsolutions]

Okay, So currently I am using version 8.3.1

and here's how we start meeting activity :-

val serverURL: URL = try {
            URL(jitsiServerUrl)
        } catch (e: MalformedURLException) {
            e.printStackTrace()
            return
        }

val jitsiMeetUserInfo =  JitsiMeetUserInfo(
                bundleOf(
                    "displayName" to "Test",
                    "email" to "test@yopmail.com"
                )
            )
val defaultOptions = JitsiMeetConferenceOptions.Builder()
            .setServerURL(serverURL)
            .setToken("addTokenHere")
            .build()
JitsiMeet.setDefaultConferenceOptions(defaultOptions)

val jitsiMeetConferenceOptions = JitsiMeetConferenceOptions.Builder()
            .setUserInfo(jitsiMeetUserInfo)
            .build()
JitsiMeetActivity.launch(this, jitsiMeetConferenceOptions)

Let me know if you need any other specific details

[saghul]

I don't see the room being set, is that intentional? Also, how does your server URL look like?

[mdhanif-simformsolutions]

I don't understand by what you mean room here ? do you have any example what do we set ?
Eg Server Url :- https://jitsi.com

Also I do set audio, video feature flags but I believe that will entirely remove Video button from my toolbar options.

[saghul]

In the conference options there is no call to seRoom. You need to specify which room to join.

Or did you miss that when copying the sample text over?

[mdhanif-simformsolutions]

Yes, I am sorry I missed that while copying sample text this is how it should look:-

val defaultOptions = JitsiMeetConferenceOptions.Builder()
            .setRoom("roomIdHere")
            .setServerURL(serverURL)
            .setToken("addTokenHere")
            .build()

[saghul]

Ok, that does look ok. Can you please upload the smallest app that doesn't work for you? I don't know what else to suggest TBH.

[mdhanif-simformsolutions]

Yes, I'll try to do that asap
