I have wrapped Jitsi in a small app using Sailfish Webview: nephros/Gam - Gam - Codeberg.org
The app is not finished, but does show the problem.

This is the WebViewPage: Gam/JitsiPage.qml at master - Gam - Codeberg.org

I can confirm. I had the same phenomenon using a video calling on hydrogen.

XA2 here, can’t use camera.
On jit.si: “Can’t start the camera for an unknown reason” :frowning:

#4

The “blue tint effect” is only active when front cam is used.

If I’m switching to rear cam this effect is gone. Switching back to front cam will activate the effect again.

I’m on X10III…

Yes using the browser I see that too. But that’s a different thing.
Anyway, that s the output from EMBED_CONSOLE when that happens:

Looks okay, maybe Camera 0 is wrong?

Can anyone confirm this is also in 4.5? Don’t have access to one of my 4.5 devices right now.

#7

This test also fails with the browser:

https://mozilla.github.io/webrtc-landing/gum_test.html

#8

Except for the video preview (which is blueish on my side too), does anyone have success to actually video encode the stream? I mean, seeing it on another device.
I have like 1s of stream then it locks up. It may be specific to my adaptation though.

Thanks for raising the bug and sorry for hijacking with a by-question.

Blue tint also happen with both cams on xz2 compact port

#10

On the volla/GS290 with 4.4.0.72 and on volla22/GS5 4.5.0.16 using the browser there is NO tint. I tested with talky.io and meet.jit.si servers. Hmmm. Hardware compositor thing?

Can confirm with a 10 III, using 4.5.0.18.

  1. Browser with jitsi = blue
  2. Browser with Google Meet = blue
  3. Vivaldi with Jitsi = not blue

Just updated the GS5 to 4.5.0.18 and it’s also fine. So it’s lower level. EDIT: fine in the browser, that is.

Xperia 10 Dual-SIM: 4.5.0.18: NOT affected.
