[Xperia XA2][4.5.0.19] SFOS Browser doesn't get access to camera

REPRODUCIBILITY: 100% OS VERSION: 4.5.0.19 HARDWARE: Xperia XA2 - Dual SIM h4113 UI LANGUAGE: en_GB REGRESSION: Probably, additional info DESCRIPTION: When joining Jitsi Meet (at framatalk.org, teamjoin.de) or eduMEET (at lets.teamjoin.de), neither service gets to use the phone’s camera.

as the browser does get access to the camera (same OS version, different device).

Jitsi Meet used to have problems with Firefox, more so with hardened Firefox. Some research is in order, esp. considering SFOS’ Firefox version is not the newest.

I remember ~a year ago I just used ungoogled chromium on my desktop (closest equivalent on SFOS/Android: Bromite) and the Jitsi-Meet Android app on my SFOS phone. The latter worked really well.

Some research is in order

I’d assume that when the browser crashes is when the problem enters developer territory. What research would you suggest for an end user?

[smatkovi]

Maybe then angelfish from chum is working? I think that’s based on chrome or chromium

[ohnonot]

No I meant on Jitsi’s side. "jitsi-meet firefox problems " etc.

[ric9k]

Unfortunately, the lovely Angelfish stops here:

On my XA2, I can neither use jitsi in the stock browser. No way to enable the camera.

[jojomen]

Ok, that’s a possible avenue of investigation, which also in developer land. However, a bad web page should not bring the browser to a crash, so there is something to be changed on the SFOS side as well

[thigg]

For audio only i find the browser still more reliable than the jitsi meet app. Those crashes during conferences are really annoying…

btw i think most jitsi problems with firefox are fixed now, at least i didnt have problems for a long time

[ohnonot]

@jojomen

which also in developer land.

I think you should stop making this distinction, it’s not real, you only keep yourself from finding solutions.

BTW, if I remembered I’d have told you already, I also looked through my browser history.

Yes!!! I had the same warning and found no way to confirm or allow.

Can it be that the website wanted nasty things from the browser, that the browser legitimately denied and therefore stucks?

[attah]

So what does it say when it crashes?

If i provoke a crash on YouTube, while running the browser from terminal, i get this:

postPendingRepliesAndDeferredMessages: mReplyID == null, from kWhatError:STOPPING following kWhatError:STOPPING
Redirecting call to abort() to mozalloc_abort

Segmentation fault

[ric9k]

In my case, AngelFish doesn’t crash. It just ends at the page shown above and offer no way to allow camera use.
Regarding the stock browser, on my XA2 Single 4.5.0.19, the browser does not crash nor freeze.
I goes to the conference with disabled camera and has no reaction when I try to enable the camera by pressing the the strike-through camera button.
