1735203 - [Bug]: No video can be played during a phone call on Adreno 618 device

Status: RESOLVED INVALID

(Core :: Graphics: WebRender, defect)

Description

[Kevin Brosnan [Ex-Mozilla]]

From github: https://github.com/mozilla-mobile/fenix/issues/21681.

Steps to reproduce

1. Start a phone call
2. Open some webpage with videos, like youtube.com
3. Try to play a video
4. You can observe, that the video playback does not start !!!

This is a HUGE disappointment, because this used to work in previous Firefox versions!
So I am rolling back to my previous Firefox version, until this has been fixed!

Many thanks for taking care about this very annoying bug with high priority!

Expected behaviour

The video playback starts

Actual behaviour

No video playback starts. Eventually, half a second is being played and then the video stops immediately!

I think it's incredibly unlikely this is a graphics -- or even gecko -- bug. I can reproduce 100% in Fenix on a range of devices, but I cannot reproduce in geckoview_example, or even android-components' samples-browser. I'm going to close this as invalid and I'll leave a comment on the Fenix github issue.

My brief investigation showed that MediaSession.pause() is continually getting called, and I could also see mentions of AudioFocus in the logcat. Which points me to here as a first guess: https://searchfox.org/mozilla-mobile/rev/ec8d108e4475517178d2edd0ca3e64530cb13286/android-components/components/feature/media/src/main/java/mozilla/components/feature/media/focus/AudioFocus.kt#63
