Hi Massimo,

br,
Jani

Hi devs,
I'd like to gather some help to complete the resolution of https://bugreports.qt.io/browse/QTBUG-51064 in time for 5.11.3 and 5.12.0.
I did my best and fixed video playback on Linux and Windows, however on macOS it's still broken (surprise!)
I already spent some hours to figure out why, but my limited knowledge of OGL didn't get me that far.
So, the 5.11.3 QtMultimedia changelog is partially incorrect, because of macOS.

TL;DR Before my patch it was impossible to play videos in QML in a OGL core context application.

I'd like to point out how badly this issue has been handled. It's been reported on February 2016 and marked as P4.
To me, it seems a nonsense to ignore issues like this, especially now that Qt3D offers a lot of possibilities and sooner or later you might need to switch your app to core profile.

I think some macOS + OGL expert might take a couple of hours to fix it, so it'd be much appreciated if someone can contribute to this.

Also I'd like to ask if there is already an ETA for 5.11.3, to understand if there actually is time or not.

Thanks in advance !

Hi,

The linked change has been merged to 5.11 and is part of upcoming Qt 5.11.3 release. Qt 5.11.3 and Qt 5.12.0 content is already frozen and releases coming out soon, so any further improvements should go to 5.12 branch. Items merged to 5.12 now will be included in Qt 5.12.1 planned for mid-January.

Similarly as with Qt 5.9 LTS, there will be frequent patch releases of Qt 5.12 LTS. So as soon as a fix is merged to 5.12 branch, it won’t take very long before it is part of a Qt 5.12.x patch release

Yours,

Tuukka

I'm not trying to justify it not being fixed, but just wanted to be a bit pedantic and point out that the reporter actually set the priority, not a Qt dev.
