@s710 said in How to revert to Android?:

Okay nevermind. Although the bootloader was already stating "DEVICE STATE - unlocked", and every reboot remindst of the bootloader being unlocked, I had to do fastboot flashing unlock_critical (which would ask again if I wanted to unlock the bootloader), and then the flashing tool for FF4 would run fine.

Android was successfully reinstalled.

Thanks for sharing! This post saved me quite some work.

@s710 Lol, it looks very good the pass, you have solved it with good ideas, you have done a great job, thank you very much

I think some notification text or popup stating that installing the just appeared update must be done in order to switch channels should be sufficient.

@s710 This may seem like a lot to me, but UT on the volla is quite power consuming indeed even though there seems to be a slight improvement since OTA-18. Maybe you can add a comment at the issue i opened here

Just to add to this. While I have not been able to actually process the QVideoFrame yet (meaning I have not been able to covert properly to QImage as all I have is a black image using the QVideoFrame::map or black image with some distortions using the alternate QOpenGLContext method outlined here - while it all says it is valid and not null 😢), I have discovered that in order to use the OpenGL Context one can create QWindow and use its surface like so:

https://github.com/qt/qtmultimedia/blob/5.12/src/plugins/avfoundation/mediaplayer/avfvideoframerenderer.mm#L123

Took me a while to figure out how to use it though as it didn't work for me and was crashing the app right on start when the code was part of a plugin (QObject). Unfortunately I was not able to Google it properly (didn't bump into anything that would say that usage is incorect), however with some luck and a lot of trial and error I found out it works when one creates this in the main.cpp file and then simply replies on the QOpenGLContext::currentContext().

And then considering QVideoFrame::map works on UT as part of the Camera QML object I would presume both methods need to work somehow :(. I am just obviously not doing something properly as it is failing for me as described above ^.

Got it, after googling even more. Some guy at the QT forum revealed:

Connections { target: Qt.application onAboutToQuit: { audioPlayer.stop() }

This works 🙂

@s710 Well our documentation is hosted here: https://github.com/ubports/docs.ubports.com - you can either clone the repo to your local disk, or make online changes. Then, after submitting the changes, open a pull request and we will review and merge it if ok.

@cibersheep Yeah well it is handled by the webview, after setting high dpi mode. This is also in line with the QT documentation so I guess everything is working correctly here.

Radio seems to be broken for searching and adding new stations and this, i don't know since when.

I added:

{ "policy_groups": ["location", "networking"], "policy_version": 16.04 }

And now the map works as expected. Thanks again.
