QWebEngine Install on Raspbian (Debian 10) Raspberry Pi 3 B+

evelikov92

Hi Everyone. That is my first post.

I need to create one application which will run videos on the Raspberry Pi. When I try used QMediaPlayer then I run the videos the lack is terrible. When I run top command I see more of 100% of the CPU only for my process. Which is disaster.
I also try with omxplayer. Is working but is not give me the functionality what I want. For example is not possible to stop the video and start again. I will use touch screen without keyboard.

For that I decide to try with Create simple web page with only video tag and with simple javascript to manage start and stop of the video.
But when I try to used it I see I don't have QWebEngine.

I'm not make qt from source I just install libraries. But now I cannot found QWebEngine.
What I install on raspbian is:

sudo apt-get install pulseaudio
sudo apt-get install cmake
sudo apt-get install libvlccore-dev
sudo apt-get install libvlc-dev
sudo apt-get install qttools5-dev-tools
sudo apt-get isntall qtdeclarative5-dev
sudo apt-get install qtbase5-dev
sudo apt-get install qtmultimedia5-dev
sudo apt-get install qt5-qmake
sudo apt-get install qt5-default
sudo apt-get install qtmultimedia5-doc
sudo apt-get install qtmultimedia5-doc-html
sudo apt-get install qtmultimedia5-examples
sudo apt-get install qml-module-qtquick-controls

What library I need to install for can use QWebEngine.

I think I understand, but not sure

@evelikov92 Did you activate "universe" repository on your RaspberryPi?

evelikov92

@jsulm said in QWebEngine Install on Raspbian (Debian 10) Raspberry Pi 3 B+:

"universe" repository on your RaspberryPi

I think NO. Is fresh installation.
How can I activate it?

jsulm

@evelikov92 Activate it, on Ubuntu many Qt webengine packages are in Universe

evelikov92

@jsulm

root@raspberrypi:/home/pi# add-apt-repository universe
Traceback (most recent call last):

jsulm

@evelikov92 Edit /etc/apt/sources.list

evelikov92

@jsulm

What thing to add on the file?

jsulm

@evelikov92 Look for something like

deb http://de.archive.ubuntu.com/ubuntu/ bionic-backports main restricted universe multiverse

Make sure universe is there

evelikov92

I will leave it.
I will install QT from the source. Maybe it will be faster.
If is again not work then I will make the project in another way.

jsulm

@evelikov92 No! Don't add the line I posted to your /etc/apt/sources.list !
It was just an example for how it looks.
Search for a similar line in your /etc/apt/sources.list and make sure universe is there.

evelikov92

@jsulm Now I try to build from the source
