When writing Qt/QML applications, FontAwesome is frequently handy. Adding it to a Qt/QML app is not different from adding it to apps written with other technologies. You’ll need to download[...]
Many devices nowadays come with a notch at the top of the screen. You can clearly avoid drawing where cutouts are placed and ask the system to create a window[...]
I wrote an article about this topic in the past here. However, I had the chance to work more on the topic so this is a follow-up to that article:[...]
The old days of OpenMAX and omxplayer are now almost gone. Raspberry Pi has long moved to DRM/KMS and V4L2. Using omxplayer from Qt had the great benefit of reducing[...]
It has been some time since Qt 6 was released. Now that Qt 6.2 is almost out, I guess it is time to have a look at how Qt 6[...]
I frequently need to measure the frame rate in a Qt/QML application to have an idea of how heavy the changes I’m making are. In the past, I found two[...]
I frequently create classes that I use as an interface to settings in my apps. Using a single class with accessors makes the code readable, safer and simple to maintain.[...]
There are some utils that I use in most of my Qt projects. I’m a bit fed up of copy-pasting those every time I need something, so I created a[...]
Raspberry has a huge community that creates a considerable amount of material in a large number of projects. A relevant support for Yocto cannot therefore be missing for it. Months[...]
A few months back I decided to try to implement hardware decoding in WebKit. Unfortunately this task is always pretty long and complex for many reasons. I found the time[...]
A new version of Qt is out and some interesting changes are being developed. Interesting work was done on WebEngine. This package contains an experimental build of Qt 5.8.0-rc1 with[...]
This is an experimental version of POT that includes a few new features. The driver now includes an experimental version of playback of remote content including proper buffering of the[...]
This is a new build including a video probe to monitor frames being rendered. I also included a plugin to access video probe functionalities from QML. You can use it[...]
This is a follow-up to the image provided in this article. The concept is identical, but in this case this firmware is smaller, it is based on Raspbian Jessie Lite[...]
This is an image of Raspbian Jessie ready to test (and use) the Qt Multimedia Backend POT. This image is optimised for maximum performance (see the demos below). This is[...]
This is a build of version 5.1.0 for Raspbian Jessie of POT that includes Qt 5.5.1. As many asked in the past, this version also includes the QtWebKit module (WebKit1[...]
As some asked in the past, this is a Raspbian Wheezy image 05.05.2015 with fully working POT built for armv6 (which therefore works on both Pi 1 and Pi 2).[...]
This is a package containing binaries for PiOmxTextures 4.4.0. The relevant improvements here over 4.3.0 are: Fixed horizontal tearing effect. Fixed leaks when starting/stopping and restarting video. Added support for[...]
Many complained about an horizontal tearing issue when playing videos on the Pi using the PiOmxTextures driver. The issue was caused by a missing switch of buffers backing the textures[...]
As I see some are still working on the Pi, and someone asked to “port” to Qt 5.4.0, this is a small update to the Qt Multimedia Backend POC. This[...]
