As someone still have troubles building PiOmxTextures, I prepared a little package that contains the binaries needed to make it run and have a look. In the past I tried[...]
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[...]
OpenGL is a good technology, and playing around with it on Android can be real fun! 🙂 By streaming a video to texture it is possible to create interesting effects,[...]
i.MX 6 is a good device. Qt runs pretty well on it. Also a plugin for hardware accelerated and zero-copy rendering seems to work pretty well. Simply building Qt for[...]
Again, video with animations: this time video is demuxed and decoded using the awesome VLC library. VLC is provided buffers from Java that are then drawn on a view. The[...]
For many uses, playing video while animations are running is pretty useful and it is also considerably stressful for the GPU. I therefore tested a couple of cheap chips with[...]
The new ports of Qt to mobile systems like Android, iOS and WinRT are getting more and more reliable. I just wanted to have a look at the current stage[...]
EDIT 02.25.2015: It seems to be missing even in Ubuntu 14.10. But probably the quickest way to install is: I was trying to develop an application that uses gstreamer 0.10[...]

I really don’t like FileMerge.app: I’ve always been feeling that Mac OS was missing a good tool like meld. Actually this turns out to be simply false: installing meld on[...]
Android’s logcat is really a brilliant tool for analysis and debugging. Unfortunately I really don’t like using it from Eclipse and using from the shell is not entirely comfortable, being[...]
I recently had some issues with iTunes and lost a few of the entries in the database. Maybe some little bug in iTunes, I don’t precisely know. Anyway, this led[...]
I don’t like to reinvent the wheel, and there are many logging codes out there, but still I couldn’t find what I wanted. Those were all either too complex or[...]
In the github project for PiOmxTextures I recently uploaded also a sample player (tools/POCPlayer) that can be used for debugging and testing the performance. This is supposed to be a[...]
Please take into consideration that this firmware is based on an old firmware and an old PiOmxTextures version. As I see still someone has troubles building PiOmxTextures, I built a[...]
There are some pretty common libraries that come very handy in some situations when developing for common embedded systems like Android and iOS. One of this is the ICU library,[...]
EDIT: This article is outdated. Refer to newer posts for properly working builds, instructions on how to build etc… In particular: “Using POT Builds” and “Build Procedure for PiOmxTextures“. EDIT:[...]
Ok, I did this a couple of months ago but I just realized it might be of help to someone who is currently using Necessitas Qt4 for some project and[...]
According to what I read around, it should be possible to install some build of Qt 5 using apt on Raspberry by adding the Qt repo: read here. However, some[...]
