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).[...]
As someone asked, I tried to port POT to the recently released Raspbian Jessie. Everything works pretty much the same, except for a few changes. Unfortunately I needed to rebuild[...]
This package includes mostly bug fixes over beta2. You can consider it stable in the sense that no one complained about severe bugs for a few days. You always have[...]
A few weeks ago I came across the interesting task of adding deinterlacing to the POT rendering pipeline.I had never looked into deinterlacing with POT, but the code was actually[...]
This package includes mostly bug fixes and some slight improvements over beta 1. Please fil bugs to github if needed. Refer to previous articles on how to use. Download PiOmxTextures[...]
These are two packages containing binaries for PiOmxTextures (POT) for Raspberry Pi 1 and 2 running Raspbian. The main changes are: Completely changed approach to GPU buffer and structure allocations.[...]
These are two packages containing binaries for PiOmxTextures (POT) for Raspberry Pi 1 and 2 running Raspbian. PiOmxTextures 4.5.0 The first package contains POT 4.5.0 for Raspberry Pi (1): Improved[...]
Someone asked if PiOmxTextures (library and Qt OpenMAX-based multimedia plugin) could be used on Raspberry Pi 2 and if it could be used to play more than one video contemporarily.[...]
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 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[...]
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[...]
For those of you still working on this exciting subject, I did some new changes to PiOmxTextures and it still works pretty good. To have more information on PiOmxTextures refer[...]
