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[...]
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[...]
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[...]
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[...]
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[...]
EDIT: This article is outdated.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:[...]
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[...]
Ok, I’ve been waiting to do this for quite some time but never had the time to actually do it. I tried this quickly twice but without success because of[...]
As requested I shared the sources of the demo videos I posted recently. I tested these components with a few videos and I saw that it seems to work “reasonably[...]
While working on completing the custom QML component for rendering video on Raspberry Pi, I asked myself: does it really make sense to always re-invent the wheel? And also, shouldn’t[...]
This is a custom QQuickItem subclass rendering hardware-decoded h264 1080p video on Raspberry Pi. The egl_render component used in some previous posts is good. The QML component can play nicely[...]
After accomplishing the target of decoding and rendering compressed image formats onto OpenGL textures directly using OpenMAX, I’ve looked into how to use the same concept to render h264 stream[...]
After building Qt 5.0 on Raspberry Pi, I focused the attention to hardware acceleration using OpenMAX. This is quite an interesting subject to study. The most interesting element I found[...]
EDIT: I see this post is still consulted very often. The solution below was the only one I found years ago. Now it seems that setting the env variable QT_QPA_EGLFS_FORCE888[...]
