Thanks AndyD and gkreidl. I'm going to submit an issue later. gkreidl, are you also using FullHD output resolution? I just tested it on a 1280x1024 screen using a DVI adapter and it works with the two hello_triangle and omxplayer commands above. But once I change the omxplayer win parameter to '0 0 ...

Can someone help me reproduce this? It would be very helpful to know if it is a hardware problem on my side or if there is some software problem. You don't have to install anything - they are available on Raspbian. Thanks in advance. I tried it on a Pi2 and B+. I bought a new power adapter with 2.1A...

I got weird behavior while developing my software. I was able to reproduce it using omxplayer and the hello_triangle example. On my PI 2 starting the following two programs makes my monitor (FullHD via HDMI+DVI Adapter, tvservice -s says state 0x120016 [DVI DMT (82) RGB full 16:9], 1920x1080 @ 60.00...

Hi. I'm having an OMX pipeline setup like this: decode[131]->[10]scheduler[11]->[90]render / clock[80]->[12]scheduler. I want to pause playback once the render component is displaying the first frame of a video so I can later start playback immediately. Currently I'm busy-polling the render componen...

An alternative might be using my software info-beamer . I created a gauge example you can clone from github: https://github.com/dividuum/info-beamer-nodes/tree/master/gauge Just download info-beamer. Then start info-beamer with the directory name of the above gauge code. You can change node.lua to s...

Yep, it's purely for debugging. Ok. Then it should work. What's the correct term I should be using for when something is output to a screen but not output onto a remote desktop connection? It'd hard to google solutions when I don't know what it's called. I don't think there's a specific term for th...

Is there any way to get the display to show via either of these remote access methods? You might be able to get output using this vnc server: https://github.com/hanzelpeter/dispmanx_vnc But don't expect a good framerate. I guess maximum is 1-2fps. So unless you're only using this for debugging it w...

I just released the latest version 0.8.3. You can grab it here. A blog post provide a description of changes in this version. If you have tried info-beamer previously I'd suggest you give the newest version a try. I used the last months to greatly improve performance.

I have these lines in config.txt initramfs initramfs.gz followkernel I don't have anything related to initramfs in cmdline.txt.

I'm developing in C using vim on my local Linux machine. I have a little script running in the background that basically uses inotifywait to monitor the file system for changes. Every time I save a file, make is triggered and cross compiles my project. If the project is build successful it uses rsyn...

I created a visual watchdog tool for the Pi that you can use to automatically detect if some visualisation/program you have running in fullscreen on your Pi didn't change the output on the screen. It's written in C and should compile/work out of the box. I wrote a small blog post about it here https...

You could use this script for my software info-beamer : https://github.com/dividuum/info-beamer-nodes/tree/master/remote-controlled-slideshow Basically you put the script and all the images you want display into a single directory and start info-beamer. It will run the script (node.lua) which provid...

I just threw together a quick proof of concept based on my tool info-beamer . I put the source code for the analog dial on github . To use it, first get info-beamer for the pi then put the analog-dial source into any directory and run info-beamer inside this directory: pi@raspberry:/path/to/analog-d...

I wish to have 3D graphics in the background with number text in the foreground. The number text is position and attitude data so it needs updating at a reasonable rate. I might offer a completely different approach. Just render the 3D with the tool of your choice. Then use my software info-beamer ...

Still seems to be a problem in firmware Mar 12 2014 15:45:44 Copyright (c) 2012 Broadcom version 8e98729958562dffea8130947e7e90669ac66001 (clean) (release)

Is the flipped output intended or is it a bug?

Hi. I'm using the egl_render to render decoded videos into OpenGL textures. Similar to the "hello_videocube" example in /opt/vc/. I noticed that the video is upside down since the latest firmware update. I compared different firmware versions and it only seems to be like that since this firmware rel...

I tried info-beamer on my 512Mb PI last night. It is quite impressive in certain aspects and it seems quite suitable for a signage project that I want to do. The main issue with digital signage is that it needs to run relatively smoothly - at about 30fps. The 'prices' example is still from the days...

Not at the moment. Sorry.

I released version 0.7-beta this week. It includes faster font rendering and faster JSON parsing using a native parser. Check it out

Thanks! That was the issue. The performance is about 43 fps now. Much better! Ok. I'd suggest using 720p videos. 1080p videos are close to the limit if you want to do anything else beside playing them. Have you put any thought into timers/scheduling? You have several options there: You could build ...

Hi. It looks like your video is loaded twice. Maybe you are using the autoloader and load the video manually? Can you try to load all your resources manually? Then you don't need the autoloader: font = resource.load_font("Huggable.ttf") video = util.videoplayer("big_buck_bunny_1080p_h264.mov") Regar...

Is it GPU accelerated? Yes. It's using a custom player. If you have playback problems, you might try to update your firmware to the latest release. I had problems with an earlier firmware too. Just run rpi-update (if you're on raspbian. Not sure about other distributions). If this doesn't fix your ...

Hi. I think it's time to present you the Raspberry Pi port of my software info-beamer: http://info-beamer.org/pi/ It's a multipurpose presentation tools fully programmable in Lua. It can load images, show videos or fonts. Everything is hardware accelerated when possible: Videos use OpenMAX, the pres...
