Re: info-beamer for PI - A digital signage player and more..

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...

Re: info-beamer for PI - A digital signage player and more..

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...

Re: info-beamer for PI - A digital signage player and more..

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.

Re: How do you develop for the Raspberry Pi?

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...

A visual watchdog

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...

Re: Programmically controlling FBI or another image viewer

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...

Re: How to rotate graphics at any angle?

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: [email protected]:/path/to/analog-d...

Re: pi3d - Fastest way to do dynamic text

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 ...

Re: egl_render texture flipped since firmware 45d99f5

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?

egl_render texture flipped since firmware 45d99f5

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...

Re: info-beamer for PI - A digital signage player and more..

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...

Re: info-beamer for PI - A digital signage player and more..

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 ...

Re: info-beamer for PI - A digital signage player and more..

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...

Re: info-beamer for PI - A digital signage player and more..

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 ...
