Hello !
Let’s gather informations and discoveries on what you tested in order to get 1080p videos playing smoothly at 30fps. The idea is to refresh the old topics with latest Rpi 3, OF 0.10, and Raspbian Stretch, if that even matters…

I am using and developing with ofxPiMapper, and it uses ofxOMXPlayer.

I ran a few tests myself but I’m sure a lot of people here did go further than me and this is very interesting for a lot of Raspberry Pi users, as long as OF is not ported on another more GPU powered board like UDOO or else.

If you understand how OMXPlayer works internally, what can be the least GPU consuming tricks for videos ? Playing RAW video would help ?

How can I measure the GPU usage while testing different videos ? (My CPU is not at all too busy) I tried overclock it to 500MHz but didn’t get significant results.

Let’s share anything we have ! Cheers.

I’m having trouble playing a video with sound on a Raspberry Pi using the native ofVideoPlayer. The sound will start playing with the video but will quickly drift out of sync and eventually just stop playing. All this happens very quickly, in under 10 seconds.

The video is encoded in H.264 and the sound in AAC at 48 Khz. I’m using the HDMI output for audio. If I play the same video using the omxplayer command in the shell, it plays with no problems.

Could this be a memory issue or is there a setting I’m missing somewhere? Any help or suggestions is appreciated. Thanks!

I am looking for a read only script for stretch (not lite). I have found a lot of things these last few days but nothing that will do read only for stretch and work with the latest OF from git. I do have a USB stick in the pi to read and write changing files, and it is faster than the SD card so I can redirect swaps and whatever I need to there.

The main reason is I want this device to be able to be hard unplugged, there is not really a good way for a shutdown sequence. If anyone has any good pointers it would be great to know.

I would appreciate any advice how to resolve this.

I then found the instructions for installing on Linux here: https://openframeworks.cc/setup/linux-install/

However, while the dependencies and codecs found in openframeworks/scripts/Linux/ubuntu can be executed, when I go to the next line:

This is on a NVidia Jetson TX2, which has an arm8 processor, but I didn’t know there were only arm6 and arm7 versions of openframeworks.

is there a way to install openframeworks onto this device? Is there a way to delete what is here already if I cannot?

Hi all,

I’m trying to get a Raspberry Pi (3, B+) to run an app at 2560x1440 resolution. However, whenever I call ofSetupOpenGL with a dimension larger than 2048, I get an “egl_bad_native_window” error, followed by a lot of “egl swapbuffers failed” errors. (no extra code in ofApp.cpp past the default template)

I’ve tried doing it by calling ofSetupOpenGL at a smaller resolution (e.g. 500 x 500), then using ofSetWindowShape(2560, 1440). This seems to do something, but there are some black bars and positioning oddities: while the app reports its width is 2560 (using ofGetWidth()), things under the hood clearly aren’t happy.

Before ploughing on with weird hacks, thought I’d ask here. What’s the proper way of running a large-resolution app on the Pi? Is it possible, or is 2k some sort of hard limit for the hardware?

Cheers,
Digl

Hi all,

I’m working on a Raspberry Pi project (RPi 3 B+) with a high resolution screen (2560x1440) (OF version 0.10.0_linuxarmv6l). The project has very simple graphics, but needs the background to not automatically redraw.

Raspberry Pi’s ofSetBackgroundAuto is currently bugged and will continue to draw the background even when set to false (Github issue). The current workaround is to use FBOs - these work, but are a massive hit on my framerate (60fps -> 20fps).

Is there an adjustment to the openFrameworks source I can make to quick-fix the ofSetBackgroundAuto problem? I don’t know much about the source or re-compiling it so this may be unpractical.

Alternatively, is there a more efficient workaround than using FBOs? Or a more efficient way to use them? The performance impact comes from the fbo.draw() call in my draw() loop.

Many thanks,
Digl

if I type

#include "ofLog.h"

In LUTPass.h to get rid of the message of it complaining about ofLogError() not being found, it still gives me the same error.

If anyone can point me in the right direction I would greatly appreciate it!

Thanks,

Hi there,

I’m trying to learn how to cross-compile on my Mac running OS X 10.13.3 for my Raspberry Pi 3 B+ running Stretch.

I’ve tried doing this using the VM method outlined in this thread: Cross compiler for OF 0.9.0/Jessie/arm6/RPi1, but I got stuck on the step where I had to actually mount the RPI as a network drive on the VM (however, mounting on my Mac works fine).

I’ve found another resource online for cross-compiling that provides a precompiled toolchain here: Cross compiler for OF 0.9.0/Jessie/arm6/RPi1

Using the guide outlined here: https://openframeworks.cc/setup/raspberrypi/raspberry-pi-cross-compiling-guide/ I tried running this command:

make TOOLCHAIN_ROOT=/Volumes/xtools/armv8-rpi3-linux-gnueabihf/bin GCC_PREFIX=armv8-rpi3-linux-gnueabihf RPI_ROOT=/Volumes/Data/home/pi

Which produces this error:

HOST_OS=Darwin
/Volumes/Data/home/pi/openFrameworks/libs/openFrameworksCompiled/project/makefileCommon/config.shared.mk:86: *** commands commence before first target.  Stop.

I’m very new to this so I’m sure there’s something very obvious that I’m doing wrong. I would rather compile the code on my mac without having to use a VM if possible. Could anyone point me in the right direction?

EDIT: I’m taking a look at the steps here in the meantime: https://openframeworks.cc/setup/raspberrypi/raspberry-pi-cross-compiling-guide-wheezy/

I just set up my Rsapberry Pi 3 B and now I am trying to connect it to openFrameworks. I am following this tutorial https://openframeworks.cc/setup/raspberrypi/raspberry-pi-getting-started/ but I get an error on the step where I need to install the necessary packages. I was previously also getting an error on the dowloading openFrameworks step but then I just did that step manually (without using the Shell) and I think that’s fine now, hopefully no problems there. Any suggestions?
