help with cameras on raspbian

erwrow

Hi, as the title says, im having trouble when trying to access a USB webcam, im using the GL video library.

Is there any step to make this work? (i'm ready to reinstall if necessary), plus (if it helps) i'm exporting the application from my windows pc

The code that im trying to use is the SimpleCapture and the error is the following:

RunnableTask.run(): A caught exception occured on thread main-Display-.x11_:0.0-2-EDT-1: RunnableTask[enqueued true[executed false, flushed false], tTotal 0 ms, tExec 0 ms, tQueue 0 ms, attachment null, throwable java.lang.RuntimeException: Waited 5000ms for: <1d0892e, 1ed8535>[count 1, qsz 0, owner <main-FPSAWTAnimator#00-Timer0>] - <main-Display-.x11_:0.0-2-EDT-1>]

@erwrow The error essentially means that some part of the process of rendering a frame stalled for so long that JOGL essentially gave up at some point.

Couple of options:

• you might want to try the regular Video library, since the USB webcam is not hardware-accelerated on the Pi anyhow

• you might want to try using a lower resolution or framerate, to see if this improves things

• using a camera module for the Raspberry Pi should also be much faster

the regular video library isn't available for processing on raspbian (as far as i know)

you might want to try using a lower resolution or framerate, to see if this improves things

I just tried with the lowest resolution (and framerate) that my camera allows me (160*120 at 15 fps) and the error that throws me i've passed it at the bottom of this answer.

using a camera module for the Raspberry Pi should also be much faster

i don't have the camera module and on my country is expensive :/

from already thank you very much for the answer

@erwrow Which Raspberry Pi model are you trying this with?

The regular Video library does work - but you might need to install the package gstreamer0.10-plugins-good. See: https://github.com/processing/processing/wiki/Raspberry-Pi#video-library-capture

Raspberry Pi 3 b with raspbian

Yes, i was that (you're a genius jaja).

Thank you very much!!!

Hi,

In the error logs shown before what means "that some part of the process of rendering a frame stalled for so long that JOGL essentially gave up at some point."? Is it "Final caps: video/x-raw(memory:GLMemory), width=(int)640, height=(int)480, framerate=(fraction)30/1, format=(string)RGBA, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)progressive, texture-target=(string)2D"? It's the only output I have with a sketch which works with an USB webcam but not the raspicam module.
