Hello, i’m trying to get processing to work with my Raspberry Pi camera.

I made sure the camera is enabled in the Raspberry Pi Configuration tool. I also added “bcm2835\_v4l2” to /etc/modules.

The camera works properly, I can take pictures with it using  
`raspistill -o image.jpg`

I tried to run the SimpleCapture example from the GL Video library, but I get this error:

```auto
GLVideo: v4l2src1: Device '/dev/video0' is busy
Debugging information: gstv4l2object.c(3592): gst_v4l2_object_set_format_full (): /GstPipeline:pipeline1/GstV4l2Src:v4l2src1:
Call to S_FMT failed for YUYV @ 320x200: Device or resource busy
GLVideo: v4l2src1: Internal data stream error.
Debugging information: gstbasesrc.c(2939): gst_base_src_loop (): /GstPipeline:pipeline1/GstV4l2Src:v4l2src1:
streaming stopped, reason not-negotiated (-4)

```

Any ideas?

I used `GLVideo.enableDebug()` to get some more information.  
**Here are the results:**

**Here are the camera configs:**

```auto
Devices:
[0] "mmal service 16.1"
The format returned by configs() is informational only and might change in future versions of the library.
Configs:
[0] "video/x-raw, format=(string)YUY2, width=(int)[32, 2592, 2], height=(int)[32, 1944, 2], pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)progressive, colorimetry=(string){ bt601 }, framerate=(fraction)[1/1, 90/1]"
Final caps: video/x-raw(memory:GLMemory), width=(int)320, height=(int)200, framerate=(fraction)90/1, format=(string)RGBA, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)progressive, texture-target=(string)2D

```

I also tried running this in the terminal **sudo modprobe bcm2835-v412** as suggested by Ghans in an older post.  
Unfortunately I got this message after trying to run it **modprobe: FATAL: Module bcm2835-v412 not found in directory /lib/modules/4.14.79-v7+**

If anyone has any input, I would really appreciate the help!

But that doesn’t require the V4L2 driver module.

That should be bcm2835-v4l2 I think - an L (lower case) not a 1. Video 4 Linux 2.

I had some problem also the last time I tried to make my camera works. I finally got it to work by simply using the PI image you can find on the processing website.

Here is the discussion if you want to read it: [Issues with third-party camera](https://discourse.processing.org/t/issues-with-third-party-camera/2075/12). It was a third party camera by the time but now I’m using a PI camera.

I tried bcm2835-v4l2 with a lower case l, and it didn’t change anything.Did you get the image from from this page? [https://pi.processing.org/get-started/](https://pi.processing.org/get-started/)

Thanks for the help
