Raspberry HD camera V2 dont work

[Kjell Berge]

Hi, I have instaled a Raspberry HD camera V2  to Raspberry Pi3 and a Pi Touch Display.

raspistill and raspivid work correctly.

I have installed kivi and it work.

I have also install rpi, I dont know what this is for.

But if I Run kivi/examples/camera/main.py I get an error:

>> 6: resolution: (600, 480)

TypeError: 'NonType' object is not callable.

kivi/examples/demo/camera_puzzle.py I get error:

resolution=self.resolution, stopped= True)

TypeError: 'NonType' object is not callable.

Is there something I have forgott?

All other demos and exampels work.

In exampele reads:

Note that not finding a camera, perhaps because gstreamer is not installed.

How do I install Gstreamer?

I have tried: sudo apt-get install gst-plugins-good1.0 (and 0.10).

I get: E: Unable to locate package gst-plugins-good1.0

E: Couldn't find any package by regec 'gst-plugins-good1.0

Can sombody help me?'

[Kjell Berge]

I have installed gstreamer0.1, but the result is the same.

Any ideas?

Can anybody help me?

Here is Kivi logfile

In my opinion, you need to install kivy.deps.gstreamer.
But I don't know how to install kivy.deps.gstreamer. Because the website could find the package.

I have installed gstreamer1.0 (apt-get -y installgstreamer1.0-plugins-{bad,base,good,ugly} gstreamer1.0-{omx,alsa}

But the result is still the same.

[Kjell Berge]

I think the definition of "camera" is missing.

I get the message: "[CRITICAL] Camera: Unable to find any valuable Camera providers."

I am about to give up, can anyone help me please.

Here is the demo program:

Camera Example

==============

This example demonstrates a simple use of the camera. It shows a window with

a buttoned labelled 'play' to turn the camera on and off. Note that

not finding a camera, perhaps because gstreamer is not installed, will

throw an exception during the kv language processing.

Hi,
refer the source code

kivy/kivy/lib/gstplayer/_gstplayer.h

    

#include <glib.h>

#include <gst/gst.h>
       .
       .

It seems need to install the development packages on the device.
