Overview

Record is the basic rich-media capture activity for the laptop. It lets you capture still images, video, and/or audio. It has a simple interface and works in both laptop and ebook mode. An interface for sharing pictures among multi XOs during a picture-taking session is a hallmark of the Record activity.

Using Record with external cameras

If the camera is recognized, a device /dev/video1 will be created. You may need check using Terminal. The internal device is usually /dev/video0, but this is not guaranteed.

To use a external camera, you can apply this patch

diff --git a/glive.py b/glive.py
index 9f8c5fa..d2207e7 100644
--- a/glive.py
+++ b/glive.py

     def _detect_camera(self):
         v4l2src = gst.element_factory_make('v4l2src')
+        v4l2src.set_property('device', '/dev/video1')
         if v4l2src.props.device_name is None:
             return

Supporting more than one camera without a patch is the subject of ticket #4859.
