The image_acquisition package is part of the Octave Forge project.

There is not release package yet but if you can get the source here [1]

Example session

Using v4l2loopback for tests

If you don't have a v4l2 device but test the package you could create a loopback device:

modprobe v4l2loopback
gst-launch-0.10 videotestsrc ! v4l2sink device=/dev/video0

Reporting bugs

Please install v4l2-ctl (for example from Debian package v4l-utils), run the following commands and attach the output.

$ v4l2-ctl -w --list-devices
$ v4l2-ctl -w -D
$ v4l2-ctl -w -L
$ v4l2-ctl -w -n
$ v4l2-ctl -w --list-formats

Enable libv4l2 logging:

$ export LIBV4L2_LOG_FILENAME=libv4l2_debug.log

Start octave and execute your commands/scripts which show the problem.

Please include the whole octave session beginning with the start of octave. There might be some warnings like "warning: function xyz shadows a built-in function" at start.

Exit octave and add libv4l2_debug.log to your bug report

Consider running the included tests:

test @videoinput/videoinput
test @videoinput/get
test @videoinput/set
test @videoinput/getsnapshot
