Ps4eye under indigo

[thieri]

I am haveing trouble running this code with indigo.
Is there something to look for?
Is gscam the reason?
Keep getting "No space left on device" or "Failed to PAUSE stream, check your gstreamer configuration." errors.

Ubuntu 14.4 LTS vivid kernel 3.19+

Please check followings:

• Is the firmware updated?
  To check this, run lsusb,
  05a9:058a is correct, 05a9:0580 is bad.
• Is the device file correct?
  By the default, /dev/video1 is used.
  If camera is assigned to /dev/video0, please set device file via DEVICE arg.

roslaunch ps4eye stereo.launch DEVICE:=/dev/video0

Thanks for answering so fast,

sudo lsusb -v -d 05a9:058a gives the complete output,...

... and so on.

ls -la /dev/video0
crw-rw-rw-+ 1 root video 81, 0 Jan 18 17:14 /dev/video0

Device is correctly created, maybe permissions need "x"...

changed launchfile to /dev/video0
AND
ran it with
roslaunch ps4eye stereo.launch DEVICE:=/dev/video0 viewer:=true

result:

libv4l2: error turning on stream: Auf dem Gerät ist kein Speicherplatz mehr verfügbar

[FATAL] [1453133920.285989725]: Failed to initialize gscam stream!

error-message is german, for "No space left on device"

pyusb is 1.0.0b2
kernel is 3.19.0-46-generic
ps4eye is newest version

Any ideas?

after some googeling around...
sudo rmmod uvcvideo
sudo modprobe uvcvideo trace=1024

started nodelet

tail /var/log/kern.log
gave following output:

looks like it is demanding to much bandwidth

Sorry for all the trouble...

I think i sorted it out. The usb3 is on a expresscard, so maybe no full datarate. What is the combination of resolution/fps with the lowest possible datarate?

#19 may help you.

Use gscam instead. But, you need to get gscam compliled from its source. Also, there is one pitfall.

First, ros-indigo-gscam and ros-indigo-opencv2 do not exist. To solve this problem...

1. Clone gscam package.
2. Replace opencv2 with opencv3 in package.xml and resolve rosdep.
3. Built it.

Here is a command line instruction:

$ git clone https://github.com/yoshimalucky/gscam.git
$ git checkout indigo-devel-opencv3
$ rosdep install gscam
$ catkin b gscam

If you can not resolve the dependency on libgstreamer0.10-dev, install it manuallly:
$ sudo apt-get install libgstreamer0.10-dev

In issue #20 and #23, they are trying to use uvc_camera insterad of gscam.

I'm just wondering how to set device file for left and right camera with uvc_camera. It require two device files for each camera although there is one device file /dev/video1.
