hi all,
does anyone have experience with the ps3eye in ubuntu using pd/gem?
I am trying out ubuntu for one of my systems and have the following issue.
I am able to control the frame rate, autogain and several other features of the PS3eye camera from GUVCViewer, but I cannot do it from GEM.
In GEM, when I open device 0 i get:
videoctl: device 0 info: proplist numread 13 info: proplist read Auto Gain float 1 info: proplist read Auto White Balance float 1 info: proplist read Brightness float 255 info: proplist read Contrast float 255 info: proplist read Exposure float 255 info: proplist read HFlip float 1 info: proplist read Light Frequency Filter float 1 info: proplist read Main Gain float 63 info: proplist read Sharpness float 63 info: proplist read VFlip float 1 info: proplist read bus_info symbol usb-0000:00:1d.7-5 info: proplist read card symbol USB Camera-B4.09.24.1 info: proplist read driver symbol ov534 info: proplist numwrite 10 info: proplist write Auto Gain float 1 info: proplist write Auto White Balance float 1 info: proplist write Brightness float 255 info: proplist write Contrast float 255 info: proplist write Exposure float 255 info: proplist write HFlip float 1 info: proplist write Light Frequency Filter float 1 info: proplist write Main Gain float 63 info: proplist write Sharpness float 63 info: proplist write VFlip float 1 v4l2: GEM: pix_video: Opened video connection 0xE
Could anyone suggest a way of controlling the camera so that GEM can use higher frame rates?
best,
J
oops i forgot the list
try apt-get v4l2ucp http://sourceforge.net/projects/v4l2ucp/
you have to invoke it with device as parameter
v4l2ucp /dev/video0
not sure for framerate

Gem won't (shan't) touch any settings of the device if it can help it. so setting the framerate before you start Gem should get you somewhere.
furthermore, it should be possible to change some properties of the camera even while Gem is capturing.
in the case of guvcview this might not work due to guvcview (which tries to also _capture_ images and fails doing so), but tools that only set properties should work ok. i'd recomment something simple like v4l2-ctl (on debian this is available in the v4l-utils package)
$ v4l2-ctl -d /dev/video0 -p 120
Could anyone suggest a way of controlling the camera so that GEM can use higher frame rates?
nevertheless, setting the framerate is currently really missing in Gem's v4l2 backend. please file a feature-request (for Gem!).

IOhannes,
guvcview can in fact control while Gem is running. Just use the right parameter:
guvcview --control-only /dev/video0
Thats actually how I use it.
