Hello Lars

Which firmware did you write into the camera? Could you try dmk42uc03_143.euvc?
Also please use a lower frame rate. The Raspberry PI can not handle 30 fps.

Please let me me know your results.

from tiscamera.

Hi Stefan!
I've written dmk_42_uc03_143.euvc to the camera, set it to uvc-mode afterwards and rebooted the system.

Result:

root@raspberrypi-Helmut:~# gst-launch-0.10 v4l2src ! video/x-raw-gray,width=1200,height=960,framerate=30/1 ! tis_auto_exposure ! tiswhitebalance ! tiscolorize ! bayer2rgb ! ffmpegcolorspace ! videoscale ! ximagesink
WARNUNG: Fehlerhafte Leitung: tis_auto_exposure0 konnte nicht mit tiswhitebalance0 verknüpft werden

Same with other framerates. GST_PLUGIN_PATH is set as needed.

A Bit more detailed:

Lars

The tis_colorize module must be in front of the tis_whitebalance module, otherwise the whitebalance thinks, there is no color format in use

Please see the sample pipeline at the bottom of:
https://github.com/TheImagingSource/tiscamera/wiki/Raspberry-PI-start
(different camera, therefore 640x480 resolution. Change to 1280x960)

Sometimes the problem sits in front of the computer. ;-)
Thanks, now I get to see at least a video stream. A good base for further image processing. I'm confident, that all the other gstreamer-modules will help me developing a fine result.

I consider this issue solved.

A hint for all other users: Take care that you use only feasable resolutions and framerates, that your camera supports.
It took me several tries to find out that I mistyped here (1200x960 instead of 1280x960).

Hello,

I'm following the same instructions, but i get: "WARNING: erroneous pipeline: no element "tis_auto_exposure"" when I type the command:
gst-launch-0.10 v4l2src ! video/x-raw-gray,width=640,height=480,framerate=15/1 ! videorate ! video/x-raw-gray,framerate=3/2 ! tis_auto_exposure ! tiscolorize ! tiswhitebalance ! bayer2rgb ! ffmpegcolorspace ! ximagesink

Do you guys know what is going on?

I'm using a DFK 72BUC02.
The firmware is dmk72uc02_146.euvc and I have gstreamer0.10 and gstreamer1.0 installed.

Another issue is when I try to use mplayer or fswebcam, the pictures are gray. Not colorful.
Is it a problem with the firmware?

Thank you!

from tiscamera.

Hello

1.) Did you compile the gstreamer modules? Please refer to https://github.com/TheImagingSource/tiscamera/tree/master/src
2.) After you compile the gstreamer modules, you start the gstreamer pipeline from the directory, where they are created in, or you set the environment variable GST_PLUGIN_PATH as shown at https://github.com/TheImagingSource/tiscamera/wiki/Linux-Support-via-Gstreamer-Modules

3.) The DFK 72 provides sensor raw data only. This must be transformed to RGB colors in the computer. This is called debayering If your mplayer and fswebcam do not show a color image, then they do not debayer the raw data, I think, this is the expected behavior of standard software.
