Triggering with Vimbasrc

[nirushka]

Hi,

We are using Alvium 1800 U-319 USB3 camera with vimbasrc and we would like to understand how to use an external triggering.
There are no examples or explanations for that.

I see that there are some elements in the vimbasrc but I can't understand their use:

1. triggerselector
2. triggermode
3. triggersource
4. triggeractivation

Our main goal is to send a hardware signal to the camera in order to start the grabbing process (we can send a trigger for each frame as well)
Furthermore, should we connect to the camera GPIO in order to do this?

Hi, the features correspond to the GenICam features of the camera. Have a look at the Feature Reference for the cameras to see the possible settings and what they do.
For Alvium cameras: https://cdn.alliedvision.com/fileadmin/content/documents/products/cameras/various/features/Alvium_Features_Reference.pdf

In the pipeline it should look like this:
gst-launch-1.0 vmbsrc camera=DEV_00012D013844 triggeractivation=RisingEdge triggermode=On triggerselector=FrameStart triggersource=Line0 exposureauto=Once ! video/x-raw,format=GRAY16_LE ! videoconvert ! queue ! autovideosink
