Feature request: Triggering camera functions/commands

[aazhuang2]

Are there any plans to expose a way to trigger basler camera's commands, like TimestampLatch and SoftwareSignalPulse through either a glib object signal or exposing the underlying camera device pointer for pylon? As I have seen the wiki page on Gige cameras for software triggered acquisition via actions commands, I was looking for something more general that includes the other commands as well as support USB3.0 cameras.

Hi @aazhuang2,

how to support these commands features is under discussion.

As gstreamer doesn't offer the type of "command" ( only string, int, float, bool ) there is no direct mapping possible.

Current options are:

• map e.g. SoftwareSignalPulse.Execute() -> to writing a '1' to an int feature 'SoftwareSignalPulse' which automatically flip back to '0' after executing the command.
• map all command features of the camera to gstreamer events or the message bus. Executing the command would require to send a gstreamer message or event.
