Add a genicam feature control property to aravis gstreamer plugin

[EmmanuelP]

Sometimes, using the gstreamer plugin, it is necessary to set some device feature in order to make it work properly.

A possible implementation would be to add a features property, that takes a list of feature/value pairs, similar to the parameters of the control command of arv-tool.

Then we could write:

gst-launch-1.0 aravissrc features="DeviceLinkThroughputLimit=185000000 ShutterMode=Rolling" ! videoconvert ! autovideosink

A very good idea. Just need to check for the few features that require being in the correct mode for their values to be manually set.

Hi @EmmanuelP .

Features command does not work for me.
gst-launch-1.0 aravissrc features="DeviceLinkThroughputLimit=185000000 ShutterMode=Rolling" ! videoconvert ! autovideosink

WARNING: erroneous pipeline: no property "features" in element "aravis0"

and by adding aravis source address:

gst-launch-1.0 -e --gst-plugin-path=/usr/local/lib/ aravissrc features="DeviceLinkThroughputLimit=185000000 ShutterMode=Rolling" ! videoconvert ! autovideosink

WARNING: erroneous pipeline: no property "features" in element "aravis0"

Hi @EmmanuelP,

Did you document all genicam features, or are you using the same feature key/val naming as genicam?

Hi,

Did you document all genicam features, or are you using the same feature key/val naming as genicam?

I fail to understand what you mean. Could you rephrase your question ?

[nrstrifork]

Let me try :)

You use the feature key/val naming convention like --DeviceLinkThroughputLimit=185000000 ShutterMode=Rolling-- Are these equal or corresponding to the Genicam convention, or did you create your own convention for all genicam features available for the aravissrc plugin?

Specifically, I'm trying to set features through the plugin but fail to find a full overview of available aravissrc plugin features

[EmmanuelP]

You can set any feature available on your camera, using the same syntax as the control command of arv-tool. You can list every available features using arv-tool-0.8 features.

Thank you :)
