Detecting whether the effects from the opengl plugin can be used

[Alexandru Băluț]

In Pitivi we'd like to hide the GL effects when the system has no GL component. A quick inspection (gst-inspect-1.0 | grep -i gl) shows these effects are provided by the "opengl" plugin, so for now we only care about the "opengl" plugin from gst-plugins-bad.

How can we programmatically figure out beforehand whether these effects can be used?

Thanks,

Alex

Hi Alex,

Could you try to link opengl into your pipeline and see if you were
successful?

Hi Ian,

What is the simplest pipeline I could create to check this?

Thanks,

Alex

gltestsrc ! gleffects ! fakesink

or some variant.

Set pipeline to paused.
If no error, then you're 99% ok with using the opengl elements.
