Hi. I’m trying to get back to this unresolved issue I submitted a while back.
The application I have has changed a bit since I first posted, and with newer versions of gstreamer, I was hoping to get this worked out. I have the same problem as before, but I recently noticed something I hadn’t before.
When the application initially starts up, and mfvideosrc is my src, I noticed this when I have GST_DEBUG set to mfvideosrc:5'

How do I make ICodecAPI available? I don’t have this issue using ksvideosrc .
