hi,experts:

I want to set a mandatory I frame to the encoder v4l2h265enc, is there an interface for the application? Does the red box in the image below mean that the encoder implements the forced I-frame function?

Hi Qinghong,

Yes enabling this extra control will introduce an IDR frame for encoding.

Hi, Suren:

I am using gstreamer v4l2h265enc. How can I dynamically set mandatory I-frames through this plugin? Can you write an example?
