Thank you DaneLLL.
I cannot do in another way, I alter the frame in Python and I have BGR Math frame.
So in order to encode it using nvv4l2h264enc I need to convert it in a compatible format before.
So I’ve added BGR to BGRx conversion.
The similar discussion: [Gstreamer] nvvidconv, BGR as INPUT
Was open by me…
I’m exploring the possibility to remove BGR conversion but I found a big problem: Opencv VideoWriter doesn’t support 16-bit depth images, so I cannot pass an RGBA (or other 16-bit format) directly to gstreamer.
I’m forced to pass an RGB or BGR frame and convert it in CPU using gstreamer, so no way to prevent CPU usage.
