Hi all,
I'm trying to stream my Pi Camera 3 from Pi4B (Bookworm) over network using python and gstreamer.
When I use this launch string it works fine:
However, it's a software encoder, and I want to use HW acceleration.
So, I've changed encoder to v4l2h264enc:And it doesn't work with ffplay:Just hanging in this state and doesn't output anything.
From the GStreamer side I see this:
So, obviously, I'm doing something wrong. But what?
