Omxh264enc control-rate CBR vs CBR-skip

What is the difference between omxh264enc control-rate=2 (constant) and omxh264enc control-rate=4 (constant-skip-frames)?

The Accelerated GStreamer guide does not give a very good description of these parameters. It only says “Constant Bit Rate” and “Constant Bit Rate with frame skip”.

Running in control-rate=4, if stream data size is achieved, it drops rest frames. For example, in 30fps, 4Mbps, it has achieved 4Mbits in encoding 20 frames, the rest 10 frames are dropped.

We have deprecated omx plugins, so suggest you use v4l 2plugins. The mode is not supported in nvv4l2h264enc. Please run in CBR mode.
