Hi,

According to the intel people, these are some additional setting to help latency that might be good to set as default:

There are some parameters affect latency. If you want low latency you can set async_depth to 1 and set bf to 0 (no b frames). https://github.com/intel/cartwheel-ffmpeg/issues/230#issuecomment-1432681842

B-frames count is always set to 0 with UltraGrid.
