The nest SDM integration has been working well for the most part. However, when I try to view the stream from HomeKit video integration it appears to have a very slow frame rate. I suspect it’s due to a conservative default parameter. Doing ps | grep ffmpeg during a streaming of nest video feed I can see some of the parameters used in ffmpeg.

I could not find in any documentation guide as how to adjust these default parameters. I would greatly appreciate any tip on how to adjust this. Thank you.
Update looks like these parameters are from here
not sure where {v_max_bitrate} is defined though.
