These testings are a bit inconclusive: 1280x720 @49fps: ~25ms 1280x720 @30fps: ~38ms 1280x720 @60fps: ~45ms For some reason, latency decreases by going from 30fps to 49fps but then greatly increases...
~58ms @1080p30 The flakiness seems to be in direct corelation with the frequency of the h264 encoder core / isp frequency But for some reason, on my rpi 3B+ it...
For my testings above I did not look at the gpu speed (using gpu as a synonym for h264_freq and isp_freq). That might explain the difference between 30 and 49fps
550mhz is the max I can get before it starts to get unstable. Note that I did not increase the power for the chip / voltage or something At fixed...
Dang, I've just spent 1h adding the "slices" param from raspivid to gstreamear rpicamsrc just to find out that enabling slices greatly increases encoding latency at 720p60 e.g. it goes...

Some facts about resolution and bandwidth: 1280*720*120=110592000 1920*1080*60=124416000 -> 720p120 is lower bandwidth than 1080p60 YUV420 has 6 bytes per 4 pixels. Aka 1.5 bytes per 1 pixel or 12...

yeah, if you are a developer you can join our telegram group.
How far away are we from a bootable image for rpi (bullseye) and jetson ?
