hello EmondCai,
FYI,
v4l and nvarguscamerasrc they’re using different pipelines, as nvarguscamerasrc had more loadings at buffer transmits, for example, EGL is used by ARGUS APIs for buffer/stream management.
in addition, it might be performance bottleneck of video converter as well, (as you executed clocks.sh to to increase VIC clock shows better fps results)
hence,
please take your 206-fps evaluation results in comment #18 for current nvarguscamerasrc maximum frame-rate.
let me emphasize this again, we’ve never test such high frame-rate sensors.
please contact with sensor vendor for further supports. or, you may based-on 60-fps, or 120-fps sensor modes for your camera solution development.
