Possibility to reduce framerate? about hololens2forcv HOT 3 OPEN

The API does not allow for controlling the sensor frame rates. You can try to modify the app recording loops to drop frames or use sleeps to slow down the capture rate.

Yes, one way to reduce the framerate inside the app could be to modify the IsNewTimestamp function in
RMCameraReader into a function that checks if the difference in timestamps is greater than a given threshold.

In general, the StreamRecorder app offers a demo about capture capabilities, but for specific uses it should be customized and optimized. For instances, hand tracking data is saved in main memory and just dumped to disk only at the end of each capture sequence. This might be problematic for very long captures.

Hi @fehmerli,
in case you are still interested, i modified the IsNewTimestamp function to enforce a minimal difference of minDelta (in Hundreds of Nanoseconds) between frames. Maybe it is useful to you:
