Issue Description

<Describe your issue / question / feature request / etc..>

Hello, I would like to use high-speed capture mode by using the 300fps monochrome image stream via the IR cameras; as described in the 2020 white-paper: https://dev.intelrealsense.com/docs/high-speed-capture-mode-of-intel-realsense-depth-camera-d435

the following way: pipeline_profile = cfg.resolve(pipe) device = pipeline_profile.get_device()

for sensor in device.sensors: if sensor.name == 'Stereo Module': for profile in sensor.profiles: if profile.stream_type() == rs.stream.infrared: cfg.enable_stream(profile.stream_type(), 1, 848, 100, rs.format.y8, 300)

pipe.start(cfg)

I somehow cannot get above 60 FPS. I am using Python 3.11 and OpenCV

Thanks for any suggestions!

best regards,

Bertie

Hi @BertieBcs 848x100 High Speed Capture mode is supported on D435 for the depth and infrared streams, so you should be able to access the infrared stream at 300 FPS with Python code.

Do you get a Couldn't resolve requests error if you try to use an FPS higher than 60, or does the stream just seem much slower than it should be

Is 300 FPS provided if the simple test script below is used?

import pyrealsense2 as rs

pipeline = rs.pipeline()
cfg = rs.config()
cfg.enable_stream(rs.stream.infrared, 848, 100, rs.format.y8, 300)

pipe.start(cfg)
