Hi,

I tried to execute the sample 10_camera_reording from latest 28.2.1 on TX2 board with built-in camera, but found it could not select the 120FPS mode ?

The change printed the supported frame duration range from the ISourceSettings,

*Frame Duration Range 33333334 83333336

So it only supports 30fps :(

Is there anything to be configured ? I noticed the argus_camera would select 1280*720@120 properly, have no idea about why.

Thank you very much.

Bump.

Is there anybody know how to improve this ?

Thanks.

Please prefer to ‘–sensor-mode’ in below sample:
