Hello @JohannH,

The best practices for controlling the exposure time on Linux depends on the platform.

You can use tools such as v4l2-ctl to set the exposure mode to manual/automatic and choose the exposure you want. The maximum exposure available is already computed to fit with the frame length you selected and to avoid any timing issue. 

You just need to be aware that some software stack such as libcamera with rpi might overwrite your controls. You need then to properly set your exposure controls at the libcamera level.

 

Best regards.

Jean
