hello tangqc023,
please refer to Camera Architecture Stack;
Argus samples were based-on libargus library, which going through [Camera Core] block for handling sensor signaling. Hence, you cannot dump raw images at Argus level.
There’s only single approach to dump raw files. You should enable v4l2 standard controls, which bypass [Camera Core] block for accessing sensor device.
However, as our previous comments.
v4l2 standard controls should be not support to DOL-WDR raw files at current release versions.
thanks
