Dear Laurent and others linux-UVC developers,
I'm writting the messages of ctrl that will be based on yours. I'm
trying to understand the meaning of the probe parameter of
uvc_vide.c::uvc_get_video_ctrl
Could you tell me it please?
See section 4.3.1.1 in the UVC 1.1 specification.
In addition, I want to know what is the value of bFormatIndex that It's the
last selected. Have I to query it?
The current bFormatIndex value can be retrieved with a GET_CUR request on the
video commit control.
What is the meaning of dwMaxVideoFrameSize?
For frame-based formats (stream-based formats are not supported by the
uvcvideo driver yet) the field stores the maximum size of a video frame.
and dwMaxPayloadTransferSize at still image controls point of view?
It has the same meaning as for the video controls.
