| value | description |
|---|---|
| 0x0 | Stream mode |
| 0x1 | Capture mode |
Stream mode: stream output
Caputre mode: output the next frame each capture cmd.
5.15 nodf
Requirements：hdver >= 0x3, effective in Stream mode
Number of dropped frames
It is a method of framerate control, output one frame,discard nodf frames,output next frame, and so on.
actual framerate = original framerate /（1+nodf）
For example，if the original framerate is 30fps, set nodf to 2, then actual framerate is 10fps.
./veye_mipi_i2c.sh -r -f nodf
./veye_mipi_i2c.sh -w -f nodf -p1 [value]
ntof range is [0-0xFF]， default 0.
5.16 capture
Requirements：hdver >= 0x3, effective in Capture mode
./veye_mipi_i2c.sh -w -f capture
Output the next frame. This cmd does not interfere the sensor, it just output the next frame (the newest frame).
So it is not trigger mode, there will be a delay[0,1/framerate] between the cmd and the frame exposure.
It is applicable to those that do not require a high level of real-time performance.
