                    file

Scan OpenNI ONI files

positional arguments:
  file                  ONI filename

optional arguments:
  -h, --help            show this help message and exit
  --info
  --times               print times of each frame
  --seeks               print seeks
  --dump
  --copy                simply copies the content of the ONI via parsing
                        (rebuilds the seektable only)
  --rescale RESCALE     rescale timings
  --fixcut              fixes cut file NOT TESTED HERE
  --checkcut            checks if file was cut NOT TESTED HERE
  --dupframes DUPFRAMES
                        duplicate frames
  --stripcolor
  --stripdepth
  --stripir             removes IR
  --registercolor       registers color over depth
  --registerdepth       registers depth over color
  --mjpeg               extract the color stream as motion jpeg
  --extractcolor EXTRACTCOLOR
                        extract the color stream single jpeg or png images.
                        This option specifies the target path, numbering is
                        the frame number
  --extractdepth EXTRACTDEPTH
                        extract the depth stream single png images. This
                        option specifies the target path, numbering is the
                        frame number
  --extractir EXTRACTIR
                        extract the depth stream single png images. This
                        option specifies the target path, numbering is the
                        frame number
  --fseek FSEEK         seek frame for extract
  --fduration FDURATION
                        duration of extraction in frames
  --skipframes SKIPFRAMES
                        skip n frames
  --coloreddepth        colored depth
  --output OUTPUT
  --cutbytime CUTBYTIME
                        cut by specifing time in seconds:
                        startseconds,endseconds
  --cutbyframe CUTBYFRAME
                        cut by specifing time in frames: startframe,endframe
```
