==========

--width,    -w        Set image width <size>
--height,    -h        Set image height <size>
--quality,  -q        Set jpeg quality <0 to 100>

Quality 100 is almost completely uncompressed. 75 is a good all round value

--raw,    -r        Add raw bayer data to jpeg metadata

This option inserts the raw Bayer data from the camera in to the JPEG metadata

--output    -o        Output filename <filename>.

Specify the output filename. If not specified, no file is saved. If the filename is '-', then all output is sent to stdout.

--verbose,    -v        Output verbose information during run

Outputs debugging/information messages during the program run.

--timeout,    -t        Time before takes picture and shuts down.

The program will run for this length of time, then take the capture (if output is specified). If not specified, this is set to 5 seconds

--timelapse,-tl        Timelapse mode.

The specific value is the time between shots in milliseconds. Note you should specify %d at the point in the filename where you want a frame count number to appear. e.g.

    -t 30000 -tl 2000 -o image%d.jpg

will produce a capture every 2 seconds, over a total period of 30s, named image1.jpg, image2.jpg..image15.jpg.

--thumb,    -th        Set thumbnail parameters (x:y:quality)

Allows specification of the thumbnail image inserted in to the JPEG file. If not specified, defaults are a size of 64x48 at quality 35.

--demo,     d         Run a demo mode <milliseconds>

This options cycles through range of camera options, no capture is done, the demo will end at the end of the timeout period, irrespective of whether all the options have been cycled. The time between cycles should be specified as a millisecond value.

--encoding,    -e        Encoding to use for output file

Valid options are jpg, bmp, gif and png. Note that unaccelerated image types (gif, png, bmp) will take much longer to save than JPG which is hardware accelerated. Also note that the filename suffix is completely ignored when encoding a file.

--exif,    -x        EXIF tag to apply to captures (format as 'key=value')

Allows the insertion of specific exif tags in to the JPEG image. You can have up to 32 exif tge entries. This is useful for things like adding GPS metadata. For example, to set the Longitude

    --exif GPS.GPSLongitude=5/1,10/1,15/100

would set the Longitude to 5degs, 10 minutes, 15 seconds. See exif documentation for more details on the range of tags available; the supported tags are as follows.

========

--width,    -w        Set image width <size>

Width of resulting video. This should be between 64 and 1920.

--height,    -h        Set image height <size>

Height of resulting video. This should be between 64 and 1080.

--bitrate,    -b        Set bitrate.

Use bits per second, so 10MBits/s would be -b 10000000. For H264, 1080p a high quality bitrate would be 15Mbits/s or more.

--output    -o        Output filename <filename>.

Specify the output filename. If not specified, no file is saved. If the filename is '-', then all output is sent to stdout.

--verbose,    -v        Output verbose information during run

Outputs debugging/information messages during the program run.

--timeout,    -t        Time before takes picture and shuts down.

The program will run for this length of time, then take the capture (if output is specified). If not specified, this is set to 5seconds

--demo,     d         Run a demo mode <milliseconds>

This options cycles through range of camera options, no capture is done, the demo will end at the end of the timeout period, irrespective of whether all the options have been cycled. The time between cycles should be specified as a millisecond value.

--framerate,     -fps  Specify the frames per second to record

At present, the minimum frame rate allowed is 2fps, the maximum is 30fps. This is likely to change in the future.

--penc,    -e    Display preview image *after* encoding

Switch on an option to display the preview after compression. This will show any compression artefacts in the preview window. In normal operation, the preview will show the camera output prior to being compressed. This option is not guaranteed to work in future releases.
