Firewire camera capture. More...

Firewire camera capture.

The camera1394 driver captures images from IEEE1394 (Firewire, iLink) cameras.

Compile-time dependencies

• libraw1394
• libdc1394_control

Provides

• camera

Requires

• none

Configuration requests

• none

Configuration file options

• guid (string [16 digits])
• Default: None
• The GUID of the 1394 camera to use (only for libdc1394 >= 2.0)
• Example: guid "0800460200060121"
• Currently, if using libdc1394 >= 2.0
  • You should use GUID if you are on port > 0
  • To get GUID, run Player once with no GUID and look at the .player log file for the GUID of detected cameras.

• port (integer)
• Default: 0
• The 1394 port the camera is attached to.
• v2 of the dc1394 API no longer supports ports other than 0. If your camera is on a port > 0, and you are on Linux, you probably have /usr/include/dc1394/linux/control.h, which should allow you to use ports > 0 (if this file was detected during ./configure). Otherwise, use the GUID of the camera.

• node (integer)
• Default: 0
• The node within the port

• framerate (float)
• Default: 15
• Requested frame rate (frames/second)

• mode (string)
• Default: "640x480_yuv422"
• Capture mode (size and color layour). Valid modes are:
• "320x240_yuv422"
• "640x480_mono"
• "640x480_yuv422"
• "640x480_rgb"
• "800x600_mono"
• "800x600_yuv422" - will be rescaled to 600x450
• "1024x768_mono"
• "1024x768_yuv422" - will be rescaled to 512x384
• "1280x960_mono"
• "1280x960_yuv422" - will be rescaled to 640x480
• "FORMAT7_MODE0" - only available with libdc1394 >= 2.0
• Currently, all mono modes will produce 8-bit monochrome images unless a color decoding option is provided (see bayer).
• All yuv422 modes are converted to RGB24

• force_raw (integer)
• Default: 0
• Force the driver to use (slow) memory capture instead of DMA transfer (for buggy 1394 drivers).

• save (integer)
• Default: 0
• Debugging option: set this to write each frame as an image file on disk.

• bayer (string)
• Default: None.
• Bayer color decoding options for cameras such as the Point Grey Dragonfly and Bummblebee. Option activates color decoding and specifies the Bayer color pattern. Valid modes are:
• "BGGR"
• "GRBG"
• "RGGB"
• "GBRG"

• method (string)
• Default: None (or "DownSample" if bayer option is specified)
• Determines the algorithm used for Bayer coloro decoding. Valid modes are:
• "DownSample"
• "Nearest"
• "Edge"

• brightness (string or unsigned int)
• Default: None
• Sets the camera brightness setting. Valid modes are:
• "auto"
• any suitable unsigned integer

• exposure (string or unsigned int)
• Default: None
• Sets the camera exposure setting. Valid modes are:
• "auto"
• any suitable unsigned integer

• shutter (string or unsigned int)
• Default: None
• Sets the camera shutter setting. Valid modes are:
• "auto"
• any suitable unsigned integer

• gain (string or unsigned int)
• Default: None
• Sets the camera gain setting. Valid modes are:
• "auto"
• any suitable unsigned integer

• whitebalance (string)
• Default: None
• Sets the manual camera white balance setting. Valid modes are:
• "auto" (only for dc1394 v2)
• a string containing two suitable blue and red value unsigned integers

• dma_buffers
• Default: 4
• the number of DMA buffers to use

• iso_speed (unsigned int)
• Default: 400
• Sets the data rate of the 1394 bus. Valid rates are 100, 200, 400, 800, 1600, 3200.
