dc1394src

Source for IIDC (Instrumentation & Industrial Digital Camera) firewire cameras. If several cameras are connected to the system, the desired one can be selected by its GUID and an optional unit number (most cameras are single unit and do not require it). The frame size, rate and format are set from capabilities. Although the IIDC specification includes a raw video mode, many cameras use mono video modes to capture in Bayer format. Thus, for each mono video mode supported by a camera, both gray raw and Bayer corresponding video formats are exposed in the capabilities. The Bayer pattern is left unspecified.

Example launch lines

 gst-launch-1.0 -v dc1394src ! videoconvert ! autovideosink

Capture and display frames from the first camera available in the system.

 gst-launch-1.0 dc1394src guid=00074813004DF937 \
     ! "video/x-bayer,format=gbrg,width=1280,height=960,framerate=15/2" \
     ! bayer2rgb ! videoconvert ! autovideosink

Capture and display frames from a specific camera in the desired format.
