I am using libdc1394 2.0.0a7 and the CVS version of Player to grab frames frames from a PointGray Firefly MV use FORMAT7_MODE0.
The CVS version of the driver was not completely cleaning up on shutdown, causing me to have to restart the server after disconnecting the client, or I would get errors like this from the server upon reconnecting:
(capture.c) VIDEO1394_IOC_LISTEN_CHANNEL ioctl failed: Device or resource busy
Libdc1394 error (capture.c:dc1394_capture_setup:323): IOCTL failure : Could not setup DMA capture
warning : DMA capture failed; falling back on RAW method
error : unable to open camera in VIDE0 or RAW modes
error : unable to subscribe to camera device
This patch fixes the problem by adding a call to dc1394_camera_stop to the driver's Shutdown method, when using libdc1394 v2.0.
