dv1394 driver is unsupported

[Carl Karsten]

When I plug in a firewire dv cam:

I am experiencing various problems with dvgrab: segfault, app stalls (doesn't error or exit, keeps output file open, but stops writing to it.) I will report them when I have a good example, but for this report this might be a good reason to "Use raw1394 instead."

Hi Carl,

It appears raw1394 is being used based on the line in your dmesg output:

[ 125.061687] ieee1394: raw1394: /dev/raw1394 device initialized

dvgrab v3 uses only raw1394, not the dv1394 kernel module.

The dv1394 special-purpose driver will actually stay in the kernel as log as the whole ieee1394 driver stack. But the new alternative firewire stack, which is meant to replace the ieee1394 stack eventually, won't provide an interface with binary compatibility to the dv1394 driver's interface.

I guess I should change the dv1394 driver to emit the scary log message only when actually opened by an application, not immediately when the driver is initialized.

For the record: The capture stalls which Carl mentioned are tracked in bug 298579.
