[gst-devel] Firewire cameras with DirectShow

Hi Julien,

Thanks for the quick reply.

There is only one filter under the Video Capture Sources group: the
Microsoft DV Camera and VCR. There are two output pins: DV A/V Out and DV
Vid Out. All of the properties in DV A/V Out are disabled and are either
empty or set to 'None', with the exception of the color space/compression
(which is probably the one we're interested in) which is set to dvsd.

The properties for DV Vid Out are the same as above, but without the color
space/compression set.

If it would help I could piece together a screenshot of the contents of the
filter from the 'Insert Filters' dialog, although it doesn't look like it
will provide much more information.

Thanks again,
