The IMPERX SDI cards support BGR, YUY2, and a unique 10-bit YUV 4:2:2 format which is not currently supported in GStreamer. For now, we'll unpack it to AYUV64. This has only been tested on a ExpressCard device, but is expected to work with all IMPERX grabbers that use this SDK. Special attention has not been given yet to timestamping or accounting for dropped frames. Currently if the source is interlaced this element will deinterlace. Another mode could be supported to push out the frames as is, with appropriate caps to indicate interlacing mode.
