Does someone just AM> need to send in a pr? I cannot speak for Charles Henrich - so I'll let his comment do so (see below), my own contribution is definitely a hack of which I am far from proud. IMHO it works for the wrong reasons. I think the real problem lies in the YUV generation code for the on board processor and the patch works around it. It would be nice to add YUV420P to the on board set too but it made my brain ache badly last time I looked at it (see /usr/src/sys/dev/bktr/bktr_core.c *_prog() functions and you'll understand why). 2.19 19 Feb 2002 Charles Henrich (henrich@sigbus.com) Modified frame synchronization code to allow arbitrary field pattern matchin (i.e. 2 even, 1 odd makes one clean frame). This is probably bogus, but necessary for YUV format capture and frame signaling.
