I think the trunk version still only works with the first PVR350 it finds. The code I'm running now will initialize the osd on all the PVR350 cards it can find. I have two cards here and although I can control & write to each osd separately, trying to run something like X on both results in nothing working and the logs filling up with a mass of DMA errors.

It should be noted that ivtvdev ignores the requested framebuffer device & always grabs the first one it finds, so I ended up using a combination of ivtvdev & fbdev for the test. When that failed I tried fbdev for both, but it still didn't work. -- Ian _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
