Hello Denis, (sorry for spamming to your private mail address -- I simply pressed reply-to...)

Unfortunately, you can completely forget that. As you already mentioned, all saa7146s below revision 3 have the byte-swapping bug for video dma 1. So the only native yuv format the saa7146 can deliver is uyvy byteorder -- I don't know what v4l1 format this exactly is. (I have worked with the v4l2 format descriptions for too long...) I once added "software-support" for yuyv byteorder by swapping the bytes in software to my v4l2 driver -- unfortunately this seems to be the native byteorder of the bttv driver... So most applications tried yuyv before uyvy -- of course this resulted in really bad performance... ;-) Unfortunately, there is no way of telling the application what the "best" supported format is -- even with v4l2. Finally I removed this from my driver again, and wrote patches for the programs I was using ;-) So, all g200 users are out of luck here. In my eyes, the only solution is to add software swapping to the directfb- or the g200-driver, or to upgrade to a g400 (or higher)...
