That was already posted on the list [1], there was some discussion but i don't know what's the status/plan to get it into mainline. And, as you can see in [2], don't expect many comments :D [1]: http://www.spinics.net/lists/linux-media/msg37710.html [2]: http://www.spinics.net/lists/linux-media/msg37116.html >> Even if it does detect the signal shape (NTSC, PAL), doesn't one still need >> to [externally] configure the pads for this shape? >> > > Yes, that is why I wanted to do the auto-detection for the tvp5151, so > we only have to manually configure the ISP components (or any other > hardware video processing pipeline entities, sorry for my > OMAP-specific comments). Laurent was not very happy [3] about changing video formats out of the driver control, so this should be discussed more.

I think you got it right, i haven't tested it but the output format shouldn't be affected by the video source( if it stays pal/ntsc of course). Maybe you will get only a different "active" video area so only cropping will be affected.
