That would be great ! > I wanted to check if anyone is working to get this module working. Not to my knowledge. I'm not (at least for now, but I could need H3A support at some point in the future). > Is OMAP3 H3A similar or same as OMAP4 H3A. Can i make use of the OMAP3 code > base for h3a or how complex is this activity? The AF and AE engines look pretty similar indeed. It would be nice if the OMAP3 ISP AF and AE code could be shared with the OMAP4 ISS driver. That would require some refactoring though. One thing we're missing is standardization of H3A APIs in V4L2, I'd like to see that happen. > Also, i wanted to how how to test the v4l resizer driver in omap4iss? Here's the full pipeline configuration I use. Please note that the OMAP4 ISS resizer implementation doesn't support resizing yet, it just hardcodes the resizer ratio to 1:1.
