A while back, on the main Symbian blog, I announced that ISB were making a contribution that would enable camera-based use-cases in QEMU. Essentially the contribution would allow a webcam to be used on the host PC and to function like a camera on a phone.
To keep everyone updated on the progress of this contribution, I have created a wiki page. Please drop by, have a read, comment on the project and perhaps give some thought to getting involved! The contribution is initially focused on providing a complete vertical stack, but there is some horizontal diversification that would be of benefit. For example, to add support for additional brands of webcam, or support more advanced use-cases like scene modes.
