Are there some application available to use this v4l2-mem2mem? There is no other interface for jpeg codec hardware in V4L2 as far as I am aware anyway. That's why mem2mem has been developed in the first place. Mem2mem has just been released (in 2.6.35), so you have to give it some time. That said, I don't think you will find any other (non-mem2mem) V4L2-based applications for jpeg hardware either. Somebody might prove me wrong on this though...
