Amancio, Randall, bt848 users, I've found some interesting features of the new ioctl which you may be able to help with. When in RGB24 mode, even fields only, it appears that the active region x_size must no less than 1.66 * image width eg. I want a 192x128 image. then active_region.x_size can be no less than 320. If my output image is 256x128 the active_region.x-size can be no less than 426. In YUV_12 mode there is no problem. Something in the Split code or the alignment?
