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?
