That worked, but now there is another problem. yavta will set UYVY (PIX_FMT), this will cause a call to ispvideo.c:isp_video_pix_to_mbus(..), that will do this: for (i = 0; i < ARRAY_SIZE(formats); ++i) { if (formats[i].pixelformat == pix->pixelformat) break; } that is it will stop at the first matching array item, and that's: { V4L2_MBUS_FMT_UYVY8_1X16, V4L2_MBUS_FMT_UYVY8_1X16, V4L2_MBUS_FMT_UYVY8_1X16, 0, V4L2_PIX_FMT_UYVY, 16, 16, }, but you wanted this: { V4L2_MBUS_FMT_UYVY8_2X8, V4L2_MBUS_FMT_UYVY8_2X8, V4L2_MBUS_FMT_UYVY8_2X8, 0, V4L2_PIX_FMT_UYVY, 8, 16, }, so a better check could be to check for width too, but i don't know if it's possibile to pass a width requirement or if it's already there in some struct passed to the function.
