I will try to add missing V4L formats - 8/10/12/16 bits RGB 4:4:4 MEDIA_BUS_FMT_RGB888_1X24 MEDIA_BUS_FMT_RGB101010_1X30 (to be added) MEDIA_BUS_FMT_RGB121212_1X36 (to be added) MEDIA_BUS_FMT_RGB161616_1X48 (to be added) - 8/10/12/16 bits YCbCr 4:4:4 MEDIA_BUS_FMT_YUV8_1X24 MEDIA_BUS_FMT_YUV10_1X30 MEDIA_BUS_FMT_YUV12_1X36 (to be added) MEDIA_BUS_FMT_YUV16_1X48 (to be added) - 8/10/12 bits YCbCr 4:2:2 MEDIA_BUS_FMT_UYVY8_1X16 MEDIA_BUS_FMT_UYVY10_1X20 MEDIA_BUS_FMT_UYVY12_1X24 - 8/10/12/16 bits YCbCr 4:2:0 Jose, how is supposed to be transmitted 4:2:0 over the controller ? Amlogic uses clock doubling to transmit 4:2:0 in CrYCb format. I assume, the transmission is in YYUYYV format in 2x clock. So the formats should be (aligned on the MEDIA_BUS_FMT_YUYV8_1_5X8) : MEDIA_BUS_FMT_YUYV8_1_1X24 (to be added) MEDIA_BUS_FMT_YUYV10_1_1X30 (to be added) MEDIA_BUS_FMT_YUYV12_1_1X36 (to be added) MEDIA_BUS_FMT_YUYV16_1_1X48 (to be added) to have the following transmissions scheme : uuuuuuuu/yyyyyyyy/yyyyyyyy vvvvvvvv/yyyyyyyy/yyyyyyyy Can you confirm this ?
