在imx6q 平台上使用下: ./mxc_vpu_test.out -D "-i  /opt/test.264 -f 2   -w 720 -h 480-j 0 -k 0 -x 16"  可以显示视频,但是屏幕非常闪烁,还有竖着的纹路。 但是使用 ./mxc_vpu_test.out -D "-i  /opt/test.264 -f 2   -w 720 -h 480-j 0 -k 0 -x 17" 时, 视屏显示正常, 这是什么问题呢?

what bsp version do you use? did you change anything on your board? x17 is overlay of x16, pls try to use command:

cat /sys/class/video4linux/video17/name and cat /sys/class/video4linux/video16/name, what do you get?
