imx8qxp camera display

OLED로 동영상을 Play하면 잘 됩니다

[joanxie]

what's your question? pls try to post again in English, thanks

[yoonseok]

Use imx8qxxp.
Parallellcd to HDMI is for debug, and LVDS-OLED is for actual use.
The camera resolution is 1920 x 1080.

With HDMI output, the camera video comes out well (800 x 600).
LVD-OLED (1920x1080) seems to have a lower number of frames,
If I shake the camera slowly, it looks like a video is flowing.

Please help me.

[joanxie]

what bsp do you test? what LVDS-OLED do you use? and pls share your log file

[yoonseok]

Is there a program or sample code that can test the camera capture? (from imx8qxp)

[joanxie]

one can use gstreamer to test, like

"gst-launch-1.0 v4l2src ! video/x-raw,width=640,height=480 ! waylandsink"

[yoonseok]

If you do it together as I told you, the number of frames only comes out about 20 to 22.

It's hard to measure if there are 30 frames.

[joanxie]

try to use this command to test:

v4l2-ctl -d /dev/videoX --set-fmt-video=width=xx,height=xx,pixelformat=YUYV --stream-mmap

change the X to your own test value

[yoonseok]

Thank you.
The number of frames is 30.
But the camera image is not displayed on the screen.

[joanxie]

yes, this command is for testing capture performance since you said you couldn't get 30fps, which show you the performance, so what do you need ? did you have any issue for gsteamer commands? the capture video isn't good enough?

[yoonseok]

Capture performance comes out well in 30 frames.
When captured and displayed (on Gstream), only 20 to 24 frames appear.
So, instead of gstream, I'm going to show you the performance of Capture & Preview 30 frame.
Can we check it out?

imx8qxp  에   hdmi 브릿지 칩을 이용해  Hdmi로 debug용으로  출력하거나  LVDB를 통해 OLED로 출력을하는 보드를 구성했읍니다

HDMI  800 x 600 ,  OLED   1920 x 1080  ,  camera 1920 x 1080

caemra에서  받은 imge을 HDMI로  출력하면 적정한 frame이 나오는데

camera에서 OLED 출력시 frame수가  적게 나오거나 image가 흐르는거 같아 보입니다

어떻게 하면 될까요?
