Hi community,

 

I have a question about i.MX6SDL.

When preview UVC camera image with gstreamer 0.1 in i.MX6SDL L3.14.28 BSP, noise was occurred.

Please see the attached file, the white spots are noise.(not grime on the screen or on my suit)

Our command is as below.

 

#export VSALPHA=1

#gst-launch v4l2src ! image/jpeg, width=1920, height=1080, framerate=30/1, rate=15 ! vpudec ! mfw_isink axis-left=0 axis-top=0 disp-width=1024 disp-height=768 sync=false

 

or

 

#export VSALPHA=1

gst-launch v4l2src device=/dev/video0 ! 'video/x-raw-yuv,format=(fourcc)YUY2,width=1280,height=720,framerate=10/1' ! mfw_isink axis-left=0 axis-top=0 disp-width=1024 disp-height=768 sync=false

 

 

However, the noise was not occurred with gstreamer-1.0.

Then, would you let me know how fix this noise issue with gstreamer-0.1 in L3.14.28?

 

 

Best Regards,

Satoshi Shimoda
