HI @lucio.schioppo and Welcome to the Toradex Community!

Which Display on which interface are you using?
Could you share the dmesg.log?

Do you see the flickering also when you don’t run any video?

Best regards,
Jaski

Hi,
i’m using the capacitive Touch Display 10.1" LVDS.

The flickering is only when i try to run videos with the Qt MediaPlayer example, it’s seems like a codec error. I have try different .mp4 file but nothing change.

thanks
Lucio

Dear @lucio.schioppo

Unfortunately this is a know issue at the moment on boot2qt. We hope it will be fixed when they switch to a newer version of the BSP. Currently the only option is to switch to software rendering by deleting the v4l2 gstreamer plugin. The following should work:

find /usr/lib/* -name "libv4l2*" -delete

I have try the command “find /usr/lib/* -name “libv4l2*” -delete” but in all directory libv4l2 not exists.

I use the B2Qt 5.14.2.

Hi @lucio.schioppo

Sorry, I mentioned the wrong filename… You can delete /usr/lib/gstreamer-1.0/libgstvideo4linux2.so that should be the correct one. After that it should fallback to software decoding.
