imx8 QT wayland video

[songhongliang]

hi,

I use systemctl stop weston@root.service cmd，stop weston service.

then，

/unit_tests/V4L2/mx8_v4l2_cap_drm.out -cam 1 -d "/dev/video1" -fmt UYVY

can Display the camera screen，

but，Cannot display normally when using QT application。It seems that under wayland, video data cannot be read normally。The version of L5.4.47 is relatively new, can you give me some help.

Thanks

tried the "qmlglsrccamera", "test_qmlglsink", "test_qmlglsrc" under path "/usr/share/qt5/examples/multimedia/qmlgltest", and they are all OK to display on the Weston, with LVDS to HDMI output.I used xwayland

HI,

I mean "qmlglsrccamera", "test_qmlglsink", "test_qmlglsrc" ， source code，

I am not very familiar with gstreamer yet, I need to refer to some

[songhongliang]

after building, you need download images to the board, you can find it after board boot up

[songhongliang]

HI,

I know，I found these files in the directory of the board, but I want to find the corresponding source code

Thanks

[joanxie]

maybe you can refer to the source code from path:

"/imx-yocto-bsp/build-xwayland/tmp/work/aarch64-poky-linux/qtmultimedia/5.15.0+gitAUTOINC+040378a91f-r0/git/examples/multimedia/"

Hello,

Were you ever able to find the source code for this example? I have only been able to find the binaries myself. 

Thanks!
