Unable to play videos through qtmultimedia using gstreamer-1.0 for imx6 by yocto build image. Showing No m_videoSink available!

[madhureddy]

Hello All,

I am unable to play videos through qtmultimedia gstreamer-1.0 for imx6.

meta-qt5: dizzy

from HMI, i am trying to play video, it showing the below message.

root@nitrogen6x:~# ./HMI_IVI_APP_2.2/HMI_IVI_APP/HMI_IVI_APP --platform eglfs &

[1] 318

root@nitrogen6x:~# QEglFSImx6Hooks will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.

If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1

Unable to query physical screen size, defaulting to 100 dpi.

To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).

Hi Madhu,

I looks like the QtMultimedia component doesn't really take eglfs into account:

[Development]  The dark side of QtMultimedia - strikes back

Maybe you can try modifying the component to force the use of the video sink of your choice.

Also, another test would be to make sure a camerabin pipeline works fine:

$  gst-launch-1.0 camerabin

Regards,

Gary
