Hi All ,
I have built yocto image with

DISTRO_FEATURE_remove = " x11 wayland"

gstreamer1.0 support for QT5.5 for imx6q board from freescale.

Kernel version built is 3.10.17

Platform EGLFS


I tried to run the example applications from QT5.5 such as QMLvideo from multimedia and it plays video smoothly without any delays.


but when i try to play video with videowidget from multimediawidgets example then i get a Warning: "A lot of buffers are being dropped."


This occurs only when i try to play mp4 video 1280x720, 1080x720 any video with higher pixel size.

and when i play video with lesser video image size it plays ok for example video with 360x240.


Note: videosink used above is qgstvideorenderersink.


Also, i would like to point out that the same video with 1280x720 plays well when i play it with gstreamer 1.0 with the following command


gst-launch-1.0 playbin uri=file:///home/root/mini.mp4


Any help or pointers related to this issue will be helpful!


Thanks & Regards
