Dear All,

When i use "gst-launch-1.0 uridecodebin uri=file:///usr/local/4k.mp4  ! rkximagesink", there is no any 4K video problem but there is no sound. I also try it with FHD video and saw there is no sound.I try to use qt5 videowidget example by setting export QT_GSTREAMER_WIDGET_VIDEOSINK=rkximagesink
export QT_GSTREAMER_WINDOW_VIDEOSINK=rkximagesink, and play the same video, play video andsound then frezee all. I tried same 4K video with mplayer and sound and video not smooth freeze then play and loop in same state. But if I use FHD video with mplayer, sound and video is ok. So how can i solve 4K video and sound problem. Pls help!!!!!!
