Decoding video with mpp, and showing NOT in fullscreen

[nikitos1550]

Hello!

I have rk3328 system, I built all related sources from rockchip-linux repos, rockchip kernel. I can decode video via gst-launch-1.0 util using kmssink (my system is without X/Wayland). But video is overlaying in fullscreen mode.

What is proper way to scale video to some smaller size and show on the part of screen? Also I built rk-qt-video repo and testing player example, that somehow suppose to show video as I want. But it is not working properly.

# ./player /root/test2.mp4

Video is not playing, I can see only first frame in all combinations FullScreen EGL/DRM or not FullScreen EGL/DRM modes.

I also built Xserver with armsoc, and QT5 with xcb support. Player demo now working, but video can be show only in fullscreen mode, if not fullscreen that black square on video place. Sametime if I will start gst-launch with rkximagesink it can be resized as window and moved (very slow).

Ask rk-qt-video, not here.
