High cpu usage of compiz process while playback 4Kp60 h.265 video using nv3dsink

While playback 4Kp60 h.265 video using gst-launch with nv3dsink, the cpu usage for compiz process is very high and always over 90%.

The command is “gst-launch-1.0 filesrc location=Apink_MrChu.mp4 ! tsdemux ! h265parse ! nvv4l2decoder ! nv3dsink window-width=1280 window-height=720”

But if I use nvoverlysink, there is no such issue.

Is this issue the right behavior exptected?

Because of high cpu usage of compiz process, the video playback seems not fluent.

Hi,
Please run sudo jetson_clocks and share profile result of sudo tegrastats in the two cases. And release version($ head -1 /etc/nv_tegra_release).
We should see some GPU usage in using nv3dsink, but significant deviation in CPU usage seems not expected. Please help check with sudo tegrastats.

Hi,

Hi,
The CPU usage looks fine and does not go over 90%.
