Only Black screen when running bodytracking

Hello.
I’m trying to work with body tracking on Linux arm64 platform and Ubuntu18.04.
when I try to run SimpleBodyViewer-SFML it shows only a BLACK screen and nothing else. And the BodyReaderPoll also doesn’t show any results, it just freezes.
I followed some advice by other repos and installed libpng12.so. ,however, it doesn’t help. Then I changed the astra.omel from debug to error, only found that every plugin loaded well, including libOrbbecBodyTracking.so.
Could anyone please give me some suggestions? Thank you!
