I want mirroring my tablet screen with projector while recording my screen. Is this possible?

[Android Central Question]

HELLO TO EVERYONE

I have P580 (Samsung TabA6 With Spen)

I want mirroring my tablet screen with projector while recording my screen. I can not use both of them at the same time. Smartview shut down when i started record my screen so i tried that:
first step started screen recorder
second step started mirroring

Everything seemed good; no error no shut down

I recorded my screen for 30 min. I wacthed the video and *i saw sadly that the video froze after starting the screen recording* and video file has only voice.

I used this system with N8005 (samsung galaxy note 10.1 with android 4.4.2) and tab3 (with andoid 4.2.2) but i can't use this android 6 and adroid 7 devices

What can i do ?
Is root be a solve for this problem? if your answer is yes, how can i do?

Thank you very very much...

Where are you mirroring to? When I mirror to a PC, I just use Sidesync to mirror, then enable Gamebar on Sidesync (It's a Win10 feature, press Win+G), and set it to record.
