Video stops playing mp4 (h.264), 1080p from Xiaomi Yi 4K+

Hi,

I have Xiaomi Yi 4K+ camera and recorded some video in 1080p. The camera records in mp4 - h264 codec. I have stored the video on the Synology NAS (model 214play), that is connected via Ethernet cable with Apple TV4.

When I play the video using the latest version of Infuse Pro - the video starts runs 3 seconds then stops with turning round for about 10 seconds then the video continues for maybe 15 seconds the it repeats.

Can you advice? I have tried to play the same video on iPad Air 2 via Infuse the same happens.

Would you be able to upload a sample video we can review here?
