So I recently had some issue with some 720p videos and I couldn’t fix the issue
Basically I’ve some little jerk playback (a very little short struttering every X seconds ) and I don’t understand the reason. It happens only with some videos and only on my android tv. On web app (chrome), desktop app, ipad app, iphone app, everything works fine and smooth. Other videos too on android tv work well.
Everything is direct streamed, 0 transcoding, all with Ethernet, no wifi, no lag, just this little jerky playback.
I tried basically every options in setup but nothing works.
I have 3 Android TV, same model but 55/50 and 43", and it happens on every tv but not on other devices.
Any idea?

EDIT: I added the log, just ran the video for 1 minute, the little stuttering is always present every X seconds for a little time frame. BTW it’s not just this video, the entire catalog for this tv show is the same and the same problem is another tv show catalog (1080p videos this time)
EDIT2: Added a sample too (I hope you can download it)
