I use server to stream recorder videos on Android phones and play them in Android app later. However I noticed that I am not able to play all videos, I used ffmpeg to see if there is any difference in recorded videos and where the issue might be. That is an example of loading and playing video:

I cannot see any difference in the videos characteristics. Both are baseline H.264. Both videos are playing in chrome when I access them via direct links, the problem is on android versions 6, 7, 8. There is strange thing because when I downloaded that not loading video directly and put in the android app to raw folder and played it directly everything worked perfectly. I checked if the problem was bandwidth, so I uploaded bigger video about 12Mbs, mp4 as well H.264 Main and then streamed it to the app and it worked like a charm. So I suspect that the issue might be with recording bigger files within my android app. To stream video I only use MediaPlayer.
That is an example of the video I uploaded and later streamed:

Is there any chance that my hosting provider uses some kind of software that can manipulate data that is on the server?
I also check manually other videos from different websites by inserting links manually in the code to check if MediaPlayer works correctly and every video was playing.
