Video tag only playing audio


I am developing an app that records and stores videos,
I already did the recording videos part, but when I try to display them it only plays the audio, not the video

Also, i can’t use the stream media plugin because I want to put some buttons so the user can pause, play, go frame by frame, etc.

I tested it a bit, and I found out that it happens on my Android tablet (Android 8), while on my smartphone (Android 7) there is no problem. Also I found out that on my tablet if the video size is less than 1 MB it plays the video without problems.

I have tried to install crosswalk and also use Videogular without any results.

Any idea? I paste the code for the video part:

<video #myvideo controls preload=“metadata” webkit-playsinline=“webkit-playsinline”>
