Can't read recorded videos from the mobile app

[rezzalex]

The recorded videos are not played , the screen remains black.
To be noted, my videos are a bit transformed , by including the sound recording in it, but still in a .mp4 extension.

They can be played perfectly from any other device/app

Hi.

Could you possibly send me a video sample?

Even though your videos are bit transformed, does the URL remain same?
