public GCP Bucket

[dencoder]

Hi,

I have few mp4 videos that are stored in gcp bucket and I made them public for my use case. To verify that the video is accessible on internet, I tried to access one of them on a browser but what I got is blank screen (look at the screenshot below). 

To make sure the each file is made public or not, I added the allUsers permission to each video still same response. Is there any solution to resolve this?

Thank you!
