Video content-type not set to video/mp4 results in black frame

[dustinkerstein]

If I upload to my dash fragmented h264 mp4 files to an S3 bucket using the Amazon web-based uploader, the videos play fine when directly loaded in Mobile Safari (iOS 10.0.1), but if I try to play them using my three.js viewer then I just get a black screen. However, if I upload to the S3 bucket with Cyberduck, they play fine directly in Mobile Safari and in three.js.

It looks like Cyberduck is setting the meta-data 'Content-Type=video/mp4' and the AWS uploader is 'Content-Type=application/octet-stream'. When I manually set this meta-data to video/mp4 everything works correctly.

I originally posted this to #9754 but it appears to be a different issue.

Thanks,
Dustin

I don't think there is much we can do about it?

Ok. I'll just make sure to set this correctly. Just figured it'd be good to bring up just in case anyone else ran into the same issue.
