Hi Ryan,

This is really a great example for upload large video with in chunks. But the problems we faced is, when we start for uploading video the videos chunks size is not picked by upload process partSize. Browser by default pick less that 1 mb size for video chunks. How we resolve that issue.

hi @harmeetsign0013,
sorry for the late reply, I must have missed this in my GitHub notifications.

Could you post a small sample of your code and what's going on, have you tried increasing the "partSize" parameter in the code above to something over 10mb?

Hey how would you tackle hiding the access and secret access keys?

@andrewhyeung were you able to figure out hiding the access and secret key? How can it be done.
