Upload fail

[michaelboccara]

Describe the issue

I tried uploading a ~50MB mp4 file from a unity app and it fails after 10MB or so, resuming from the beginning and failing after 3 times

Steps to reproduce the problem

I actually have a test case which you can try from my forked branch:
https://github.com/michaelboccara/vimeo-unity-sdk/tree/feature/upload_fail
Open the Uploader.unity scene
Fill a valid local path to a >50MB mp4 file, and press the Upload button
The progress can be seen in the editor's inspector window

Unity version

2018.2 and further, till latest 2019.3

Operating system

Windows 10

I found a workaround for this problem:
I just reduced the chunk size from 128MB to 8MB! I noticed that the failure always happened after uploading ~10MB (out of the ~50MB of the video), Sounds like a bug in the server side. So by reducing the chunk to 8MB I'm avoiding the problem.
Still, would be nice to receive a sign of life from Vimeo to tell us what's wrong with their server.
