[YouTube-API] Re: cURL Upload to YouTube API

Hello,

We don't have any specific documentation on how to use cURL to
perform an upload because we don't recommend doing that. You can use
the Zend GData client library for performing uploads from PHP:

https://developers.google.com/youtube/2.0/developers_guide_php

If you'd prefer not to do that, it's certainly possible to get this
to work, but debugging your particular issue is up to you. The entire
direct upload flow is documented at a protocol level at

https://developers.google.com/youtube/2.0/developers_guide_protocol_direct_uploading

so debugging your issue is a matter of looking at the traffic you're
sending (either in a log or using Wireshark/Fiddler) and comparing it
to what we say you should be sending, and figuring out what's
different.

Cheers,
