[YouTube-API] API response is status=400&error=FAILED after uploading a file unsing Zend _Gdata library

I use the code given in the API doc and Zend_Gdata to upload video with php.

No problem to get the "token" and to send the file to youtube, but a the end of the upload the 302 redirection gives "MyNextUrl"?status=400&error=FAILED

And I have no explaination.

Can someone help me ?
