You can upload files to the same place people upload video clips for VDPAU testing:
* sftp/scp to partners.ftp.nvidia.com
* ftps to partners.ftp.nvidia.com (port 21 for explicit AUTH TLS, port 990 for implicit FTP over SSL)
(requires in-browser Java support)
In all cases, user ID is vdpau with no password (i.e. empty/blank). Simply upload files to whatever directory the system places you into. You will be able to upload files, and possibly list files, but not download files.
