Summary: The Teradek VidiU gives you the freedom to broadcast live
high definition video directly to the Web without a PC. Whether you're
streaming out of a video switcher or wirelessly from your camera,
VidiU allows you to go live when you want, where you want. VidiU
offers API level integration with the Ustream, YouTube Live and
Livestream platforms, which makes streaming to your channel as
easy as logging into your account.

stream disclosure when snapshot.cgi script is called.

/tmp/jpeg
/tmp/jpeg/snapshot.tmp
/tmp/jpeg/snapshot.jpg
%ld byte snapshot received and saved at %s
{"result":"success","size":%ld,"file":"%s"}
/home/www/snapshot.jpg
