Precondition Failed

Precondition Failed

I got this Error 412: Precondition Failed on Thursday as I was setting up Quicktime Broadcaster. Error 412 occurs when the data stream sent by the client included a ‘Precondition’ specification which the server detected was not met.

It was such an unusual error that it has never occured while the two QT masters before me were in charge of streaming. What could be wrong? I was just testing it a day before, the only difference is i performed software update on the client (the Powerbook) on Wednesday night. And now it ain’t working, as I was about to do on-site testing at CMC.

Anyway, many thanks to the two guys who helped me eliminate the possible causes one by one. We tried everything from changing the iSight and firewire cable on the client to trying out two other clients (another Powerbook and a G5), exchanging cables and cameras in the process. All setup have same iTunes version (updated on Wednesday night). If iTunes has anything to do with the problem, i doubt but I wouldn’t know for sure. In the end, we opted to update the server. An update was available perhaps the same time the client was updated. The update was too big that it consumed the entire afternoon.

Everything was back to normal the next day.

The 30-minute CMC’s UP TV Online Launch on Monday afternoon with the assistance of the UP Computer Center was a success. #:-s
