Hi, i'm trying to play external videos using netStream.

My script work fine with .flv files, but with .f4v it doesn't work with Firefox (i've tried versions 3.6 and 4): I get NetStream.Play.FileStructureInvalid

F4v files was exported using Media Encoder from Premiere.

Here's a part of my code:

ncConnection = new NetConnection();
ncConnection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
ncConnection.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);

ncConnection.connect(null);

nsStream = new NetStream(ncConnection);
nsStream.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
nsStream.client = this;
nsStream.bufferTime = BUFFER_TIME;

nsStream.play("http://www.domain.com/myVideo.f4v");

Does anybody know what causes this problem?

Thank you!

By the way, there are massive numbers of problems with Flash 10.1 and 10.2 (especially) and Firefox 4. Also, I have observed a lot of problems with Firefox 3.6 and Flash 10.2.

Some developers point to video playback problems in Firefox 4 and Flash 10.2.

With that said, my previous post still stands - I was able to play your video on Firefox 4, Flash 10.2 form a different server.

This most probably means that f4v file is not encoded with a supported codec and file container has a structure that is not recognized by Flash player. If you have access to this asset - try to reencode it again.

File extension doesn't really matter as long as file structure itself is conforming to specs.

Just tested this file in local environment and on another server - it plays perfectly in FF. I believe there may be server side issues (headers, permissions, etc.) that prevent this asset from playing in Flash.

Interestingly enough it plays in QuickTime in FF.
