You may be getting this error if you are trying to playback a file that has H.264 video but in a.flv container, where as the file isn’t an mp4 file. Try using flv:someFile.flv Note: .flv is not supported on iOS or Silverlight light clients. Salvadore ---

Yes, the default prefix has changed to “mp4:”, but you can revert in the Wowza Manager \> Server Setup \> Basic tab \> "Default Stream Prefix ". Change that to “flv” and re-start the server. Richard ---

I had a similar problem and only discovered it after encoding nearly 2000 videos. Instead of starting over, I used this command to insert the moov atom: [HTML]/usr/bin/ffmpeg -i ./input.mp4 -c:v copy -movflags faststart -strict -2 ./output.mp4[/HTML] In actuality I had a different source and destination directory and so was able to batch the whole thing at once keeping same filenames. ---

Our files are h.264 within FLV. Is this change a new requirement for 4.x as these files play back fine in 3.x without the flv: prepended. We only use these streams within a flash player using FLVPlayback and don’t stream them to iOS. ---

Hi Viktor, you can change this back to .flv in the [install-dir]/conf/Server.xml file, under / Also, please see this comment regarding the [admin.password issue](https://www.wowza.com/forums/showthread.php?36205-WowzaStreamingEngine-Manager-user-password-problem&p=136379#post136379) Salvadore ---

Hello mkauzlar, and welcome to the Wowza support forum. I am sorry, but as far as I am aware, there is no way to use different default prefixes as you are describing. Kind regards, Salvadore ---

Hello! Can I reach this “Default Stream Prefix” property from config files? I mean without the Manager app? I having problems with the Manager application. (It does not accept user/pass for some reason) Thanks Viktor ---
