Process ffmpeg has a return code of 1! - Ubuntu

Hi,

Every time I try and play any video, it just sits there with the loading icon.I checked the log and It's put me at a dead end since all I got was this;

  Code:

2014-06-22 11:23:21,250 WARN  [ServiioStatusService] IOException occured. Returning error code 500 to the REST layer. Message: Transcoded file '/tmp/Serviio/transcoding-temp-960-flv_player-ORIGINAL.stf' cannot be found, FFmpeg execution probably failed
2014-06-22 11:23:21,654 WARN  [ProcessExecutor] Process ffmpeg has a return code of 1! This is a possible error. Detailed output follows.

The Web UI doesn't throw an error either when i'm trying to play it. I had a feeling it might be something to do with the presets but I don't want to modify anything in-case it makes it worse.

I followed this tutorial.

Any ideas?

Thanks.

You're using an old version of ffmpeg, you'll have to build your own. There are some tutorials on the wiki or ffmpeg website.
