What is error -5?

[Ian Davidson]

Hi Sebastian,

Shortly after my first posting, I realised that I needed to process the 
media and that could have been the cause of my error - so I tried again 
(2nd post) using decodebin.  If I did not have any logging I could see a 
message 'Redistribute latency' and if I turned on the logging I got 
continual error messages being logged 'Reached libmpeg2 invalid state'.

I know that the original file can't be too bad since playbin manages to 
get it to work - so what am I missing?
