InvalidMediaFormatException

Hi, I use serviio to transcode the TV channes from a VBOX DTV with a plugin that I did.
It worked very well for all the channel on V 1.8 and 1.7.1 but with 1.9, there is one channel (out of 34) that gives an error.

WARN [FeedUpdaterWorker] Failed to retrieve online item information for http://192.168.5.100:55555/PARAMOUNT%20CHANNEL. It might not play.

I executed ffmpeg -i "http://192.168.5.100:55555/PARAMOUNT%20CHANNEL" and this is the output:

Any idea of why this is happening with version 1.9 and not with previous ones? I use it on a Synology nas (broadwell architecture)

There is new ffmpeg with 1.9 maybe it sends something the server doesn't like and returns 500 error. Or it can just be temporary error on their side. Does the url work in VLC?
