Problem playing videos on Raspien

[fatcat46]

I just installed subsonic on ,y raspberry pi. I can play music but not video's. I get video not found or access denied errors. Here is what the log shows:

[2015-04-13 12:12:35,141] WARN StreamController - Unknown duration for OLd Movies 1946 Fran thru 1969-2. Unable to estimate transcoded size.

I am running subsonic version: 5.2.1 (build 4428) – March 4, 2015

i am not good ad linux so any detailed instructions to fix this will be greatly appreciated.


more info:

I use subsonic in my firefox browser to play music on a windows7 64bit machine to listen to my music and also Isub on my iphone 6+
Hardware is raspberry PI2
Version 5.2.1 (build 4428) – March 4, 2015
Server jetty-6.1.x, java 1.7.0_75, Linux (60.8 MB / 118.3

I don't know how to get the following info from the PI:

Java Memory Limit:
Problem Filename:
Output from ffmpeg -i: (If you open a command prompt and type 'ffmpeg -i <filename>' what is the output? Ideally put this in a "code" block)


Thanks
