[Solved] MediaBrowser not play

Hello!
Sorry for my English, is translated by google.
I have omv 1.12 Kralizec, I installed the plugin Media Browser Server, everything perfect, I configured the library, with several folders (movies,videos home, music and photos), I have all the movies with their covers and synopsis, but here comes the problem, photos I see perfectly in my SmarTV and web client media browser, but movies and music gives me error "there was an error when playing video", however the photos I can see them perfectly into the pc and my SmarTV .
I have a Samsung SmartTV which I installed the app MediaBrowser, but not by the DLNA app or only see the covers and synopsis of the film. "DLNA tells me to check my network".
For now I see films by minidlna plugin.
I have a log file...on lines 39-48 I have seen this error:

Thank you!!!

In the web client pc black screen when playing the movie stays, if you try to move the movie shows the error.
In the SmartTV when you try to play the movie you get the error.

result omv-showkey mediabrowser:
root@nas:~# omv-showkey mediabrowser
<mediabrowser>
<enable>1</enable>
<mediabrowser>

I've attached two pictures of when it leaves the error.

I have applied and still the same, I cleaned the browser and nothing!
I installed a version for testing in windows media disk accessing openmediavault and works perfectly. It is as if MediaBrowser could not access the library to play the movie. MediaBrowser in windows media info shows me all the information:

I finally solved !!!
I have done these steps:
apt-get install w32codecs
apt-get install mplayer mencoder ffmpeg flvtool2

and "deb-multimedia-keyring" was installed

But in my Samsung smart TV app I get the not watch movies, I still leaving the message "Unable to play None of the mediasources are playable"
I deleted the app from Samsung and reinstalled the app, and all resolved. I see the movies in my SmartTV.
Nothing like being stubborn and not give up !!!
Thank you!!!
