serviio 1.5.2 libmp3lame and could not lock user prefs

Hi,

I have an old serviio 1.4 server (with licence) and I try to update it bacause system is old too and updte is out of date. It is an opensuse 12.2 server and serviio works perfectly this server.

I installed a new opensuse 13.1 server and serviio 1.5.2 (on my test pc and old serviio works my old server) but serviio 1.5.2 doesn't work correctly. Serviio 1.5.2 can stream files to my Samsung TV and it can play files correctly but serviio mediabrowser can't play files on webbrowser. Error message:

200, Stream not found, NetStream.Play.StreamNotFound, clip: '[Clip]'http://192.168.1.2:23424/cds/resource/5/MEDIA_ITEM/FLV-0/MEDIUM?profile=flv_player&authToken=613f955b48...."

The problem same as in Chrome and Firefox webbrowser on linux and windows7 client.

I found these in serviio.log when I try to play file in mediabrowser:

I use ffmpeg version

and libmp3lame0 3.99.5 lame 3.99.5 libtwolame 0.3.13.

My old serviio 1.4.-2 on suse 12.2 can stream this file in mediabrowser... It use lame 0.9.2 libmp3lame0 3.99.5 libtwolame 0.3.13 and ffmpeg 2.3.3.

I don't understand this problem, can someone help me? Thanks.

I found that there are two problem.

First is an ACLs problem which solved by some google search. This problem is:

2015-06-22 13:37:59,957 WARN [prefs] Could not lock User prefs. Unix error code 2.
2015-06-22 13:37:59,957 WARN [prefs] Couldn't flush user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock.

I run serviio user serviio nad group serviio and serviio hesn't a home dir under /home. I would set serviio home dir to /usr/share/java/serviio when I created serviio user and group. It was the problem I need to create an serviio home dir under /home but not need to change JAVA_HOME=/usr/share/java/serviio. It solved this problem. Here is an same java problem which helped me: https://confluence.atlassian.com/displa ... ror+code+2

Second is an other problem but I can't solved yet. This problme is:

Problem is "Unknown encoder 'libmp3lame'". Symptome is thjat mediabrowser can't play any video stream from shared dir. But vlc or Samsung TVs can play video files from shared dir by DLNA.
I found this forum if some user updated ffmpeg the problem would be solved. But I use an fresh, updated ffmpeg and libmp3lame packages and ffmpeg translated by --enable-libmp3éame option.

But I think it isn't problem. ffmpeg can transcode files over DLNA for TV or vlc. I suspect the problem is flash transcoding because mediabrowser uses flash to play video stream and ffmpeg makes transcoding...

I don't know it is an flash player problem or other but flash player is up to date.

Can someone help me? Thanks.

SOLVED BOTH PROBLEM.

Second problem was "Unknown encoder 'libmp3lame' problem".

Cause:

I used two repo which included ffmpeg and its files... opensuse gemes repo and packman multimedia repo. When I updeted ffmpeg and its files last time the update was wrong. ffmpeg and ffmpeg lib files hadn't same version. I disabled games repo and updated files freom packmen repo and evrything works...

I recommend everybody don't use more than one repo...
