Re: [Matterhorn-users] Uploaded videos failing on "inspection"

Tue, 10 May 2011 03:30:15 -0700 

Hi Sean,
the problem with the path is well known and for a strange reason the settings from .bashrc are not evaluated in RHEL/CENTOS 5 (unlike Ubuntu). That's why you can set the path to the third-party tools in the config file (config.properties). At the end of the file you can uncomment the path-property for ffmpeg, ocropus, mediainfo and the qt subtitle embedder. 


Maybe there are some more paths in $FELIX_HOME/config/services/ that 
have to be included, like tesseract in the textextractor config, and 
mediainfo again in the inspection config. I don't know why we have this 
included several times and which file is the source of authority...


Good Luck
Rüdiger

3rd party tools are installed. I logged in as the user 'matterhorn' to 
see if it could run mediainfo. It worked fine. I ran it against an 
mpeg video I uploaded and it gave back lots of good information about 
the video.

("mediainfo -f sample_300kbit.mp4")


I tried running Matterhorn as user root, (also as a service). I got 
the same errors. I tried running Matterhorn as user root in the 
foreground, (i.e. using 'sh 
/opt/matterhorn/felix/bin/start_matterhorn.sh' in a terminal window.) 
That worked fine; I was able to upload a video and view it after 
processing. I tried running Matterhorn as the user 'matterhorn' in the 
foreground. That also worked fine.



I am assuming that running Matterhorn as a service, (RHEL-5), does not 
execute the same '.bashrc' and/or /etc/profile.d environment setup 
files as get run when you login interactively. This would cause it to 
not find mediainfo in /usr/local/bin. (And possibly other 3rd party 
tools.)



I should be able to modify the 'matterhorn' init.d script to include 
those environment setup files. I'll give that a try later this week 
and let you know how it goes.



Thanks for all your help. I now have a working Matterhorn running in a 
terminal window.


Peace,
Sean

Right, it looks like the user running Matterhorn can not execute
mediainfo.  That's usually due to one of three things:

1) Path: the user running Matterhorn does not have the mediainfo binary
on their path.
2) Permissions: the user running Matterhorn can't execute mediainfo
3) Installation: the 3rd party tools were not installed

Are any of these true for your installation?

    Hi Sean,
    If you call mediainfo directly against a video, does it work?

        I have a brand new install of Matterhorn 1.1.0 on Redhat 5,

        uplaoding mpeg and quicktime videos with the same errors.
        Matterhorn is running as a service as the user 'matterhorn'. The
        /opt/matterhorn tree is owned by matterhorn and all writeable.
        The install says everything built successfully.

        Does it look like I configured something wrong, or is this a
        possible bug?

        Here are the errors I am getting:
