Hi
Hi there
I encounters a confusing problem that the *.rm/rmvb video files can not be trackered by the following SQL
Not SQL, SPARQL :)
"SELECT nie:url(nie:isStoredAs(?video)) WHERE{?video a nmm:Video}";
You don't need the isStoredAs here, all you need is
SELECT nie:url(?file) WHERE {?file a nmm:Video}
I analysed the /usr/share/mime/packages/freedesktop.org.xmlthat the mime type [<mime-type type="application/vnd.rn-realmedia">]isdefined.
Tracker has to be configured with --enable-gstreamer-helix I guess, or else gstreamer has to have some plugins installed to "understand" this format.Can you please run /usr/libexec/tracker-extract -f on your video file and
paste the output somewhere?
Also,I found only video/* mime type is trackered in tracker-extract-gstreamer.c,is that right?
It is right
Uuuuh, serious spaghetti mixing here :) qttracker is a library to access Tracker from Qt applications. It is now deprecated in favor of libqtsparql.So,does the qttracker only tracker video files which obtain mime type[video/*]?
The video files will get their metadata extracted if gstreamer can get any metadata. If it can't (because it has no module installed for a specific
format), then no metadata will be extracted.
Please check if you have gstreamer modules for that format, and also paste the output of tracker-extract somewhere as suggested above. You can alsoCan anyone give me some suggestion?
try the gstreamer-helix ./configure option. Cheers Adrien
