About Metadata

[golgoj4]

Hello All,

If your interested in compiling or just checking out the code (warning - im very new to c++) it can be found @ http://gitorious.org/linuxmce-autotagger. Whenever i push it to the server, it should be able to compile and run. There is also a binary called 'autotagger' that should be ready to go stand alone.

Beta version 1.1
-Takes 2 different command line arguments:
    -The path in quotes "/home/public/data/videos/test/"
    -The file number of the directory. This can be located in mediaFilesSync in the webadmin. Whenever you mouse over a link to a file, it shows you the file number (as its part of the link)

Test if you have a chance on a smaller media set (or large if your brave). In my testing the biggest impact is sustained db activity over %50 while running over larger lists of files. And this is the reason its specifically NOT recursive. So wherever you direct it, files should be there and not in a subdir.


Thanks for taking the time to read and test. Hopefully this can be integrated in the near future so our media will get tagged automagically.

Metadata can be stored either internally, in the same file as the data, or externally, in a separate file. Metadata that is embedded with content is called embedded metadata. A data repository typically stores the metadata detached from the data.

spam... :/

[golgoj4]

problem has been solved.

Any brave souls are welcome to test it out.

By default it finds /home/public/videos and looks there for files.
You can direct it to another directory by entering the path , but as this is testing i recommend a small set of files.

On to updateMedia...

If I point it at a specific directory I get this:

Media Autotagger v1.1
./autotagger: symbol lookup error: ./autotagger: undefined symbol: _ZN9QListData11detach_growEPii


If I run it with no parameters I get the following output, autotagger immediately exits:

in my late night brilliance, i failed to test it with all path types. I just noticed it chokes on certain kinds. Trying to enter my own custom path errors out on some (specifically with spaces)...do'h! Do you have any videos in /home/public/data/videos? It may immediatly exit because it doesn't find any there.

[golgoj4]

updated it, fixed the issue. When passing command line arguments, they need to be quoted i.e. "/home/public/data/videos/Hard Drive 1 [47]/tV/BSG"

Sorry for the mistake before

In /home/public/data/videos is the automatic LinuxMCE symlink to my Windows Share and a directory named 'test' that I've stuffed some movies and tv shows into.

If it gets to the windows share it'll find thousands of files to churn on but I don't think it followed the symlink to the windows share.

I get the exact same results with the updated version.

Its set to not follow symlinks because in case of lots of files, it can eat a lot of cpu while it churns through them. I know this is going to sound silly, but did you enclose the directory in quotes? "/home/public/data/videos/test"

Thanks for your time and patience in testing my 1st c++ program.

Hey golgo,

Yes I did enclose them in quotes.  There appeared to be no difference either way (unless there is a space of course).  I updated to your latest git version with a 'git pull' just a few minutes ago and tried again.

With no arguments it is happy but quits immediately without going into any sub-directories (there are 2, one real and one is an lmce symlink to my NAS share), and it is correct in that there are 0 actual media files in this directory.

If I add a trailing '/' to any directory location it is 'Not Found in DB', if I do not include the trailing '/' it is happy but doesn't process any files (see above).  This is the case for any directory name I provide it.

Anyways, those are my results so far.  Let me know if you want me to try anything specific.

Hmm:

I don't seem to have this lib.  Likely the symbol problem.  I'll have to try to locate it.

It appears im doing something very wrong. I noticed that in that cases where it locks onto the proper directory its going dead immediately.

Did you build and run it locally with the qt sdk?


-golgoj4

[phenigma]

I have been using the binary in git so far.  The library is not an issue, apparently it's a special library file of some sort that doesn't have an actual file.  Hmm, if I get time I'll try to build it.

Nah no need to, i was just wondering because someone else had a completly different error. Ill need to check further to see what im doing wrong.

[golgoj4]

if any experienced dev's want to jump in here...im curious as to how i should plan to deploy this? statically linked? dynamic? Im throwing these words around but I barely know what they mean. The one currently compiled is a 'shared' version i believe. Im trying to make a static version to help with testing. Is this a bad idea for any reason.
