Mass converting Movie files to FLV

I've spent some time writing a script to convert all the MovieItem files in a gallery to FLV files.

The code looks for a file (in the same directory as it) called "filelist.txt", which is a list of filenames of the movie files you wish to convert (relative to the base of your albums directory). E.g:

album1/foo/file.mov
album2/foo/file.avi

The script handles the conversion, backs up the movie file, and does all the operations needed for gallery to become aware of the changes.

Steps for use:
1) Create your filelist.txt
2) Place in your gallery root folder, make sure debug mode is enabled ($debug = true below), and run via your browser.
3) If everything looks good, set $debug = false and $onlyconvert = true, fire up a terminal and run "php flv_convert_script.php". This will take a while and assumes you have ffmpeg-with-lame set up correctly. You should get a progress bar from ffmpeg.
4) If everything worked, set $debug = false, $onlyconvert = false and run the script with your browser again. You should now confirm that the process worked correctly by viewing the FLV file through your gallery - note the template/database cache will need to be emptied first.
5) If you're sure everything has gone according to plan, set $debug = false and $cleanup = true to delete all the .bak files, and you're done!

Good luck.

It looks like you don't have LAME support enabled. You'll need to recompile ffmpeg to include the lame library - there's plenty of help on google if you're running a standard setup, if you're not it is quite tricky unfortunately.

Re the chmod, that's the way your folder permissions are set up. You can use /lib/support/ to change it to group writeable.

Hi again,

Does it matter whether I use php4 or php5 to run this script?
Also, is there any difference running it through the browser, or can I just use the shell for all of it?
It looks like the the browser just formats the output of the script.

Thanks!
