Hello, I'm doing some mods to the player and now I need also to put in some metadata...
For example I have to put the title of the video, keywords and duration.
I've tried to add for example the variable for the title as below in player.inc:

Code:
so.addVariable("title","{$video_info.title}");
But it wont work giving this error: Parse error: syntax error, unexpected '.', expecting '}' . Is obviously a syntax error...

So my question for Admin or anyone else who can help here is:
What is the syntax $variable for VIDEO TITLE, VIDEO CATEGORY, VIDEO KEYWORDS, VIDEO DURATION IN SECONDS to be included as "so.addVariable etc etc" in player.inc?
Thank you in advance for your help.
