I want to create a script which will be importing videos from other sources, categorizing them (like title, description, category, tags) and displaying them on a site. As far as I understand this will be working with Linux cron... I know that there is encoding and there can be more aspects of this that I am not familiar with. Would you be able to tell me at what specifically would I need to look and get familiar with prior to working with this (like sections of php.net, other sources, anything). Basically all the elements and the info that I would need in order to get this done (in the best possible way as of now).
