I want to allow visitors to upload their youtube videos on some of my site pages and have it look like thumbnails or a "wall of TVs" on my pages.

Youtube told me: YouTube Direct aggregates videos in playlists, so for display purposes on your site, you'd want to either embed the standard playlist player (which is the easiest approach) or write some custom code to parse the playlist in question and display the videos in it in some other fashion.

Anyone know what type of "custom code" I'd be writing for this? I may hire a coder so what type of code would I be asking them for? Thanks.
