Seeking Thumbnails (Projekktor Core)

Is there any way to incorporate seeking thumbnails like youtube and netflix have where when you drag the scrub bar, thumbnails appear above your slider to give you a peek into the video?

I actually just looked into that - looks you need to do a server side script that returns a thumbnail, since JS can't support video processing.

You would think this should be built into html5, Oh well. I guess I can live without it because my project is only going to be run locally :/

Thenior is (semi-) right. Common "search-nails" features are based upon a server-side processes. Its results are usually pumped into the players via async requests providing URLs to pre-processed thumbnails, setting them in relation to a given time index.

For sure it´s possible to achieve similar effects strictly on client side by creating thumbs via <canvas> and featuring a "preloading" <video>-element. Buts this is a hack and not covered by Projekktor´s "least common dominator"-principle.

To make long words short: Not yet.
