HTML video Scrubber

This repository contains and experimental HTML video scrubbar implementation which instead of placing video frames one by one until the scrubbar runs out of place slices the video into unit-sizes places and fill the scrubbar with the finest resolution possible preview.

The quest here is to explore how this looks, how useful or not it is and how helpful it might potentially be for viewing and editing user scenarios.

To-Do

Add a WebM version to support Safari which currently lacks VP9 support

Finalize the seeking filling version and add one for playing, too

Right now the seeking filling is like seeking but with the slice taken at the left edge instead of in the middle. It needs to be improved and maybe split into two variants: one which only draws the right side of the frame so it behaves the same way the seeking method does but gives more of a preview while being generated and another which draws the frame like the sliding one does, again just the portion to the right of the cursor, but the cursor pulses left to right based on the module, so I guess this might redraw already drawn parts to the left? We'll see, in any case, this will also give more preview while generating.

Ultimately this should be meaningless in case of offline generation (because the results is served finished anyway so preview while generating is useless), but it might be worth it for online generation and maybe the generated scrubbars will look better?
