kats, can you give us an overview on this idea? Thanks!

I'm talking about a region on the minimap canvas, showing the current visible portion of the waveform from the main canvas.

Something like this:

Seems you can integrate the ideas from peak.js. :)

If you use that kind of scroll, I think that the problems with spectogram visualization and minPxPerSec will end.

I did that!

Take a look:

https://github.com/drount/wavesurfer.js/tree/wavescroll

It's the wavescroll plugin.

I'm using a pretty outdated version of the wavesurfer code though.

Awesome, drount! Note for developers: copy this function to your wavesurfer.js file. Now, we need to implement the relation between zoom factor and width, I guess.

EDIT: there seems to be a conflict between regions plugin and the "selectionForeground" parameter you used in your fork examples, @drount

Thanks @drount!

I'm not going to replace the default scrollbar with the mini-map plugin just yet. What I'd like to do now is just add an overlay, corresponding to the visible area of the main waveform, to the mini-map.

[drount]

@echo66 Yeah, unfortunately as I said, the plugin is developed in an really old version and I do not have the time to keep on with the main repository changes (that changes a lot!)

Actually I didn't even know that the region code that I wrote was extracted as a plugin :P

Any updates on this? I notice showOverview:true, but it doesn't seem to work. It surrounds the entire minimap with a green box.
