It's not currently possible. But I think this is a reasonable feature request. The steps to accomplish this are: 1. Add a `playing` `Bool` attribute to the python side https://github.com/jupyter-widgets/ipywidgets/blob/bd8ec4509cdfee0a3609b30a4bc9ea5e398b856b/ipywidgets/widgets/widget_media.py#L214-L217...

My sense is that the ability to start and stop playing is essential functionality for an `audio` widget. So if ipywidgets is going to provide an audio widget it is...

The other issue with ipywebrtc is that it seems to currently only support jlab-1 https://github.com/maartenbreddels/ipywebrtc/pull/95

One complication is how to deal with difference between erasing and drawing paths. Would probalby have to return something like `{"drawing": [path, path, path....], "erasing": [path, path, path]}` how's that...

> But in the end the interesting output are just the coordinates of the final roi that one has drawn. So you basically want the outline of a mask? Can...

Just to disambiguate: When you say path coordinates, do you mean the sort of sum of paths, or all the individual paths that were used to create the masks? For...

I guess my thought is that that is really two different red lines. Also how did you generate the red line, programaticcaly from verts? If there is an easy way...

I thought about this a bit more and while there is a [`make_compount_path`](https://matplotlib.org/stable/api/path_api.html#matplotlib.path.Path.make_compound_path) function that only works for purely additive paths, since this allows erasing I don't think there's a...

Apparently I started the process back in march and it never got through: https://github.com/conda-forge/staged-recipes/pull/18223 I think i'll reopen and ping. Thanks!

Ah it looks as though the build failed and I didn't know why. If it fails again I'm now even further removed from understanding building pyhton x typescript packages so...
