Display dynamically changing data like a video

Hi,

I wonder if it is possible to render a video in a bokeh-server. The video would in fact be a list of numpy arrays.

I successuflly used a bokeh-server with widgets to update a plot and the notebook integration to display one image stored in a numpy array.

I guess it would be fairly easy to adapt this example to display one frame of the video by interacting with a slider but how could one add a “play” button widget

that would make the video play automatically? Is there anyway to schedule an event to occur at some period? Would using a AjaxDataSource be the way to go?

Thanks

Guillaume
