General Question: Audio player widget

[ThetomekK]

Hi there,

Do you think, it is possible to implement a kind of audio player widget for panel?

I'm looking for a possibility to show the audio raw data and/or the spectrogram (2D numpy array) and play the underlying audio.

Thanks for your opinions.

I don't see why not, I'd happily accept a PR adding one. Should be easy to add a model which renders an audio HTML tag and populates it with base64 encoded data or a URL pointing to a remote audio file. If you feel up to working on this I'm happy to provide pointers, something like FileInput model would be a reasonable starting point.

If we're adding an AudioWidget we might as well add a VideoWidget too.

I already demonstrated video working via YouTube, which was trivial, but I can't remember what I did with that example. I think it was based on something like https://stackoverflow.com/questions/27315161/displaying-a-youtube-clip-in-python .

That's not really what I was talking about, I was imagining a dedicated widget which you could point to a local or remote mp4/webm/... file. You could probably already to this using a Div but a dedicated widget seems sensible so you can more easily embed it and so a user does not need to know too much about HTML.

Sure. For audio there's not really an obvious YouTube equivalent, but it would be nice to have examples of both types (local media player, and embedding remote content like YouTube).

[philippjfr]

Sure, a simple wrapper around YouTube videos makes sense too and wouldn't need a custom bokeh model either.

Documentation: show an "intro to holoviews talk", e.g., from one of the conferences you presented at :-)

@ThetomekK Could you try out #215 where I've implemented the Audio model?
