Hi hdf5plugin devs,

Thanks for this nice library. We're about to begin a project with a team that would like to use the FLAC audio compression filter via h5py, and we thought this project might be a good place for it.

We can work on preparing this contribution over the next few months, but first we wanted to check if you're open to this filter and see if there are any concerns to be aware of.

Thank you very much,
Laurie

Do we first need to register the FLAC filter with HDF5?

commented

In principle what you need first is to produce an HDF5 filter plugin. That way your filter will be usable everywhere and not just via h5py. Once you have something working, you can request an official filter ID.

Thanks, @vasole. I made the request for a filter ID after I filed this issue and they granted one right away, somewhat surprisingly.

We'll work on preparing the HDF5 plugin and preparing a contribution for this project, too. Thanks for the information.

The HDF Portal has undergone changes recently so the correct link for the above information is now: https://portal.hdfgroup.org/documentation/hdf5-docs/registered_filter_plugins.html.
