LZF Support in HDF 1.12.x

HDF5 Library
1

Is the LZF compression supported by 1.12.x? I had a look at the https://support.hdfgroup.org/services/filters.html#lzf page but it isn’t particularly clear? We are trying to read a dataset that was compressed with LZF but get HDF5 errors when we try to read data from the file.

Thank You

We do build a plugin for LZF. See our hdf5_plugins repo.
They are in our standard hdf5 binaries plus the plugins binary should be available for download.
