Hi,

I have been trying to use your code to convert .h5 files to rosbags, but i keep having the same error while trying to execute a conversion, this ks the error:

Any ideas how i can resolve this ?

Hi @aelmoudni , looking at the error message it seems that the blosc filter used for data (de-)compression was not found in your system. Which version of Ubuntu and libhdf5 are you using? Did you install the blosc filter plugin and copy the generated libH5Zblosc.so library file in your system's hdf5 plugins directory? In Ubuntu 20.04, the plugins path is usually /usr/lib/x86_64-linux-gnu/hdf5/plugins. If this path does not exist for you, can you run dpkg -L libhdf5-dev on your terminal and post your output here?
