omx-java currently requires to use an x64-JVM on macOS as no native libraries (libjhdf, libjhdf5) are provided for Apple Silicon (ARM64).
Searching the web for an alternative source where to download libjhdf5 for macOS-aarm64 yielded no useable results, so I think it would be very helpful if you could provide the corresponding libraries to ensure omx-files can be read and written on future macOS versions.
