Nota: luego de hacer el git clone, puede requerir: sudo pip install protobuf
buscar pssh en wireshark y hacer "copy as hex string"
luego python /home/gmiraval/PycharmProjects/DrmTools/shaka/media/pssh-box.py --from-hex
Ejemplo:
python /home/gmiraval/PycharmProjects/DrmTools/shaka/media/pssh-box.py --from-hex 0000006e7073736800000000edef8ba979d64acea3c827dcd51d21ed0000004e080112106d5488581e933450137c8c4901bcfb931a15766572696d61747269786361626c65766973696f6e221d723d766d785f7769646576696e655f417274656172484426733d3935302a025344
