Packet Anatomy
Protobuf
The messages exchanged between the Android app and the camera use
Protocol Buffers,
which is an open standard by Google. To decode the messages, you need the
specific language description files (*.proto files) which can be extracted
from the compiled binary file libOne.so from the official Insta360 app by
decompiling it.
