AMF is a well known format. It's called Adobe Media Format and is the
packetization used to produce FLV. All this looks like some different
way of doing RTMP, any reason not to use RTMP instead ?

You would have to parse the bitstream and this is format dependant.
Though, if it's not a delta, it's a keyframe. AMF packetization does
not require this information though.
