no handler for "/pair-pin-start"

[warren-bank]

Hi. First of all.. this is amazing work!

My test device is:

• iPhone 8 running iOS 15.0.2

I compiled and tested a few of the demo servers..

• vlcj-player
  • started perfectly..
  • screen mirroring failed
• h264-dump
  • started perfectly..
  • size of dump.h264 is 0
  • text log file contains some interesting insight..

summary:

# request 1
GET /info RTSP/1.0
X-Apple-ProtocolVersion: 1
Content-Type: application/x-apple-binary-plist
CSeq: 0
DACP-ID: xxxxxxxxxx
Active-Remote: xxxxxxxxxx
User-Agent: AirPlay/566.25.21
content-length: 70, 70B

# response 1
RTSP/1.0 200 OK
CSeq: 0
content-length: 689, 689B

# request 2
POST /pair-pin-start RTSP/1.0
CSeq: 1
DACP-ID: xxxxxxxxxx
Active-Remote: xxxxxxxxxx
User-Agent: AirPlay/566.25.21
content-length: 0, 0B

# response 2: none

inspection of code:

• PairingHandler
  • presumably, this class would be responsible for handling the "/pair-pin-start" request endpoint
  • but, it doesn't appear to be implemented

final thoughts:

• I'm not an Apple user.. so I have no idea if there's some setting on the phone that I could change to cause AirPlayer to pair to the receiver using different endpoints that are implemented (ie: "/pair-setup" and "/pair-verify")
• any insight would be appreciated
• and again.. great work!

this is my first attempt to implement the 3-step pairing handshake..

• it seems to work as I had intended (based on inspection of code from an open-source AirPlay2 client app)
• but my testing iPhone doesn't like the computed M2 response from the server at step 2
  • so either I made a silly mistake somewhere, or the client code it's based on isn't accurate

@warren-bank

There is interest in adding pair-pin-start support to UxPlay AirPlay server http://github.com/FDH2/UxPlay

could you share details of which open-source AirPlay2 client app you are using as source?
(please post as an issue at the UxPlay github project )

Thanks!

EDIT: probably you refer to https://github.com/warren-bank/Java-AirPlay2-Receiver

EDIT2: OK it is https://github.com/openairplay/AirPlayAuth (I think)
