Mirroring negotiates and 'initializes' but client never opens data connection (iOS 27, combinedGetInfoWithControlSetup)#535

Summary

Mirroring session connects and negotiates successfully (control connection stays open, /feedback heartbeats keep flowing, server logs "Mirroring initialized successfully" / opens the data port and confirms Accepted IPv6 client on socket...), but the client never opens the actual video/audio data connection. No mirroring window ever appears, since no frame data ever arrives.

Reproduced consistently across four different configurations:

  1. -p (fixed legacy ports 7000/7001/7100 TCP, 6000/6001/7011 UDP)
  2. -p -avdec (forced software h264 decode, ruling out a GPU/VAAPI sink issue)
  3. Default (no -p, random ports)
  4. Default, second clean run after restarting avahi to rule out stale mDNS state

In every case: the control RTSP connection (whatever port it's on) shows ESTABLISHED and stays alive with periodic /feedback POSTs, a data port is opened and logged as ready, but ss -tnp never shows a second ESTABLISHED connection to that data port — the client simply never dials it.

Environment

  • UxPlay 1.73.6 (latest release, built from AUR)
  • Linux (Arch-based), Hyprland (wlroots/Wayland compositor)
  • -vs waylandsink and also tried default autovideosink
  • Client: iPhone16,2, iOS/iPhone OS 27.0 (osBuildVersion in the 24A53xx range), AirPlay client sourceVersion 980.67.2

Relevant detail

The client's SETUP request plist includes:

<key>combinedGetInfoWithControlSetup</key>
<true/>

This key isn't referenced anywhere in the UxPlay source as far as I can tell from the debug log's request handling — suspect the client is negotiating a different data-connection mode than the traditional separate dataPort/SETUP-per-stream flow, and since the server doesn't acknowledge/handle that request, the client never follows through with the classic dataPort connection UxPlay is waiting on.

Debug log excerpt (-d), redacted

Control connection + first SETUP (audio/timing):

SETUP <rtsp-url> RTSP/1.0
X-Apple-ProtocolVersion: 1
Content-Type: application/x-apple-binary-plist

<dict>

</dict>

fairplay_decrypt ret = 0
Client identified as User-Agent: AirPlay/980.67.2
RTSP/1.0 200 OK

Second SETUP (video stream negotiation) — server responds with a dataPort and considers mirroring initialized:

SETUP <rtsp-url> RTSP/1.0
<dict>
  <key>streams</key>
  <array>
    <dict>
      <key>latencyMs</key><integer>100</integer>
      <key>type</key><integer>110</integer>
      <key>streamConnectionID</key><integer>...</integer>
    </dict>
  </array>
</dict>

type = 110
raop_rtp_mirror starting mirroring
raop_rtp_mirror local data port socket 28 port TCP 7100
Mirroring initialized successfully
RTSP/1.0 200 OK

<dict>
  <key>streams</key>
  <array>
    <dict>
      <key>dataPort</key><integer>7100</integer>
      <key>type</key><integer>110</integer>
    </dict>
  </array>
</dict>

After this point, only /feedback heartbeat POSTs continue on the original control connection every ~3s. ss -tnp at any point after this never shows a connection to port 7100 (or whatever data port was negotiated in other test runs). No video pipeline ever receives a buffer, so waylandsink/autovideosink never creates a window (pipeline stays at PAUSED, never reaches PLAYING).

Question

Is combinedGetInfoWithControlSetup a known negotiation mode from newer iOS AirPlay clients that UxPlay doesn't currently implement? Happy to test any patch/branch or provide further packet captures if useful.

    Did you have UxPlay working with iOS 26.x before you installed the iOS 27 public beta?
    (iOS 27 is not yet released, just the beta)

    combinedGetInfoWithControlSetup is not a known mode....

    Hopefully any incompatibility of iOS27 beta with legacy devices will not be there in the final release.

    please post a less "redacted" version of the -d output.

    (1) use uxplay -m -nh to replace the server hardware ID with a random id, remove server name
    (2) just edit the output to replace any data like ip addresses in rtsp:// ......... with xxxxxxxx, dont remove the line itself

    thanks

    Here is a redacted example of the client (an old iPad running iOS 16.7) plist

    Its difficult to go back to iOS 26 from the iOS 27 public beta, so it's not easy to know if your issue is iOS27 changes or something else.

    Thanks for alerting us to possible issues with the forthcoming iOS 27

    Adding another iOS 27 data point, as requested by @fduncanh in #539.

    On an iPhone 15 Pro (iPhone16,1) running iOS 27.0 beta build 24A5355q, with client AirPlay/980.63.2, UxPlay 1.74 built on Windows 11/MSYS2 UCRT64 does establish the mirror data connection and receives video frames.

    Initially, the connection reached mirror setup but then aborted with:

    raop_rtp_mirror: received type 0x01 packet with no payload
this indicates non-h264 video but Airplay features bit 42 (SupportsScreenMultiCodec) is not set

    Starting UxPlay with -h265 fixed that behavior on this client; the client mirrors in HEVC. My behavior is therefore different from this issue: the client does open the mirror data connection.

    I no longer have a full -d capture of the initial SETUP plist, so I cannot confirm whether this client sent combinedGetInfoWithControlSetup. This test also used AirPlay/980.63.2, whereas the report here uses AirPlay/980.67.2, so this result does not rule out a change in the later beta client.

    @LukeProducts thanks for your valuable input. We still have not got a iOS27beta test setup, and hope that iOS27 doesn't break stuff.

    We now have a test system with iPadOS 27 beta 5, to see if iOS 27 is causing any new issues.

    Its probably time to make -h265 on by default, and choose the video size according to whether h264 or h265 is received.

    (probably?) fixed with updates that address iOS and wlroots issues since this issue was posted.

    @jaslrobinson Please close, or confirm that it's still an issue (2026-09-16) .
