 <p>This triggers an unending stream of error messages, and means that the audio decryption key (also used in video decryption) was not correctly extracted from data sent by the client. This should not happen for iOS 9.3 or later clients. However, if a client uses the same older version of the protocol that is used by the Windows-based AirPlay client emulator <em>AirMyPC</em>, the protocol can be switched to the older version by the setting <code>OLD_PROTOCOL_CLIENT_USER_AGENT_LIST</code> in lib/global.h. UxPlay reports the client’s “User Agent” string when it connects. If some other client also fails to decrypt all audio and video, try adding its “User Agent” string in place of “xxx” in the entry “AirMyPC/2.0;xxx” in global.h and rebuild uxplay.</p>
 <p>Note that Uxplay declares itself to be an AppleTV3,2 with a sourceVersion 220.68; this can also be changed in global.h. It had been thought that it was necessary for UxPlay to claim to be an older 32 bit AppleTV model that cannot run modern 64bit tvOS, in order for the client to use a “legacy” protocol for pairing with the server (see the <em>“Notes on AirPlay protocol versions”</em> at the end of this README). However, UxPlay still works if it declares itself as an AppleTV6,2 with sourceVersion 380.20.1 (an AppleTV 4K 1st gen, introduced 2017, running tvOS 12.2.1), so it is unclear what setting prompts the client to use the “legacy” protocol needed by UxPlay.</p>

 <p>1.50 2022-04-22 Added -fs fullscreen option (for Wayland or VAAPI plugins only), Changed -rpi to be for framebuffer (“lite”) RPi systems and added -rpigl (OpenGL) and -rpiwl (Wayland) options for RPi Desktop systems. Also modified timestamps from “DTS” to “PTS” for latency improvement, plus internal cleanups.</p>
 <p>1.49 2022-03-28 Addded options for dumping video and/or audio to file, for debugging, etc. h264 PPS/SPS NALU’s are shown with -d. Fixed video-not-working for M1 Mac clients.</p>
