<p><strong>-reset n</strong> sets a limit of n consective timeout failures of the client to respond to ntp requests from the server (these are sent every 3 seconds to check if the client is still present). After n failures, the client will be presumed to be offline, and the connection will be reset to allow a new connection. The default value of n is 10; the value n = 0 means “no limit” on timeouts.</p>
<p><strong>-nc</strong> maintains previous UxPlay &lt; 1.45 behavior that does <strong>not close</strong> the video window when the the client sends the “Stop Mirroring” signal. <em>This option is currently used by default in macOS, as the window created in macOS by GStreamer does not terminate correctly (it causes a segfault) if it is still open when the GStreamer pipeline is closed.</em></p>
<p><strong>-t <em>timeout</em></strong> will cause the server to relaunch (without stopping uxplay) if no connections have been present during the previous <em>timeout</em> seconds. You may wish to use this if the Server is not visible to new Clients that were inactive when the Server was launched, and an idle Bonjour registration eventually becomes unavailable for new connections (this is a workaround for what may be due to a problem with your DNS-SD or Avahi setup). <em>This option is currently disabled in macOS, for the same reason that requires the -nc option.</em></p>
<p><strong>-vdmp</strong> Dumps h264 video to file videodump.h264. -vdmp n dumps not more than n NAL units to videodump.x.h264; x= 1,2,… increases each time a SPS/PPS NAL unit arrives. To change the name <em>videodump</em>, use -vdmp [n] <em>filename</em>.</p>
<p><strong>-admp</strong> Dumps audio to file audiodump.x.aac (AAC-ELD format audio), audiodump.x.alac (ALAC format audio) or audiodump.x.aud (other-format audio), where x = 1,2,3… increases each time the audio format changes. -admp <em>n</em> restricts the number of packets dumped to a file to <em>n</em> or less. To change the name <em>audiodump</em>, use -admp [n] <em>filename</em>.</p>
<p><strong>-d</strong> Enable debug output. Note: this does not show GStreamer error or debug messages. To see GStreamer error error and warning messages, set the environment variable GST_DEBUG with “export GST_DEBUG=2” before running uxplay. To see GStreamer debug messages, set GST_DEBUG=4; increase this to see even more of the GStreamer inner workings.</p>

<h3 id="problems-after-the-client-server-connection-has-been-made">3. Problems <em>after</em> the client-server connection has been made:</h3>
<p>If you do <em>not</em> see the message <code>raop_rtp_mirror starting mirroring</code>, something went wrong before the client-server negotiations were finished. For such problems, use “uxplay -d” (debug log option) to see what is happening: it will show how far the connection process gets before the failure occurs. You can compare your debug output to that from a successful start of UxPlay in the <a href="https://github.com/FDH2/UxPlay/wiki">UxPlay Wiki</a>.</p>
<p><strong>If UxPlay reports that mirroring started, but you get no video or audio, the problem is probably from a GStreamer plugin that doesn’t work on your system</strong> (by default, GStreamer uses the “autovideosink” and “autoaudiosink” algorithms to guess what are the “best” plugins to use on your system).</p>
<p><strong>M1 (Apple Silicon) Macs stream video with h264 profile High at level 4.2, as opposed to High at level 4.1 (streamed by Intel Macs). Currently, this is not being correctly recognized by GStreamer, and a video window fails to open when the client is a M1 Mac. Audio streaming is unaffected. </strong> See <a href="https://github.com/FDH2/UxPlay/issues/73">here</a> for efforts to fix this.</p>
<p><strong>Raspberry Pi</strong> devices (-rpi option) only work with hardware GPU decoding if the Video4Linux2 plugin in GStreamer v1.20.x or earlier has been patched (see the UxPlay <a href="https://github.com/FDH2/UxPlay/wiki/Gstreamer-Video4Linux2-plugin-patches">Wiki</a> for patches). This may be fixed in the future when GStreamer-1.22 is released, or by backport patches in distributions such as Raspberry Pi OS (Bullseye).</p>
<p>Sometimes “autovideosink” may select the OpenGL renderer “glimagesink” which may not work correctly on your system. Try the options “-vs ximagesink” or “-vs xvimagesink” to see if using one of these fixes the problem.</p>
<p>Other reported problems are connected to the GStreamer VAAPI plugin (for hardware-accelerated Intel graphics, but not NVIDIA graphics). Use the option “-avdec” to force software h264 video decoding: this should prevent autovideosink from selecting the vaapisink videosink. Alternatively, find out if the gstreamer1.0-vaapi plugin is installed, and if so, uninstall it. (If this does not fix the problem, you can reinstall it.)</p>
<p>There are some reports of other GStreamer problems with hardware-accelerated Intel HD graphics. One user (on Debian) solved this with “sudo apt install intel-media-va-driver-non-free”. This is a driver for 8’th (or later) generation "*-lake" Intel chips, that seems to be related to VAAPI accelerated graphics.</p>
@@ -130,6 +135,7 @@
<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>
