Nothing appears on screen after " raop_rtp_mirror starting mirroring " (Linux Mint 21.1, ipad air gen 3, ipad OS 16.1.1)

[abhishek-anand93]

After setting up the uxplay and installing all the required gstreamer plugins, I tried to connect the iPad to my laptop. The firewall is disabled. The uxplay@hostname shows in the screen mirroring option of the iPad. When I connect it, the terminal stops at

raop_rtp_mirror starting mirroring

and a new window pops up which shows nothing. After trying several times, I came across a suggestion to try running

GST_DEBUG=3 uxplay

and a long list of warnings and errors showed up.

And the errors keep repeating after this. I do not understand how to fix it as I tried to find similar problems but could not.

Thanks in advance.

1. Read the "Troubleshooting" section of UxPlay README

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.)
