3rd party Airplay streamers do not work

[geekpersonman]

Have successfully compiled and installed RPiPlay on my raspberry pi 3b+ using a fresh install of buster off the raspberry pi website. It works great from my iPhone on iOS 13 and my MacBook Pro using Mojave, but the program fails when I try to stream using Airparrot 2 on my Windows 10 laptop. Here is the output log:
Initialized server socket(s)

*** WARNING *** Please fix your application to use the native API of Avahi!

after that the program exits.

Sorry I didn't see that issue before, Thanks! I was already working on getting Miracast going too, I was just hoping to run as little software on the pi as possible.

Since 3rd party clients likely implement the best documented version of the protocol, it probably isn't too much effort to add it into RPiPlay. I won't do it because I don't need it, but if you are willing to invest some time, I'd be happy to help where I can.

Thank you, I'll look into it. I know Kodi has the old version of Airplay mirroring protocol builtin, so maybe most of that code could be reused? Also on an unrelated note I want to add libcec support so my tv will automatically turn on and change the input when a stream connects and turn off when it disconnects.

If you have a working solution for any of these points, please submit a PR! Adding libcec support should likely be as easy as adding a few lines to the video renderer. flush is called when the stream ends.

What IDE are you using to write this? I am currently working in Xcode but I am struggling to get libcec to register in it properly.

For most of the code I used a simple text editor, but I later switched to CLion (I have a student license), since it provides good support for CMake.

Thank you that’s very useful, I had looked into Clion because I love IntelliJ but I didn’t realize it was free for students.
