GStreamer source element for AirPlay video streams

gst-airplay's Issues

No Element "airplaysrc" when using OBS from Flatpak

Hello,

I'm trying to use this in OBS with the given line:
airplaysrc ! queue ! h264parse ! avdec_h264 max-threads=1 ! videoconvert ! videoscale ! video.

Which OBS gives an error of:
error: [obs-gstreamer] ipad: Cannot start pipeline: no element "airplaysrc"

I do know that the pluging is correctly installed as I can run
gst-launch-1.0 airplaysrc ! queue ! h264parse ! avdec_h264 max-threads=1 ! autovideosink
and get a window with the correct screen mirroring.

I'm thinking this might be because I'm using the Flatpak version of OBS on Arch. But I'm not confident in that being the reason.

Cannot find run-time dependency airplay during `meson build`

Hi! I'm running Pop OS 21.04 and am following the build instructions. I got as far as the meson build step without issue, but then I get this error:

Is there something I'm doing wrong? Thanks!

Unable to connect to "gstairplay"

I managed to finish building.

Running gst-inspect-1.0 shows some plugins but doesn't show libgstairplay.so.
I updated the $GST_PLUGIN_PATH to point to the libgstairplay.so object.

I also tried providing the path in gst-launch-1.0, but mirroring still doesn't work. More specifically, I can see gstairplay as a destination, but my ipad simply says ' Unable to connect to "gstairplay" '.

Any pointers would be appreciated!

Use RPiPlay as a meson subproject

meson knows how to use subproject through wrap files, and has a compatibility module that allows building cmake subprojects.

This would make it easier to build this project, pass the right options, etc.

See https://mesonbuild.com/CMake-module.html

How I can contact you by email?

@knuesel: How I can contact you by email?

Can I have your email address?

You can remove this ticket after sending the reply ^^

Thanks in advance.

Export use as a property

It would be super useful for building applications to know whether there's a client connected or not, so that the application could show a "rest" screen and only switch when a connection has been made.
