fix(nix): add GStreamer & PipeWire to build inputs #44
Conversation
|
strange, Ignis doesn't require gst-python, it access GStreamer through GObject introspection using pygobject |
|
Well, this is what I get, and when I add the gst-python bindings, the namespace "Gst" becomes available config file supplied is I can close this PR and add a issue, if this is not the right fix. |
Does recording itsekf work (start/stop)?
I am not nix user, so probably will not fix it |
No, actually the config errors out saying GStreamer not found. The underlying error is Gst namespace is not available.
This was my mistake, gst-python is not needed, but the namespace Gst only becomes available when Gstreamer is present (pkgs.gst_all_1.gstreamer) in the buildInputs. After reading through the packaging section on nixpkgs, I see that there is no attribute in mkDerivation called "runtimeInputs", (it only exists of writeShellApplicaition), the buildInputs attribute is what is used to supply runtime dependencies to the package. I would like to keep this PR open, so that after I fix other issues ( pipewire gst plugin not visible ), I could contribute. |

@linkfrg These dependencies seems to solve the dependency issues for me.
Even after solving this dep issue, the recorder seems to hang for me. The XDG portal opens to share the screen and after accepting that ignis becomes unresponsive. I had to kill the process to stop it. so nothing is being saved. But this may be related to another issue You can test this build by using

I get error when trying to record internal audio or audio from microphone: from ignis.services.recorder import RecorderService

TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'Looks like there is some problem with AudioService... |
|
I'm having a hard time debugging this. I have no experience working with PyGObject. @linkfrg any idea where to start? |
Looks like AudioService doesn't work properly on Nix, probably some issue with Gvc, it doesn't detect any audio devices e.g.: from ignis.services.audio import AudioService
audio = AudioService.get_default()
print(audio.speakers)Returns an empty list: |
|
Okay, I will merge this anyway, the issue with AudioService and Gvc should be fixed separately |
Currently the recorder service is not working (atleast for me), because python bindings for GStreamer are not included in build-inputs. so this commit adds that
