@jadahl Thanks for this, I've created a similar snippet for screen-shots based on this in https://gitlab.gnome.org/snippets/814

Could this be updated for more recent versions of python3-gi? Or at least inform which version-range it would work with?

Could this be updated for more recent versions of python3-gi?

Hmm,

>>> import gi
>>> gi.version_info
(3, 38, 0)
>>> gi.repository
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'gi' has no attribute 'repository'
>>> gi.Repository
<class 'gi.Repository'>

but the script still works.

FWIW, I removed the deprecated GObject.threads_init() so that warning should no longer occur.

@jadahl Hello. Thanks for this code. How can I record in MP4 with sound? The examples I've used before with ximagesrc don't work ...

@amikha1lov you need to set up your own gstreamer pipeline that combines some audio source with the pipewire stream; it's more of a gstreamer question.

Is it possible to do an example of this with gst-launch-1.0 pipewiresrc ! videoconvert ! autovideosink and dbus-send?

I am talking about the commands and in bath, I understand little of python. So if it is possible to make an example in bath it would help me a lot

I tried it and it seems to work for me, but I don't want to use python for what I'm developing

For it to work properly, you need to pass a file descriptor from the D-Bus call to the gstreamer pipeline (see the fd=.. part of the gstpipewiresrc element); I'm not sure you can do that with bash and dbus-send.

Well after being able to recreate this for my application, I couldn't find a way to save the output in a .mp4 video.

try things like pipeline = Gst.parse_launch('pipewiresrc fd=%d path=%u ! videoconvert ! x264enc ! mp4mux ! filesink location=hola.mp4 '%(fd, node_id)), but this created a blank file.

Then I tried this, gst-launch-1.0 pipewiresrc path=75 ! videoconvert ! filesink location=fileRare it seems to save something but I really don't know what to do with it.

I don't really know where to start, but all I want to do is capture the output and save or stream it. It would help me a lot if you can give me a hint for this

@andrusdiazaleman Perhaps look at how GNOME Shell does it: https://gitlab.gnome.org/GNOME/gnome-shell/-/blob/main/js/dbusServices/screencast/screencastService.js
