How to stream video from camera using QT6 and GStreamer?

[ks.zealot]

Currently I am trying to develop videochat application that stream video from camera over rtmp.

So, I need create QUrl that point to gstreamer pipeline. But custom pipeline support was removed from qt6.

How could I add this backend to qt? Or can I intercept raw data in QMediaRecorder and route them to gstreamer pipeline manually?

Hi @ks-zealot,
I could solve this in QT6 using QVideoSink, however, CPU usage is quite high.
My main issue being that I need to memcpy a custom buffer to QVideoframe.
I am willing to help/exchange on this though.
Could you make progress on your end yet?
