[Bug]: getting external display video display filter frame events

[LaloRiojas]

Context

I am trying to make a phone/qrreader on linux wayland with qtwidgets and i need to access the display MSFilter of a video call so that i can set the ms_notify_callback to a static function that will let me render the yuv420p video to a QVideoFrame widget. Is there any API in a video call that allows me to get to the mediastreamer2 video filters.

notes
yes i know that qtquck is better for liblinphone because of the msqol display filter for video but the project is already big and unable to be easily modified and the target has some opengl issues that are not really worth solving for this.

i have already tested the external display -> QvideoWidget video rendering with a basic QR code reader feature in my application. works flawlessly and after some testing i saw that the video rendering in this way was not a bottleneck at all compared to the MJPEG -> YUV conversion with turboJPEG and QRCODE reading with ZXrossing.

This project MUST work on wayland (and perferably not through XWayland) because this is for a KIOSK running on ubuntu frame.
