Gstreamer warnings

[ajnart]

Please describe the issue in as much detail as possible, including any errors and traces

While attempting to use howdy, it gives me these warnings:

[ WARN:0] global /build/opencv/src/opencv-4.2.0/modules/videoio/src/cap_gstreamer.cpp (1758) handleMessage OpenCV | GStreamer warning: Embedded video playback halted; module source reported: Could not read from resource.
[ WARN:0] global /build/opencv/src/opencv-4.2.0/modules/videoio/src/cap_gstreamer.cpp (888) open OpenCV | GStreamer warning: unable to start pipeline
[ WARN:0] global /build/opencv/src/opencv-4.2.0/modules/videoio/src/cap_gstreamer.cpp (480) isPipelinePlaying OpenCV | GStreamer warning: GStreamer: pipeline have not been created

Linux distribution (if applicable): Arch Linux 86_64

Howdy version: 2.5.1-2

Thank you! After a recent update on Debian Testing, I started experiencing this same issue. Confirming your patch fixed it for me.

Can confirm the same, thanks!

This has to be changed again for 2.6.0 see https://github.com/boltgolt/howdy/blob/master/src/recorders/video_capture.py#L116

Fix got rid of the WARNs, but INFO logs can still create issues for GUI applications, eg. 1Password. Tried setting OPENCV_LOG_LEVEL=ERROR in /etc/environment but still get info logs that causes an infinite loop of retries.'

Seeing this (repeated until the app is killed) in the logs:

Jun 10 13:36:13 fedora polkit-agent-helper-1[3851]: [HOWDY] Attempting facial authentication for user anders

@baelter were you able to fix this? I would like to enable face recognition for polkit on fedora 34 with gnome and this issue is a blocker.

[baelter]

@petre2dor Nope 😔

I am seeing the same error on fedora 40 today. Howdy is working, but it takes a lot of time for it to start.
