    Seems there is a missmatch with the ffmpeg backend, it tries to load libssl.so.1.1 or libssl.so.1 (straced the binary, Qt core itself finds v3 libssl.so just fine) and on a system that is on OpenSSL 3 only it obviously won't find that, leading to the problem that any https urls won't play.
    Easy to test with the Media player example.
    This is on 6.5.3 and unfortunately 6.6.0 too. Linux Mint 21.2

          @oniongarlic said in QtMultimedia ffmpeg backend and Openssl library version mixup:

          how else ?

          By compiling, or on Linux by using distribution packages, ...

            @jsulm in that case I would probably tell about my build environment, etc.

            Anyway, still won't work with ffmpeg backend. Fortunately the gstreamer backend is still there and it works.

              @oniongarlic yes, I can confirm that ffmpeg backend cant playback rtsp streams. Not sure if its due to ssl library not found error

                My problem is with HLS streams, I get the first frame and then an error (ffplay works fine) (Windows, Mac) Linux won't even get that far with this ssl issue.
