Playback tutorial 7 not working as expected with GStreamer 1.20.3 on macOS 10.15.7

[Petros Kataras]

Hey all,

I have a GStreamer playbin pipeline configured with an appsink as the video-sink property that has been working consistently since much earlier versions of GStreamer and up to 1.18 but seems to have stopped working ( no error output when using GST_DEBUG but the app crashes inside one of GStreamer’s threads ) with the current 1.20.3 version.

The overall pipeline structure is very similar to the playback tutorial 7 but with video instead of audio and thus I decided to test with the specific example and although I m not getting a crash here I also don’t get no window or audio coming up - the app just exits without any errors when using GST_DEBUG.

Before going down the road of manually compiling from sources in order to try to get more info on the exact location of the crash on my app I was wondering if anyone from the team can confirm that the specific tutorial is not behaving as expected so that we can maybe identify where this regression comes from.

As stated I m currently testing this on macOS 10.15.7 with version 1.20.3 and can confirm that all other examples/tutorials that I tried work as expected.

Any ideas would be more than welcome.

Thanks a lot,
Petros
