discoverer hangs when processing media file containing mebx on MacOS

Describe your issue

gst-discoverer-1.0 sometimes hangs on shutting down gracefully when processing video containing mebx streams inside

Expected Behavior

gst-discoverer-1.0 to shutdown gracefully without hanging

Observed Behavior

Running it like that:

GST_DEBUG=discoverer:5 gst-discoverer-1.0 ~/Pictures/IMG_5883.MOV

In most cases it hangs and I see the following on stdout/err: discoverer_hang_stdout.txt Sometimes it does not and then this is what I get: discoverer_no_hang_stdout.txt

Setup

• Operating System: MacOS M3, 14.4.1
• Device: Computer
• GStreamer Version: 1.24.2
• Command line: gst-discoverer-1.0 ~/Pictures/IMG_5883.MOV

How reproducible is the bug?

Sometimes. Looks like some race condition (?)
