example concatenate.c hangs

Submitted by ham..@..gmx.de

Link to original bug (#797341)

Description

i checked out the git repo of gst-editing-service (tag 1.14.4 - hash
712ad28d).

i compiled and ran gst-editing-services/examples/c/concatenate.c

./concatenate file:///tmp/result.mp4 file:///tmp/1.mp4 file:///tmp/2.mp4

It just hangs and never ends without any errors. I tried several things without success. I waited several minutes and had to kill the process with CTRL+c. The file /tmp/result.mp4 is created but has size of 0 bytes.

The input files are from smartphone 1920x1080. i copied one file twice.

Version: 1.14.x
