[Gambas-user] MediaPlayer bug with AboutToFinish and URL?

[Piper984]

OK, thanks for continuing to look into it!

In case it helps: Below is a Python script + Gstreamer lib where setting the
URL property behaves as expected.  It just toggles between playing two video
clips, setting the URL property when the 'about-to-finish' event fires. Not
sure if this will be of any use, but it might?  I ran this script w/ Ubuntu
16.04 and GStreamer 1.8.2, which is a different system than the one I
originally asked about.  I have confirmed that running Gambas 3.9.0 on the
same system that the Python script below runs doesn't behave as expected.

Thanks again!
