Backport change that unbreaks gstreamer-editing-services. A test still doesn't pass, but Debian feels confident enough to just skip so why not follow.

Subject: [PATCH] ges: Move OTIO formatter to a separate Python plugin
|
|
|
|
The GES OpenTimelineIO formatter was previously embedded directly in
|
|
libges using GLib resources, this was all a bit complex for not much
|
|
benefit, moreover it started to crash recently.
|
|
|
|
Move the formatter to a standalone Python plugin that will be loaded
|
|
through the standard GStreamer Python plugin infrastructure making
|
|
it all more simple.
|
|
|
|
The formatter is now located in subprojects/gst-python/plugins/ges/
|
|
and will only be loaded when the Python plugin is available and
|
|
opentimelineio is installed.
|
|
|
|
