            Bug ID: 771378
           Summary: smart rendering mode is broken
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-editing-services
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: slomo at coaxion.net
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

It's currently broken on multiple layers:

1) there is no option in ges-launch, that's trivial though ;)
2) set_render_settings() will create the pads on encodebin and allows to set
the output filename, set_mode() allows to set the avoid-reencoding property on
encodebin. The property must be set before the pads are created, but the output
filename must be set before set_mode() is called with the SMART_RENDER mode. I
propose to make the output filename only required once the pipeline goes to
READY, and not check for that before.
3) in the lower layers things go wrong when working around all the above, I
didn't investigate further. The pipeline got stuck.
