Problem with GstDiscoverer on a PNG file

[David Ing]

When I run the GstDiscoverer on a PNG image file I get GST_DISCOVERER_ERROR.

So basically I can't create a GESUriClipAsset from a PNG file because discovery is failing.

Questions ...

1. Is discovery supposed to fail for image files?
2. What is the best way to create a GESClip which displays a PNG image for a period of time?

No, do you have a png decoder available (pngdec)?

GESClip() will create a GESImageSource internally, so that's the correct way,
just use set_duration() as usual :)

Thanks Mathieu ... The problem was that my pngdec plugin was not being picked up.
