Why does it not work? You might've made a typo in the above pipeline, it
should be

> filesrc location=plop.png ! pngdec ! imagefreeze ! videoconvert ! video/x-raw,format=RGB ! appsink
(note the comma between raw and format)

If that still does not work, please provide some more information about
what happens. Like terminal output, GStreamer debug logs, etc.
