Hi,

I'm trying to learn more about gstreamer, and have found lots of examples like:

gst-launch-0.10 v4l2src ! ffmpegcolorspace ! pngenc ! filesink location=foo.png

When I try and run tnis though I get a warning:

WARNING: erroneous pipeline: no element "pngenc"

Any suggestions? I've hunted around for a package etc, but can't find one

thanks
