You can implement a filter like that.  You cannot use a filter like that with 
playbin.  Your approach is incorrect.

Playbin expects to select a video decoder filter for your Mpeg4 video stream, 
which it will pipe through the ffmpegcolorspace and videoscale filters to a 
selected video sink.  Caps are negotiated along the pipeline during the setup 
and preroll.  Once the caps are negotiated, the first frame is sent along the 
pipeline from source to sink.  The same happens for audio.

If you have written a plugin that acts as a video (or audio) sink and expect 
it to take the place of a decoder, you will wait a very, very long time for 
the setup and preroll phase to complete.  I hope your decoder does not use 
hardware that requires a system restart between runs on failure.
