Rendering Raw video with gstreamer

So using y4menc I would capture the video frames in a buffer, push the 
buffer into a pipeline using appsrc, then link appsrc to y4menc, and 
then write the information to a file.

Essentially - buffer->appsrc->y4menc->filesink

Then to play the file - filesrc->videoparse->autovideosink

Does this seem correct or am I doing this incorrectly?

One of my development steps right now is to write the buffers into a file, and try to play that file with gstreamer.  I am using the following pipeline to try and play the file:
