It ultimately ended up being the parameters I was passing to the x264enc element. I would take a look at those with gst-inspect and see if you can tune the output.

My pipeline works to read a YUV file at the sender, encodes it in H.264, and sends it to receiver using RTP in encoding time. At the receiver, it receives the stream and stores it in YUV format again for posterior process.
