To my understanding your pipeline creates a video-stream but no .mp4 file. If you want to store the video you need a muxer element to pack the video into a container. There is qtmux for mp4-containers or matroskamux for mkv-containers, but unfortunately I have only been able to use matroskamux in a pipeline.
