Low-end cameras are may not support higher resolution and framerate due to
bandwidth limitations. You can check you camera capabilities using:

  gst-device-monitor-1.0 Video/Source

or
  
  v4l2-ctl --list-formats-ext -d0

Most likely, if 720p at 30 is supported, it will be provided as jpeg, and you will
have to use jpegdec or similar element.
