[FFmpeg-user] combining "volumedetect" and "ebur128" audio filters

I'd like to use the "volumedetect" and "ebur128" filters on the same audio stream, but have not figured out a syntax to support this.  Each one works fine, but the first is required to measure the signal peak level and second for the EBU/ITU loudness.  Only the measurement results are needed.  The command line I'm using is:
ffmpeg -i http://stream_URL -filter ebur128 -f null -y null
ffmpeg -i http://stream_URL -filter volumedetect -f null -y null

Any direction would be appreciated.
