For information: I found the '--rtmp-liveradio-opts --live' option doesn't always prevent invalid timestamps, although it helps prevent it. More details here: http://ffmpeg.org/pipermail/ffmpeg-user/2011-June/001323.html If you get the error 'invalid, non monotonically increasing dts to muxer in stream' I found a workaround.
