it doesnt work either if I modify like this:
ffmpeg -f alsa -i hw:0,0 -f lavfi -i nullsrc -filter_complex
"[0]showwaves=split_channels=1:s=1280x720:mode=line:colors=Red|Blue"

Hi Guys,
I'd like to send the audio with waveform overlay for both channels, I can
save it to file:
ffmpeg -f alsa -i hw:0,0 -filter_complex
"showwaves=split_channels=1:s=1280x720:mode=line:colors=Red|Blue" out.mp4
However with ffserver it fails:
ffmpeg -f alsa -i hw:0,0 -filter_complex
"showwave
