[FFmpeg-user] FFplay - Audio bars on video

[DopeLabs]

It will work if you use ffmpeg and pipe to ffplay... here is one example

ffmpeg -loglevel 0 -i rtmp://video/live/stream -filter_complex "[0:a]pan=1c|c0=c0,showvolume=r=60:b=0:t=0:v=0:w=720:h=80:f=0.5:o=1[left];[0:a]pan=1c|c0=c1,showvolume=r=60:b=0:t=0:v=0:w=720:h=80:f=0.5:o=1[right];[left][0:v]hstack[tmp1];[tmp1][right]hstack" -c:v h264 -preset ultrafast -c:a copy -f flv - | ffplay -f flv -
