[FFmpeg-user] ffmpeg hang in background

[DopeLabs]

here is an example of one of the commands i have running without any issues...

ffmpeg -d -i http://127.0.0.1:5000 -r 60 -i viz.mp4 -loop 1 -i mask.png -filter_complex lowpass=600,showwaves=s=1280x720:mode=cline:r=60:colors=random|random[viz];[1:v]scale=1280x720,setsar=1/1[sun];[viz][sun]blend=all_mode=heat:shortest=1[bg];[bg][2:v]blend=all_mode=overlay:shortest=1:repeatlast=0:enable=lt(mod(t\,300)\,5),drawtext=fontfile=d3.ttf:fontsize=38:fontcolor=gray:text=DSFM.TV:x=5:y=(h-text_h)-5,drawtext=fontfile=helvbold.ttf:fix_bounds=true:fontsize=28:textfile=nowplaying.txt:fontcolor=gray:reload=1:y=(h-text_h)-5:x=(w-text_w)/2:enable=lt(mod(t\,60)\,15),drawtext=fontfile=helvbold.ttf:fontsize=24:fontcolor=gray:textfile=tuneid.txt:reload=1:y=5:x=(w-text_w)/2,drawtext=fontfile=helvbold.ttf:fontsize=24:fontcolor=gray:textfile=date.txt:reload=1:y=5:x=(w-text_w)-5:enable=lt(mod(t\,60)\,15),drawtext=fontfile=d3.ttf:fontsize=38:fontcolor=gray:textfile=count.txt:reload=1:x=(w-text_w)-5:y=(h-text_h)+20,hue=H=2*sin(400*PI/600*t) -s 1280x720 -c:a libfdk_aac -b:a 256k -c:v libx264 -preset ultrafast -profile:v high -level 4.2 -g 120 -bf 4 -x264opts keyint=120:min-keyint=120:8x8dct=1 -pix_fmt yuv420p -r 60 -f flv rtmp://127.0.0.1/live/viz

in short it grabs my net radio stream and outputs visualizations and adds text for the current playing mix, when the air date was, and the current number of people watching... i publish the stream at dsfm.tv

nothing that changes pts mid stream though.. that sounds like it wouldnt be good though...
