[FFmpeg-user] Piped Process

[Farhad H.Ibragimov]

Hi All ,

I have script like this

INPUT="udp://@234.5.2.21:1234"
OUTPUT1="239.65.83.1:1234"
OUTPUT2="239.65.84.1:1234"
OUTPUT3="239.65.85.1:1234"
ffmpeg -loglevel warning -y -i "$INPUT?fifo_size=5120000&buffer_size=10485760&overrun_nonfatal=1" -vcodec copy -strict experimental -dts_delta_threshold 1000 -acodec aac -ac 2 -isync -af aresample=async=1000 -ab 128k -f mpegts - |

Everything  work  fine exept i cant manage PID from that piped process
 .
Is that possible to convert that piped process to one ?

Thanks in advance
