Subject:  [FFmpeg-user] Real Time Transcoding

Hi ,

I am mixing 2 audio streams and transcoding to mp3 stream . I am able to
get the output  in real time initially but with time the output is being
delayed and is not in real time .

My command is
ffmpeg -probesize 2048 -analyzeduration 1 -i http://xx.yy.zz/stream1.mp3 -i
rtmp;//xx.yy.zz/stream2.flv amix -filter_complex
amix=inputs=2:duration=first  -ca libmp3lame -ab 128k  -ar 44100 -f mp3 - >
| named pipe .

Is there any other input parameter that should be added to get the real
time output always ?
