Luca,

Look like I'm doing something wrong, I can't made this works

Here command I run:
avconv -i rtp://10.xxx.xxx.xxx:7650 -strict experimental -c:a:i:2300 aac
-b:a 384k -c:v copy -f flv
rtmp://10.xxx.xxx.xxx:1935/live/live_1_8000.stream

here my input Metadata:

Input #0, rtp, from 'rtp://10.xxx.xxx.xxx:7650':
  Duration: N/A, start: 3264.759156, bitrate: 768 kb/s
    Stream #0.0: Video: h264 (Main), yuv420p, 1920x1080 [PAR 1:1 DAR 16:9],
29.17 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    Stream #0.1: Audio: ac3, 48000 Hz, 5.1, fltp, 384 kb/s
    Stream #0.2: Audio: ac3, 48000 Hz, 5.1, fltp, 384 kb/s
Output #0, flv, to 'rtmp://10.xxx.xxx.xxx:1935/live/live_1_8000.stream':
  Metadata:
    encoder         : Lavf54.20.3
    Stream #0.0: Video: libx264, yuv420p, 1920x1080 [PAR 1:1 DAR 16:9],
q=2-31, 1k tbn, 90k tbc
    Stream #0.1: Audio: aac, 48000 Hz, 5.1, fltp, 384 kb/s
Stream mapping:
  Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (ac3 -> aac)
Press ctrl-c to stop encoding


Is some way to read the PID Numbers? or I'm using incorrect syntax?

Thanks again!
Alejandro
