Audio stream from camera

[attilhacks]

Question

Hello All,

I have this camera stream:

Metadata:
   title           : Media Presentation
 Duration: N/A, start: 0.000000, bitrate: N/A
 Stream #0:0: Video: hevc (Main), yuvj420p(pc), 640x360 [SAR 1:1 DAR 16:9], 8 fps, 25 tbr, 90k tbn
 Stream #0:1: Audio: pcm_mulaw, 8000 Hz, mono, s16, 64 kb/s

I would like to restream it in order to publish it with icecast: I'm trying to follow this example but it's not very clear to me..

ffmpeg -re -i ... -map 0:a:0 -c copy -f rtsp rtsp://localhost:8554/mypath
