[FFmpeg-user] HLS-Stream via ffmpeg/Mediaserver to TV

[Thomas Schmiedl]

I tried with this command on a linux pc:

ffmpeg-3.0.1-installation/bin/ffmpeg -i 
http://62.113.210.250/medienasa-live/_definst_/mp4:tvhalle_high/playlist.m3u8 
-acodec copy -vcodec copy -f mpeg -listen 1 http://192.168.178.27:8899

output:

Press [q] to stop, [?] for help

The stream plays on the TV, but without audio. When I stop the stream on 
the TV, ffmpeg exits with:

[http @ 0xa84e780] Stream ends prematurely at 472320, should be 
17066643.3kbits/s speed= 1.6x

What I need to add in the command for audio output and that ffmpeg does 
not exit. DLNA-server is mediatomb.
