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:

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

I try to receive this HLS-stream:
http://62.113.210.250/medienasa-live/_definst_/mp4:tvhalle_high/playlist.m3u8
on my router (Fritzbox 7312; MIPS-based) via a mediaserver (e.g.
Mediatomb) and transfer the stream to my DLNA-TV (Panasonic).
The TV doesn't play the .m3u8 directly ("file not readable"). My idea is
to process the .m3u8 in ffmpeg (without transcoding), which sends the
stream to a network socket, the mediaserver reads from this socket and
transfers the stream to my TV.
Isn't mediatomb itself capable of sourcing from HLS URLs? I don't
remember. (I may be confusing it with Universal Media Server.)
What sort of socket are you thinking of? Is the mediaserver listening
on a socket of its own? Is it connecting to another server's socket?
What protocol does it expect? (Pure TCP/UDP, or HTTP? RTMP, RTSP?) What
container types will it accept?
Anyway: ffmpeg can host its own listening socket, e.g.:
$ ffmpeg -f lavfi -i testsrc2 -c:v libx264 -f matroska -listen 1
tcp://localhost:1234
$ ffmpeg -f lavfi -i testsrc2 -c:v libx264 -f matroska -listen 1
http://localhost:8899
ffmpeg can send to another host's socket, e.g.:
$ ffmpeg -f lavfi -i testsrc2 -c:v libx264 -f mpegts udp://otherhost:2222
Could someone help me to realize this? I'm not an expert in this issue.
You need to be more precise in terms of what your environment needs.
One of those three examples could work, but what do we know. ffmpeg
can't host DLNA by itself though AFAIK, but that's what you have
mediatomb for.
