VLC/shoutcast/icecast2 streaming

[whoisalsocalledraich]

Good evening out there!

to my problem: my goal is to stream an arbitrary web radio stream to a shoutcast server (i. e. also transcoding is needed). I tried some hours to find a working output string and searched the web but it didnt work out. What I tried till now:

Streaming incoming ogg stream to icecast2, generated with the vlc gui (selected streaming context menu entry in the playlist window)

Code: Select all

:sout=#duplicate{dst=std{access=shout,mux=ogg,dst=source:hackme@localhost:8000/live}}

Result: working

Added now mp3 transcoding

Code: Select all

:sout=#transcode{acodec=mp3,ab=128,channels=2}:duplicate{dst=std{access=shout,mux=ogg,dst=source:hackme@localhost:8000/live}}

Result: not working, also when indication as mux=raw or mux=mpeg1

Then found some reasonable hints in a forum (maybe here? lost the link...), that the output module shout requires some parameters and that mp3 streams do not have mountpoints (take root mountpoint...) in icecast2

Code: Select all

:sout=#transcode{ab=24,samplerate=11025}:standard{access=shout{mp3},mux=raw,dst=source:hackme@localhost:8000/}

or

Code: Select all

:sout=#transcode{acodec=mp3,ab=128,channels=2}:std{access=shout{mp3=1,bitrate=128},mux=mpeg1,dst=source:hackme@localhost:8000/}}

Result: both not working, although the latter one gave me finally the correct (?) content type (Content Type: audio/mpeg) in the webadmin interface of icecast2. And it was working for this guy.

Then I switched to shoutcast (running on my mac, OS-X 10.4) because icecast2 seems to encourage ogg streams and was designed for that (but shouldnt it also stream mp3? anyway...) but also this didnt help. But I noticed, that the source is disconnecting because there is no data sent. (shoutcast console window: [source] no data (30s timeout). disconnecting). Then I went back to icecast2 and also there mountpoint is vanishing, even though after a shorter time. This lead me to the assumption that the transconding isnt working. So I tried it both under linux and windows environment and with mp3 input streams but always the same result, which means, I think, that this is not a platform dependent mp3 encoder issue (under linux I compiled the ffmpeg with libmp3lame support because the encoder wasnt found). The vlc messages dont show any useful information or errors.

Could anyone help me with this problem? I would appreciate it very much!

You cannot put mp3 in ogg...
Try to put vorbis instead!

[whoisalsocalledraich]

Hi, what I tried was transcoding ogg to mp3. Is that not considered to work? As you can see in my first output string I putted already transcoding to ogg and indicating mux=ogg which was working. But than changing to mp3 is not working! Is my string generally ok?

Thank you for your help,

raich

[Jean-Baptiste Kempf]

You don't understand me.
Your codec (mp3) does not fit in your muxer (ogg)

[whoisalsocalledraich]

Yeah but I changed also the mux, see here

Code: Select all

:sout=#transcode{acodec=mp3,ab=128,channels=2}:std{access=shout{mp3=1,bitrate=128},mux=mpeg1,dst=source:hackme@localhost:8000/}}

is this mux correct? The stream is unfortunately not working.

Greetz,

raich

[Jean-Baptiste Kempf]

why not do acodec=vorb ?

[whoisalsocalledraich]

Because I need mp3 as outcoming stream (my target devices support only that) :

The situation is that the stream connects properly to shoutcast/icecast but is then kicked because no data is sent. Therefore encoding is not working I guess. But what am I doing wrong? Lacking some encoders (under linux, as I said, I compiled ffmpeg with libmp3lame support with no success)?

To help you, we need messages, to completely understand what your problems is.
To fix this, please be sure before you start the playback to:

1. Open: Tools -> Messages.
2. Set Verbosity to 2
3. Start playback to reproduce your issue
4. Save text in a file or copy into clipboard
5. Then paste the full resulting log here between [​code]and[​/code] (or use Pastebin.com if it's too long)

Also don't forget to name your Operating System and provide the VLC media player version.

Hello! I've got the same problem... VLC 0.9.8 compiled from sources

./configure --prefix=/usr/local/stow/vlc-0.9.8/ --enable-x11 --enable-gtk --enable-sdl --enable-ffmpeg --with-ffmpeg-mp3lame --enable-mad --enable-libdvbpsi --enable-a52 --disable-dca --enable-libmpeg2 --enable-faad --enable-vorbis --enable-ogg --enable-theora --enable-faac --enable-freetype --enable-fribidi --enable-speex --enable-flac --enable-caca --enable-skins --disable-skins2 --enable-alsa --disable-kde --enable-qt --enable-wxwindows --enable-ncurses --enable-release --enable-shout --disable-sdl

Translation to icecast2 is possible only with mux=ogg, another variants (raw, mpeg1) is not work.. ((


Working variant:
/usr/local/bin/vlc -vvv udp://@224.1.1.105:2105 --sout '#transcode{acodec=vorb,ab=128,channels=2}:duplicate{dst=std{access=shout,mux=ogg,dst=source:123456@172.31.0.14:8000/r29}}'

Not working:
/usr/local/bin/vlc -vvv udp://@224.1.1.105:2105 --sout '#transcode{acodec=mp3,ab=128,channels=2}:duplicate{dst=std{access=shout,mux=raw,dst=source:123456@172.31.0.14:8000/r29}}'

Ffmpeg converts to mp3 without problem, VLC saves stream to mp3 file without problem...

Any thoughts are welcome! Thanks!
