Dear Eduardo, thanks for the support. I was planning to use liquidsoap with wowza to offer radio broadcasters an HLS audio stream for iOS and Android devices.
Now my problem is to ADD metadata to the audio source I get from the sound card (line in channel) and embed them together in an RTMP stream for Wowza. If I use Icecast/Shoutcast, I need to put an additional Icecast/Shoutcast server between my "encoder" and Wowza (i.e. encoder -> icecast server -> wowza -> mobile client), and I do not love it very much. In addition, I want audio and metadata to be embedded in the encoder (as in shoutcast v2), not in the server (using an HTTP GET request as it is done in shoutcast v1). So, I have a PC playing the playlist (with mbstudio http://www.mbradio.it/it/mb-studio, for example), then audio and metadata are splitted: - the audio goes analog, it is processed with "commercial grade" multiband filters, levelers, companders and so on; - the metadata (title and artist) is copied on a file on a shared folder Thus, in another PC, I need to get the audio back from the sound card (line in), encode it, and match it with the metadata I read from a file (when it changes), embed them in RTMP and send all along to the Wowza server. I tried with ffmpeg, then with gstreamer, but I could not find a way to "control" the metadata tags insertion at any point in the live stream. I think liquidsoap can do that via OSC or the telnet server, but I have no clue on how to do that and create a gstreamer pipeline that is working with rtmp and flvmux. Liquidsoap is a great platform, but tough, If anyone can help it would be very much appreciated. - Antonio On Fri, Oct 21, 2016 at 8:24 PM, Eduardo Martinez <erm13marti...@gmail.com> wrote: > Antonio, > > Wowza can already restream Icecast/Shoutcast streams natively, including > metadata. > What is the specific need for RTMP/RTSP transport in? > > On Fri, Oct 21, 2016 at 10:53 AM, Antonio Servetti < > antonio.serve...@polito.it> wrote: > >> Dear users, >> >> I know that liquidsoap supports streaming to icecast and shoutcast, >> but I really need something that can stream audio plus metadata to Wowza >> that is able to receive RTMP or RTSP. >> >> Is liquidsoap able to stream one of them? maybe using gstreamer? >> Can metadata be embedded with the audio at the sender? >> >> If it is not jet possible, can you provide some advice on adding this >> feature in the code? >> >> Best regards. >> >> - Antonio Servetti >> >> ------------------------------------------------------------ >> ------------------ >> Check out the vibrant tech community on one of the world's most >> engaging tech sites, SlashDot.org! http://sdm.link/slashdot >> _______________________________________________ >> Savonet-users mailing list >> Savonet-users@lists.sourceforge.net >> https://lists.sourceforge.net/lists/listinfo/savonet-users >> >> > > ------------------------------------------------------------ > ------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, SlashDot.org! http://sdm.link/slashdot > _______________________________________________ > Savonet-users mailing list > Savonet-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/savonet-users > >
