Default REACAST codec question

Hello,

I managed to install an ICECAST server on my Synology NAS.
Reaper is streaming to this server successfully.

When I open the stream with vlc to check the kind of codec used, I see: "MPEG audio layer 1/2 (mpga)". My understanding is that it is not mp3.

I know that ICECAST allows to stream FLAC, and I would like to try that.

I don't know who is deciding the used codec. Is it REACAST plugin or ICECAST configuration?

Can anyone help me?

Thanks!

I can now answer my own question if anybody is interested.
It is reacast which dictates the used codec on the stream.

But how do you set what codec to use? reacast has no setting to choose between codecs.

you cannot choose the streaming format. You can only choose sample rate and bit rate. I thought having read somewhere that it would stream in vorbis or opus but when I record the stream with streamwriter, I get mp3 files (streamwriter set to record in original format). Maybe VLC converts to other formats on-the-fly. Btw, mpa files are MP2 files (MPEG-1 layer 2) which is often used on DVDs and for Digital Video Broadcast via satellite. MP3 is MPEG-1 layer 3.

I made a feature request. Never done that before - is that the proper way to go about it?

FR is ok, however, not all formats can go beyond 320 kbps. I also wonder wether something else will produce a significantly better audio quality than MP3 at 320 kbps. Generally, 320 kbps is considered transparent even for pro listeners. I'd still be happy to have a format choice, though. OPUS is optimized for streaming and produces better quality than MP3 with less bits. Not every peer enjoys high speed internet.

for me, it is more about getting the same quality as 320kbps mp3, but at a lower bitrate.

aac 256kbps is roughly equivalent to mp3 at 320kbps I think.

opus looks good, but is it well supported or still emerging?

support for established formats like aac or ogg would be nice until opus becomes more standard.
