*** This has worked great for me with Subsonic v4.5. I have not been able to get this working in Subsonic v4.6 ***
*** If somebody figures out how to make this work in v4.6, I'd love to know the solution ***

I use my Subsonic server primarily in Jukebox mode, but this also works for streaming via flash player. The disadvantage to using this method is that SHOUTcast playlists must be downloaded to your Subsonic server. This is, however, better than the alternative of not being able to stream SHOUTcast stations via Subsonic.

This is achieved by using a program (mpg123) to convert the SHOUTcast stream to raw PCM, then using LAME to re-encode the PCM audio back to mp3 in real-time. Playlists are saved locally as ".radio" files so that they show up in the web interface as ordinary music files, and so they don't conflict with the way Subsonic handles .pls files (as playlists).

These instructions are for Debian.

Step 1: Download mpg123

Code: Select all

apt-get install mpg123

Step 2: Symlink mpg123 into the Subsonic transcode directory

Code: Select all

ln -s /usr/bin/mpg123 /var/subsonic/transcode/mpg123

Step 3: Go into Subsonic Settings -> Transcoding and add a new transcoding option:

Code: Select all

Name: radio > mp3
Convert from: radio
Convert to: mp3
Step 1: mpg123 -q -s -@ %s
Step 2: lame -b %b --tt %t --ta %l --tl %l -r -S --resample 44.1 - -

Step 4: Enable this transcoding option under Settings -> Players

Step 5: Add ".radio" to the Music mask field under Settings -> General

Subsonic should now transcode ".radio" files into a format that can be streamed through any of its players. ".radio" files are simply .pls files that have been saved locally. You can change the extension to whatever you want as long as you also change the extension in the above steps. I chose to use ".radio" as to not conflict with .pls (playlists) that Subsonic already recognizes.

--------------------

Now you can download .pls files (SHOUTcast stream playlists), rename them to ".radio", and place them in an accessible folder on your Subsonic server.

For instance, on my server, I have a directory "/inet-radio" that I've added into Settings -> Media folders. I can either copy .pls files from my computer into that folder and rename them, or I can use a tool like wget to download playlists directly to the folder.

Here's an example of using wget to download the Digitally Imported Vocal Trance pls file, and place it into my inet-radio folder with the proper .radio extension.

Code: Select all

wget --output-document /inet-radio/Vocal-Trance.radio http://listen.di.fm/public3/vocaltrance.pls

These playlists now show up in Subsonic just like any other audio file. They will play in both Jukebox and flash player modes. I've also successfully streamed stations to my Android phone using the Subsonic mobile app.

I can confirm I have gotten this to work with 4.6 (under Windows) I *suspect* the issue may simply be adding:

Step 5: Add "radio" to the Music mask field under Settings -> General (remove the leading . )

These instructions are for Windows.

Step 1: Download mpg123

http://www.mpg123.de/download/win32 -> mpg123-1.14.2-static-x86.zip

Step 2: Copy mpg123 into the Subsonic transcode directory

C:\pathto\subsonic\transcode\mpg123.exe

Step 3: Go into Subsonic Settings -> Transcoding and add a new transcoding option:

Code: Select all

Name: radio > mp3
Convert from: radio
Convert to: mp3
Step 1: mpg123 -q -s -@ %s
Step 2: lame -b %b --tt %t --ta %l --tl %l -r -S --resample 44.1 - -

Step 4: Enable this transcoding option under Settings -> Players

Step 5: Add "radio" to the Music mask field under Settings -> General (remove the leading . )

Many thanks to EnergyCoffee for the original solution

Did you guys get these streams to play in the Android Subsonic client? Mine plays ok in the web player unless the flash player catches up with the stream and just stops playing. The Android client plays like 1 second of the station then acts like it downloaded/cached the song/station so not a true stream. It would probably be easier to just use a Shoutcast player for your phone but I wanted to transcode it to a lower bitrate if the stream doesn't have any <128kbps.

/var/subsonic/transcode/radio.sh

Code: Select all

wget -q -O - -i "$1" | cut -d "=" -f 2 | grep "^http://" | sort -R | xargs -L 1 wget -q -O -

chmod X attribute to create script executable!

Transcoding: radio-mp3 | radio | mp3 | radio.sh %s
Settings/General: add "radio" to "Music files"... if you need add second step to transcode to some bitrate.

example.radio file

Code: Select all

Hi,
Does it still work with 4.8 windows? Sounds great if its would working.

I have setup how it was described, but it don't works.

If i remove the phase 2 (lame encoding) , the flashplayer's "seconds counter" run very fast, I think because the input RAW stream.

When i add the second phase lame encoding again, it seems that the stream is played, but the "second counter" freezed at 0 seconds...

[02.12.13 11:47:30 MEZ] WARN StreamController Unknown duration for Radio - Chillout Dreams. Unable to estimate transcoded size.
[02.12.13 11:47:30 MEZ] INFO PlayQueueInputStream lolomm listening to "radio\Radio - Chillout Dreams.radio"

[02.12.13 11:47:30 MEZ] WARN TranscodingService Failed to transcode Radio - Chillout Dreams. Using original.

EDIT:

i modifies the second phase encoding:
lame -b %b -r -S --resample 44.1 - -

now it works.....

Hi,

I know this is an old thread, but I hope someone is still "listening". Thanks for providing this great solution, it still works like a charm in version 5.2.1. There is, however, one thing I can't seem to figure out. Most .pls files play great after going through the 2 step conversion describes, but there are a few that play at double speed (or at least way too fast..) after the conversion. I tried changing the sample rate, but that did not help. Did any one else gave this problem and is there a known solution perhaps?
KInd regards,
Santi
