Subsonic Forum

Hi, I'm new to subsonic. I installed Subsonic on my server, it plays fine mp3 but not FLAC

Here is my log :

Any help would be appreciated, thanks !

It puts the same thing for all FLAC files.

up!

I guess you haven't changed any of your transcoding settings in subsonic, right? cause it seems it's trying to use the default ffmpeg codec.
if you want to play flac files I suggest you to use a two step encodig method, first convert the flac to wav, then convert the wav to mp3.

to do this you should get the latest lame and flac codecs.

if you're on debian you can do this with

sudo apt-get install flac
sudo apt-get install lame (I just went through this configuration process on a raspberry pi, and I had to reinstall lame there to get it work, at least I guess I had to)

then you should link the codecs to your subsonic/transcode directory
sudo ln -s /usr/bin/flac /var/subsonic/transcode
sudo ln -s /usr/bin/lame /var/subsonic/transcode

now that you have the codecs you can configure subsonic
go to settings > transcoding and take the first record "mp3 audio"
copy the following to step 1: flac -c -d -F %s
and put this to step 2: lame -V 0 --vbr-new - -

this will also give you the best possible quality you can get while you stream your lossless files.

let me know if it works, cheers!

*edit: updated my post. ln -a instead of cp is more practical.

Thanks! This worked for me

couple of things to complete your answer...

actually, ffmpeg can transcode flac, and it can do it in 1 step. The default subsonic transcode command works perfectly !

This method is not recommended ; by doing so, you physically copy the binary into the subsonic directory ; when your distro is going to update those, subsonic will still be using the old, deprecated version. You're better off creating a symbolic link :

Code: Select all

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

if you absolutely want to use the 2-step transcode, just do the same for flac and lame

Yea, a symbolic link is definitely a better way to add the codecs, true.
But ffmped didn't work for me either, maybe a reinstall could have solved that, but the two step conversion is also more transparent (at least to me) and the lame codec is kind of a standard when it comes to audio encoding

Thanks, the two steps method works great ! Don't know why the default method doesn't !

Resolved !

Glad to hear! I think if you delete the ffmpeg codec which comes with subsonic, reinstall it from repository and link the new one to the transcode folder it should work.

This is a ONE STEP method for FLAC to CBR MP3 that works great, correctly preserves tags, obeys Subsonic player bit-rates, and down-samples to 44.1KHz/16bit/stereo. Optimized and tested with Subsonic 4.7, Winamp 5.63, N7 Player (Android).

Code: Select all

ffmpeg -i %s -ar 44100 -ac 2 -request_sample_fmt s16 -acodec libmp3lame -ab %bk -map_metadata 0:0 -f mp3 -id3v2_version 3 -

Try it if you want...

Can you set it to encode to VBR instead of CBR?

Sure, but you're going to need a newer FFMPEG binary on your system that supports the transcoding you want. First, look here, then decide what your target "quality" should be. Once you have that decided, put the new FFMPEG binary in your transcode folder (backup the original). Then update your transcoding string like the example below, "-q:a x", where x is the VBR quality level you want. Good luck, but it's actually pretty easy.

Code: Select all

ffmpeg -i %s -ar 44100 -ac 2 -request_sample_fmt s16 -acodec libmp3lame -q:a 0 -map_metadata 0:g:0 -f mp3 -id3v2_version 3 -
