Subsonic Forum

I've been searching for answers quite a while now, but haven't found anything useful.

I am running 3.7 (build 898) – June 15, 2009

I want to transcode flac to MP3

I have:

Step 1: flac *.wav (I lost the default, which didn't work)
Step 2: lame -v -V 0 -b 96 -B 320 -x - -

This setup doesn't work, what WOULD work?

Thanks for answering.

What version of Subsonic are you running, and what error is it throwing?

I had issues getting transcoding to work until I placed ffmpeg and lame binaries in /var/subsonic/transcode (using the WAR version on OpenSolaris). If Subsonic's not seeing the necessary binaries, that might be why.

Step 1: flac -d -s %s -
Step 2: lame --preset cbr %b -S - -

or

Step 1: ffmpeg -i %s -f wav -ar 44100 -ac 2 -
Step 2: lame --preset cbr %b -S - -

%s - source file (*.flac); %b - bitrate (192 is a good choice)

I'm not sure about version 3.7 but if above examples don't work - post another transcoding row from your version here.

Thanks very much.

flac > mp3 settings

Step 1: flac -d -s %s -
Step 2: lame -v -V 0 -b 96 -B 320 -x - -

Doesn't play the file (through MediaMonkey) but produces a .wav file in the same directory as the .flac file!

Here's the working wma > mp3 steps:

Step 1: wmadec %s
Step 2: lame -v -V 0 -b 96 -B 320 -x - -

My best advice is to:

1) Upgrade to the latest Subsonic version.

2) Use the recommended transcoding settings: http://www.subsonic.org/pages/transcoding.jsp

Sindre

Thank you very much!

It works perfectly. I have one question, however:

The standard de/transcoding settings, will they give you the maximum mp3 bitrate, or do I have to specify that 320 somewhere?

It is still a miracle, how well your software performs. I do like the Subsonic headphones!

PieterB wrote:It works perfectly

That was too quick!

Yes, .flac transcoding works beautiful (how do I get the 'insane' bitrate of 320?)

Yes, native mp3 files play without problems

BUT: all my .wma lossless files DO NOT PLAY AT ALL.
Also: the album count suddenly cuts the database in half: ~ 450 real, count 220

Sounds like that ffmpeg doesn't support wma lossless. If it worked with your previous setup you can change the transcoding settings for wma as follows:

Go to Settings > Transcoding, and specify:
Step 1: wmadec %s
Step 2: lame -b %b --tt %t --ta %a --tl %l -S --resample 44.1 -x - -

Hope this helps,
Sindre

Well, it's funny how solutions are found.

The solution is half your's and half mine:

Step 1: wmadec %s
Step 2: lame -v -V 0 -b 96 -B 320 -x - -

Your solution (lame -b %b --tt %t --ta %a --tl %l -S --resample 44.1 -x - - ) created a horrible 'hiss', with a slight tonal component, meaning that if you know the music, there is a moment that you recognize it -headache included.

By the way: this lame instructions don't work with .flac; How can I force the .flac rendering to be played @320kbps?

PieterB

Glad that it worked.

To hard-code a certain bitrate, just include "-b 320" in the LAME command.

Thanks for the assistance. Just love your program, every day. Functionality, interface, graphical layout...

Thanks for doing this.
