Subsonic Forum

Posted: **Fri Dec 09, 2011 2:14 am**

Ever since the default transocding for all music files has been converted to one step:
ffmpeg -i %s -ab %bk -v 0 -f mp3 -

I've been unable to successfully transcode flac files to mp3 with the above command.
However, if I don't pipe ffmpeg to stdout then I am able to play the resulting mp3 file.
An example of this would be:
ffmpeg -i flac_file.flac -ab 128k -v 0 -f mp3 ./test.mp3

But, I am able to successfully transcode other file types(such as .m4a) w/ subsonic. I'm a little stuck and would appreciate some help!

Here are the log files for each scenario:

FWIW i couldnt get ffmpeg to encode with mp3 on my freenas server

so i switched back to the 2 step transcoding method (its on this website somewhere on how to do it)

then i used at 64bit amd lame build also linked on this forum with the following settings which work

step 1
ffmpeg -i %s -v 0 -f wav -

Step 2
lame -V 0 --tt %t --ta %a --tl %l -S --resample 44.1 - -

this might be the long way to fix the problem but any other doesnt seem very obvious to me

Reverting back to the old 2 stage commands fixed the problem for now.
I do have a custom build of ffmpeg. Maybe I have a bad build.

I wasn't able to find any ffmpeg specific builds for subsonic? Sindre said that ffmpeg comes bundles with subsonic.
I'm running Ubuntu, so I'm assuming subsonic just does an apt-get? Maybe I'll try re-installing...

@ skidelo
i believe for the linux releases you need to get it yourself, i had to compile my ffmpeg for my freenas box if i recall correctly

Posted: **Wed Dec 14, 2011 8:16 pm**

funnily enough i've moved from freenas too ubuntu because i kept running into anoying issues with freenas which couldnt quickly and easily be resolved asits not a full distro

in ubuntu just apt get lame flac ffmpeg etc and install and it all works perfectly even with the one step default settings, unlike freenas.

freenas is my backup on a sd card though just incase things get fried.

I ended up wiping my computer and re-installing subsonic via the debian file. This time I noticed that the transcoding folder already had its own binaries of ffmpeg and lame in it. But no cigar! Still the same problem of not being able to stream flac files. Changing to the 2 step method still fixed the problem.

I tried installing the ubuntu packaged ffmpeg and lame, but these binaries couldn't play flac or m4a files. Maybe I'm missing a library? Anyway, small problem... but if anyone knows a fix, it would be nice :-)
