Cannot transcode on Raspberry Pi 2 Model B

[id01]

Hello,

Problem Description: I cannot get transcoding from FLAC to mp3 to work. Mp3 files play normally.
Troubleshooting Steps:

- To begin with, the web interface works, and folders added to "media folders" are visible on the left column of the web interface.
- For the setup I have followed this guide http://mj2p.co.uk/install-subsonic-medi ... pberry-pi/
- I have tried a simple installation of ffmpeg and lame (the same following commands for lame) with

Code: Select all

sudo apt-get install ffmpeg
sudo rm /var/subsonic/transcode/ffmpeg
sudo cp /usr/bin/ffmpeg /var/subsonic/transcode

- The transcoding settings are taken from this page http://www.subsonic.org/pages/transcoding.jsp
- When I try to play a FLAC file, nothing is played. However, I don't see any errors in the log. The log looks like this:

Code: Select all

INFO   PlayQueueInputStream   admin listening to "song.flac"
INFO   TranscodeInputStream   Starting transcoder: [/var/subsonic/transcode/ffmpeg] [-i] [/home/pi/song.flac] [-map] [0:0] [-b:a] [192k] [-v] [0] [-f] [mp3] [-]


- After that I tried to compile ffmpeg manually following this link http://www.jeffreythompson.org/blog/201 ... pberry-pi/
- The problem persists

Any help is appreciated.

I had the same problem while I tried to install the war file under an Apache Tomcat server. I end up figuring out it was simply because Subsonic assumes the executable is in /var/subsonic/transcode/ffmpeg (as shown in your log). I think it won't use the one you've globally installed on your system.

Make a symlink of the file in /var/subsonic/transcode or just download and put it back there. It might help you solve your problem!

Thanks, but I already tried that :/

Code: Select all

➜  ~  sudo ls -la /var/subsonic/transcode                     
total 8
drwxr-xr-x 2 subsonic root 4096 Dec  4 15:38 .
drwxr-x--- 8 subsonic root 4096 Dec  4 15:34 ..
lrwxrwxrwx 1 root     root   15 Dec  4 15:38 ffmpeg -> /usr/bin/ffmpeg
lrwxrwxrwx 1 subsonic root   13 Nov 29 22:28 lame -> /usr/bin/lame

If you're using Jessie, there's a problem with the version of FFmpeg being not compiled properly for Arm6.

I recommend using DietPi (http://dietpi.net) as they have compiled a FFmpeg for Arm6, so if you install Subsonic (using the dietpi software tool) you will get a working solution.
