Success! MediaTomb Transcoding Music On a NAS

boilerjt · Sep 28, 2008

It is confirmed :joy: Audio transcoding is possible from a NAS Box.

NAS: D-Link DNS-323 (500MHz ARM CPU, 64MB RAM) with two 1TB Seagate ST31000340AS SATA Drives
MediaTomb SVN-1895 Pre-0.12.0 code (compiled on the NAS)

I have been able to get music, video, and photos to stream to my HR20-700.

Music - MP3, Flac, Ogg, AAC, M4A, WMA Real Time Transcoded to WAV.
Video - MPEG2 (.mpg), TS Not Transcoded. VOB (Video Track & Audio Track 1) Transcoded (Muxed) from PS to TS
Photos - JPEG, Real Time Transcoded to strip metadata before sending to HR20.
Online Audio Streams: Will play MP3 and MMS streams in a playlist.

When transcoding Music, here are the CPU usage percentages:
MP3: 14%
AAC, M4A: 20%
Flac: 8%
Ogg Vorbis: 25%
WMA: 11%

These are a lot better than I anticipated and do not interfere with normal NAS file sharing.

Before you ask, it was a royal PITA to compile MediaTomb (and half of the dependencies) directly on the NAS. Please don't ask for a How-To on how I got this to compile. I probably couldn't reproduce it anyway

This is just a proof of concept that a NAS box is powerful enough to transcode audio. I was just impatient to see if this would work and couldn't wait for the official release when pre-compiled binaries would be available.

I will provide a How-To on how to setup this NAS (to get shell access) and how to install/setup MediaTomb with a pre-compiled install. Also, I have no idea when the 0.12.0 will be released. The MediaTomb developer has been tight lipped lately.

UPDATE: I have now packaged the software for installation on the DNS-323. Instructions and download links are here:

Care to share your config.xml?

I'm trying to get Mediatomb running on my FreeBSD machine. Finally got it to install and it's running but I have X's next to file names on my HR2X's.

Thanks boilerjt! Got it working perfectly!

My transcoding settings were off.

Now to get Video working. :lol:

I have mpeg video working now.

And I'm working my way thru the monster "Mediatomb is now working" thread hoping to get wmv and avi working as well. :lol:

Just curious...what kind of hardware are you running FreeBSD? As far as video transcoding goes, the ffmpegvideo script will transcode just about format

You may have to compile a custom ffmpeg and you'll need to install mediainfo... Also, Greg Lee is working on a new script using VLC.

I'm running it on an i386 machine.

I have ffmpeg installed, from ports, but I get errors on avi and wmv formats.

When I try to play an avi or wmv file I get:

2008-09-28 20:57:58 INFO: Arguments: %in %out 5900k 256k
2008-09-28 20:57:58 ERROR: process terminated early

Do you have mediainfo installed? The first thing the script does is call mediainfo to get information about the video. Other things to check are that the ffmpegvideo +x bit is set (chmod +x) and whether the script actually runs without errors. I don't know if the script runs on FreeBSD the way it runs on Linux.

You can test the script by running it from the command line (ffmpegvideo inputfile.avi outputfile.ts 5900k 256k) and see if it transcodes and writes to the specified output file. If any errors occur, they should be sent to the console.

Ok, this is odd... I'm getting "command not found" but I know ffmpegvideo is in /usr/local/bin and set executable.

Yes, mediainfo is installed and responding. And ffmpeg is installed and working as well.

Are you using a bash shell? The script calls /bin/bash and you should make sure this is correct.

You know, I should have noticed that. Duh!

I changed it to /usr/local/bin/bash and now avi's and wmv's work.

Thanks again boilerjt!
