Sony ATRAC3 decoder plugin for .rmj files

**zorkerz** · October 4th, 2008

I have what I was lead to believe is a music album that contains .rmj files.

Totem gives this error.

An error occurred
The playback of this movie requires a Sony ATRAC3 decoder plugin which is not installed.

Im not finding much about this. Has anyone run into files like this before? Is there any chance I will be able to find a decoder for them?

One of my albums gives me that error message in Totem Movie Player (gstreamer). When Totem tries to search for suitable plugins, it comes back and says there aren't any. I was going to say that ATRAC3 is an inferior, proprietary format without Linux support, but the songs that give me that error will play for me using VLC Media Player and Gnome MPlayer. I don't know what other packages I installed that make that happen: maybe gstreamer good, bad and ugly.

Hi mdmcginn.

Helix and mplayer are supposed to read this .

I have had a look and certainly the svn MPlayer can play these files. I downloaded the following sample:

Code:

wget http://samples.mplayerhq.hu/A-codecs/ATRAC3/sample.ATRAC3.66kbps.44100Hz.Stereo.wav

and the svn MPlayer used ffatrc from libavcodec to decode:

Code:

andrew@skamandros~/Desktop$ mplayer sample.ATRAC3.66kbps.44100Hz.Stereo.wav 
MPlayer SVN-r29351-4.2.4 (C) 2000-2009 MPlayer Team

There is also a windows codec available:

atrac3      acm       problems  Sony ATRAC3  [atrac3.acm]

but as predicted above this external codec (-ac atrac3) crashed MPlayer completely

.

Edit: Mind you I could not found any such samples in Real Media Jukebox format...

Indeed I am connected. When pressing the button I get:

"No packages with the requested plugins found

The requested plugins are:
