Transcoding Apple Lossless To Play On PS3

Dear All,

I have posted a support ticket about this, but Twonky support has not deigned to reply to date.

I am trying to play apple lossless (ALAC) format files on the PS3, using the transcoding feature of Twonky (which is hosted on a Mac Mini). I have made the entry for M4A in the transcoding DB, pointed the mplayer location file to the binary, run the command-line through the binary (to check it works), and created a desc file for the transcoding.

The PS3 fails to recognise the file, although the file and tags appear correctly on the PS3. When you try to play the file, it gives an error regarding unsupported format.

Has anybody managed to get transcoding of apple lossless files working correctly on Twonky?

Kind Regards,

I am trying to do something similar with ALAC - WAV. My music collection is apple lossless. ALAC files are in M4A extension. However I am stuck and I can't get it to work. I have upgraded my WD Worldbook I (whitelight) with Twonky 7.0.9 Special NAS using this guide ... book-world
This is what I have done so far.

Used putty to SSH WD mybook world's IP

ipkg install alac-decoder (downloaded and installed alac-decoder 0.1.0-2)
alac decoder installed to /opt/bin/alac

I have created alac-wav.desc in /usr/local/twonky/cgi-bin/

#transcode audio
exec: alac $infile -f output.wav $outfile

I have also created alac.location in /usr/local/twonky/cgi-bin/


I made both files executable
chmod +x /usr/local/twonky/cgi-bin/alac-wav.desc
chmod +x /usr/local/twonky/cgi-bin/alac.location

in /usr/local/twonky/resources/transcoding.db I have added this under #Additional audio res


I have cleared the cache and restarted twonky server. I am very new to putty coding and don't know where I have gone wrong or how to fix. Can anyone help?

1st big question is (I dont have any alac files, will try and create one)

How do we know that alca files are identified as audio/mp4a?

Also, take a look at my two replies here ... 607#p41607
