any luck transcoding from lossless AAC to any other format?

Post by cacasododom » Sat Oct 24, 2009 9:27 pm

Guys,
I'm streaming audio using TwonkyMediaServer on my MacBook to my Pioneer SC-25 AV receiver. Twonky streams all formats nicely except for my Apple Lossless files. Also, the Pioneer doesn't except lossless AAC, so I'll need to transcode to another format. I've tried transcoding the lossless AAC files to flac using ffmpeg. At a terminal prompt, this conversion works well using a command like this:

Code: Select all

ffmpeg -i $infile -acodec flac $outfile
I can play the outfile just fine using VLC on the Mac. However, trying to get TwonkyMS to convert the lossless to another format acceptable to the Pioneer doesn't work. The Pioneer accepts mp3, wav, flac or normal AAC files. So, it would be helpful if anyone has had luck converting from lossless to one of those.

My desc file for the flac conversion looks like this:

Code: Select all

MACLT:cgi-bin sodo$ cat /Users/sodo/ffmpeg-m4a-flac.desc
# transcode audio (m4a to flac)
#(c) 2008 by PacketVideo
exec: ffmpeg -i $infile -acodec flac $outfile 2>/dev/null 
# capabilities
from=audio/x-m4a
to=audio/x-flac
asynchronous
priority=idle
I've tried a couple other conversions, from lossless AAC to mp3/wav to no avail.

Has anyone had any luck using TwonkyMediaServer to transcode lossless AAC files to ANY other format (flac/mp3/wav preferred)?

thanks.

Just for kicks, I installed the Linux version of Twonky. The transcode still did not work.

I had thought the Pioneer did not play the lossless AAC files, but I double-checked the documentation and indeed it does. Also, I verified that it plays lossless AAC by hooking up my iTouch directly to the receiver and the receiver does play the lossless files.

Searching the net, I ended up downloading EyeConnect (http://www.elgato.com/elgato/na/mainmen ... ct.en.html) which supposedly plays lossless AACs. I was pleasantly surprised to find that it worked. Now I can play my lossless AAC music library. Hooray.

Sorry Twonky.
