Transcoding FLAC to WAV?

[Ron Olsen]

Here's how to get mediatomb running on VortexBox 1.6/F14:


1. Login to your VortexBox as root.


2. Execute the following commands:





rpm –e mp4v2 libmp4v2-0


yum ––disablerepo=vortexbox install mediatomb



3. Edit /etc/mediatomb.conf and change


MT_INTERFACE="NOT_SET"


to


MT_INTERFACE="eth0″


4. Enter



service mediatomb start



5. In your web browser, go to http://vortexbox:50500 to get the mediatomb web interface.


6. On the mediatomb web interface, setup mediatomb to use the /storage directory:


Click on Filesystem


Click on /storage


Click on "+ (add)" or "+ (Add as autoscan dir)"


7. mediatomb should now be available on your uPnP control device.


8. If you want to mediatomb to autostart on reboot:

chkconfig mediatomb on

9. You may also need to edit /etc/mediatomb/config.xml to get the appropriate transcodings that you want.


10. Enter

man mediatomb

for more info.

/usr/share/doc/mediatomb-0.12.1/README has detailed user info.



I have tested this with an iPad using the AirPlayer app to play music (FLAC and mp3) from my VortexBox library on the iPad.


Caution: removing the mp4v2 and libmp4v2-0 packages may impact other VortexBox features, but I'm not sure for what mp4v2 and libmp4v2-0 are needed. VortexBox Player seems to work OK without them.


Also, removing libmp4v2-0 and installing libmp4v2 causes problems with the VortexBox update process: yum update wants to reinstall libmp4v2-0, but cannot since libmp4v2 is needed by mediatomb. If you update from the command line, use



yum ––skip-broken update



instead of



yum update
Updates from the VB GUI should be OK, since it uses the "––skip-broken" option.

Hi Ron,




Many thanks, I now understand why is was complaining about versions of those files.


I might explore using this tool, it offer other options comparied to the miniDLNA tool.


AJ, you could have both running if you want or turn off the miniDNLA (the web interface has an option for that).




Cheers,


James

libmp4v2 is used to mirror FLAC to Apple lossless files. It's weird that Fedora is still using such an old version of libmp4v2. Seems like this Ron's hack will work.

Hi Ron,


Many thanks, I will have a look at the transcoding option to see if this is a good solution for FLAC to MP3 on the fly.


Perhaps this is another 'document' to add to the list for PS3 owners.


I will certainly mention it to my son for his systems!




Cheers,

Hi Ron,




Thanks for the post. I'll try installing mediatomb using your instructions and report back to the group.


I recall reading somewher that the PS3 required data in bigendian form, I wonder if this is built into mediatomb?




Regards.

Hi James,



Thanks for the suggestion. I'll try mediatomb using Ron's instructions when I have some free time. My interest is in FLAC-> Wav transcoding.




Regards.

I fixed all the dep problems with mediatomb you can now just do a



yum install mediatomb

Hi Guys,




Cool! Testing out with Foobar2000 and its UPnP addon and it works well.


So I can now serve MP3 to Foobar, still not worked out how it will work with the TV.


Foobar would be a simple was to test the process.


When you change the config.xml file and using foobar (you need to download


and install the UPnP Dll) you can work out which encoding process it uses.


Using stuff on the web I can transcode with ease to foobar from Flac to flac,


flac to mp3 and flac to raw.


My flac to mp3 used a simple script.




#!/bin/bash
flac -d -c "$1" | lame --id3v1-only -t --preset insane - - > "$2"


and I am sure you can do the same for the flac to wav.




For all the other formats and tesing you may need to install VLC


to use FLAC to PCM coversions with few changes to the /etc/config.xml.




yum install VLC

Have a fiddle with the config.xml file.


any errors with stop mediatomb starting and are in the log file.


If you dont like the name mediatomb you can also change it in the same place.




Have fun......


Thanks Ron and Andrew for helping to sort out why it would not install.




Cheers,


James

Converting FLAC to WAV is not so difficult as long as we get the right way.

Just choose a detailed guide you prefer to use.
