pCD has long delay before playing CD (Solved)

Post by greengeek »

I am using zigbert's pCD cd player (currently using Tahr 32) and experiencing a long delay before it will start playing an audio CD.

I have a suspicion that this may be due to freedb database having gone offline earlier this year and I would like to update the pCD utility with the gnudb.org database address that fredx181 recently brought to my attention as the new database location for rippers etc.

Does anyone know where the correct config file is for pCD please? (Or is freedb.org specified within the code itself?)

cheers!

ps: /usr/local/pcd/func seems to contain code for cddb lookup but I cant see freedb.org coded in there anywhere...

EDIT : pCD seems to contain a ripping function so I am wondering if pCD relies on something already coded into cdda2wav - maybe the freedb.org address is specified somewhere outside of pCD.

It seems that freedb.org is compiled into cdda2wav but can be overwritten by the cddb-server parameter at run time.
If pCD is calling cdda2wav than maybe this parameter needs to be passed by pCD to cdda2wav. Unless there is some way to set an environmental variable permanently for cdda2wav.

Here is an example of the syntax that seems to work to get cdda2wav to access the database:

root# cdda2wav dev=/dev/sr0 cddb=0 -cddbp-server=gnudb.gnudb.org

cdda2wav: Read TOC CD Text failed (probably not supported).

Got it!
Had to modify /usr/local/pcd/func around line 40

Change:

Code: Select all

cdda2wav dev=$DEVICE -cddb=1 -info-only -no-infofile > $WORKDIR/pcd-cddb 2>&1 &

to

Code: Select all

cdda2wav dev=$DEVICE -cddb=1 -cddbp-server=gnudb.gnudb.org -info-only -no-infofile > $WORKDIR/pcd-cddb 2>&1 &

@greengeek :-

Ian:-

I believe if you look in /usr/share/glib-2.0/schemes, you may find an XML file for freedb.org. I'm not saying it's relevant to your situation, but it may be worth investigating?

Mike. ;)

Hmmm, i am currently testing a Tahr32 and i don't see anything here for freedb on my version. Here is the list of files i see there:
(maybe there is an entry within one of those files...)

Code: Select all

10_gsettings-desktop-schemas.gschema.override
10_libgtk-3-common.gschema.override
app.gtkhash.gschema.xml
gschemas.compiled
org.gnome.desktop.a11y.applications.gschema.xml
org.gnome.desktop.a11y.gschema.xml
org.gnome.desktop.a11y.keyboard.gschema.xml

It would be nice if it was simple to set a global file that could redirect freedb to gnudb - but i suspect a more piecemeal approach may be needed. I did hear back from Heiko regarding the best way to get cdda2wav updated and i have posted his reply here
