I got cued to build with the cdtext changes in 0.90 (git) but I have not tested, yet. I will get to testing sometime this week. Thank you for the quick reply!

Hi Rob,

first of all, there are nearly no commercial disks, that have
multilanguage CD-Text.

Some questions about the new cdtext interface.

Do I need to set the language? What language will I get if I do not
set the language? Is there a default language? Will it return the

Default is the first language on the disc (block 0).

Does asking for track 0 still return the disc-level cdtext?

Yes. The main difference is, that you now have one structure for the
whole disc.

When does libcdio read the cdtext on a real disc? Is this part of
the TOC parsing? What function call is going to trigger reading the

Calling cdio_get_cdtext the first time will trigger the reading and
caching. It is not part of the TOC parsing. You have to call it
manually. If you are interested in the mmc, look at
mmc_read_cdtext_private in mmc/mmc.c.

cdio_get_cdtext calls cdio_get_cdtext_raw, which you can do yourself if
you are interested int the binary data.

I am asking in the interest of expediting my testing of the upcoming
release. If I do not get answers quickly, I will refer to the code.

Thank you.


Thank YOU!
