Hi,
i have tried to update my cd-player plugin for the Linux-VDR
(http://www.uli-eckhardt.de/vdr/cdplayer.en.shtml) to the new API of
libcdio 0.84. I have tested this problem with a current 64Bit OpenSUSE
12.2.
I use the following code to access the cd-text information:
#if LIBCDIO_VERSION_NUM > 83
pCdio = cdio_open(FileName.c_str(), DRIVER_UNKNOWN);
#else
pCdio = cdio_open(FileName.c_str(), DRIVER_DEVICE);
#endif
if (pCdio == NULL) {
mState = BCDIO_FAILED;
txt = tr("Can not open");
mErrtxt = txt + " " + FileName;
esyslog("%s %d Can not open %s", __FILE__, __LINE__,
FileName.c_str());
return false;
}
#if LIBCDIO_VERSION_NUM > 83
pCdioCdtext = cdio_get_cdtext(pCdio);
if (pCdioCdtext == NULL) {
dsyslog ("No CD-Text available");
}
#endif
cdio_get_cdtext returns here always NULL, even if the CD has cd-text
information. I have performed a test with cd-info and there the same
problems seems to exist.
The output of the old cd-info 0.83:
