Hi,
i am developer of libburn and wonder since years why K3B ignores
programs based on it.
cdrskin and xorriso burn CD, DVD, and BD just fine.
The only shortcomming towards wodim and cdrecord is with exotic CD layouts
like mixed mode or "raw" writing. (I lack of test cases and of the will
to get into trouble with copyright holders of cloned CDs.)
@Leslie Zhai:
I am willing to help. Not only with adapting to cdrskin but also with
identifying problems in growisofs.
Isn't your patch
"Use cdrecord for burning blueray instead of wodim."
http://commits.kde.org/k3b/fcb0ff1f36c319fd1e2b4bd92c2c08fdc690212c
mislabelled ?
Shouldn't it rather be
"Use cdrecord for burning blueray and DVD instead of growisofs"
?
Well, cdrecord and libburn are both living projects, in contrast to
growisofs and wodim. So this choice is not unreasonable on the first
hand.
Nevertheless you should be aware that growisofs has the better
understanding of DVD as specified in MMC-5/MMC-6. Its BD code has
a few flaws, indeed. Some have been fixed in the last 8 years by
distro patches.
So i advise to keep growisofs as default at least for DVD media if
you cannot get yourself to give cdrskin a try.
On BD media, cdrecord does not format BD-R (which is good for burn
speed) but cannot employ Streaming mode on BD-RE (which is bad for
burn speed).
cdrskin can format BD-R if desired, which yields checkreading during
burn and slow burning speed. It can also disable checkreading on
formatted media. The latter makes 2x BD-RE burn with 2x effective speed
instead of 0.8x to 1.0x speed.
(Looking at libk3bdevice/k3bdevice.cpp line 3611 i wonder why K3B
is diving into MMC entrails instead of letting the burn program
determine the disc state. Does K3B have own MMC expertise ?)
Have a nice day :)
Thomas
