*** Bug 120790 has been marked as a duplicate of this bug. ***

The dvd patch seems to screw up the commandline argument handling.  I
can't burn a bin/cue with the current RPM. (cdrecord-2.01-0.a27.2)

# cdrecord -v dev=/dev/hdc -dao cuefile=foo.cue
cdrecord-2.01-0.a27.2
cdrecord: No tracks specified. Need at least one.
Usage: cdrecord [options] track1...trackn
...

Recompiling it without the dvd patch makes it work.

djh, I think your problem is different from what we have here, please
open an own Bugzilla entry.

I ran cdrecord from a debugger and found that it tries to set the
speed as specified on the command line in speed_select_mmc() -- so no
wrong command line parsing here:

--- 8< --- cdrecord/drv_mmc.c ---
[...]
LOCAL   int     curspeed = 1;
[...]
LOCAL int
speed_select_mmc(scgp, dp, speedp)
        SCSI    *scgp;
        cdr_t   *dp;
        int     *speedp;
{
[...]
        if (speedp)
                curspeed = *speedp;
[...]
        /*
         * 44100 * 2 * 2 =  176400 bytes/s
         *
         * The right formula would be:
         * tmp = (((long)curspeed) * 1764) / 10;
         *
         * But the standard is rounding the wrong way.
         * Furtunately rounding down is guaranteed.
         */
        val = curspeed*177;
        if (val > 0xFFFF)
                val = 0xFFFF;
        if (mmc_isyamaha(scgp) && forcespeed) {
                if (force_speed_yamaha(scgp, -1, val) < 0)
                        return (-1);
        } else if (mmc_set_speed(scgp, -1, val, ROTCTL_CLV) < 0) {
                return (-1);
        }
                                                                     
                                                                     
                    
        if (scsi_get_speed(scgp, 0, &val) >= 0) {
                if (val > 0) {
                        curspeed = val / 176;
                        *speedp = curspeed;
                }
        }
        return (0);
}
[...]
--- >8 -------------------------

I saw that curspeed == 2 until it is set in "curspeed=val/176" above,
i.e. the speed gets set with mmc_set_speed(), but the drive seems to
ignore the setting (or one of mmc_{set,get}_speed() is buggy in that
regard) and returns a different value in mmv_get_speed() which sets
curspeed=10.

I have noticed a mistake in cdrtools-2.01a27-dvd.patch, there is a
missing comma between arguments.

"formattype&pktsize#" should be "formattype&,pktsize#"

The bug results in many options not getting parsed (like cuefile or
dao/sao).

I have also notified warly

cool! Thank you very much!

Warly has fixed the missing comma in his dvd patch; the patch filename
did not change.

http://peoples.mandrakesoft.com/~warly/files/cdrtools/archives/cdrtools-2.01a27-dvd.patch.bz2

The speed, cuefile, dao/sao and other options seem to behave now.

Enjoy,

already submitted a fixed package in the buildsystem, will soon appear
on rawhide..
