Hi,
Surprise: growisofs does not inspect the ISO with BD-R profile 0x41 !
So adding MEDIA_BD_R_SRM_POW will not be correct.
Do Not Commit, Please.
I rather see in growisofs_mmc.cpp a special handling for pseudo-overwritable
BD-R which i did not remember to have seen in the SCSI MMC related code
of K3B:
cmd[0] = 0x52; // READ TRACK INFORMATION
cmd[1] = 1;
cmd[4] = next_track>>8;
cmd[5] = next_track; // ask for last track
cmd[8] = sizeof(buf);
cmd[9] = 0;
err = cmd.transport (READ,buf,sizeof(buf));
...
if (mmc_profile==0x41 && bdr_plus_pow && buf[7]&1) // NWA_V
{ next_session = buf[12]<<24;
next_session |= buf[13]<<16;
next_session |= buf[14]<<8;
next_session |= buf[15];
}
else
{ next_session = buf[8]<<24; // Track Start Address
next_session |= buf[9]<<16;
next_session |= buf[10]<<8;
next_session |= buf[11];
}
The first case is for what K3B recognizes as MEDIA_BD_R_SRM_POW.
I will now revisit the code of K3B which asks the drive for the
Next Writable Address.
Have a nice day :)
Thomas
