[k3b] [Bug 479863] Does not finish the burning process of a iso image but the DVD risults burnt without errors
https://bugs.kde.org/show_bug.cgi?id=479863 --- Comment #5 from Paolo Berti --- I did the patch above described to growisofs_mmc.cpp and compiled from source (not easy at all):(https://salsa.debian.org/optical-media-team/dvd-rw-tools). The resulted growisofs executable, placed in /usr/bin/, worked well without any error while burning the iso file.

https://bugs.kde.org/show_bug.cgi?id=479863 --- Comment #3 from Paolo Berti --- WORK AROUND FOR THE K3b problem: hang at the end of DVD-R[W] DAO recording. The problem was observed with image sizes not divisible by 32KB. It manifests itself as I/O error in the last WRITE command, which is caused by latter's timeout. The recording per se is properly completed by unit and no data loss occurs. To work around the timeout condition, pad input image file up to the nearest 32KB boundary or avoid DAO recordings. One way to pad is to: perl -e '$blk=32*1024; $nm=@ARGV[0]; $sz=(stat($nm))[7]; truncate($nm,int(($sz+$blk-1)/$blk)*$blk);' example.iso (ref: http://fy.chalmers.se/~appro/linux/DVD+RW/hcn.html) IT WORKED FOR ME!!! HELP FOR A RESOLVE The bug is described and a diagnosis is given here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794868 It gives this patch to the growisofs_mmc.cpp file as a definitive solution: - if (!(errcode=cmd.transport (WRITE,(void *)buff,size))) + if (!(errcode=cmd.transport (WRITE,(void *)buff,nbl*2048))) break; In the source package of dvd+rw-7.1-14build1 (used by Ubuntu 20.04.6), the file growisofs_mmc.cpp, at line n. 527, has exactly: if (!(errcode=cmd.transport (WRITE,(void *)buff,size))) So, corrected as above can resolve the bug. I am not a c++ expert and am not able to do it by my self. -- You are receiving this mail because: You are watching all bug changes.
