Description
-------

Hi KDE developers,

tempDir was defined as `QScopedPointer<QTemporaryDir>` https://github.com/KDE/k3b/commit/05cd636c9dfb35fdeea666b581c1f2b9c3820a90#diff-920d85bf84619674590c2e13a0428d00R40 it is easy to create a unique directory for temporary use, and QScopedPointer's destructor will free the allocated memory automatically, brain-free :)

but it still mkdir all parenets directories in complicated way https://github.com/KDE/k3b/commit/05cd636c9dfb35fdeea666b581c1f2b9c3820a90#diff-920d85bf84619674590c2e13a0428d00R113

so I just mkpath for temporary `VIDEO_TS` directory and provide correct temporary path, such as `/tmp/k3bVideoDvdfINBwV` to genisoimage, please review my patch, and give me some suggestion, thanks a lot!


Regards,
Leslie Zhai
