@ -102,6 +102,18 @@ By default the filter feature is disabled if effective user id and real
user id differ. This ban can be lifted by
--enable-external-filters-setuid
In some situations Linux may deliver a better write performance to drives if
the track input is read with O_DIRECT (see man 2 open). The included libburn
and the cdrecord emulation of xorriso can be told to use this peculiar read
mode by:
--enable-track-src-odirect
But often libburn will yield even better performance in such a situation if
64 KB are transmitted in each write operation rather than 32 KB.
64k can be made default at configure time by:
--enable-dvd-obs-64k
This may be combined with above --enable-track-src-odirect .
If you want xorriso to report a "Build timestamp" with its option -version:
make buildstamped
