"mplayer -vo xvidix" problems with sudo
Hi
The only way I can get mplayer to work as well as or better than its Windows
counterpart on my hardware is by using "-vo xvidix" option that requires
superuser privileges, so I added
oleg ALL = (root) NOPASSWD: /usr/local/bin/mplayer *
to /etc/sudoers. Now "sudo mplayer -vo xvidix file_name" starts (no
permission problems), but fails with these errors:
------------ errors when running with sudo----------------
No vidix driver name provided, probing available ones!
vosub_vidix: Couldn't find working VIDIX driver
Error opening/initializing the selected video_out (-vo) device!
-------------------end----------------------------
Surprisingly, however, after doing "su" instead of using sudo, everything
works fine (output below). Why the different behaviour with sudo compared to
su?
Thanks
Oleg
