[MPlayer-users] dvd reader and dvd burner switch

[Karl Ewald]

Hi Nicolas,

since you don't give any information about your system, I can only respond
in general terms.

I assume that mplayer accesses the IDE devices and during some probes,
resets, or whatever the SCSI emulator shuffles the devices around.
I recommend that you specify the SCSI emulated device as the DVD drive that
mplayer should use, e.g. -dvd-device /dev/scd0
By only accessing the emulated SCSI device, the emulator shouldn't get the
carpet pulled under its feet.

If you have further problems, make sure you give the information listed in
bugreports.html, and please also check your system log for messages from the
scsi emulator (do a tail -f /var/log/messages or similar while starting
mplayer so you can report when during the mplayer run the change happens).
Check the relevant manpages for hints. You may also be able to nail down the
assignment between IDE and SCSI devices by configuring the scsi emulator.

Hope this helps,

Karl

Hello,

at boot time, I have:

dvd burner : hda mapped on scd0
dvd reader : hdc mapped on scd1

after this little scirpt :

#!/bin/bash

piste='14'
bitrate='1200'
crop='720:432:0:72'
sid='0'

nice -19 mencoder dvd://$piste -ovc lavc\
     -lavcopts  vcodec=mpeg4:vbitrate=$bitrate:vhq:vqmin=2:vlelim=-4
     :vcelim=9:lumi_mask=0.05:dark_mask=0.01:gray:autoaspect:vpass=1\
     -oac copy -o /dev/null -vf crop=$crop

nice -19 mencoder dvd://$piste -ovc lavc\
     -lavcopts vcodec=mpeg4:vbitrate=$bitrate:vhq:vqmin=2:vlelim=-4
	:vcelim=9:lumi_mask=0.05:dark_mask=0.01:gray:autoaspect:vpass=2\
     -vobsubout sous-titres \
     -vobsuboutindex 1 \
     -sid $sid \
     -oac copy -o film.avi -vf crop=$crop

I have :

dvd burner : hda mapped on scd1 instead of scd0
dvd reader : hdc mapped on scd0 instead of scd1

They switch. Do you have any idea why, and how prevent that.

Thanks. Nicolas.
