Notes:<BR>
|
|
|
|
|
- Do NOT mount VCD disks and play DAT files directly! It may work under windows
|
|
|
|
|
but won't work under linux. You have to play them directly, with the -vcd
|
|
|
|
|
option!<BR>
|
|
|
|
|
- VCD disks usually have 2 tracks: a data track (containing autostart windows
|
|
|
|
|
playback program, karaoke data etc) and a mode-2 track (the movie), so try
|
|
|
|
|
-vcd 2 first!<BR>
|
|
|
|
|
- the default VCD device is /dev/cdrom. if your device differs, then you have
|
|
|
|
|
to make a symlink, or specify it in command line!
|
|
|
|
|
</P>
|
|
|
|
|
|
|
|
|
|
<P>From Linux documentation:</P>
|
|
|
|
|
|
|
|
|
|
<P>Some CDROM drives are capable of changing their head-speed. There are several
|
|
|
|
|
reasons for changing the speed of a CDROM drive. Badly pressed CDROMs may
|
|
|
|
|
benefit from less-than-maximum head rate. Modern CDROM drives can obtain very
|
|
|
|
|
high head rates (up to 24-times is common). It has been reported that these
|
|
|
|
|
drives can make reading errors at these high speeds, reducing the speed can
|
|
|
|
|
prevent data loss in these circumstances. Finally, some of these drives can
|
|
|
|
|
make an annoyingly loud noise, which a lower speed may reduce.</P>
|
|
|
|
|
|
|
|
|
|
<P>The recommended way to do it is with a program called 'setcd' . It's kinda
|
|
|
|
|
old, but won't be too hard to find on the Net. (UPDATE : new hdparm
|
|
|
|
|
has an option for this !)
|
|
|
|
|
Use it with :</P>
|
|
|
|
|
|
|
|
|
|
<P> <CODE>setcd -x [speed] [cdrom device]</CODE></P>
|
|
|
|
|
|
|
|
|
|
<P>Also you can try:</P>
|
|
|
|
|
|
|
|
|
|
<P> <CODE>echo current_speed:4 >/proc/ide/[cdrom device]/settings</CODE></P>
|
|
|
|
|
|
|
|
|
|
<P>but you'll need root privileges. I use following command too:</P>
|
|
|
|
|
|
|
|
|
|
<P> <CODE>echo file_readahead:2000000 >/proc/ide/[cdrom device]/settings</CODE></P>
|
|
|
|
|
|
|
|
|
|
<P>for 2MB prefetched reading from the file (it's useful for scratched CDROMs).
|
|
|
|
|
It's recommended that you tuneup your CDROM drive also with hdparm:</P>
|
|
|
|
|
|
|
|
|
|
<P> <CODE>hdparm -d1 -a8 -u1 (cdrom device)</CODE></P>
|
|
|
|
|
|
|
|
|
|
<P>to enable using DMA access, readahead, and IRQ unmasking.
|
|
|
|
|
(if you don't understand these, *read the hdparm manpage*)</P>
|
|
|
|
|
|
|
|
|
|
<P>Please refer to "<CODE>/proc/ide/[cdrom device]/settings</CODE>" for fine-tuning your
|
|
|
|
|
CDROM.</P>

<P><B>MPlayer</B> uses <CODE>libdvdread</CODE> and <CODE>libdvdcss</CODE> for

|
<CODE>libmpdvdkit/</CODE> subdirectory in the <B>MPlayer</B> tree, you
|
|
|
|
|
don't have to install them separately. We opt for this solution because
|
|
|
|
|
we had to fix a libdvdread bug, and apply a patch which adds
