playing dvds with mplayer/vlc

Message

Netfeed · Post by **Netfeed** » Wed Jul 26, 2006 11:18 pm

hello

im trying to get my dvd player working

mplayer is emerge with what is needed(i think, cant find anything for libdvdcss2) and ive tried:

mplayer dvd://
mplayer /mnt/cdrom (mountpoint)
mplayer /dev/dvd
mplayer /dev/hdc

neither works

got one movie working with:

vlc /mnt/cdrom

but i cant recreate this now after i tried another dvd, im getting this error message:

Code: Select all

libdvdread: Attempting to use device /dev/hdc mounted on /mnt/cdrom for CSS authentication
libdvdread: Could not open /dev/hdc with libdvdcss.
libdvdread: Can't open /dev/hdc for reading
libdvdread: Device /dev/hdc inaccessible, CSS authentication not available.
libdvdnav: Can't read name block. Probably not a DVD-ROM device.
libdvdnav: Unable to find map file '/home/netfeed/.dvdnav/.map'
libdvdnav: DVD disk reports itself with Region mask 0x00f50000. Regions: 2 4
[00000223] main playlist: nothing to play
[00000223] main playlist: stopping playback

so im strating to wonder if there is something that i have missed with either my mount(mount /dev/dvd /mnt/cdrom) or there is something else that is wrong(kernel, missing some driver, wrong useflags or something simillar)

anyone that got an idea of what i can do to solve this?

When you emerged mplayer and vlc, did you have both the dvd and css USE flags enabled? If not, enable them and re-emerge them (mplayer and vlc that is).

To enable them, just edit /etc/make.conf and add them (dvd and css that is).

First, do you have libdvdcss emerged? genlop libdvdcss That's what takes care of decryption.

Was the dvd that worked in vlc encrypted?

mplayer dvd:// works for me.

mplayer /dev/dvd or mplayer /dev/hdd (my dvd location) don't work.

Code: Select all

K8II ~ # emerge -vp mplayer

These are the packages that would be merged, in order:

Don't see any css flag. May have been deprecated. equery uses mplayer also doesn't show a css flag. I'd check for the libdvdcss package.

Edit: I prefer xine-ui for just watching dvds, it does menus correctly. mplayer is way cool for playing just about any other format though.

Telling mplayer wich device to use should be something like this:

Code: Select all

mplayer dvd://1 -dvd-device /dev/hdc

Edit:
The USE flag you should use for mplayer to have libdvdcss support is "dvdread" wich will install libdvdread wich will install libdvdcss

thanks for the answears

dvd and dvdread use flags is enabled

and i dont know if the dvd was encrypted or not, couldnt play the dvd the second time

mplayer dvd://1 -dvd-device /mnt/cdrom

gives this output:

MPlayer interrupted by signal 2 in module: demux_open

last line is me ctrl+c it after looking at DVD successfully opened for 3 min

same thing with vlc didnt even give me a vlc ui to look at, but i had to kill vlc to umount the dvd

i could use xine for it but i want it to work with mplayer/vlc as it says it is possible in the man-page/help

EDIT:

ive tried xine-ui now and im getting this:

In xine did you link your cdrom to /dev/dvd? Such as: ln -s /dev/hdx /dev/dvd

hmm, no where should i do this? in the dvd device field it says /dev/dvd

You shouldn't do this.
If this is a video dvd (the one you watch on a dvd player) you don't have to mount it, just put it in the drive and open it from the device.
If this is a data dvd, you should mount it, 'cd' to the mountpoint and play the files inside with 'mplayer some_video.avi' or something, and not with 'mplayer dvd://1'.

I'm not quite sure about what's happening to libdvdread though. It says it can't open the device and then it says it opened it successfully.
Are you sure this dvd is good? have you played it somewhere else?

Netfeed wrote:hmm, no where should i do this? in the dvd device field it says /dev/dvd

Thing is /dev/dvd is not really the device, it's a link to the real device. I think Bill Thompson means that maybe xine can't open /dev/dvd because it is linking to the wrong device.
You can check with a

Code: Select all

ls -l /dev/dvd

Netfeed · Post by **Netfeed** » Fri Jul 28, 2006 1:12 pm

a ls -l /dev/dvd says that says that its pointed to hdc, but i think i know what it can be, not sure thougth. got this in /etc/fstab:

Code: Select all

/dev/cdroms/cdrom0      /mnt/cdrom      iso9660         noauto,ro       0 0

could it be that it must be something like:

Code: Select all

/dev/dvd      /mnt/dvd      iso9660         noauto,ro       0 0

to work properly?

EDIT:

nope, there was no change in the behavior there

cwest · Post by **cwest** » Fri Jul 28, 2006 2:53 pm

Nothing about fstab, as /etc/fstab is merely for mounting. You don't need to mount the DVD, it reads it directly. Methinks libdvdcss needs write permissions to the device, but not sure.

1:
Is it a permission error? (AKA test it quick n' dirty - sudo vlc dvd://)

2:
Is it a symbolic link gone bad? (IE ls -l /dev/dvd should output the /dev/hd? where the DVD's really located)

result! yes, i got a result

but eh, it wasnt really what i expected, it started to spark(rigth word i hope) and then i got the picture in the terminal instead of in its own window

guess that its a permission error

EDIT:

yeah

chmod +r /dev/hdc did the works, but i lost my sound

Be sure that you've added yourself to the "cdrom" and "cdrw" groups (comma delimited in /etc/group), like this:

cdrom12:foobar,netfeed
cdrw13:foobar,netfeed

(Or use the command line tools if you want, or even the GUI tools if you like that the best)

Netfeed · Post by **Netfeed** » Fri Jul 28, 2006 4:57 pm

well, i cant get sound in mp3:s, movies or dvd:s

tried alsamixer and if i turn on PCM i can get some sound in avi-files and mp3:s but if i then tries to turn on a dvd there is just a noise that sounds, nothing else
i dont know if PCM was on or off before, but it gives me atleast some audio on everything except dvd:s

EDIT:

seems like the noise was only on that movie, i have to test this more before i know for sure, but i guess that this could be counted as solved

Well, mplayer is telling you there's no audio stream.
You could try

Code: Select all

mplayer dvd://1 -identify

then take a look at the audio stream mplayer lists.
If there is any, you can try to play them with

Code: Select all

mplayer dvd://1 -aid <stream number>

Ah, excellent. I was having the same trouble, but decided to add my users into the cdrom group, rather than give global read access to hda
