Ubuntu UDF patch

[addisor]

iv'e just tried installing a UDF 2.5 patch to my gutsy install so that I can play Blu-ray DVD's with DumpHD and now appear to have made a mess of my /etc/fstab file.

I did this
wget http://www.strapp.co.uk/files/udf-$( uname -r ).ko
sudo mv udf-$( uname -r ).ko /lib/modules/$( uname -r )/kernel/fs/udf/udf.ko and followed the rest of the text,

dmesg grep | UDF reveals nothing, I fiddle with my /etc/fstab and now have this

/dev/hdc /media/cdrom0 auto 0 0
/dev/hdc /media/cdrom0 udf,iso9660 user,noauto,exec 0 0
/dev/scd0 /media/cdrom0 iso9660,udf user,noauto 0 0

How do I get the UDF patch to work? when i try and mount dvd I get told i dont have the right privilege

[nm]

Did you run sudo depmod -a and actually load the module: sudo modprobe udf?

What guide did you follow?

[addisor]

Just try this from www.strapp.co.uk

Your signature says that you're using a 64-bit kernel. 32-bit modules won't work in it.

Thanks, it suddenly dawned on me, while your there, When I did demod -a, could it have messed my sound up as alsa SPDIF no longer works and I can't get it back!!!

Going to give up on blu-ray for a while.

I'd say try running a linux distro that doesn't try to keep you using legacy packages

but I don't blame you on giving up on blu-ray
now if only the studios would follow suit...

It shouldn't do that by itself (depmod just updates the module dependency lists, which is standard procedure when installing new modules). I'd say the SPDIF problem was caused by something else--especially if analog sound output still works.

yea it is quire bizzare, DVD's with DTS work over spdif but XMMS and avi files from file have no sound over spdif, what do you think?

What would a better linux distro be then?

Then you'll just need to select the correct output (IEC958) in the settings of those programs, or tune your .asoundrc to use dmix and redirect output to S/PDIF. For example, I have the following settings in ~/.asoundrc for my Envy24HT (which has digital ouput as hw:0,1 device):

pcm.envyspdifdmix {
  type dmix
  ipc_key 1024
  slave {
    pcm "hw:0,1"
    format S32_LE
    period_time 0
    buffer_time 0
    period_size 2048
    buffer_size 32768
    rate 48000
  }
}

pcm.dsp0 {
  type plug
  slave.pcm envyspdifdmix
}

pcm.!default {
  type plug
  slave.pcm envyspdifdmix
}

pcm.!iec958 {
  type plug
  slave {
    pcm "hw:0,1"
    format S32_LE
  }
}

Note that this probably won't work directly on your hardware. I may be able to give more appropriate settings if you show the output of aplay -l, which lists available playback devices.

What would a better linux distro be then?

Each user has their preferences, and I think Ubuntu is as good base for Blu-ray/HD-DVD playback as any distribution. All you need to do is compile your own kernel with whatever patches needed.

rob@rob-desktop:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC883 Analog [ALC883 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: ALC883 Digital [ALC883 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
rob@rob-desktop:~$

Any help would be great?

[nm]

Ok, ALC883 should duplicate PCM output to S/PDIF automatically, but it can be disabled in the ALSA mixer (for ALSA > 1.0.14rc3). Perhaps that's what has happened? Try to tweak the output settings with alsamixer.

You may also need to specify the right model when loading the module, if it is not detected correctly. I doubt this is the case since aplay -l lists digital output.

I've been trying the UDF 2.5 patch for Gutsy for a while, and had almost given up. I got it to work today.

Please see this thread

There's is a precompiled udf.ko file. You only need to replace your udf.ko with this one (Make a backup first, just incase).

Worked for me. I can finally mount blu-ray discs.

[addisor]

Do you know if this is 64bit or 32bit patch? I need 64bit.

[bmnot]

That's for 32-bit. I don't know if it'll work for 64-bit, but you could try it after you make a backup of udf.ko

He already tried a 32-bit version and it will not work, as can be seen in the first few posts of this thread.

The zen kernel is prepatched for UDF and a bunch of other great features.

http://www.mattparnell.com/zen-kernel.html

[addisor]

Just tired the latest 32bit patch on 7.10 64 and again no success!! never mind I persevere. Not sure what to actually do with the ZEN suggestion? advice?

[evade]

it's simple, just install the packages and reboot.

[addisor]

Took the ZEN plunge!!! made a bit of progress,

rob@rob-desktop:~$ dmesg | grep UDF
[ 69.589510] UDF-fs: minUDFReadRev=250 (max is 201)
[ 97.888006] UDF-fs: minUDFReadRev=250 (max is 201)

That never used to happen and also modprobe doesn't error.

Except when I put a blu-ray in this still happens

Invalid mount option when attempting to mount the volume '32005129_LAYER_CAKE'.

Were nearly there, come on guys???

[nm]

What do you have in /etc/fstab?
