Playing DVD (or Blu-Ray)

[mikerr]

So now we have MPEG2 (DVD) and VC1/MPEG4 (blu-ray) on the GPU,
has anyone made any progress towards DVD or bluray disk playback ?

I know dvdnav isn't in Raspi XBMC:
http://forum.xbmc.org/showthread.php?tid=140451

and XBMC DVD code is done in software anyway.

A project to start, or has anyone got anywhere yet?

omxplayer can play individual .vob files (in chunks of 1GB)

[jamesh]

Has BluRay been cracked to work on Linux (not just Raspi) yet?

[mikerr]

Yes, but not quite as comprehensively as DVD

makemkv or dumphd can stream direct from the disk into vlc or mplayer.

[mikerr]

Decided to move forward:

Code: Select all

wget http://www.videolan.org/pub/libdvdcss/1.2.12/libdvdcss-1.2.12.tar.bz2
bzip2 libdvdcss-1.2.12.tar.bz2
tar -xvf libdvdcss-1.2.12.tar

cd libdvdcss-1.2.12
./configure
make
make install

(quick compile, only took a minute)

Copy over the libs

Code: Select all

sudo cp /usr/local/lib/libdvdcss* /lib

Code: Select all

mplayer dvd://1 

Success !

of a sort.. it plays but mplayer is not GPU accelerated, so 8 fps

You can dump the whole 4GB with

Code: Select all

mplayer dvd://1 -dumpstream -dumpfile dvd.mpg

OMXplayer is GPU accelerated mpeg2 (if you have a licence) but it won't work directly with that file (or stream...)

[mikerr]

OMXplayer DOES work fine on the resulting file - I hadn't got the licence on that SD card

- fixed and all working full frame rate now

Next up is to get it working without needing to store the file on disk first (streaming from disk) !

[jamesh]

Nice work so far!

Is that a "real" external ODD ?

[mikerr]

Is that a "real" external ODD ?

Yep a physical DVD drive connected via USB.
Real live encrypted DVD disk too

Got it streaming direct from DVD disk working now

Using a named pipe:

Code: Select all

mkfifo  /tmp/dvdpipe
mplayer dvd://1 -dumpstream -dumpfile /tmp/dvdpipe &
omxplayer -r /tmp/dvdpipe 

Though I think the exact commandlines could do with work, as I was bringing them into and out of background (ctrl-z ...bg...fg)

[ghans]

Nice !

omxplayer can play individual .vob files (in chunks of 1GB)

I've got as far as that, but only for unencrypted stuff I recorded myself.

You can also use Openelec to do the same thing, but it doesn't seem to come out full screen (omxplayer needs the -r to make it full screen - I think you told me that last week didn't you Mike? )

Now I've read the rest of the thread I see you've already got further than that. Well done.

[mikerr]

Ok, I've done some more testing, and it seems mplayer needed a bit more silencing to run in the background,
so I've included a better sequence of commands below.


To recap - first get the libdvdcss compiled on your Pi:

Code: Select all

wget http://www.videolan.org/pub/libdvdcss/1.2.12/libdvdcss-1.2.12.tar.bz2
bzip2 libdvdcss-1.2.12.tar.bz2
tar -xvf libdvdcss-1.2.12.tar

cd libdvdcss-1.2.12
./configure
make
make install

(quick compile, only took a minute)

Copy over the libs

Code: Select all

sudo cp /usr/local/lib/libdvdcss* /lib

That's the decrypting library installed, now here's how to play DVD direct from the DVD drive:

Code: Select all

mkfifo  /tmp/dvdpipe
mplayer dvd://1 -dumpstream -dumpfile /tmp/dvdpipe 1>/dev/null 2>/dev/null </dev/null &
omxplayer -r /tmp/dvdpipe 

Normal OMXplayer keys to control
http://www.raspberrypi.org/phpBB3/viewt ... 63&t=13328

Note: this is streaming direct from the DVD disk, no SD space is required.

Enjoy !

[Now moving to getting bluray to work ...]

Hi Mike.

tried your first set of instructions, but errored out on the make install. Only worked with sudo.

Then tried to install mplayer and that gave lots of errors. It installed, but didn't work.
I'll try it on a clean install of the latest Raspbian tomorrow. Perhaps it's better to have installed mplayer first?

[alexeames]

Couldn't wait until tomorrow. Tried it on a clean install.
Everything installed beautifully.

But now the darned OS can't see my DVD drive when it all automounted perfectly before. (although it spotted it on boot - I saw it) GRRRRRRRRRRRRRRR. Busy day tomorrow as well.

[alexeames]

I got your streaming technique working on an unencrypted dvd this morning Mike. It looks like the latest Raspbian with updates/upgrades sees my USB DVD drive differently. It doesn't appear in df -h as a mounted drive, or in lsusb. I've also got occasional keyboard repeaaaaaaats/dropots again - even on the Pi with shorted polyfuses.

I'll have another go with (maybe different) encrypted ones this evening. I've only tried BBC ones so far. Maybe a different one will work? Really want to get this working - not because I need it, but because it's annoying me that it ought to work.

[Update]
Well blow me down. I just tried a different commercial disk and it worked a treat. The only other thing I did differently was send the mplayer and omxplayer commands by ssh because I couldn't be bothered to type them out with a sticky keyboard

Mike, you're a genius

[2nd Update]
Just retried one of my BBC DVDs (The Blue Planet) sending the mplayer and omxplayer commands via ssh, and guess what? That works too. Goodness knows why, but who cares? IT WORKS

[mikerr]

Great, glad to hear you got it working - and it verifies my instructions are correct

[alexeames]

They're bang on except for the sudo and the bunzip.

I notice the output is a bit "interlacey", but I don't care, that could just be the upscaling of 720x576 for HD TV.

I do have issues with omxplayer controls not working very well and crashing on quit, but that's not a DVD issue. Just glad to get it working on encrypted disks at all.

[mikerr]

Yes, omxplayer can pause (with p or space) fine, but seek controls are not too good,
due to the fact that mplayer is just blindly dumping the movie sequentially in the background.

[alexeames]

I've blogged the full sequence of how I got this working based on your instructions Mike, with a link back to this thread, so people can stay abreast of developments.

http://raspi.tv/2012/watch-encrypted-dv ... -omxplayer

Hopefully the instructions are complete and reasonably "friendly".

Still got no idea why it works via ssh but not right there on the console

[mikerr]

Ahem... I now have it working in XBMC GUI

Yes, I can play commercial DVDs on XBMC entirely with my MCE remote, no SSH or keyboard needed !

Hark at Mr smug. Great work Mike!

Which version of XBMC? Have you built it into Raspbian or used one of the distros?

[mikerr]

Nope, I didn't recompile XMBC, just a nasty hack:

compile libdvdcss
install mplayer
mkdir /dvd
run infinte script on startup (call it from /etc/rc.local)

Code: Select all

mkfifo /dvd/dvd.mpg
while :
do
        mplayer dvd://1 -dumpstream -dumpfile /dvd/dvd.mpg 1>null 2>null
        sleep 5
done

Add /dvd as a video folder in XBMC

When you want to play a dvd, play the dvd.mpg file (which is really a named pipe)


The script running in the background will take care of dvd changes.

[alexeames]

It's not a nasty hack, it's tricking the bleedin' thing into doing what you want it to.

Where did you learn about this stuff Mike?

[mikerr]

It's very similar to TiVo hacking that I used to do a few years back
- I've actually had a few PMs from people recognizing my username on here - hello to all the TiVo S1'ers !

[mikerr]

I started from scratch with a fresh RaspBMC image to check steps,
and made a new thread with instructions on how to do it in RaspBMC:
http://www.raspberrypi.org/phpBB3/viewt ... 35&t=17877

[Salamander]

Wonder if this technique could also be used (in XBMC GUI) to play streams using codecs not supported by OMXplayer/RPi, like flash (or MPEG2 without a license). That would be a rocket jump from current situation and would allow anybody to play any media. Then one could opt for a license when hardware acceleration is really needed.
