OpenELEC DVD Help

[JeremyF]

I would like to play DVDs on my Raspberry Pi. I am aware that MPEG2 is not accelerated by the GPU.

1)I have a USB DVD drive, externally powered. It is recognized by OpenELEC and the "Play Disc" option appears
2)The DVD is a standard, commercially bought, encrypted DVD
3)Upon selecting "Play Disc", one of three things happen:
a)The disc shows up, but as a mounted folder (i.e. it shows me the VIDEO_TS folder, which is not what I want.)
b)The Now Playing window shows up for a second, then crashes
c)Nothing happens at all after clicking (This usually occurs after a or b happens, then I go for a second attempt)

Any help would be appreciated.

(I got the image for OpenELEC here: http://kvarley.co.uk/RaspberryPi/OpenELEC/ )

Anyone know?

You cannot play DVD's because the VOB files on the DVD are MPEG2 and not supported at this time.

But shouldn't I be able to play them unaccelerated?

I don't think that omxplayer can handle them.
You could try a different player.
A way to experiment would be to put the "official" Debian release on an SD card and experiment with that (Openelec is quite locked down if you are simply using prebuilt image).
From the Debian build you could try ..
sudo apt-get install mplayer ffmpeg
And then experiment with different command lines.
With current software you might get around 10 fps

If you search this forum for references to mpeg2 or mpeg-2 you should find that an interesting experiment is in progress by a couple of people to try to break out parts of the mpeg2 and use some of the accelerated parts of the graphics software to handle it ... and it looks like they might get things to an acceptable level.
Plus - there appears to be a good chance that RPi Foundation is trying to make it possible for RPi to buy MPEG2 decode licence (to be associated with the serial number of device) so that omxplayer (and anything else that knows how to exploit the GPU) can get acceleration more easily.

If you say encrypted DVDs do you mean CSS ?
I suppose this adds a extra load to the CPU , but it may work with overclocking.

Alright thanks for the suggestions. I'll get back to you shortly.

[JeremyF]

OK. Here's what's going on.

Unencrypted MPEG2 DVDs - Play with no picture, but sound works fine. However, they are still mounted as folders (have to play title files individually)
Audio CDs (CDA) - Error about playback

Yet to try decoding with ffmpeg on Debian; I've been busy.

any news about your experiences concerning playing DVD on the raspberry pi?

[robwriter]

Check out the MPEG-2 threads. Out of the box the frame rate is awful, with some work people report 18fps.

So the reality is Pi can't do DVDs right now.

Actually, I haven't worked on it for a while. I can report back in a few days if you want. I'm first going to simply try playing in mplayer with ffmpeg on Debian, see how that goes.

Any news about playing DVD (Mpeg-2) on Pi? Why isn't there any codec available to play it?

[ghans]

Beacuse codecs cost money. The foundation already pays for h.264 and this also influences
the price customers (we ourselves) pay for a Pi.
Check out the MPEG-2 threads !

[danco]

I don't understand why would they buy h.264 licence if most of the pople use mpeg-2?

[ghans]

Yeah , you're not only one :

Just post there to avoid duplication - it has become the inofficial "can i haz MPEG2 " thread.

Ok tnx

Ok, so now we have mpeg2 codecs has anyone managed to actually get dvds working properly on the Raspberry Pi? Using OpenELEC and omxplayer, I can manage to play my own stuff recorded from TV, but commercial encrypted dvds (eg BBC Planet Earth series) won't play. Tried installing libdvdcss2 but I don't really know what I'm doing.

Anyone got further than that? I notice a Youtube vid witha guy that looks like he's playing a dvd on the pi was streaming his dvd onto the Pi from a squeezebox, not actually playing it with the dvd drive connected to the Pi.

So, any progress anyone?

i believe that XBMC has to be compiled with libdvdcss, to be able to play encrypted dvds. You could try to use either raspbmc or OpenELEC and build xbmc with support for it. that is if libdvdcss compiles and how well omxplayer, the default player, integrates with that...

That's the thing really - I've not done much compiling, and what I have done had fairly good instructions.

Don't waste your time, Read this

. All dvdnav support is disabled in the player and not supported.
