    Anyone got a BluRay drive in your miggy?
    Can you play a BluRay with MPlayer?
    The MPlayer docs say it will do BluRay.

    First of all, MorphOS won't mount BluRay discs... and I kind of doubt your CPU would be able to decode them fast enough for any acceptable playback.

    I have a hard time believing MOS won't mount a bluray drive when it can mount a 128gb sfs partition.

    maybe because the bluray filesystem isn't supported by MorphOS ?

    the HDCP protection could be also an issue no ?
    I can't think of any hardware supported by MorphOS, not even in the future (G5 machines) that is hdcp compliant. Unless it can be bypassed ?

    Why would you need to be HDCP compliant to play BluRay movies? :)

    That reference would seem to indicate we might be able to do this with a littel work.

    As long as by "little" you mean a G5 port, UDF filesystem and updated MPlayer port.

    (well... who knows, perhaps the strongest G4s could handle that too...)

    just to avoid reading boring hack or workarounds tutorials : )

    thanks for the link though, that's interesting.

    I've got a 1.8 Ghz.G4. The Mplayer port is do-able, but the UDF file system seems a bit daunting.
    MakeMKV and the Matroska Multimedia Container look interesting..
    Could Mplayer read UDF files on its own w/o OS support?

    1080P MKV files play on Mplayer (albiet a little slow). Whern the new video drivers come out playback should be adequate.
    So, all we need is something like MakeMKV that can convert Blurays to a playable format.

    I doubt that the new video drivers are going to change that. On MorphOS it's the CPU that's decoding A/V and syncing them. To be able to properly view 1080p content on a G4 based system we'd need drivers that use the GPU to decode the video stream.

    I don't think MakeMKV would do us any good unless we had the UDF filesystem first.
    Who is the filesystem guy?
    We need another port!

    I would just like to be able to read UDF.
    Don't care if movies work.
    I'd like to read data that has been backed up to a bluray using my PC.
    Makes it easier to transfer large files and store them long term.

    Then we reduce playback quality to 720P. We know that works.. What we need now is a way not read Bluray and convert files to an easily displayed format. That's why I like the MKV format.

    Do we need a bounty on UDF or is the filesystem guy willing to do it?

    I'd second that. If bluray UDF files can be accessed, then they can be decrypted and converted to other formats.

    How about it guys?

    @Jim

    New video drivers won't help with video playback really. I guess smooth 1080p playback (with a high bitrate) might not be possible without decoding on more than 1 cpu at once (at least that's often the case on my Quad OSX machine, then again OSX obviously wastes a lot more CPU power than MorphOS does).

    UDF is nowhere on our priorities list atm.

    What has this got to do with MKV ? The Ubuntu wiki only mentions MakeMKV because it has a DRM key for AACS that has not been revoked yet.

    You make it sound as though it is possible to playback 1080P content at 720P without a lot of processor power (?) -> You will have to decode at 1080 and then scale down, so that's even more processing!

    I agree it would be nice to have the UDF filesystem and AACS decryption so that data on Blu Ray could be accessed. But for playback you need a faster machine or you need to decode, scale and encode to make an offline copy. I don't think there will be a fast enough decoder on current hardware without GPU acceleration and that is probably not possible until a full OpenGL implementation is available.

    In the mean time, I believe it would be legal to download a torrent of the BluRay movie you have bought and it will already be nicely scaled. Or buy the DVD ;)

    Do you say that a full OpenGL implementation could somehow enable the opportunity to use the GPU for video decoding? Or did I misunderstand you here?

    Alright, everybody has "HD" and "1080p" in his mought nowadays... But is there really that much high definition content to watch? On minuscle hobby computers like ours? If you really must have HD playback, there are cheap devices dedicated to it.

    I'm not saying it's not interesting, but techcnically impossible in the end...

    I think that the amount of HD content out there is barely dependent on the kind of computers we use ;-) To get an idea, go to Youtube, search for a random term and compare the total number of results you get with the number of results you get after applying the HD filter in the search options.

    > techcnically impossible in the end...

    HD at 720p resolution is possible on the faster G4 based systems we have today. HD at 1080p resolution is said to be possible on the even faster G5 based systems we'll hopefully get some day.

    Not tomorrow, guys. It's possible today. First we have to be able to read UDF. Then we need the key for decryption (that's why I mentionrd MakeMKV). Then, we'd have to do some conversion 1080p to 7290p). Mone of this has to happen in real time.
    Finally, once we have the 720p files, we have enough CPU/GPU power to play it back.
    How many LCD TVs are limited to 720p?
    We could do this and we could do it now.

    The G5 is only necessary if you insist on playback direct from the disk.

    When I talk about 1080p playback I refer to actually playing back 1080p content as is, not 1080p content converted to 720p content. That would be 720p playback. Going by what you say we could even play 1080p content on an Efika 5200B, namely by converting it to 360p beforehand ;-)

    > How many LCD TVs are limited to 720p?

    I think that computer screens with resolutions of 1920x1080 or more are very common these days. Unfortunately, I still have 1680x1050 ;-)
