    As kind of a follow up to an older thread of mine, I've recently discovered that, indeed, I can watch DVD with my Pegasos I G3.
    The difference is that now, I've found and tried a couple of commercial but unencrypted DVDs. I simply tell MPlayer to open a "VOD" file, and it works. How do I know that the DVD is not encrypted? Easy: I can actually copy it as a file. Encrypted ones can't be copied, a generic filesystem error is raised when attempted ("Volume x has a read/write error").
    My question is: The lack of performance came from the extra task of decrypting the file?

    Not an answer, but did you try latest MPlayer already? It has cache2 buffering implemented, which will speed up DVD playback considerably.

    Nice one! You know, this MorphOS thingie has so much separated developers that it's difficult to have up to date software. I've just downloaded it, and will try it at home. Until now, I was using "1.0 pre 4" version, if I remember correctly.

    jcmarcos,

    1.0pre4 is now quite outdated.

    Since mid-2005, AFAIK, I've been the only mplayer morphos maintainer (which consisted mainly in synchronizing to common mplayer tree and improving a bit morphos backend): there were 1.0pre7, pre8, 1.0rc1 (pre)releases and now some current svn snapshot with cache enabled, which allows to watch netstreams and dvd in better conditions.

    But it's true that latest svn version didn't make it to morphzone news items tho even though it was submitted in many other news sites. Do you know many other versions of mplayer for morphos, BTW?

    We are all grateful for your work in maintaining both Mplayer and Mame for us. :-)

    You are a hero. So what is the latest MOS version and where can we get it please? Thank you

    Personally, i only know yours.

    This is a bit off-topic but i was wondering if you could add audio support for 3gp files. They are still fairly popular and only the video stream is played with your port of MPlayer.

    amr support needs additional sources, that's why it's disabled, I'll try to add it.

    However, if you can point me to some 3gp sample with amr audio codec, that would be handy.

    That would be great. :-)

    Every 3gp file i have tried is soundless on mplayer for MOS (and i have tried many files) and this means that: a)All 3gp files are using the same audio codec. b)All 3gp audio codecs are not supported by mplayer for MOS.
    You can find many 3gp's in these links:

    Would it be possible to add amr (and aac and 3gp) to Mencoder, too?

    any codec added to mplayer is also added to mencoder anyway. But it's boring to compile shitloads of external libs. :)

    Could answer this common question, I'll try to put it in a simple way...

    When you play files from disc (be it .vob files or whatever), they're accessed via filesystem.

    When playing dvd with -dvd (or however it was on newer mplayer versions) mplayer accesses the video without filesystem in between. This is the difference and the bit that was earlier too slow due to lack of caching.

    Aha. I have to try again with the "dvd" option. By the way, is there any documentation about the MorphOS specific options, aside from "readme.morphos" file? I've started to read the original MPlayer docs, but this program does so many things, that it's an exhausting read! Particularly, I'm afraid of doing things wrong, because the "help" option in MorphOS version does not show all the information that this option shows in Win32 version.

    Another question: What's that "No ICDT acceleration found"? I don't remember the message exactly. Does MPlayer actually look for available hardware acceleration aids?

    There aren't other specific morphos options, except those listed in readme.morphos. And what are the additional options you see in win32 port? They are probably not that useful. MorphOS port more or less displays the same help as unix port.
