Question Non-interlaced DVD playback? No encryption-probs? Is this possible?


Hi,

just a quick question to all the linux specialists out there.
In the last 2 weeks I've checked out several distros
(Mandrake 9, RH9, FedoraCore1 and now VectorLinux, which is really nice)
and I'm really willing to give Winpoop up, but there are some things that annoy me.

For example: Interlaced video with ALL videoplayers and general probs with encrypted DVD's

First, the interlace problem:
I checked out Ogle, Xine, Mplayer and Totem - none of those players
managed to give me a decent playback and f.e. Ogle has a statement on this prob on their site:
*************************************************
33. There are strange horizontal lines in the image. Why?

Sample pic: click here

This is not an error. The image is coded interlaced and is usually used
when transferring video to dvd. You can make it look nicer by filtering
(deinterlacing) it. This is not currently implemented in Ogle.

*************************************************

Maybe I'm just to spoiled from winpoop dvd playback with f.e. WinDVD,
but it's no fun watching a DVD like this. Hurts my eyes...
(PS: For any of those "GET A DVD PLAYER!" shouters: I've got a nice 21"
screen and would like to be able to watch DVD's on that one. )

Second problem: Encryption
My old "Contact" DVD played without a problem on all players, but as I
popped in my new bought "Lord of the Rings - The Two Towers,
Special Extended Edition" in there: Nope! Not with me!
Ogle managed to get the decryption keys from the DVD, MPlayer and Xine
just gave me CRC errors, unwatchable colorfull pixel-poop or frozen applications.
A good friend of mine has the same problem with many cd's , like f.e.
the new Indiana Jones Trilogy package.

I really like Linux - it's fun working with it, but I would like to be
able to watch DVD's directly under it. Not so much fun to close everything
up and boot into Windows, just to watch a new DVD.

Maybe someone can tell me if there's a way to fix this. If not , maybe
someone has heard rumors, when this could be solved?

Cheers

Have you compiled MPlayer from source? If not then try recompiling from source as I have never had a problem accessing a disk with it (including LOTR 2 Towers). I am also fairly confident that MPlayer has a de-interlace option somewhere (check the man pages for the full list). About the only thing MPlayer doesn't do is menus, and quite frankly I've managed to do without for years now.

I compiled both version .92 and .10pre2 (I always try to compile from source)
but it didn't change anything. If I try to open a .VOB file from LOTR2 , mplayer only gives me
a bunch of colorfull pixels and sound. CRC errors show up all over the place, when
i start the prog via console. Libdvdcss (or something like that, don't know how it was
spelled exactly *G*) is installed, working with Ogle, but not with Mplayer.

IF Mplayer plays a .VOB the movie is interlaced... and I haven't found
any "deinterlace" mode for it :-/ A good friend of mine uses Linux for
some time now and he also hasn't figured it out yet *sighs*

I have mplayer-0.91-2, built from SRPM with various codecs enabled, and I have no problems playing the standard LOTR:TTT disc using mplayer or Ogle. Try one of the prepackaged SRPMS; you may be missing a non-obvious codec or setting which is required to play interlaced DVDs.

Is there something like prepackaged SRPMS for Slackware / Vector Linux?
I haven't stumbled over something like that yet

If you see garbled video but hear the sound just fine, then try deleting your player's configuration directory (~/.xine for xine, for example) and playing the movie again. That will get rid of the cached CSS keys and force the player to get new ones. It may do it properly this time.

Both MPlayer and Xine can deinterlace. If you're using Xine, the hotkey to toggle deinterlacing is "i". Its default deinterlacing mode simply throws one field (and half the video quality) away, but you can find other deinterlacing modes in its setup dialogue boxes.

If you're using the 1.0pre releases of MPlayer, then you deinterlace by passing it a "-vf" (video filter) option on the command line. Type
"mplayer -vf help" for a list, and then use the deinterlacing filter of your choice.
