Thanks for the Info. :)

Status:
I'll recieve the keys to my hd media on monday (from a colleague at work, who will find them using windows).
As soon as I get them I'll report about the results of dumping/playing.

For burning bluray I got nero (I like having simple guis). So that works fine.
Data reading/writing is no problem, the main issue remains playing films.

Update:

My american HD-DVDs just arrived - too bad I'm going to be away for the weekend. :|

Hey,
I've just setup xp inside virtualbox, seems to work fine.

Now I just need to acquire a copy of AnyDVD HD and see if I can dump my Bluray.

Once dumped/decrypted I'll transcode it in Gentoo and let you know how that goes.

Success! :D

I was able to dump my first HD-DVD film using the dumphd tool in linux.
The problem with the other film I tried before was that the volume unique key (I thought I had found it using aacskeys) was wrong. Using an imported HD-DVD from USA solved the problem, because the key of the disc was already in dumphd's keydb.cfg file.

I was able to play the dumped EVO files using mplayer. :)

So now I'm trying to find a way to get the keys of my european HD-DVDs.
Tomorrow I'll get the logfiles of a colleague's anydvd output (he uses winxp) - maybe I'll be able to find a way to extract the key information. ;)

I have gotten a drive myself lately. I am looking into transcoding .evo/.m2ts files for simple playback and smaller sizes. If I find a good solution (not filling up 200 GB of harddisk with uncompressed video that is) I will report back. The solutions I found are not working out of the box :wink:

Great!

I wanted to try some programs out myself but first I want to play around with the aacskeys program now that I have some disks of which I already know the correct vuk keys. So maybe I'll be able to find out how to use it correctly (and what version of it).

The programs I wanted to test are ffmpeg (frontend Winff exists for linux) or mencoder (various guis to try). Both should be able to use the x264 codec that someone over on the doom9 forums developed (afaik) and that is included into mplayer (see mplayer homepage).
Just to give you some hints where you can start searching. ;)

Thanks for giving input to this "project". :)

I would advise against using ffmpeg with x264, because ffmpeg's codec defaults totally suck and configuring x264 correctly with it is a very tough job. And if you use mencoder, output a raw video stream (-of rawvideo -o video.264), because mencoder can't deal well with containers. You can then mux it with audio later, either with MP4Box (media-video/gpac) for .mp4 or mkvmerge (media-video/mkvtoolnix) for .mkv. Emerge mkvtoolnix with the wxwidgets USE flag to get the very nice gui.

In any case, configuring x264 is not an easy task, I would suggest looking at presets on the doom9.org forums.

Thanks gys, I already have x264 settings using mencoder. They are for DVD rips, but they are well tested and with more bitrate should be sufficient for a 2pass encode of 1080i.

My EVA8000 needs .avi or .wmv container. Mencoder does not have a problem with .avi.

What I have to find out is, how to select the correct Video and audio streams automatically, feeding them to mencoder without filling up the harddisk and how to convert the AC3 streams to a DVD compliant bitrate.

So if I buy a computer Blu-Ray drive I should be able to rip Blu-Ray movies and play the files back on the computer with mplayer? Is mplayer the only one that will play them back? How much space should a raw rip take up?

Technically programs like Anydvd HD (windows) are able to copy the data and remove the DRM. For some discs with already known keys there is a program for linux that can do the same.

mplayer cannot play them back directly! To make playback possible you have to trascode them, which consumes 2,5 days (for one pass :roll: ) on my Turion 64 X2 2.0 GHz for a 140 min. movie atm. VLC is in some cases able to play the m2ts files directly (with bad performance atm.) That all depends on the Codecs used on the disc. This is heavy work in progress and assumes you are using the svn versions of mplayer, ffmpeg and vlc.

The rip of the data is between 25 and 50 GB per movie. If you uncompress the video to raw data (like some of the scripts out there do) it's >4GB per minute! Mplayer could play that raw yuv data, but who could store it? :wink:

MPlayer can play the decrypted files directly (you don't even have to rip the disc, DumpHD can perform on-the-fly decryption), but you need to patch mplayer to add the necessary audio decoders. The problem is getting the decryption keys. If they're not on doom9.org, you need a Windows installation and even then, it's not possible to get all keys.

Let me correct myself. Mplayer-svn can playback .m2ts IF they are encoded with MPEG2 or MPEG4 AVC (h.264), but it is a dia show (approx 2 fps with my hardware) and it stops approx 10 seconds into the video when playing h.264. With every VC-1 encoding I have tested playback crashes instantly.

So it is safe to say: Theoretically Mplayer-svn can playback the Streams. :twisted:

As I already stated this is in heavy development.

@cord:
From your list:
Code:
h264  AVC/h.264 elementary streams


This is what "-of rawvideo -o video.264" creates - an elementary stream. "Raw video" as opposed to "encapsulated in container video". What you're thinking of is raw video as in raw uncompressed frames. Different semantics.

The HD-DVD .evo files are playing flawlessly on my AMD X2 4000+ with 2GB RAM.

Haven't tested any BluRays yet. Their encryption is more complicated (BD+) and they have region-codes too. It would be safe to assume that because of the .m2ts container format it will playback .

The evo and m2ts container formats seem both to be very ineffective (but the m2ts of bluray is reported to be worse). A co-worker using the same hardware is complaining about crappy evo playback on win vista too.

Of course recoding will make the performance better and the storage requirements for the recoded files are significantly less.

Hi Guys,
I've successfully ripped a Blu-Ray using VirtualBox, AnyDVD HD, tsMuxeR and mkvmerge.
I know, I know, using windoze is cheating, but as my drive is now locked (see previous posts) I don't really have much choice.

Unfortunately, it doesn't play properly. I get the following error from mplayer:

Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.


I don't think this can be a performance issue, as I've got a reasonably quick system with a GeForce 8500GT in, which is a HDCP capable card so should be able to handle 1080p using only the GPU..
I could be wrong on that, but I've got other 1080p files that play fine.

I haven't recoded the video stream as I want to keep it as high quality as possible, but I have converted the DTS TrueHD audio to AC3.

The AC3 stream plays fine on it's own and when I put the h264 stream into an mkv on its own it appears to play fine as well. It's a little harder to tell if it's stepping without the audio.

Has anyone come across that mplayer error before?
It's a new one on me.

Thanks

Just a guess: it's the -vo module. Try this:
Code:
mplayer -vo gl:yuv=2:force-pbo -dr -noslices yourfile.mkv

You'll need a pretty new mplayer to get the force-pbo option. You could also try a simple "-vo xv", but gl with force-pbo is slightly faster, especially if you're running a compositor.

Cheers mate, that did it!
Are those options specific to HD or can I safely drop them into .mplayer/config?

Now I just need to figure out why the audio's out of sync :(

A little update from my side:

I am struggling with sound conversion atm. My combination of network player and receiver only can play DVD compliant AC3 or DTS. So I have to convert the EAC3/TrueHD or DTS-HD streams to a lower bitrate/resolution and merge them. I already tried ffmepg->aften. The channels got mixed up and I had an audio offset of several seconds.

I also tried converting video with mencoder directly. But it is not the most stable type of conversion. A stream that converted nicely with ldecod->mencoder crashes 200 seconds into the file using only mencoder (but the mencoder only encoding is 2 times faster).

If anyone knows a solution for this problems out of the box, don't hesitate to tell me. :wink:

Making heavy progress.

My script is on a good way. So far it uses ffmpeg, libx264, libfaac and libmp3lame and encodes ripped blu-ray data to .avi, .mkv or .mp4 containers using either h264 or XVID and resolutions of 1080p or 720p.

I am experiencing one error at the moment. The encoded video has a recurring sequence of

single frame - two identical frames - three identical frames - single frame - ...

which leads to a video stream with twice the playtime.

Has anyone experienced something like this before?

For reference, her is my script

#
# This script works best with ffmpeg and x264 from SVN repositories.

# (be sure to have /usr/local after /usr in your path environments)

# get a defined environment. If you don't have this one installed, change to en_US.UTF-8 or something
export LC_ALL=en_US

#change paths if necessary

You have to identify the audio streams you want to use in an external software. I use tsMuxerGUI for that task. Just count the audio streams (starting with 1) and give one or two numbers in the ordering you want them to appear in the output container.

Great! Thanks :)

I'm going to do some heavy testing/experimenting this weekend. Hopefully we'll get some new results.

As mentioned before, the ffmpeg solution above still has a problem in the video part.

For the time being There is a workaround with mencoder. It is a little more handwork though.

1. First you have to remux the .m2ts streams you want into a MPEG4 Transportstream (.ts) using any suitable program. I use tsMuxeR (I use the windows version under wine because the linux version segfaults) with a script generated by tsMuxerGUI.

2. transcode the .ts file using mencoder and x264 to AVI or raw video, Copy audio or convert to AAC

3. convert AVI to mkv using mmg (MKVmergeGUI) or create a .mp4 from the rawvideo using mp4create

This is the script to get .mkv
Code:
#!/bin/bash

export LC_ALL=en_US

help_text () {
cat <<EOF
$0 is used to convert Blu-Ray/HDDVD Rips into a format more playable.
$0 can handle up to two audio streams which can either be copied as-is
or encoded to stereo mp3

usage $0 [-f <fps>] [ -b <bitrate>] filename [audio_id_1] [audio_id_2]
    -f         frames per second of input video (default: 23.976)
    -b         bitrate for video encoding (in kbit/s) (default: 6000)
    -r         full resolution (full HD 1080p) (default: 1280x720)
    -h         print this helptext
    audio_id_x usually a number between 1 and 8
EOF
   exit 0
}

mencoder=/usr/local/bin/mencoder
mplayer=/usr/local/bin/mplayer

BITRATE=6000

  case "$option"

    r)  resolution="1920:1080";;
    b)  BITRATE=$OPTARG;;
    f)  FPS=$OPTARG;;
    h)  help_text ;;
  esac
done
shift $(($OPTIND - 1))


if [ -z $1 ] ; then
   help_text
   exit ;
else
   input=$1
fi

name=`basename $input .ts`

if [ ! -z $2 ] ; then
   num=$(( $2 + 1 ))
   AUDIO="-aid 435"$num
fi

echo $mencoder $input \
         $AUDIO -oac copy \
    -ovc x264 -x264encopts subq=4:bframes=4:b_pyramid:weight_b:pass=1:psnr:bitrate=$BITRATE:turbo=2:threads=0 \
    -vf scale=1280:720 \

    -o /dev/null

   num=$(( $3 + 1 ))
   AUDIO="-aid 435"$num
   $mplayer $input $AUDIO -dumpaudio -dumpfile $name"_"$3".ac3"
fi

mmg   


To get mp4 you need these two scripts
Code:
#!/bin/bash

export LC_ALL=en_US

help_text () {
cat <<EOF

I found some (new?) software for decrypting HD and Bluray media.
It is win software but claims to work with wine, as you can see here. The best of it seems even to be free (as in beer ;))

The only thing that it is not (yet) able to do is decrypting BD+ protected discs.

I'm going to try it out asap.

I've known about DVDFab for quite a while. I use it to decrypt DVDs (those with "protections" that linux rippers can't handle). It can only handle MKBv1 and MKBv3 discs, so it's of limited use.

But even if it's of limited use for HD, I can only recommend it for DVDs, it's nice and works very well.

I didn't know they actually advertised linux via wine support. I find it kinda funny. But oh well, maybe it gets them a few customers for the Platinum edition.
