    Do i hv to install URPMI program???

    B'coz wen i m typing urpmi konverter in the terminal its saying

    "bash: urpmi : command not found

    I suggest you use Mandriva Control Center instead, Software section; it's all GUI.

    Can't read DVD [solved]

    in Software

    When you are selecting the disc type in Nero, make sure the box labled 'No Multisession' is checked. This will ensure that your discs are finalized and you should be able to read them on any other OS.

    The fact that you use one or more sessions, and the fact that the latest session is closed or not, are completely independant. Actually, I'd expect a much lower chance of having an unclosed session when using multi-session.

     

    May B its b'coz i hvn't burned it in ISO format. all my DVDs r burned in UDF file format, i think thats the reason Y mandriva is not able to read it.
    Don't worry, UDF is read fine by any recent distro (I assume we're talking about a data or video DVD, not a distribution DVD ISO file). Your problem shouldn't relate to UDF.

    Can't read DVD [solved]

    No offense taken :)

     

    Ok i think you are not a windows user.
    Indeed I'm not, not even at work now.
    if you are then you must be knowing about NERO burning ROM
    Yet I know of this software (much like K3B, or the other way around actually).
    i used that software to burn the DVDs and now linux is not able to read that not even a data disc containing mp3 files.

    As far as I know, Nero allows to burn "unfinished" DVDs, like DVD recorders do, and Windows can read them! I don't know the details, but basically, the burning session is left open, for more data to be appended later (or even changed, with RW) into the same session, so that the multi-session recording technique isn't needed, this latter technique wasting some media space at each new session.

    Alas, as I said, to my knowledge, Linux can't read such DVDs.

    it is really getting my nerves
    We're here to help, if we can :)

    I forgot to mention that tv.sh is graphically interactive when at least the second argument is empty, using "zenity", which must be installed. "amixer" must be installed too.

     

    For those interested, here's a little dictionnary:

     

    ou = or

    pour = for

    d'/de = of

    l'/le/la = the

    du = of the

    à = to

    en fait = in fact

    VHS ≃ VCR

    par defaut = by default

    canal/chaîne = a channel

    rien = nothing

    interractif = interactive

    fichier = a file

    enregistrement = a record

    enregistrer = to record

    duree = amount of time

    optionnel = optionnal

    n'importe quoi = anything

    différent de = different from

    titre = title

    choix = choice

    num = # (number)

    nom = name

    attente = now waiting

    cliquer = click with the mouse

    début = the start

    fin = the end

    commencer = to begin

    arrêter = to stop

    Of course, you'll have to adapt the general settings (vo=…) and each profile (device=…, input=…, normid=…, channels=…, mixer-channel=…).

    For me, .mplayer/mencoder.conf is a symbolic link to .mplayer/config.

     

    Now tv.sh:

    #!/bin/bash

[ -n "$4" ] && sleep $4 || zenity --info --title 'Attente de la fin' --text "Cliquer pour arrêter d'enregistrer..."
kill $pid

amixer set $mixer mute

    Adapt "mixer", and "DIR=…" (where records are stored in interactive mode).

     

    And tv-PAL.sh:

    The same for PAL (on the s-video input).

    VCR Video to Hard drive

    in Software

    OK. Let's go :)

     

    In France, we use SECAM, which uses the same resolution as PAL: 576 lines, split into two frames of 288 each. There are 25 images per second, which makes 50 frames per second. Someone told me that with analog signal, there's no such thing as "horizontal resolution", so I work with 384 columns; that way each frame is 4/3: 384x288 (768 would be nice but salon's CPU doesn't have enough power).

     

    I defined 2 record qualities:

    - "low": 384x288 @ 25fps: I let the hardware deal with deinterlacing, be it by some calculations, or by skipping every second frame, I don't know.

    - "high": 384x576 @ 25fps: I get the whole data, but each picture is interlaced, so the software has to deal with that.

     

    My capture card has three inputs: video, s-video, and tuner; I use the latter two.

    Basically, I have two scripts: tv.sh, and mk_enc_script.sh.

     

    tv.sh e {0|1|2|3|4|…} /path/to/raw/record.avi timeToRecord [HQ]

    'e' stands for "encode", because there's also 'p' for "play" (fake; chech we have both sound and picture).

    Next comes the channel (they are defined in the script). 0 is special for s-video.

    The timeToRecord is the encoding time in a format accepted by "sleep": 1.5h, or 125m, etc…

    the "HQ" word is present or absent depending on which quality I want.

    Depending on the parameters, one of 4 profiles defined for mencoder/mplayer is used: tuner, tuner HQ, s-video, or s-video HQ.

    This script creates a "raw" video, well… AVI, but with as little treatment as possible with the hardware I have: this takes rougthly 4 to 5 GB of disk space per hour of record.

     

    The second script needs polishing and is only suitable for ISO MPEG 4 results. For it to work correctly, the "record.avi" file must be placed in a folder called "record" (same as the video without the extension). It needs some data that I get using avidemux.

    So I open this video in avidemux. I skim over it to locate the start, end, and interruptions, and I report all "cuts" in a file called "record.edl" (same as the folder, with the .edl extension).

    For example, let's suppose we see in avidemux that the video beging at frame #578, and there's advertisement starting at frame #70432, and the film begins again at frame #85490, and the film's last frame is #162065. I would create an EDL file with this contents:

    0 578
70432 85490
162065

    I'm not done yet with avidemux. I open the video filters dialog, "crop" category, and I choose the cropped width, height, and X/Y offsets (I'll name them W, H, X, Y) this way:

    - All border-garbage or black borders should be removed.

    - W, H, X, and Y should be even numbers only, although uneven X or Y seem acceptable.

    - W and H should each be a multiple of 16 pixels.

    - For interlaced video (my "high" quality), W should be a multiple of 8.

    - For interlaced video (my "high" quality), X and Y should each be a multiple of 4 pixels.

    I run the second script like this:

    mk_enc_script.sh path/to/record/folder X Y W H [HQ]

    The trailing "HQ" word is present only if the "raw" AVI was recorded in "high" quality.

    The script assumes I want to create a MPEG 4 file that would fit on a 700MB CD, and displays 3 different possible settings for audio and video. I choose the one that fits best the kind of film I encode (musical: good audio bitrate, action: good video bitrate).

     

    The result of the script is another (generated) script named "record.sh" ("record.edl" is also transformed in the process); "record.sh" will launch mencoder with a suitable EDL file, and suitable parameters. "record.sh" may be launched immediately, or reviewed and tweaked if needed.

    This last script results in a file named "Z.record.avi": the final two-pass-encoded film.

     

    I plan to improve mk_enc_script.sh, so I can tell if the film is anime or "real picture" (easy; results in slightly different parameters for mencoder), and transform mono to stereo.

     

    I'll post the scripts when I get home. Meanwhile, you may be interested in

    Hi John,

     

    I've done a lot of this, and I still am. I create SVCD, DVD, and ISO MPEG 4, depending on the intended usage, and depending on how much I value the record.

     

    I'll share my experience with you if you want, but it is 99% CLI… I'm not saying it is the only way, or even the best, but I'm comfortable with the CLI, and I like to be in control of the whole process. You only got one answer, so I thought you could be interested.

    Kernel patching for UDF 2.50 and Blu-ray

    in Command Line, Kernel and Programming

    Posted

    1. You're using a Mandriva kernel: 2.6.22.18-server-1mdv. So installing the "kernel" package with the same version, and "source" in the name should give you the same kernel with the same config. But your patch may not apply cleanly, or at all, with this kernel. If so, you can try to get latest kernel from kernel.org, and issue this command:

    zcat /proc/config.gz >/path/to/kernel/source/tree/.config

     

    2. No, but I don't remember the details. Fortunately, the kernel source tree contains good documentation about the way it should be built and installed.

     

    3. No.

    Directory permissions for group

    in Command Line, Kernel and Programming

    Posted

    You understand correctly, javaguy. Just one thing is missing, I think: You have the right to see the contents of this directory, but do you have the right to access it?

    To access directory /home/photo/Pictures, you must have the execute permission on directories /home (which I guess you have) and /home/photo (which I guess you don't).

     

    However, granting this execute right won't last long, I think, because msec is probably configured to reset that. So you'll have to decide wether you want to:

    - change msec configuration, or

    - move Pictures somewhere else and maybe change /home/photo/Pictures into a symbolic link to the new location.

    I don't think the exit button can be at fault. Apart from bad luck, I don't see what could have caused your problem…

     

    As for 'Ctrl'+'Alt'+'-', it is indeed a nice trick to know. Unfortunately, it won't keep your prefered resolution between reboots. For that, look at "gnome-display-properties" (Gnome), krandrtray (KDE), or xrandr (generic).

    Very selfish suggestion :cheesy: :

    I'd love to see a place where I can get help about audio and video processing in Linux:

    Steve, your problem could be a lens focus setting or rotation speed setting that has slightly shifted with time.

    I have this problem at home, were my salon's CD drive doesn't burn anymore, and has more and more difficulties in "seeing" inserted media. Often, it won't see a DVD, and I have to open the tray, shift the media a bit to present it at a different angle, and close the tray again a couple of times before it painfully manages to see the media.

     

    I've often had this problem with aging music CD readers, except with these I know how to open them apart and turn the right "potentiomètre" to set the acuracy right again.

     

    Yves.
