        acidrip - a Gtk2::Perl wrapper for MPlayer / Mencoder




        AcidRip is a Gtk2::Perl application for ripping and encoding DVD’s and
        other media files. It neatly wraps MPlayer and MEncoder, which is
        pretty handy, seeing as MPlayer is by far the best video player soft‐
        ware. As well as creating a simple interface for those scared of get‐
        ting down and dirty with MEncoders command line interface, It also
        automates the process in a number of ways:
        ·   Parses DVD into contents tree
        ·   Finds longest title
        ·   Calculate video bitrate for given filesize
        ·   Finds black bands and crops them
        ·   Divides long films into multiple files
        ·   Other stuff!


        Some simple steps to ripping with AcidRip:
        1 - Load DVD or file
            To load a DVD, press "Load" with the disk in your drive (after
            checking that the device is correct. You might want to symlink it
            to /dev/dvd).  To load a file, or a whole directory, enter the
            location in the "Path" box and hit Load.  This loads contents and
            displays it as a tree of tracks (and chapters for DVD). The longest
            track, assumed to be the main feature, is automatically selected
            for you. If you wish to only encode certain chapters of a DVD
            title, just expand that branch and click on the first and last
            chapters you want, while holding shift.
        2 - Choose correct file name and desired size
            The name of the output file is defined by a number of variables:
            ·   %T - Title of the track, as in the editable box above
            ·   %N - Number of the selected track - useful for batch encoding
            ·   %L - Length of the selected track
            ·   %f - The first letter of the title [useful for organisation]
            ·   %b - bitrate of the video stream
            ·   %l - language of the audio track
            ·   %w - width of the video output
            ·   %h - height of the video output
            For example, "/var/film/%f/%T-%N-%wx%h" might be evaluated to
            Also select a file size. This is used to calculate bitrates for the
            codecs you are going to use. If the codecs you choose do NOT sup‐
            port a bitrate option (e.g copy, rawrgb etc. for video) then the
            given size can NOT be enforced at all.
            A film can be split into a number of files by setting a value in
            the relevant box. The created files are split by chapter bound‐
            aries, so the chapters must be suitable.
            You can also add additional information, akin to the ID3 tag’s in
            MP3s. Choose the field in the combo box and enter the correct
            value.  Few players other than mplayer use this information though.
        3 - Choose audio track
            Select the language for the audio. You may also have the option to
            encode directors commentary etc., however the tracks will only be
            listed as such if the description is actually on the DVD itself,
            which doesn’t seem to happen that often.
        4 - Choose audio output
            Use the combo box to choose how to encode the audio. normally this
            should be an MP3 stream. If you do not have mp3lame listed in the
            codecs combo box then you need to compile it into mencoder, it is
            nothing to do with acidrip at all. If you choose mp3lame set your
            options in the box below. See the mencoder manpage for a list of
            options (look for "lameopts").
        5 - Choose video output
            Select the desired video output. lavc (FFMpeg’s avcodec libraries)
            is the default choice. Despite what you might assume "vcodec=mpeg4"
            relates to divx4/5 encoding, trust me on this one..! Many people
            prefer Xvid encoding, it’s up to you of course. Set any options
            specific to the selected output in the options box below. See the
            relevant entries in the mencoder manpage for the full selection.
            Only defaults for lavc are provided. The three main codecs can also
            use 2 pass encoding, select the option if you wish to encode the
            film twice to improve quality.
            You should also check the bitrate here. This value is based on the
            desired file size and the selected audio bitrates. You may wish to
            enter your own bitrate and lock the value using the check box to
            ensure that it is not changed. This naturally means that the file
            size can not be guarenteed.
        6 - Crop film
            Assuming you are using a proper encoding codec (lavc / xvid / divx)
            then you should want to chop off any widescreen bars and such like.
            These bars just soak up disk space, leaving less for the actual
            film. Just pressing the "Detect" button should suffice, but it’s a
            good idea to check the results to make sure, and adjust the values
            accordingly.  Pressing the "Detect" button uses mplayer to pick
            frames throughout the DVD and analyzes it for unwanted areas. Note
            that the values for cropping are not related at all to the output
            size, but instead the size of the DVD itself (720x568 for PAL,
            720x480 for NTSC).
        7 - Scale film
            The final output dimensions of the film can now be set. By default
            the height is locked against the width setting in line with the
            aspect of the video (including any cropping to be applied). The
            scaling of the film is most likely to affect the BPP (Bits Per
            Pixel) values of the file. For a typical divx film you want about
            0.17 - 0.20. A value higher than this just wastes space: divx just
            doesn’t *need* it..., a lower value and the output is blocky and
            poor. By adjusting the width of the film you can affect the BPP
            value directly. Obviously file size and crop values can also affect
            the BPP among others.
        8 - Filters
            You can now enter any flags for processing the film, such as dein‐
            terlacing, deblocking etc. See the mencoder manpage for details.
            There are no set options other than a default "pp=de" as you should
            only use the options if you know what they are there for. rtfm!
        9 - Encode
            Everything should be set up now so press the "Start" button and
            make some tea.
        That is all that should be required to rip a DVD or file(s). However
        you should not need to perform each step every time. By saving your
        settings they will be automatically loaded next time, and if "Autoload
        media" is selected in the "Additional settings" dialog then the DVD /
        file / directory will be automatically loaded for you. Further more is
        autoload is set, and cropping in enabled then it will be cropped auto‐
        matically too. After this, all you should ever need to do is that press
        start. One button!


            Acidrip has the ability to build and process a queue of events.
            Clicking on "Queue" rather that "Start" will take the current
            encoding settings and create the commands as normal but then add
            them to an execution queue which will not be executed until the
            "Start" button is pressed. The queue can also be exported to a
            standard bash script (~/acidrip.sh) to execute outside of acidrip.
            There are a number of other additional features in the "Additional
            settings" dialog window. These are:
            Mencoder / Mplayer / lsdvd entries: Change the default program
            names / locations. Allows you to set default parameters not handled
            elsewhere, or set something such as changing "mencoder" to "nice
            mencoder" to run the program via nice.
            Cache DVD / Delete Cache: Values used in caching a disc. Firstly
            the directory to place the cached track in, wether to cache at all
            and wether to automatically delete the cache after encoding. NB.
            you do NOT NOT NOT *need* to cache a DVD at all, you jsut might
            want to.
            Language: The default ISO639 language code or full language name to
            use, e.g. en, de, English...
            Overwrite files: Movie files will be overwritten if they aleady
            Shutdown: Attempt to shutdown system after completion.
            Compact progress dialog: Hides the main window while encoding, and
            only shows the encoding box by itself. There is no "Stop" button
            etc, so as well as the smaller footprint you can’t stop it by mis‐
            Enforce size check: The file size value set will turn red if there
            is apparently not enough space in the provided output directory. As
            the file size value is only used as an estimate and does not guar‐
            entee a fixed output size, you may well know something acidrip
            doesn’t, so you can allow the program to encode regardless if you


        Please report any bugs or functional inconsistencies by email or on the
