       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
       software. As well as creating a simple interface	for those scared of
       getting down and	dirty with MEncoders command line interface, It	also
       automates the process in	a number of ways:

       o   Parses DVD into contents tree

       o   Finds longest title

       o   Calculate video bitrate for given filesize

       o   Finds black bands and crops them

       o   Divides long	films into multiple files

       o   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:

	   o   %T - Title of the track,	as in the editable box above

	   o   %N - Number of the selected track - useful for batch encoding

	   o   %L - Length of the selected track

	   o   %f - The	first letter of	the title [useful for organisation]

	   o   %b - bitrate of the video stream

	   o   %l - language of	the audio track

	   o   %w - width of the video output

	   o   %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
	   support 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
	   boundaries, 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
	   deinterlacing, 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
       automatically 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	(~/ 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

	   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
	   guarentee 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 tracker.
