README for the TOOLS directory
==============================
Preamble
--------
In this directory you can find some nice scripts and code that makes
using MPlayer and MEncoder easier, for example scripts for DVD track
encoding in three pass mode or creating SVCDs from a movie.
MPlayer scripts in the TOOLS dir
--------------------------------
midentify
Author: Tobias Diedrich
Description: Runs 'mplayer -identify' for all arguments while preventing
video window flashing.
Usage: midentify file1 [file2 ...]
mpconsole
Author: Rich Felker
Description: Script to run MPlayer on the console (fbdev/mga_vid/etc.) without
the console text and/or flashing cursor getting in the way.
Usage: mpconsole [mplayer options]
mplmult.sh
Author: Reimar Döffinger
Description: Example how to output video on multiple windows in sync. Might
be even more useful in combination with -vo ggi to distribute
the video arbitrarily.
Usage: mplmult.sh <n> <options>
n number of MPlayer instances that display the video
options any options you would pass to MPlayer, more than
one file will usually not work
x2mpsub.sh
Author: Gabucino
Description: Converts the subtitles in the current directory into MPsub
format (subtitles go in ./converted-subtitles/).
Usage: x2mpsub.sh
mp.pl
Author: Felix Bünemann
Description: Small helper script that allows to play multiple files with
MPlayer. Wildcards are supported.
Usage: mp.pl <parameters> <files>
Where <parameters> are all possible command line switches
for MPlayer and <files> can be either a list of files,
like file1 file2 file3 and/or a wildcard definition,
like *.avi.
example: mp.pl -vo x11 /dvd/VIDEO_TS/VTS_05_*.VOB movie.asf
wma2ogg.pl
Author: Peter Simon
Description: Converts WMA files to Ogg or MP3.
Usage: wma2ogg [options] <-f FILE1 | -f FILE2 ... | -a>
-f, -file filename
-a converts all WMA files in the current directory
-t output filetype (ogg, mp3) [default=ogg]
-lame I wanna use L.A.M.E. sure enough!
-br bitrate (kb/s) [default=from the WMA]
-del remove WMA file(s) after the transcoding
MEncoder scripts in the TOOLS dir
---------------------------------
divx2svcd
Author: Miklos Vajna
Description: A simple utility that creates an SVCD from a video in an AVI
container.
Usage: divx2svcd <input_avi> [options]
see 'divx2svcd -h' for more info
mencvcd
Author: Jürgen Hammelmann
Description: Converts DVD (or anything else that MPlayer plays) to (S)VCD
Usage: mencvcd <basename> [mencvcd options] [mplayer options]
see 'mencvcd -h' for more info
Note: Requires MPlayer, mjpegtools, VCDImager, cdrdao, and optionally
LAME, tooLAME and SoX.
dvd2divxscript.pl
Author: Florian Schilhabel
Description: Yet another DVD to divx helper script.
This script encodes a DVD track in three pass mode to MPEG-4 with
libavcodec. Optionally it writes the resulting movie file to
CD-ROM the corresponding audio track to MP3. It can also shut
down the computer when it finishes. If you like, you can
watch the MEncoder output on /dev/tty8.
Usage: --help show help
--abr (AudioBitRate) Please enter the desired bitrate this
can be either [96|128|192] kbit/sec (default: 128).
--lang Specify the Language of the audio track this can be
for example <en> or <de> (default: <de>).
--dvd Specify the DVD track you want to encode.
--cdsize Specify the size of your CD-ROM (default: 700MB).
--shutdown Shutdown the system, when the encoding process has
finished. Needs appropriate privileges.
--out Specify the name of your encoded movie. The file
extension will be appended automatically.
--writecd Takes the newly created movie and writes it to a
CD-ROM.
--writedev cdrecord device identifier, for example 0,1,0
--speed writing speed (default: 4)
--dvd-device device to pull the video off (default: /dev/dvd)
Tech scripts in the TOOLS dir
-----------------------------
fastmem.sh
Author: Arpi
Description: benchmark/testbed for fastmemcpy stuff
Usage: fastmem.sh
sws-test
Author: Michael Niedermayer
Description: Very simple script to generate PNG images from a video with all
-sws methods.
Usage: sws-test <video-file> <start-pos> <res>
example: sws-test abc.avi 10 160:120
calcbpp.pl
Author: Moritz Bunkus
Description: A script that calculates the $bpp for a movie, mentioned in
DOCS/tech/encoding-tips.txt, see that document for more info.
Usage: calcbpp.pl <resolution> <aspect ratio> <bitrate> <fps>
resolution: the cropped but unscaled resolution
(use '-vf cropdetect')
aspect ratio: the encoded aspect ratio. All DVDs come at
720x576 but contain a flag that tells the player
wether it should display the DVD at an aspect
ratio of 4/3 (1.333) or at 16/9 (1.777). Have a
look at MPlayer's output - there's something
about 'prescaling'. That's what you are looking
for.
bitrate: the video bitrate in kbit/s
fps: the fps
example: calcbpp.pl 720x440 16/9 896 25
countquant.pl
Author: Moritz Bunkus
Description: Counts the quantizers used for the encoding, mentioned in
DOCS/tech/encoding-tips.txt, see that document for more info.
Usage: countquant.pl < divx2pass.log
It will print out which quantizer was used how often. If you see
that e.g. the lowest quantizer (vqmin=2) gets used for > 95% of
the frames then you can safely increase your picture size.
perlbench.pl
Author: Felix Bünemann
Description: fastmemcpy benchmark script
Usage: perlbench.pl
plotpsnr.pl
Author: Jonas Jermann
Description: Draw PSNR log graphs using gnuplot.

-h, --help Display this help message
-quant Display quantizers
-size Display size
-psnr Display PSNR
-iframes Display I-frames
-pframes Display P-frames
-bframes Display B-frames
-aframes Display all frames in different colors
-cmp <file2> Compare two files
-qs <style> Quantizer style
-ss <style> Size style
-ps <style> PSNR style
Default: -quant -size -psnr -qs "p" -ss "i" -ps "p"
Note: Requires gnuplot. Comparison is based on file2. Comparison
assumes that the frame numbers of both files fit.
asfinfo
Author: Arpi
Description: a simple ASF header display program
Usage: asfinfo <filename.asf>
Note: Also see MPlayer's -identify option.
avi-fix
Author: Arpi
Description: A simple tool to fix chunk sizes in RIFF AVI files.
