Mjpeg tools for windows

[Creed92]

Hello to everyone
I want to try this software because I read various positive reviews, expecially for his amazing multiplexer (mplex.exe)
I have windows xp, there's a windows version of the program?

[Baldrick]

You can download the bz2 file from http://sourceforge.net/projects/mjpeg/files/mjpegtools/2.0.1rc1/

Extract the content from the bz2 and tar file with 7zip. You will find the mplex.exe in the bin folder.


I added a zip mirror also: www.videohelp.com/download/mjpegtools-2.0.1RC1-mingw-bin.zip

edit: Note that they are command line software.

Thanks a lot!!!
Now I need a guide or something, because I'm a total newbie for command line programs... only a simple guide for demuxing command (if there is) and mplex.exe command
PS: command line means that I use the ''command prompt'' tool of windows, right?

[Baldrick]

Simple and command line doesn't mix that well. .

Do you really need to use it? I think the basic dvdauthorgui uses mplex.exe to mux.

[Creed92]

Well, I want to learn...

[Creed92]

For example, what command do you use usually?

[Baldrick]

First google command line tutorials.

Then google mplex examples:

mplex -f 8 -o output.mpg video.m2v audio.m2a

Done.

[Creed92]

This is the command prompt.
I have the mjpeg tools on C:
m2v and mpa files in the other hard disk

So now what command I must write?
Please help, no tutorials I found on the internet

[poisondeathray]

For command line, use quotation marks with the directory path eg. "C:\directory\folder\..."

e.g.

"C:\mplex" -f 8 -o "PATH\output.mpg" "PATH\video.m2v" "PATH\audio.m2a"

Replace "PATH" with the real directory path

Note there are easier multiplexing tools to use with GUI's like ImagoMPEG-Muxer , or muxman

[Creed92]

"C:\mplex" is not recongnised as a command

[poisondeathray]

"C:\mplex" is not recongnised as a command

change the directory to wherever you put mplex.exe

"c:\PATH\mplex.exe"

[Creed92]

Job done Thanks
It's easy, but I have one question: there are other options that I can insert in the command? Like Variable Bit rate, Mpeg-2 program stream.... etc
or simply there's no need to put them?

[poisondeathray]

-V for variable bitrate

have a look at the instructions and documentation for the other options and switches

for most command line tools its -h , or -help

there is a pdf you can download
mjpeg.sourceforge.net/files/mjpeg-howto.pdf

[Creed92]

That pdf explain how to create a mpeg-2 file from mp3 files, while I want to recreate the same file demuxed... so I need to know what commands can do that (VBR, size same as source, etc..)

[Creed92]

On Gspot and Mediainfo the file appears already like an MPEG-2 PS VBR... what this means? Maybe there's no need to specificate VBR because the original video demuxed was already with VBR?

[poisondeathray]

I think you need -V, otherwise it will pad the stream (CBR mux, will become larger filesize with wasted bits)

Read the instructions, it's in the PDF

I don't use mplex, so test it out

[Creed92]

-V instead of -f ??
-o and 8 stands for what?

[poisondeathray]

-f 8 is for dvd according to the instructions (it is possible to mux streams that are non DVD compliant)

-V is for VBR according to the instructions

Maybe you should read the instructions ?
mjpeg.sourceforge.net/files/mjpeg-howto.pdf

Maybe -f 8 includes VBR muxing, not sure, I don't use it

The −V option tells that your source for mplexing is a VBR stream. If you don't use this option mplex creates
something like a CBR Stream with the bitrate you have told it with the −r option. These streams are usually
get BIG.

DVD Mplex Example
> mplex −f 8 sound.mp2 video.m2v −o my_dvdlikestream.mpg
−f 8
Here again we specify that we want to have DVD like MPEG stream.

[Creed92]

So the only thing that I must to do is insert -v ; -f ; -o and 8 ? no other commands right? because I need the file same as source
Thanks a lot!!
