MKMP4: An automated H264 / HE-AAC (aacPlus) encoder script for Mac and Linux / Unix

Friday, September 26th, 2008

I have been nothing but amazed about the feedback that i got on my prior tutorials on how to automate the whole chain of free and open source tools to create amazing quality video at really low bitrates (great for flash streaming, etcetera).

I usually write such tools and scripts for myself or for clients, but due to the fact that it seems a lot of people is interested in the process, I’m releasing here the new version of my encoding tools for the Mac and any Linux / Unix variant.

Needed tools and applications

For all this to work, you will need the following things

Extra pre-requisites for Mac OS X

Mac OS X users need to install the Apple Developer Tools (aka XCode) in order to compile software, also, for building the x264 encoder, you will need to get and install YASM.

Now, you have to build and install all the tools, AND they have to be on any directory in your executable path. My scripts assume that all the tools are in your executable path.

Update Notice

This post has been updated with a newer and improved script and instructions, please visit the new one HERE.

It was some months ago when I wrote a tutorial about how to encode good quality h.264 video with aacPlus audio in order to use the great capabilities of the new flash player version 9.0.115 (that in case you missed it, now can play h264 video and aacPlus v2 audio).
Due to some personal convictions for my prior tutorial, i decided to use FFMPEG, and while it does the job pretty well, it has some limitations (specially in the video scaling / resizing area). So in my particular case, I had to use several php / bash scripts in order to feed the encoders with the proper resizing data, etcetera.
Well, let me introduce you to the 2nd version of my h.264 / aacPlus v2 tutorial.

This time I used Mencoder, an amazing tool that comes with the mPlayer package, and i also created what i think is a really nice bash script to make the process almost 100% smooth and simple.

These are the things you will need:
