Setting up Stepmania to look/feel like DDR Extreme

The first time I played DDR was on a 6th Mix DDR MAX cabinet, but I spent most of my time with this massive custom LED wall screen that housed DDR Extreme. So when I got a foam pad for home, I wanted to replicate what felt most comfortable.

I'm sure it's not pixel perfect, and there are probably some arcade features/behaviours I'm missing, but this setup is close enough for me!

1. Download Beware's Stepmania Extreme build (direct)

If you don't mind using an older version of Stepmania, you're probably good to go and can ignore the rest!

In this configuration, DHCP will run on the OpenWrt Box, while the TFTP server (the one serves the boot files) runs on a different computer.

1. Add to /etc/config/dhcp on OpenWrt Box

config boot linux
        option filename 'pxelinux.0'
        option serveraddress '192.168.?.?'
        option servername '?'

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".
