Wishmaster I will not cover how to decrypt. This tutorial will be in 2 parts: Part 1: Installing,setting up,and configuring everything needed as well as the configuring the encoder itself. Part 2: The actual encoding process. Theres alot of info. to cover so lets get started. Step 1: The Essential Tools & Utilities 1) Shark007's Codec pack (optional) If you plan on using WMC for playback, and wish to use FFDshow as the decoder, you will need the 64bit add on as well. However, for the purposes of MeGUI, only the 32bit package is needed. [Please Note] You do not actually need any 3rd party Codecs such as FFDShow or Sharks codec pack. Both DVD and BluRay can be indexed and encoded with built in codecs. Extracting BluRay video streams to MKV format is the easiest way to work with them. You will need Haali splitter for these MKVs but if using Shark007s package, it is included.. You will need it only if you decide not to use this codec package.

  • X264 Video Encoding Frontend
    x264 Video Encoding Frontend By Alvin Lam California Polytechnic State University Computer Science Department June 1, 2015 Abstract x264 is a free video codec for encoding video streams into the H.264/MPEG- 4 AVC format. It has become the new standard for video encoding, providing higher quality with a higher compression than that of XviD.1 x264 provides a command line interface as well as an API and is used in popular applications such as HandBrake2 and FFmpeg3. Advanced Audio Coding (AAC) is a very popular audio coding standard for lossy digital audio compression. AAC pro- vides a higher sound quality than MP3 at similar bitrates.4 This senior project describes the design and implementation of a x264 video encoding frontend that uses these codecs to encode videos. The frontend provides a simple and easy-to-use graphical user interface. Subtitles are preserved across encodes and the resulting encoded file is stored in a Matroska container format. i Acknowledgments I would like to thank my project adviser Dr. Gene Fisher for his support and guidance throughout the entire project. I would also like to thank Gaurav Singh (fOOt) for letting me join his encoding team and introducing me to encoding in the first place. Lastly I would like to thank Vörös Szebasztián (durzegon), Mike Andries (Maiku), and the rest of the team for being such great software testers and for demanding even more features. ii Table of Contents 1 Introduction 1 1.1 Problem Description . 1 1.2 Project Overview . 1 1.3 Encoding Process . 2 1.4 Outline .
