[Chromium](https://www.chromium.org/Home) is an open-source web browser project that provides the source code for the proprietary Google Chrome browser. Taking into consideration some privacy issues (for example it does not contain [RLZ identifier](https://blog.chromium.org/2010/06/in-open-for-rlz.html)), Chromium might be an interesting alternative to Google Chrome web browser.
Here's a [link](https://en.wikipedia.org/wiki/Chromium_(web_browser)#Differences_from_Google_Chrome) to Wikipedia's comparison between Google Chrome and Chromium web browsers.
# Why this How-to?
There are several places on the Internet where we can download Chromium build. Unfortunately, due to some licensing issues, those builds does not/can not contain several important audio-video codecs Google Chrome has. That makes those builds rather useless. But there's a good news too. Licensing allows to compile our own build of Chromium with those codecs. The only obstacle is that finding any information how to do that successfully is rather difficult task.
This document shows how to compile OS X Chromium with all proprietary codecs.
# Before we start
Read Google's instruction called [Checking out and building Chromium for Mac](https://chromium.googlesource.com/chromium/src/+/master/docs/mac_build_instructions.md). It describes all of the main steps necessary to make a Chromium build.
Below I will show you how to modify those steps to incorporate proprietary codecs to our build.

1. Ensure that unicode filenames aren't mangled by HFS and clone the depot_tools repository:
