Short Chromium rant
In 2011, Google announced plans to remove H.264 from Chrome. They were terrible plans with no practical upsides for anybody apart from Google. H.264 is used everywhere, and three years later Chrome still supports it.
What is gone, though, is Chromium’s support for H.264. If you use Chromium you have to compile in support for the Web’s most popular video codec. So I did that — it’s not at all hard, just time-consuming. If you’d like to save yourself the pain, and use a Mac, I’ll send you a copy.
