View source for I420

===A historical anecdote===
For a very very long time MeGUI had a funny bug where it would complain about the script's output not being YV12, and offering to add ConvertToYV12() to the end of it for you. If you accepted its offer, it'd add ConvertToYV12() and then immediately pop up the same warning again. This would continue ''ad infinitum'' until you told it to stop. It'd then work just fine. This bug was eventually "fixed" by adding a "don't ask again" checkbox, and was left in that state for about two years until someone pointed out the difference (or perhaps the similarity) between YV12 and I420 to the MeGUI authors. Since the script output was I420, and the MeGUI authors didn't know what to do with that, they tried to add ConvertToYV12(), but that's a no-op on I420 and so the output format remained the same.

The moral of this story is that ''the definition of insanity is doing the same thing over and over and expecting different results''.<br />
(Attributed to Albert Einstein as well as to Benjamin Franklin and Mark Twain).
