Okay, the above is the avi file you made by using ffmpeg to conver the m4v |

I had no idea what the ISO Media format is, so I read about it here: |
12 |
|
13 |
http://en.wikipedia.org/wiki/ISO_base_media_file_format |
14 |
|
15 |
Now I know almost as much as I knew before :p |

This excerpt seems significant to me, however: "ISO base media file format |
18 |
is directly based on Apple’s QuickTime container format". That makes sense |
19 |
because iTunes is mentioned in the same breath as ISO Media. |

My theory is that Steve Jobs is now riding high and wants to displace M$ |
22 |
as the 800-pound-standards-dictating gorilla. |
23 |
|
24 |
Apple has always been smarter than M$, so I'd rather see Apple dictating |
25 |
standards, but dictators are still dictators, and Jobs is as ferociously |
26 |
closed-shop as Gates and Ballmer ever were. (When is google going to |
27 |
publish an extensible open-source multimedia format? Android almost forces |
28 |
them to do it, IMHO.) |

I haven't a clue what that means, unless maybe any multimedia file |
36 |
from iTunes wants to authenticate with an iTunes server before the |
37 |
file can be played? I have no idea. |

Anyone else? |
