Neil deGrasse Tyson posted a video on his blog today and I wanted to watch it on my mobile phone.
I could have just watched it because its very small but no, I realy wanted the video offline.

And lucky us, ooyala provides a link to embeded the video, in such a way, that we have a direct link to their playlist. or apparantly, a m3u8 is a kind of stream playlist.
Some google and bing minutes later and I got the following website:
http://forum.videohelp.com/threads/359319-How-do-I-download-the-following-m3u8-url
basicly saying:
ffmpeg can download it with the following command line:
Code: ffmpeg -i inputvideo.m3u8 outputvideo.ts

So yes, after I downloaded ffmpeg (realy handy) I later got a ts file, thats basicly a mp2 file like settop boxes use for streams.
altho I could have tried converting the file, windows mediaplayer and VLC just play it.
and while I copied the file to my Windows Phone 8.1, he said "This device does not support playing this file, would you like to convert it?" I clicked yes and there was a WMV file, with audio and video on my mobile :D

Thanks for reading, the more you know :D
