[Libav-user] Updated libav/ffmpeg tutorial

[Info || Non-Lethal Applications]

Stephen,

> It's only reliable in the sense that I tried running it, and the audio matched what was being shown on the screen. I'm sure there are better techniques; I haven't yet done the work of going through ffplay.c and seeing what has changed in terms of technique. (The original tutorial was basically copying the code in ffplay.c back then, too.) Thanks to wm4 for simple changes I can make immediately! 

I gotta say: big up for your tutorial and that you’re now updating it.
I’m sure I’m only one among many who learned how to use FFmpeg with your tutorials.
I think they’re especially valuable when you don’t have a lot of experience with digital audio/video.

Keep up the good work!!
