If you want to use libav* to decode the video in your own program, you
certainly can do that. When you open a "file" you pass it a URL (if
it's just a file on your local hard drive, you can pass something like
"video.mov" and it will open it with the file protocol). If your
"filename" was something like "" it should open
it just fine, and you can decode incoming frames like normal.

"top posting" is when you quote someone and put your response above
theirs (on top of theirs). Bottom posting (which is what's encouraged
on these mailing lists) is when you quote someone and put your
response below theirs (like Carl and I have done). (Relevant Wikipedia
