Apologies for top posting, it's my very first time using a mailing list.

If you are talking about the "muxing.c" example under doc, yes I have looked
at it and attempted to implement similar format in my code. However as I
stated before, I get the "identifier not found" error at compiling time. I
have included opt.h and avcodec.h avformat.h at the top of my code, so I'm
just wondering if there are anything else I need to include.

P.S. when I right click on the function and "jump to definition", it
actually jumps to the function deceleration in opt.h.
