I'm desperate, I have found that the order of commands does not matter, but
if I have come to the conclusion that there are two possibilities.
1 ffmpeg can not do what I need.
2 is missing some command syntax, I purchased a book which says that the order
of commands does not matter that the syntax is correct, I consulted with
adobe and tells me that flash can make streaming using RTMP protocol and
prococolo http, this book only has about streamin with webcam example thus
serves no purpose for me
Does anyone know how I can do to write the header?
