[Libav-user] output-example.c replacement?

[Gustav González]

That's exactly the point where I started my research. There is interesting
stuff there, but as I mentioned in the first message, all the examples
start assuming an input file.
For example, I want to learn how to set the key parameters of an
AVCodecParameters variable manually, so I can copy it into an
AvContextCodec variable.
The "from scratch" approach is the missing point in the current examples.

PS: The encode_video.c has the potential to introduce several concepts, but
it doesn't use any AVStream component, so it's still incomplete from the
"educational" approach.
