This example is showing a more exotic way of using events. The reader should be aware that AVI

files have a limited filesize. Only 4 GB are allowed. We now show what happens when the avimux
|

encoder hits that limit.

- When the internal counter of avimux shows that it is approaching the filesize limit, the

avimux element pushes a buffer containig the footer to the disksink.
