aviplay

Contacting a live stream, I found it very hard to check if the stream was  
opened, or that it failed.
 From a program face that is. There are two ways to attack this problem

1. Create a new option to exit aviplay on failure
    since I'm no c++ coder, I fail to be able to supply a patch
2. Make the log/error lines line buffered, so they can be monitored  
(followed), and add one extra
    line to report the aviplay process ID, like this:
