Note that the "reuseFirstSource" variable should be set to True only 
if you want to open the input source object only once, even if 
multiple clients are simultaeously accessing the stream.  I.e., you 
usually set it to True only if your input source is a live stream 
(e.g., from a video camera), because in this case, you want each 
client to be fed from the single input source.

However, if you are streaming 'video on demand' - e.g., from files - 
where you want each client to get its own copy of the input (starting 
from the beginning), then you should set "reuseFirstSource" to False.

Even if you are streaming the *same* file to multiple clients, then 
you should set "reuseFirstSource" to False, because in this case you 
still want each client's stream to start from the beginning of the 
file (i.e., you want the input file to be opened separately for each 
client).
