You need to differentiate between a 'feed' and a 'stream'.  Feeds are 
inputs to the server.  Each feed can be converted into multiple 'stream' 
formats that can be output.  All of which are stored in a single ffm 
file.  A feed is 'fed' to ffserver by an instance of ffmpeg.  Each 
'video', which I take to mean a separate feed is stored in a separate 
.ffm file.  All as specified in your .conf file.

Each 'video' requires a separate ffmpeg to 'feed' it to ffserver, and a 
separate ffm file to store it.

Not sure what that means.

yes, do an ffmpeg -i whatever.ffm and it will list the goodies inside. 
Alternatively, connect to the ffserver status page 
(http://whatever.your.server.address.is:8090/stat.html) and see what is 
there.

It would be easier to help if we knew what it was you were trying to 
accomplish and exactly what you have tried (contents of ffserver.conf, 
ffmpeg command line and output, client output etc.)
