Re: [lwip-users] video transfer using lwIP

[Sergio R. Caprile]

I don't think I follow you completely.
An HTTP server, like the one in lwIP, will let you build your user 
interface. You can send data to the server and you can get data from the 
server. The server can also be instructed to run some code of your own, 
a CGI, when some URLs are requested. Whatever travels inside that "data" 
is up to you.
In this implementation, there is no filesystem per se, but a helping 
construction to serve static content and simple dynamic forms, in the 
form of SSI tags. To serve entirely dynamic content like a video stream, 
you'd be better off using CGIs. To have a full fledged file system, you 
need to run something that provides it, and interface lwIP to that.
When serving, the server will send as much as he can providing the 
content is ready when needed (e.g.: your CGI provides it), as long as 
there is enough buffering space available. Then, the lwIP stack will 
deliver that as best as it can, providing it is accepted by the netif 
driver and the other end can handle that content, as this is TCP. 
Perhaps to send that amount of traffic you'll need to trim your config.
