The ngx_http_flv_module
module provides pseudo-streaming server-side support for Flash Video (FLV) files.
It handles requests with the start
argument in the request URI’s query string specially, by sending back the contents of a file starting from the requested byte offset and with the prepended FLV header.
This module is not built by default, it should be enabled with the --with-http_flv_module
configuration parameter.
