If set to 1 enables experimental HTTP server. If set to 1 enables experimental HTTP server. This can be used to send data when
used as an output option, or read data from a client with HTTP POST when used as
an input option.
@example
# Server side (sending):
ffmpeg -i somefile.ogg -c copy -listen 1 -f ogg http://@var{server}:@var{port}
# Client side (receiving):
ffmpeg -i http://@var{server}:@var{port} -c copy somefile.ogg
# Client can also be done with wget:
wget http://@var{server}:@var{port} -O somefile.ogg
# Server side (receiving):
ffmpeg -listen 1 -i http://@var{server}:@var{port} -c copy somefile.ogg
# Client side (sending):
ffmpeg -i somefile.ogg -chunked_post 0 -c copy -f ogg http://@var{server}:@var{port}
# Client can also be done with wget:
wget --post-file=somefile.ogg http://@var{server}:@var{port}
