@ -897,23 +897,32 @@ The required syntax for a TCP url is:
tcp://@var{hostname}:@var{port}[?@var{options}] tcp://@var{hostname}:@var{port}[?@var{options}]
@end example @end example
@table @option @var{options} contains a list of &-separated options of the form
@var{key}=@var{val}.
@item listen The list of supported options follows.
Listen for an incoming connection
@table @option
@item listen=@var{1|0}
Listen for an incoming connection. Default value is 0.
@item timeout=@var{microseconds} @item timeout=@var{microseconds}
In read mode: if no data arrived in more than this time interval, raise error. Set raise error timeout, expressed in microseconds.
In write mode: if socket cannot be written in more than this time interval, raise error.
This also sets timeout on TCP connection establishing.
This option is only relevant in read mode: if no data arrived in more
than this time interval, raise error.
@item listen_timeout=@var{microseconds}
Set listen timeout, expressed in microseconds.
@end table
The following example shows how to setup a listening TCP connection
with @command{ffmpeg}, which is then accessed with @command{ffplay}:
@example @example
ffmpeg -i @var{input} -f @var{format} tcp://@var{hostname}:@var{port}?listen ffmpeg -i @var{input} -f @var{format} tcp://@var{hostname}:@var{port}?listen
ffplay tcp://@var{hostname}:@var{port} ffplay tcp://@var{hostname}:@var{port}
