@end example
This protocol accepts the following options:
@table @option
@item blocksize
Set I/O operation maximum block size, in bytes. Default value is
@code{INT_MAX}, which results in not limiting the requested block size.
Setting this value reasonably low improves user termination request reaction
time, which is valuable if data transmission is slow.
@end table
Note that some formats (typically MOV), require the output protocol to
be seekable, so they will fail with the pipe output protocol.
