This protocol accepts the following options: blocksize Set I/O operation maximum block size, in bytes. Default value is 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. fd Set file descriptor

Note that some formats (typically MOV), require the output protocol to be seekable, so they will fail with the pipe output protocol.
