type: "file" # string: "file", "embedding", "zmq"
address: "video.mp4" # string: url or path, depending on 'type' property
filter:  # array of integers: source(s) to filter on (by zero-based index), no filter if list is empty
addressis a url to either a zmq socket, video file or directory.
filterfiltering can be performed on the input
sourceby specifying a list of integers of the
sourceyou want to filter on. In configuration files
sourcesare implicitly indexed top-to-bottom starting from index 0. An empty list indicates that no filtering should be performed.

file: stream out to file.
zmq: publish output stream on a ZMQ socket.
embedding: creates and embedding database for further annotation by the user.
