22.214.171.124 Start Stream
After a 200 HTTP response is received from the server following initialization, the encoder SHOULD initiate a new, long-running HTTP POST request. The payload of the request MUST be the fragment MPEG-4 ([MPEG4-RA]) stream, starting from the header boxes and followed by the fragments. The request MUST follow the specifications in Transport (section 2.1).
If a StreamManifest (section 126.96.36.199) is provided by the encoder, the server waits until all the enumerated streams are received before starting the broadcast. If all the streams are not received within the defined duration time, some of the earlier streams' data MAY be discarded and lost before initialization.
