# RTMP publishing and reception

Perfect Streamer works with RTMP and RTMPS as a client: it publishes an SPTS stream to an external ingest point (a video platform ingest or any RTMP receiver) and pulls a stream from an RTMP source on demand. Accepting incoming publications (push ingest, “the way video platforms do it”) is not supported — for such scenarios use a bridge through an external application ([Other inputs and outputs](other_io.md#streamer-other-io)). RTMP is available to SPTS streams only.

## Publishing (output of type rtmp)

The output is added on the stream’s “Outputs” tab (the field names are those of the interface):

**URL (rtmp(s)://…)**
  The address of the ingest point, including the stream key as issued by the receiving platform.
**Bind interface**
  The local interface of the outgoing connection.
**Client timeout**
  The connection timeout, 10 seconds by default.
**Allow HEVC (Enhanced RTMP)**
  HEVC is published through the Enhanced RTMP extension (enabled by default; an additional setting). For receivers without Enhanced RTMP support, turn it off — only H.264 will then be published.
**Verify TLS certificate**
  For RTMPS: verification of the server certificate (disabled by default; an additional setting).

The publishing format is a single program: one H.264 or HEVC video and no more than one AAC audio track. A multi-track source is narrowed down by PID filters at the stream input ([MPEG-TS filtering](spts.md#streamer-spts-filter)); audio tracks in other formats are discarded. If the track layout is incompatible with RTMP, publishing does not take place — the reason is shown in the output statistics ([Stream statistics](../webui/streams.md#webui-stream-stats)).

## Reception (input of type rtmp)

An input of type rtmp pulls a stream from an RTMP source by its URL: the node connects as a client, the received stream is remultiplexed into MPEG-TS and goes through the usual SPTS pipeline ([Processing pipeline](spts.md#streamer-spts-pipeline)). The settings are the same: URL (rtmp(s)://…), Bind interface, Client timeout and Verify TLS certificate for RTMPS.
