Not suitable for ultra-low latency.</td> </tr> </tbody> </table> <p>RTMP is a widely-used protocol for video streaming that YouTube Live has accepted since the service began.</p> <p>RTMPS is a secure extension to RTMP. RTMPS benefits both content creators and viewers by preventing man-in-the-middle attacks on the ingestion side of livestreams. This ensures that all of a creator's live streaming data — including video, audio, and control signals — is securely transmitted to YouTube's servers, protecting it from tampering or interception in transit.</p> <p>The HLS and DASH ingestion protocols are also encrypted, like RTMPS. They also support codecs that RTMP and RTMPS do not. Next-generation video codecs such as VP9 and HEVC can offer much better compression relative to H.264, allowing users to either stream with higher quality for a given bitrate or stream with the same quality while using a lower bitrate, which could decrease buffering. This makes HLS or DASH ingestion a good choice for premium content that requires higher quality and higher resolution, albeit at a relatively higher latency. Note that HLS and DASH ingestion typically incur greater latency than RTMP because HLS and DASH are segment-based.</p> </div> <devsite-recommendations display="in-page" hidden yield> </devsite-recommendations> <devsite-thumb-rating position="footer"> </devsite-thumb-rating> <devsite-recommendations id="recommendations-link" yield></devsite-recommendations> </article> <devsite-content-footer class="nocontent"> <p>Except as otherwise noted, the content of this page is licensed under the <a href="https://web.archive.org/web/20211126013829/https://creativecommons.org/licenses/by/4.0/">Creative Commons Attribution 4.0 License</a>, and code samples are licensed under the <a href="https://web.archive.org/web/20211126013829/https://www.apache.org/licenses/LICENSE-2.0">Apache 2.0 License</a>.
