The following benchmark data shows end-to-end latency tested using the srs-bench tool with SRS running in real-time configuration(CN, EN):
| Update | SRS | Protocol | VP6 | H.264 | VP6+MP3 | H.264+MP3 |
|---|---|---|---|---|---|---|
| 2014-12-16 | 2.0.72 | RTMP | 0.1s | 0.4s | [0.8s][p15] | [0.6s][p16] |
| 2014-12-12 | 2.0.70 | RTMP | [0.1s][p13] | [0.4s][p14] | 1.0s | 0.9s |
| 2014-12-03 | 1.0.10 | RTMP | 0.4s | 0.4s | 0.9s | 1.2s |
| 2021-04-02 | 4.0.87 | WebRTC | x | 80ms | x | x |
2018-08-05, c45f72e, Refine HTTP-FLV latency, support realtime mode. 2.0.252
Note: Multiple factors can impact end-to-end latency, such as the encoder, server, protocol, player, and network.
Note: VLC player is not recommended for low latency use scenarios due to its large buffer, resulting in significant latency.
