Open [http://localhost:8080/](http://localhost:8080/) to check it, then publish [stream](https://github.com/ossrs/srs/blob/3.0release/trunk/doc/source.200kbps.768x320.flv) by: ```bash docker run --rm --network=host ossrs/srs:encoder ffmpeg -re -i ./doc/source.200kbps.768x320.flv \ -c copy -f flv -y rtmp://localhost/live/livestream ``` > Note: If WebRTC enabled, you can publish by [H5](http://localhost:8080/players/rtc_publisher.html?autostart=true). Play the following streams by [players](https://ossrs.net): * VLC(RTMP): rtmp://localhost/live/livestream * H5(HTTP-FLV): [http://localhost:8080/live/livestream.flv](http://localhost:8080/players/srs_player.html?autostart=true&stream=livestream.flv&port=8080&schema=http) * H5(HLS): [http://localhost:8080/live/livestream.m3u8](http://localhost:8080/players/srs_player.html?autostart=true&stream=livestream.m3u8&port=8080&schema=http) * H5(WebRTC): [webrtc://localhost/live/livestream](http://localhost:8080/players/rtc_player.html?autostart=true) It's also very easy to build from source: ``` git clone -b develop https://gitee.com/winlinvip/srs.oschina.git srs && cd srs/trunk && git remote set-url origin https://github.com/ossrs/srs.git && ./configure && make && ./objs/srs -c conf/srs.conf ``` > Note: We use [mirrors(gitee)](#mirrors) here, but it's also ok to `git clone https://github.com/ossrs/srs.git` > Remark: Recommend to use Centos7 64bits, please read wiki([CN][v4_CN_Build],[EN][v4_EN_Build]), or use [docker][docker-dev].

Security: The security includes access control, token authentication and referer check. 1. Reload: SRS and Nginx supports reload, but nginx-rtmp doesn't. ## Performance The performance benchmark data and corelative commits are listed here. * See also: [Performance for x86/x64 Test Guide][v4_CN_Performance]. * See also: [Performance for RaspberryPi][v4_CN_RaspberryPi]. * For multiple processes performance, read [#775: REUSEPORT][bug #775] or OriginCluster([CN][v4_EN_OriginCluster]/[EN][v4_EN_OriginCluster]) or [go-oryx][oryx]. * For RTC benchmark, please use [srs-bench](https://github.com/ossrs/srs-bench/tree/feature/rtc#usage). **Play RTMP benchmark** The data for playing RTMP was benchmarked by [SB][srs-bench]: | Update | SRS | Clients | Type | CPU | Memory | Commit | | ------------- | --------- | ------------- | ------------- | --------- | -------- | ------------ | | 2014-12-07 | 2.0.67 | 10k(10000) | players | 95% | 656MB | [code][p12] | | 2014-12-05 | 2.0.57 | 9.0k(9000) | players | 90% | 468MB | [code][p11] | | 2014-12-05 | 2.0.55 | 8.0k(8000) | players | 89% | 360MB | [code][p10] | | 2014-11-22 | 2.0.30 | 7.5k(7500) | players | 87% | 320MB | [code][p9] | | 2014-11-13 | 2.0.15 | 6.0k(6000) | players | 82% | 203MB | [code][p8] | | 2014-11-12 | 2.0.14 | 3.5k(3500) | players | 95% | 78MB | [code][p7] | | 2014-11-12 | 2.0.14 | 2.7k(2700) | players | 69% | 59MB | - | | 2014-11-11 | 2.0.12 | 2.7k(2700) | players | 85% | 66MB | - | | 2014-11-11 | 1.0.5 | 2.7k(2700) | players | 85% | 66MB | - | | 2014-07-12 | 0.9.156 | 2.7k(2700) | players | 89% | 61MB | [code][p6] | | 2014-07-12 | 0.9.156 | 1.8k(1800) | players | 68% | 38MB | - | | 2013-11-28 | 0.5.0 | 1.8k(1800) | players | 90% | 41M | - | **Publish RTMP benchmark** The data for publishing RTMP was benchmarked by [SB][srs-bench]: | Update | SRS | Clients | Type | CPU | Memory | Commit | | ------------- | --------- | ------------- | ------------- | --------- | -------- | ------------ | | 2014-12-04 | 2.0.52 | 4.0k(4000) | publishers | 80% | 331MB | [code][p5] | | 2014-12-04 | 2.0.51 | 2.5k(2500) | publishers | 91% | 259MB | [code][p4] | | 2014-12-04 | 2.0.49 | 2.5k(2500) | publishers | 95% | 404MB | [code][p3] | | 2014-12-04 | 2.0.49 | 1.4k(1400) | publishers | 68% | 144MB | - | | 2014-12-03 | 2.0.48 | 1.4k(1400) | publishers | 95% | 140MB | [code][p2] | | 2014-12-03 | 2.0.47 | 1.4k(1400) | publishers | 95% | 140MB | - | | 2014-12-03 | 2.0.47 | 1.2k(1200) | publishers | 84% | 76MB | [code][p1] | | 2014-12-03 | 2.0.12 | 1.2k(1200) | publishers | 96% | 43MB | - | | 2014-12-03 | 1.0.10 | 1.2k(1200) | publishers | 96% | 43MB | - | **Play HTTP FLV benchmark** The data for playing HTTP FLV was benchmarked by [SB][srs-bench]: | Update | SRS | Clients | Type | CPU | Memory | Commit | | ------------- | --------- | ------------- | ------------- | --------- | -------- | ------------ | | 2014-05-25 | 2.0.171 | 6.0k(6000) | players | 84% | 297MB | [code][p20] | | 2014-05-24 | 2.0.170 | 3.0k(3000) | players | 89% | 96MB | [code][p19] | | 2014-05-24 | 2.0.169 | 3.0k(3000) | players | 94% | 188MB | [code][p18] | | 2014-05-24 | 2.0.168 | 2.3k(2300) | players | 92% | 276MB | [code][p17] | | 2014-05-24 | 2.0.167 | 1.0k(1000) | players | 82% | 86MB | - | **RTC benchmark** The RTC benchmark data, by [srs-bench](https://github.com/ossrs/srs-bench/tree/feature/rtc#usage): | Update | SRS | Clients | Type | CPU | Memory | Threads | | ------------- | --------- | ------------- | ------------- | --------- | -------- | ------- | | 2021-03-31 | 4.0.87 | 550 | publishers | ~86% | 1.3GB | 1 | | 2021-03-31 | 4.0.87 | 800 | players | ~94% | 444MB | 1 | > Note: CentOS7, 500Kbps, 4CPU, 2.5 GHz Intel Xeon Platinum 8163/8269CY. **Latency benchmark** The latency between encoder and player with realtime config([CN][v4_CN_LowLatency], [EN][v4_EN_LowLatency]): | | Update | SRS | VP6 | H.264 | VP6+MP3 | H.264+MP3 | | ------------- | --------- | --------- | --------- | --------- | -------- | | 2014-12-16 | 2.0.72 | 0.1s | 0.4s |[0.8s][p15]|[0.6s][p16]| | 2014-12-12 | 2.0.70 |[0.1s][p13]|[0.4s][p14]| 1.0s | 0.9s | | 2014-12-03 | 1.0.10 | 0.4s | 0.4s | 0.9s | 1.2s | > 2018-08-05, [c45f72e](https://github.com/ossrs/srs/commit/c45f72ef7bac9c7cf85b9125fc9e3aafd53f396f), Refine HTTP-FLV latency, support realtime mode. 2.0.252 We used FMLE as encoder for benchmark.
