SRS(Simple Realtime Server)

SRS/3.0，OuXuli，是一个流媒体集群，支持RTMP/HLS/FLV，高效、稳定、易用，简单而快乐。
SRS is a RTMP/HLS/FLV streaming cluster, high efficiency, stable and simple.

Remark: Although SRS is licenced under MIT, but there are some depended libraries which are distributed using their own licenses, please read License Mixing.

Usage

Recommend to run SRS by docker:

docker run --rm -p 1935:1935 -p 1985:1985 -p 8080:8080 \
    ossrs/srs:3

# Or, for developers in China to speedup.
docker run --rm -p 1935:1935 -p 1985:1985 -p 8080:8080 \
    registry.cn-hangzhou.aliyuncs.com/ossrs/srs:3

Note: All tags are available, such as ossrs/srs:v3.0-r3 for tag v3.0-r3, please check at here or there.

If it works, open http://localhost:8080/ to check it, then publish stream by:

ffmpeg -re -i doc/source.200kbps.768x320.flv -c copy \
    -f flv rtmp://localhost/live/livestream

# Or by FFmpeg docker
docker run --rm --network=host registry.cn-hangzhou.aliyuncs.com/ossrs/srs:encoder \
  ffmpeg -re -i ./doc/source.200kbps.768x320.flv -c copy \
      -f flv -y rtmp://localhost/live/livestream

Play the following streams by players:

The online demos and players are available on ossrs.net.

Strongly recommend reading bellow wikis:

  • How to deliver RTMP streaming?(CN, EN)
  • How to build RTMP Edge-Cluster?(CN, EN)
  • How to build RTMP Origin-Cluster?(CN, EN)
  • How to deliver HTTP-FLV streaming?(CN, EN)
  • How to deliver HLS streaming?(CN, EN)
  • How to deliver low-latency streaming?(CN, EN)

It's also very easy to build from source:

>>> Step 1: Get SRS.

git clone https://gitee.com/winlinvip/srs.oschina.git srs &&
cd srs/trunk && git remote set-url origin https://github.com/ossrs/srs.git && 
git checkout 3.0release && git pull

Note: We use mirrors(gitee) here, but it's also ok to directly clone by git clone https://github.com/ossrs/srs.git && cd srs/trunk

>>> Step 2: Build SRS.

./configure && make

Remark: Recommend to use Centos7 64bits, please read wiki(CN,EN).

Note: You can also build SRS in docker, please read docker.

>>> Step 3: Run SRS

./objs/srs -c conf/srs.conf

Remark:

  1. Concurrency: We only benchmark the concurrency of single process.
  2. MultipleProcess: SRS supports multiple processes by go-oryx.
  3. HLS aonly: HLS supports audio only mode without video stream.
  4. BW check: The bandwidth check feature is used to detect the bandwidth between server and client.
  5. Security: The security includes access control, token authentication and referer check.
  6. Reload: SRS and Nginx supports reload, but nginx-rtmp doesn't.

Latency benchmark

The latency between encoder and player with realtime config(CN, EN): |

Update SRS VP6 H.264 VP6+MP3 H.264+MP3
2014-12-16 2.0.72 0.1s 0.4s 0.8s 0.6s

2014-12-03 1.0.10 0.4s 0.4s 0.9s 1.2s

2018-08-05, c45f72e, Refine HTTP-FLV latency, support realtime mode. 2.0.252

We used FMLE as encoder for benchmark. The latency of server was 0.1s+, and the bottleneck was the encoder. For more information, read bug #257.

HLS overhead

About the overhead of HLS overhead, we compared FFMPEG and SRS.

Bitrate Duration FLV(KB) HLS(KB) Overhead
275kbps 600s 11144 12756 14.46%
260kbps 1860s 59344 68004 14.59%

565kbps 453s 31316 33544 7.11%
565kbps 1813s 125224 134140 7.12%
861kbps 497s 52316 54924 4.98%
857kbps 1862s 195008 204768 5.00%

5254kbps 71s 45832 47056 2.67%
5147kbps 370s 195040 200280 2.68%
5158kbps 1327s 835664 858092 2.68%

The HLS overhead is calc by: (HLS - FLV) / FLV * 100%.

The overhead should be larger than this benchmark(48kbps audio is best overhead), for we fix the #512.

Architecture

SRS always use the simplest architecture to solve complex domain problems.

  • System arch: the system structure and arch.
  • Modularity arch: the main modularity of SRS.
  • Stream arch: the stream dispatch arch of SRS.
