One 、 background

​ Studying recently ffmpeg Basic operation ,ffmpeg Very powerful , Can run Audio And video in multiple formats 、 transformation 、 Stream function , Contains libavcodec—— This is a decoder library for audio and video in multiple projects , as well as libavformat—— An audio and video format conversion library

You can use ffmpeg Splice media files , transformation , Recording , Screenshot , Push the flow and so on , This time, we use ffmpeg Push the local video file to the streaming media server, and then html The operation of streaming and playing , The required configuration and preparation are as follows .

Ffmpeg	Streaming tools
EasyDarwin	Streaming services
Centos7	The server

Two 、 install EasyDarwin

EasyDarwin Is a high-performance open source RTSP Streaming media server , be based on go Language development , Maintenance and optimization RTSP Push mode forwarding 、RTSP Pull mode forwarding 、 videotape 、 retrieval 、 The playback 、 Keyframe cache 、 Second on screen 、RESTful Interface 、WEB Background management 、 Distributed load balancing ！

Media services in easydarwin Download and install the version that conforms to the server from the official website of

wget https://github.com/EasyDarwin/EasyDarwin/releases/download/v8.1.0/EasyDarwin-linux-8.1.0-1901141151.tar.gz
tar -zvxf EasyDarwin-linux-8.1.0-1901141151.tar.gz
cd EasyDarwin-linux-8.1.0-1901141151/

After entering the installation directory, there is a easydarwin.ini file   You need to configure the service account and port .

[http]
port=3000
default_username=admin
default_password=admin

[rtsp]
port=2379

; rtsp  Timeout time , Include RTSP Establish connection and send and receive data .
timeout=28800

;  Whether to enable gop cache. If enabled , The server caches the last I Frame and subsequent non I frame , To increase playback speed . But it may cause memory pressure in the case of high concurrency .
gop_cache_enable=1

;  Whether the user name and password can be verified when streaming to the server or playing from the server . [ Be careful ]  Because the server does not store plaintext passwords , So when pushing or playing , The client should enter the password md5 After the value of .
; password should be the hex of md5(original password)
authorization_enable=0

;  Whether to enable pushed colleagues to store locally , After enabling, video query and playback can be performed .
save_stream_to_local=0

;easydarwin Use ffmpeg Tools to store . It means ffmpeg The path of the executable program 
ffmpeg_path=/Users/ze/Downloads/ffmpeg-20180719-9cb3d8f-macos64-shared/bin/ffmpeg

; Local store the root directory to be saved . If it doesn't exist , The program will try to create the directory .
m3u8_dir_path=/Users/ze/Downloads/EasyDarwinGoM3u8

; Slice file duration . When storing locally , This time period will be used as the standard to generate ts file ( The time + One I Frame spacing ), Unit second .
; If you need live broadcast , Let this value be smaller , But this will produce a lot ts file ; If you don't need live broadcast , As long as it is stored , It can be set larger .
ts_duration_second=6

;key It is the user-defined path for pulling flow ,value by ffmpeg Transcoding format , For example, it can be set to -c:v copy -c:a copy, Express copy The source format ;default Said the use of ffmpeg Built in output format , Will transcode .
/stream_265=default

about rtsp Streaming testing and use only need to pay attention to http Port number and account of the service part ,rtsp Partial port configuration . When configuring , Note that the server port is open .

Run directly under the installation directory .start.sh The script can start  EasyDarwin service , because EasyDarwin Yes, it is golang To write , Therefore, the server configuration is required golang Installation environment .

  Open after startup open in browser The server ip: port

You can't see any information before streaming .

//  Push local media files 
ffmpeg.exe -re -stream_loop -1 -i 1out.mp4 -vcodec h264 -f rtsp rtsp://49.232.162.xxx:2379/test
//  Video recording and streaming 
ffmpeg -f gdigrab -i desktop  -r 15 -vf scale=640:360 -rtsp_transport tcp -vcodec h264 -f rtsp rtsp://localhost/capture
//  Recording screen 
ffmpeg -f gdigrab -i desktop -f mp4 out.mp4

  Use this command to set the local 1out.mp4 Push video to the streaming server , Note that the format used this time is rtsp, Of course you can specify other formats , Note that the push address port is the specified open port of the media service .

When the streaming is successful, it will be in EasyDarwin The corresponding streaming record can be seen at the service address of .

  Four 、 Pull flow operation

After successfully pushing the flow, you can pull the flow , Copy the playback address in the streaming list , After copying, you can use VLC The tool plays

When the playback is normal, in  EasyDarwin The corresponding pull records can be seen in the pull list of the service

  This completes the function of pushing the local stream to the remote streaming service and playing the stream .
