RTSP H264 流 MSE 播放

elsampsa/websocket-mse-demo 项目介绍：

It this demo we're streaming live video from an RTSP camera to your HTML5 browser.

Video is streamed as H264 encapsulated in MP4. No transcoding takes place in the stream-to-browser pipeline. No browser-side flash or pure-javascript decoders required.

Video is decoded and presented in the browser using the W3 Media Source Extensions that is well supported by all major browsers by > now.

Only H264 is supported - browser MSE's do not support H246 yet (and neither does libValkka).

实现了浏览器 MSE (Media Source Extensions) 播放相机 RTSP (Real Time Streaming Protocol) 流。动手体验一下咯~

准备

# 系统 Ubuntu 18

# 如有 conda 虚拟环境，请停用
# conda deactivate

# 获取代码
git clone --depth 1 https://github.com/elsampsa/websocket-mse-demo.git

# 安装 libValkka
sudo apt-add-repository ppa:sampsa-riikonen/valkka
sudo apt-get update
sudo apt-get install valkka

# 安装 nginx
sudo apt-get install nginx

# 安装 python websockets
pip3 install websockets

# 准备 nginx 用户权限
sudo addgroup nginx
sudo adduser $USER nginx
sudo chgrp -R nginx /var/lib/nginx /var/log/nginx
sudo chmod -R g+r+w+x /var/lib/nginx /var/log/nginx
# 切换用户组
newgrp nginx
id

# 测试 nginx 工作是否正常（无 Permission denied）
cd websocket-mse-demo
nginx -p $PWD -c ./nginx.conf -g 'error_log error.log warn;'

# 设置相机发送 H264（该项目只支持 H264）

使用

发送 RTSP 流：

sudo snap install vlc
# allow camera permission
snap connect vlc:camera :camera

# 发送 ~/Videos/test.mp4 文件（循环）
#  https://archive.org/download/archive-video-files/test.mp4
vlc file:///$HOME/Videos/test.mp4 --loop \
--sout '#gather:transcode{vcodec=h264}:rtp{sdp=rtsp://:8554/test}' \
--network-caching=1500 --sout-all --sout-keep

# 或，发送 /dev/video0 webcam（实时）
vlc v4l2:///dev/video0:chroma=yuyv:width=640:height=480:fps=30 \
--sout '#transcode{vcodec=h264,width=640,height=480}:rtp{sdp=rtsp://:8554/test}'

# 测试接收 RTSP 流
vlc rtsp://127.0.0.1:8554/test

启动程序：

killall -9 nginx
python3 ws_serve_new.py rtsp://127.0.0.1:8554/test

打开浏览器：

xdg-open http://localhost:8089
