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~


# 系统 Ubuntu 18

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

# 获取代码
git clone --depth 1

# 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

# 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)


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)
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://


killall -9 nginx
python3 rtsp://
