RTSP (Real Time Streaming Protocol)，实时流协议，是一种应用层协议，专为流媒体运用。本文将介绍 GStreamer, VLC, FFmpeg 这几个东西，怎样发送、接纳 RTSP 流。

条件

  • Ubuntu 18.04 LTS (Bionic Beaver)

GSthttps和http的差异reamer

设备：

sudo apt install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plAPPugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1Git.0-gl gstreameFFmpegr1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio

检查所有插件：

# conda deactivate
gst-inspeapplect-1.0 -a

播放 ~/Vffmpeg教程ideos/test.mp4 文件：

gstgit教程-launch-1.0 filesrc location=~/Videos/tegit教程st.mp4 ! decodebin ! autovideosink

播放 /dev/video0 webcam：

gsthttp://192.168.1.1登录-launch-1.0 v4l2src device=approach/dev/video0 
! video/x-raw, format=ffmpeg安卓版别下载YUY2, width=640, height=480, framerHTTPate=30/1 
! auapprovetovideosinkhttp://www.baidu.com

/dev/video0 相关信息，可见后文“关于 Webcam”。

GStreamer RTSP Server

编译 test-launch 比如：

sudo apt install libgstreamer1.0-dev libgstropencv库tspserver-1.0
git clone https://github.com/GStreamer/gst-rtsp-server.git
cd gstffmpeg装置-rtsp-server/
git checkout 1.ffmpeg安卓版别下载18
cd examples/
gccOpenCV test-launch.c -o test-launch $(pkg-config --cflags --libs gstreamer-rtsp-server-1.0)

用 test-launch 发送 RTSP 检验流：giti轮胎

$ ./test-launch "vidhttpclienteotestsrc ! x264enc ! rtph264pay name=pay0 pt=96"
stream ready at rtsp://127.0.0.1:8554ffmpeg教程/test

用 gst-launch 接纳 RTSP 检验流：

gst-launch-1opencv下载.0 playbin uri=rtsp://127.0.0.1:8554/test

RTSP 流相关东西介绍

发送 RTSP，https和http的差异以 test-launch

发送 ~/Videos/test.mp4 文件:

./test-launch "filesrc location=/home/john/Videos/test.mp4 ! decodebin ! x264enc ! rtph264pay name=pay0 pt=96"

发送 /dev/video0 webcam：

./test-launch "v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=64https和http的差异0,height=480 ! videoconvert ! xhttp://www.baidu.com264enc ! rtph264pay name=ffmpeg指令pay0 pt=96"

接纳 RTSP，以 gst-launch

gst-launch-1.0 playbin uri=rtsp://127.0.0.1:8554/test
# orffmpeg指令
gshttps和http的差异t-launch-1.0 rtspsrc lffmpeg装置ocation=ffmpeg兼并视频rtsp://1ffmpeg指令27.0.0.1:8554/tFFmpegest ! decodebin ! auhttp协议tovideosink

VLCgiti轮胎

设备：

sudo snap install vlc
# allow cameopencv装置教程ra permission
snap connect vlc:camera :camera

检查可用模块：

vlc --list

播放 ~/Videos/test.mp4opencv调用摄像头 文件：

vlc file:///home/john/Videos/test.mp4

播放 /dev/video0 wHTTPebcam：

vlc vhttp代理4l2:///dev/video0:chroma=mjpg:width=640:giti轮胎height=480:fpsffmpeg是什么意思=30

发送 RTSP，以 vlc

FFmpeg

设备：

sudo apOpenCVt install ffmpeg

发送 RTSP，以 ffserver

配备 ffserver.conf：

HTTPPort 8091
HTTPBindAddress 0.0.0.0
RTSPPort 1554
MappleaxHTTPConnections 2000
MaxClffmpeg是什么意思ientsapprove 1000
