GStreamer开发笔记（九）：gst-rtcp-server安装和部署实现简单的rtsp-server服务器推流Demo

前言

  Gstreamer还有一个重要的功能就是充当rtsp流媒体服务器。

 

注意

  本ubuntu是虚拟机，对延迟可能影响较大，延迟可作为参考，物理机可能更快。

 

Demo

  

 

RTP和RTSP支持

  GStreamer对RTP和RTSP都有很好的支持，其RTP/RTSP栈多年来已被广泛应用于各种关键任务和低延迟场景的生产中，从小型嵌入式设备到大型视频会议和指挥控制系统。

安装gst和gst-rtsp-server

安装gstreamer1.0环境

sudo apt-get update
sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio
sudo apt-get install libglib2.0-0

查看本地gst版本

  

下载对应版本GStreamer-rtsp-server

  下载地址：https://gstreamer.freedesktop.org/src/gst-rtsp-server/
  

 

Ubuntu编译gstreamer-rtsp-server

步骤一：下载解压

cd ~/work/src
tar xvf gst-rtsp-server-1.16.3.tar.xz

  

步骤二：配置

cd gst-rtsp-server-1.16.3/
./autogen.sh

  

步骤三：出现配置错误“gtk-doc >= 1…12”

  

sudo apt-get install gtk-doc-tools

  继续：

./autogen.sh

  完成：
  

步骤四：编译

make -j4
make

  

  

步骤五：安装部署

sudo make install

  

  

步骤六：测试gst-rtsp-server

./test-launch "( v4l2src device=/dev/video0 ! video/x-raw, format=NV12, width=1920, height=1080, framerate=30/1 ! mpph264enc ! rtph264pay name=pay0 pt=96 )"

  

./test-launch “( videotestsrc ! video/x-raw,width=640,height=480,framerate=30/1 ! timeoverlay ! tee name=vsrc vsrc. ! queue ! videoconvert ! ximagesink vsrc. ! queue ! x264enc tune=zerolatency ! rtph264pay name=pay0 pt=96 )”

  

  

  关掉防火墙重启，再次连接：
  

  检查摄像头支持的格式：
  

  推送测试视频流：

./test-launch "( videotestsrc ! x264enc ! rtph264pay name=pay0 pt=96 )"

  

  继续测试摄像头，增加调试宏：
  

  

  整理如下：
  

  将：

./test-launch "( v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480,framerate=30/1 ! queue ! x264enc ! rtph264pay name=pay0 pt=96 )"

  改为：

./test-launch "(  v4l2src device=/dev/video0 ! video/x-raw, format='YUY2', width=640, height=480, framerate=30/1  ! queue ! x264enc ! rtph264pay name=pay0 pt=96 )"

  继续，报错：
  

  修改：

GST_DEBUG=1 ./test-launch "( v4l2src device=/dev/video0 ! video/x-raw, format=YUY2, width=640, height=480, framerate=30/1  ! queue ! x264enc ! rtph264pay name=pay0 pt=96 )"

  继续：
  

  修改：

./test-launch "( v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! queue ! videoconvert ! x264enc ! rtph264pay name=pay0 pt=96 )"

  继续，播放了，延迟4-5s左右：
  

  优化参数：

./test-launch "( v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! queue ! videoconvert ! x264enc tune=zerolatency speed-preset=ultrafast ! rtph264pay name=pay0 pt=96 )"

  继续，延迟还有1.4s左右：
  

  继续优化：

./test-launch "( v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! queue max-size-buffers=1 max-size-bytes=0 max-size-time=0 ! videoconvert ! x264enc tune=zerolatency speed-preset=ultrafast ! rtph264pay name=pay0 pt=96 )"

  还是1.4s左右：
  

步骤七：使用image/jepg格式

./test-launch "( v4l2src device=/dev/video0 ! image/jpeg,width=640,height=480,framerate=30/1 ! queue max-size-buffers=1 max-size-bytes=0 max-size-time=0 ! videoconvert ! x264enc tune=zerolatency speed-preset=ultrafast ! rtph264pay name=pay0 pt=96 )"

  

  修改为：

GST_DEBUG=1 ./test-launch "( v4l2src device=/dev/video0 ! image/jpeg,width=640,height=480,framerate=30/1 ! queue max-size-buffers=1 max-size-bytes=0 max-size-time=0 ! jpegdec ! videoconvert ! x264enc tune=zerolatency speed-preset=ultrafast ! rtph264pay name=pay0 pt=96 )"

  

 

与live555直接在getNextFramed对比

  

   

  此方法需要2秒多，且用的是mpeg。
