超好用的跨平台远程视频流传输通道——GStreamer

Gstreamer是一个支持Windows,Linux,Android, iOS的跨平台的多媒体框架,应用程序可以通过管道(Pipeline)的方式,将多媒体处理的各个步骤串联起来,达到预期的效果。每个步骤通过元素(Element)基于GObject对象系统通过插件(plugins)的方式实现,方便了各项功能的扩展。

安装:

sudo apt-get install gstreamer1.0-tools \
  gstreamer1.0-plugins-base \
  gstreamer1.0-plugins-good \
  gstreamer1.0-plugins-bad \
  gstreamer1.0-plugins-ugly

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev

接收:

sudo gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,media=video,payload=26,clock-rate=90000,encoding-name=JPEG,framerate=30/1 ! rtpjpegdepay ! jpegdec ! videoconvert ! autovideosink

发送:


VideoWriter out("appsrc block=false ! queue leaky=downstream ! videoconvert ! video/x-raw,format=YUY2 ! jpegenc ! rtpjpegpay ! udpsink host=... port=...",CAP_GSTREAMER,0,30,
