1. RTSP协议建立服务器(该代码是C,但看看我的客户端端代码,看看它如何的API是相当直截了当) 我修改了代码的URL

Makefile文件

# Copyright (c) 2012 enthusiasticgeek
# RTSP demo for Stack Overflow
sample:
gcc -Wall -I/usr/include/gstreamer-0.10 rtsp.c -o rtsp `pkg-config --libs --cflags gstreamer-0.10 gstreamer-rtsp-0.10` -lglib-2.0 -lgstrtspserver-0.10 -lgstreamer-0.10

一旦你建立了二进制,简单来说它./rtsp然后打开另一个选项卡中的终端测试以下的pipeline。 测试解码流水线。它工作得很好!

gst-launch -v rtspsrc location=" CodeGo.net  name=demux demux. ! queue ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! autovideosink sync=false demux. ! queue ! rtppcmadepay ! alawdec ! autoaudiosink

 gst_rtsp_media_factory_set_launch (factory,
      "( videotestsrc is-live=1 ! x264enc ! rtph264pay name=pay0 pt=96 )");
