通过在gst-rtsp-server examples目录的test-video.c文件中调用这些函数，我找到了将videotestsrc元素流式传输到Internet的方法：
gst_rtsp_server_set_address(server,"10.xxx.xx.xxx");
gst_rtsp_server_set_service(server,"8555");
并解锁aws控制台中的端口。
但现在用test-video.c中的以下内容替换videotestsrc，如下所示：
gst_rtsp_media_factory_set_launch (factory, "( "
"filesrc location=/home/ubuntu/DELTA.mpg ! mpeg2dec ! x264enc ! rtph264pay name=pay0 pt=96 "
")");
我无法在vlc播放器上看到流。
尝试以下命令会产生以下输出：

我在这里做错了什么？
