在Windows环境下如何使用GStreamer在同一台计算机上发送和接收RTSP提要
在Windows环境下如何使用GStreamer在同一台计算机上发送和接收RTSP提要
提问于 2020-02-25 04:34:44
我正试图通过网络发送Opencv图像。有人建议我为此使用GStreamer。
我已经安装了GStreamer，现在在我的Windows 10上测试它。
我能够使用以下命令显示测试视频：
gst-launch-1.0 videotestsrc ! videoconvert ! autovideosink现在我试着用RTSP发送视频。现在，我想使用GStreamer流我的桌面，并在VLC中观看它。用于发送我正在使用的视频：
gst-launch-1.0 -v gdiscreencapsrc ! queue ! videoconvert ! video/x-raw,format=I420 ! jpegenc ! rtpjpegpay ! queue ! udpsink host=172.16.15.147 port=8554 对此的答复是：

/GstPipeline:pipeline0/GstRtpJPEGPay:rtpjpegpay0: seqnum = 6294但我无法使用rtsp://172.16.15.147:8554在VLC上观看
我甚至试着把它发送到127.0.0.1:5000
我怎么知道我在发包裹呢？我试着在Wireshark上捕获数据包，但是没有用。
请建议一种在同一台PC上使用GStreamer发送和接收流的方法。

长话短说，您需要一个.sdp文件。
这是SDP文件必须包含的最小值。
v=<version>
c=IN IP4 <IP4 ADDRESS>
m=<media> <udp port> RTP/AVP <payload>
a=rtpmap:<payload> <encoding-name>/<clock-rate>我刚刚在家里的一台相机上测试了一个流，它的参数与您的非常相似，您只需更改IP地址：
v=0
c=IN IP4 192.168.1.188
m=video 5200 RTP/AVP 26
a=rtpmap:26 JPEG/90000那么下面的命令就可以正常工作了
