linux - Gstreamer 文件流到 UDP

Question

我试图从一台电脑流式传输 mp4 文件并使用 Gstreamer 在另一台电脑上打开它

接收者

gst-launch-1.0 -e -v udpsrc port=9002 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, ssrc=(uint)1" ! rtph264depay ! avdec_h264 ! xvimagesink   sync=false

发件人

gst-launch-1.0 -v -e filesrc location=/home/user/Downloads/sample.mp4 ! qtdemux ! h264parse ! rtph264pay pt=96 ssrc=1 ! udpsink host=192.168.88.249 port=9002

现在的问题是什么都没有发生。我没有收到任何错误。当调试信息变为真时，我找不到任何严重错误。

GST_DEBUG=3 只给出一些警告
