我是gstreamer的新手，正在尝试使用VLC媒体播放器上的gstreamer工具播放mp4文件。你们能告诉我这里可能有什么问题
服务器代码：
gst-launch-1.0.exe -v filesrc位置= sample_mp4.mp4！ h264parse！视频/ x-h264！ rtph264pay！ udpsink host = 127.0.0.1 port = 5010
客户代码：
gst-launch-1.0.exe -v udpsrc port = 5010！ application / x-rtp，media =（string）video，payload =（int）96，clock-rate =（int）90000，encoding-name = {string）H264！ rtph264depay！自动视频接收器
VLC SDP文件：
v = 0 m =视频 5010 RTP / AVP 96 c = IN IP4 127.0.0.1 a = rtpmap：96 H264-ES / 90000
服务器端的输出：
