我需要播放RTP电视流的帮助，我的实际管道无法返回任何图像。我尝试了很多在这里和互联网上找到的示例，但没有成功。
我希望有人能帮助我，这是我的做法错误。
gst-launch-1.0 -v udpsrc buffer-size="5000" port=10000 multicast-group="239.186.68.1" caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264" ! rtph264depay ! avdec_h264 ! autovideosink
ffprobe的输出：
