GStreamer videotestsrc 到 RTP

Question

我只是想让 RTP 示例正常工作，但由于缺少插件或引脚不正确，我看到的每个示例都无法执行。

这似乎是最有希望的，但是，尽管服务器和客户端似乎正确启动并进入“播放”状态，但没有任何 react :

服务器:

gst-launch -v videotestsrc ! \
    video/x-raw-rgb, format=\(fourcc\)RGB, width=4, height=4, frame-rate=1/1 ! rtpvrawpay !
    udpsink host=127.0.0.1 

服务器输出:

/GstPipeline:pipeline0/GstUDPSink:udpsink0.GstPad:sink: caps = application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)RAW, sampling=(string)RGB, depth=(string)8, width=(string)4, height=(string)4, colorimetry=(string)SMPTE240M, payload=(int)96, ssrc=(uint)3779397700, clock-base=(uint)1161131286, seqnum-base=(uint)43390
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...

客户:

gst-launch-0.10 -v udpsrc caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)RAW, sampling=(string)RGB, depth=(string)8, width=(string)4, height=(string)4, colorimetry=(string)SMPTE240M, payload=(int)96, ssrc=(uint)3779397700, clock-base=(uint)1161131286, seqnum-base=(uint)43390" ! rtpvrawdepay ! xvimagesink 

客户端输出:

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...

这些工作:

服务器:

gst-launch-0.10 -v \
gstrtpbin name=rtpbin1 \
videotestsrc ! x264enc ! rtph264pay ! rtpbin1.send_rtp_sink_0 \
rtpbin1.send_rtp_src_0 ! udpsink host=127.0.0.1 port=5011 \
rtpbin1.send_rtcp_src_0 ! udpsink host=127.0.0.1 port=5012 \
udpsrc port=5013 ! rtpbin1.recv_rtcp_sink_0 

客户:

gst-launch-0.10 -v \
