Question

我有一个来自HW编码器的RTP流，我想使用Gstreamer 0.10向RTSP客户端提供服务。使用＆＃34; test-video.c＆＃34;作为一个起点我能够为videotestsrc提供服务，但是没有任何运气服务于传入的RTP流。我按如下方式修改了管道。

gst_rtsp_media_factory_set_launch (factory, "(gstrtpbin name=rtpbin latency=200 udpsrc caps=\"application/x-rtp, media=video, clock-rate=90000, encoding-name=MP2T-ES, payload=33\" port=5000 ! rtpbin.recv_rtp_sink_0 rtpbin. ! queue name=pay0 "

但它不起作用。我猜它与没有正确携带的帽子有关。

尝试播放时，我在服务器上收到以下消息

＆＃34;内部数据流问题＆＃34;不是一个有希望的迹象。输入流是MPEG2传输流内的H.264视频。关于如何解决这个问题的任何想法？

谢谢，

您可能需要一个mpegtsdemux元素（在gstreamer坏插件中）来解复用MPEG2TS的视频流。

使用GStreamer通过RTSP提供RTP流
