dvblast和gstreamer

Question

我正在尝试从dvblast (dvb-s)向我的熊猫播放流式视频，但遇到了问题。有人能给我指路吗？

这是我的输出：

gst-launch-0.10 -vm udpsrc port=1234 multicast-group=239.255.0.1 caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,payload=(int)96" ! .recv_rtp_sink_0 gstrtpbin latency=800 ! rtpmp2tdepay ! tsdemux ! ffdec_h264 ! xvimagesink 

Setting pipeline to PAUSED ... ERROR: Pipeline doesn't want to pause.

似乎你在熊猫船上的X-server没有正确设置。在panda上，你能像下面这样运行一个简单的管道吗？

gst-launch videotestsrc ! xvimagesink

你可能想试试"autovideosink“而不是"xvimagesink"，它可以在安装的视频输出中选择”最好的“。
