Camera GStreamer 1.0“；“自动视频接收器”；不打开显示器

使用ubuntu 14.04中安装的默认GStreamer 0.10，我可以捕获我的IP摄像头：

gst-launch-0.10 rtspsrc location=rtsp://admin:123456@192.168.2.254:554/mpeg4cif latency=0 ! decodebin ! ffmpegcolorspace ! autovideosink

它的问题是显示器中的捕获会在一段时间后停止。尽管相机仍在发送rtsp数据包，直到我停止执行（ctrl+c）

我最近安装了gstreamer的最新版本：

sudo add-apt-repository ppa:gstreamer-developers/ppa
sudo apt-get update
sudo apt-get install gstreamer1.0*

为了检查这个新版本是否解决了这个问题，我可以不断地可视化我的IP摄像头的流，以便稍后使用openCV进行处理

我已尝试执行下一个管道：

gst-launch-1.0 rtspsrc location=rtsp://admin:123456@192.168.0.123:554/mpeg4cif ! rtph264depay ! h264parse ! omxh264dec ! videoconvert ! autovideosink sync=false

gst-launch-1.0 rtspsrc location=rtsp://admin:123456@192.168.0.123:554/mpeg4cif ! rtph264depay ! h264parse ! decodebin ! videoconvert ! autovideosink sync=false

gst-launch-1.0 rtspsrc location=rtsp://admin:123456@192.168.0.123:554/mpeg4cif ! rtph264depay ! avdec_h264 ! decodebin ! videoconvert ! autovideosink sync=false

没有人有执行问题，但没有人打开显示器。使用wireshark，我可以看到摄像头发送的数据包与使用gstreamer-0.10时发送的数据包相同，gstreamer-0.10可以正常工作。如果我解决了显示问题，我可以检查这个新版本是否能够连续可视化流，或者它会在一段时间后停止，就像使用gst-0.10一样

有什么建议试试吗？也许是不同的管道

提前谢谢

编辑： 我使用GST_DEBUG=4启动命令，最后一行如下所示：

我不太清楚gstreamer内部是如何工作的，但一切似乎都是正确的
