我正在尝试使用 gstreamer 在 jetson tx1 和我的电脑之间通过本地网络传输视频。我确保我的相机没有问题，并且我的设备通过本地网络连接。
这是我的终端命令：首先，我使用ssh命令连接到已连接摄像头的 nvidia jetson tx1。然后，在 jetson 上运行以下命令：
sudo gst-launch-1.0 v4l2src device=/dev/video1 ! videorate max-rate=25 ! videoconvert ! omxh265enc qp-range=30,50:30,50:30,50 control-rate=4 bitrate=3000000 ! "video/x-h265, stream-format=(string)byte-stream" ! rtph265pay mtu=1400 ! udpsink host=192.168.1.5 port=5700 sync=false async=false
这是输出：
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Framerate set to : 25 at NvxVideoEncoderSetParameterNvMMLiteOpen : Block : BlockType = 8
===== MSENC =====
NvMMLiteBlockCreate : Block : BlockType = 8
===== NVENC blits (mode: 1) into block linear surfaces =====
然后我就把这个终端窗口挂了。
之后在我的电脑上运行这个：
gst-launch-1.0 udpsrc port=5700 ! application/x-rtp, encoding-name=H265, payload=96 ! rtph265depay ! h265parse ! queue ! avdec_h265 ! fpsdisplaysink sync=false
输出结果如下：
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Redistribute latency...

所以我无法预览直播。我该怎么办？谢谢。
