带有GStreamer（RTSP）的流式网络摄像头
我已通过USB电缆连接到Jetson Nano或TX2 我希望能够通过浏览器查看视频，无论是使用RTSP流、Webrtc还是其他方式。 就技术而言，它如何工作并不重要，只要它能工作就行。因此，如果你有任何想法或建议，请随意分享 我目前正在尝试运行基本设置带有GStreamer（RTSP）的流式网络摄像头,gstreamer,rtsp,nvidia-jetson,nvidia-jetson-nano,Gstreamer,Rtsp,Nvidia Jetson,Nvidia Jetson Nano,我已通过USB电缆连接到Jetson Nano或TX2 我希望能够通过浏览器查看视频，无论是使用RTSP流、Webrtc还是其他方式。 就技术而言，它如何工作并不重要，只要它能工作就行。因此，如果你有任何想法或建议，请随意分享 我目前正在尝试运行基本设置 ./test-launch "nvarguscamerasrc ! video/x-raw(memory:NVMM), format=NV12, width=1920, height=1080, framerate=30/1 ! nvvidco

像这样用-v运行管道，并向我显示结果：
gst-launch-1.0 v4l2src device=/dev/video0 ! decodebin ! videoconvert ! videoscale ! videorate ! jpegenc quality=30 ! tcpclientsink host=127.0.0.1 port=8700 -v
如果要流式传输，最简单的方法是使用gst rtsp启动，它是GStreamer预构建二进制文件的一部分：
gst-rtsp-launch '( v4l2src device=/dev/video0 ! videoconvert ! queue ! x264enc tune="zerolatency" byte-stream=true bitrate=10000 ! rtph264pay name=pay0 pt=96 )'
稍后您可以调整编解码器，比特率，但对我来说这已经足够了（可在VLC中播放-rtsp://127.0.0.1:8554/test)``正在将管道设置为暂停。。。管道是带电的，不需要预滚。。。错误：来自元素/GstPipeline:pipeline0/GstV4l2Src:v4l2src0:内部数据流错误。其他调试信息：gstbasesrc.c（3055）：gst_base_src_loop（）：/GstPipeline:pipeline0/GstV4l2Src:v4l2src0:流停止，原因未协商（-4）错误：管道不想预滚。正在将管道设置为暂停。。。正在将管道设置为就绪。。。正在将管道设置为空。。。释放管道```使用-v运行：在管道的末尾添加-v，然后运行它。它在末尾有-v，并返回这个值。我设法用Streamye运行它，但它说jpeg太大了。我使用了这个管道$gst-launch-1.0 v4l2src device=/dev/video1 io mode=2！图像/jpeg，宽度=1280，高度=720，帧速率=30/1！nvjpegdec！视频/x-raw！xImageSink我还发现该解决方案对我不起作用，所以我需要使用gst-rtsp-server。如果你想发送rtp，可以使用这个：gst-launch-1.0 v4l2src device=/dev/video0！实时支付！udpsink端口=2000主机=127.0.0.1。您的src（v4l2src生成jpeg，您不必转换为jpeg）我的视频是4k，3840x2160。当我试着跑的时候，首先我得到：无元素rtmpjpegpay。当我删除该部分时，我得到：警告：从元素/GstPipeline:pipeline0/GstUDPSink:udpsink0：尝试发送大于最大大小的UDP数据包（1554753>65507）其他调试信息：gstmultipudpsink.c（722）：gst_multiudpsink_send_messages（）：/GstPipeline:pipeline0/GstUDPSink:udpsink0：原因：发送消息时出错：消息太长
