windows - GStreamer 中的 UdpSink 在 Windows 中不工作

Question

我是 GSTreamer 的新手。我尝试使用 GStreamer 上传视频。在运行以下命令时，

gst-launch-1.0 videotestsrc ! udpsink port=5200

我收到如下警告。

WARNING: from element /GstPipeline:pipeline0/GstUDPSink:udpsink0: Attempting to send a UDP packets larger than maximum size (115200 > 65507)
Additional debug info:

GStreamer 参数有什么问题？

这里面有什么遗漏吗？

在通过 UDP 传输视频之前，您需要进行有效负载。

 gst-launch-1.0 videotestsrc ! rtpraw4vpay ! udpsink port=5200

但是通过 udp 传输原始视频并不是首选。传输视频的更好方法是对其进行编码以减小大小。我更喜欢 h264 编码以获得最佳大小。

gst-launch-1.0 videotestsrc ! x264enc ! video/x-h264, stream-format=byte-stream ! rtph264pay ! udpsink port=5200

您将收到此流

gst-launch-1.0 udpsrc port=5200 ! application/x-rtp, encoding-name=H264, payload=96 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink
