我怎样才能进行原始发送和原始接收？这不起作用，我无法播放我发送的内容：

Send: $ gst-launch -v autoaudiosrc ! udpsink host=127.0.0.1 auto-multicast=true port=4444

Recv/play:
[root@example ~]# gst-launch udpsrc multicast-group=127.0.0.1 port=4444 ! autoaudiosink

您需要为源指定功能。这才是真正的ERROR: from element /GstPipeline:pipeline0/GstAudioConvert:audioconvert0: not negotiated意思。（在 gst-launch 上使用-v标志以查看有关错误的更多详细信息）。

所以，解决方案是：

$ gst-launch -v udpsrc multicast-group=127.0.0.1 port=4444 \
    ! audio/x-raw-int, endianness=1234, signed=true, width=16, depth=16, rate=44100, channels=2 \
    ! autoaudiosink

实际上，我只是从发送 gst-launch 的详细输出中复制了功能。
