ffmpeg gstreamer

Ffmpeg 创建gstreamer管道以发送H264+；MPEG2-TS和RTP上的AC3,ffmpeg,gstreamer,gstreamer-1.0,Ffmpeg,Gstreamer,Gstreamer 1.0,发送器和接收器管道： .\gst-launch-1.0.exe -v mpegtsmux name=mux ! tsparse set-timestamps=true ! rtpmp2tpay ! udpsink host=127.0.0.1 port=8888 videotestsrc is-live=true ! videoconvert ! x264enc ! mux. audiotestsrc is-live=true ! audioresample ! audioconvert

发送器和接收器管道：

.\gst-launch-1.0.exe -v mpegtsmux name=mux ! tsparse set-timestamps=true ! rtpmp2tpay ! udpsink host=127.0.0.1 port=8888   videotestsrc is-live=true ! videoconvert ! x264enc ! mux.   audiotestsrc is-live=true ! audioresample ! audioconvert ! audio/x-raw,rate=44100,channels=2,depth=16 ! avenc_ac3 ! ac3parse ! mux.

我得到一个延迟链接失败的警告，然后我什么也得不到，只有

Type警告

如果我移除接收器的音频支架，它可以正常播放。如果我只播放音频部分，我会得到：

我不确定这有什么不对。退一步说，我真正想要实现的是在OBS中从FFMPEG接收H264+AAC（而不是AC3）。这是行不通的，因为我已经隔离了问题的一部分，这似乎取决于我是如何发送音频的。我现在只在gstreamer中工作，以便在返回FFMPEG土地之前让它在接收端工作
