解决方案 1(已测试)
好的,我制作了自己的 RTSP 服务器进行测试
我使用以下信息( http://www.ip-sense.com/linuxsense/how-to-develop-a-rtsp-server-in-linux-using-gstreamer/)使用视频和音频测试 src 创建了一个 RTSP 服务器 )

# RTSP demo for Stack Overflow
sample:
gcc -Wall -I/usr/include/gstreamer-0.10 rtsp.c -o rtsp `pkg-config --libs --cflags gstreamer-0.10 gstreamer-rtsp-0.10` -lglib-2.0 -lgstrtspserver-0.10 -lgstreamer-0.10
测试了解码管道。它工作正常!
gst-launch -v rtspsrc location="rtsp://localhost:8554/test" name=demux demux. ! queue ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! autovideosink sync=false demux. ! queue ! rtppcmadepay ! alawdec ! autoaudiosink
解决方案 2(已测试)
尝试使用 mux/demux 组合
`gst-launch-1.0 -e rtspsrc location='rtsp://localhost:554' latency=0 name=d d. ! queue ! capsfilter caps="application/x-rtp,media=video" ! rtph264depay ! mpegtsmux name=mux ! filesink location=file.ts d. ! queue ! capsfilter caps="application/x-rtp,media=audio" ! decodebin ! audioconvert ! audioresample ! lamemp3enc ! mux.`
解码管道
gst-launch filesrc location=file.ts ! typefind ! mpegtsdemux name=demux demux. ! queue ! h264parse ! ffdec_h264 ! autovideosink demux. ! queue ! mp3parse ! ffdec_mp3 ! audioconvert ! autoaudiosink demux.
解决方案 3(未经测试)
尝试使用Tee
基于的方法。还跑gst-launch-0.10 -v playbin2 uri=rtsp://192.168.0.20/live1.sdp
。注意详细选项。这会给你很多关于如何构建管道的提示。
有一个 Tee bin 的公共源 -> 将其分成两条管道,一条用于音频解码,一条用于视频解码。
src -> tee(分叉成两个分支 - 子管道)->(分支 1 将具有音频解复用器 -> 音频解码器 -> 音频接收器)和(分支 2 将具有视频解复用器 -> 视频解码器 -> 视频接收器)
试一试(未经测试)。您可能需要稍微调整此管道才能使其正常工作,但您会有所了解。
