GStreamer中，并尝试简单的IM新手wath从Dlink的2103摄像头RTSP流视频。
当我尝试它（只是视频）：
gst-launch rtspsrc location=rtsp://192.168.0.20/live1.sdp ! \
rtph264depay ! \
h264parse ! capsfilter caps="video/x-h264,width=1280,height=800,framerate=(fraction)25/1" !
ffdec_h264 ! ffmpegcolorspace ! autovideosink
没关系。
当我尝试它（只是声音）：
gst-launch rtspsrc location=rtsp://192.168.0.20/live1.sdp ! \
rtpg726depay ! ffdec_g726 ! audioconvert ! audioresample ! autoaudiosink
它也OK。
接下来，我尝试播放音频和视频。 GST推出手册页用于生成这样的事情：
gst-launch-0.10 -m -vvv -e rtspsrc location=rtsp://192.168.0.20/live1.sdp latency=1000 ! \
gstrtpptdemux name=demuxer demuxer. ! \
queue ! \
rtph264depay ! h264parse ! capsfilter caps="video/x-h264,width=1280,height=800,framerate=(fraction)25/1" ! \
ffdec_h264 ! ffmpegcolorspace ! autovideosink demuxer. ! \
queue !
rtpg726depay ! ffdec_g726 ! audioconvert ! audioresample ! autoaudiosink
但视频FREEZ与第一帧。 我也尝试使用decodebin（包括1和2版）这款经典的方式：
gst-launch-0.10 -v souphttpsrc rtspsrc location=rtsp://192.168.0.20/live1.sdp !
decodebin name=decoder decoder. ! queue ! audioconvert ! audioresample !
autoaudiosink decoder. ! \
ffmpegcolorspace ! autovideosink
但它也FREEZ第一框架上。
一种方式我一直在使用它playbin成功...
gst-launch-0.10 playbin2 uri=rtsp://192.168.0.20/live1.sdp
这是我的坏管道或什么问题DLINK相机？ 你能告诉我关键的字，我应该了解更多信息？
提前致谢 ！
溶液1（测试）
好吧，我做了我自己的RTSP服务器来测试
我使用的视频和音频测试索马里红新月会使用以下信息（创建RTSP服务器http://www.ip-sense.com/linuxsense/how-to-develop-a-rtsp-server-in-linux-using-gstreamer/ ）

测试的解码流水线。 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
溶液2（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.`
解码流水线
gst-launch filesrc location=file.ts ! typefind ! mpegtsdemux name=demux demux. ! queue ! h264parse ! ffdec_h264 ! autovideosink demux. ! queue ! mp3parse ! ffdec_mp3 ! audioconvert ! autoaudiosink demux.
溶液3（未测试）
尝试使用Tee为基础的方法。 同时运行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暗示。
有一个共同的来源，以T恤斌 - >叉到这两条管线一个用于音频解码，一个用于视频解码。
SRC - >三通（叉成两个分支-子流水线） - >（分支1将具有音频解复用- >音频解码器- >音频接收器）和（2分支将具有视频解复用- >视频解码器- >视频宿）
给一个镜头（未经测试）以下。 您可能需要调整这条管线一点得到它的工作，但你会得到一个想法。
gst-launch rtspsrc location=rtsp://192.168.0.20/live1.sdp ! queue ! tee name=t !\
rtph264depay t. ! \
h264parse t. ! capsfilter caps="video/x-h264,width=1280,height=800,framerate=(fraction)25/1" t. !
ffdec_h264 t. ! ffmpegcolorspace t. ! autovideosink t. ! queue ! \
rtpg726depay ! ffdec_g726 ! audioconvert ! audioresample ! autoaudiosink
