我正在使用以下管道（简化）gstreamer oss构建0.10.7在Win 7 x64上：
udpsrc ! application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96 !
gstrtpjitterbuffer latency=200 ! rtph264depay ! tee name=h264Tee
h264Tee. ! queue ! h264parse ! mux.
matroskamux name=mux ! filesink location=rec.mkv sync=false // same for avimux/mp4/qt
h264Tee. ! queue ! ffdec_h264 ! tee name=videoTee
//.videoTee ! queue ! dx9videosink
//.videoTee ! queue ! appsink
//udpsrc ! queue ! directsoundsink
audiotestsrc ! mux. //only for testing, should be connected to udpsrc
该管道是通过GSTREAMER-SHARP启动的。这是管道的控制台输出：
WARN default xoverlay.c:354:gst_x_overlay_set_xwindow_id:<videoSink> Using deprecated gst_x_overlay_set_xwindow_id()
ERROR d3dvideosink d3dvideosink.c:2204:gst_d3dvideosink_release_swap_chain: Direct3D device has not been initialized
WARN bin gstbin.c:2378:gst_bin_do_latency_func:<pipeline0> failed to query latency
WARN matroskamux matroska-mux.c:970:gst_matroska_mux_video_pad_setcaps:<mux> pad video_0 refused caps 05370C40
，只要我遗漏了Muxer，视频和音频都可以播放。当将Muxer包括在管道中时，视频即时冻结，无法听到声音。怎么了，为什么Muxer拒绝盖子？
好的，我的自我解决了：上面的视频帽不包含Sprop-Caremet-Sets，而播放不需要。对于编码而需要编码，因为这些流的各种特性都在其中编码：
