How to save rtsp video stream with correct framerate

[sulli_xue]

Now I know how to save video file with correct framerate,the pipeline is as
follow:"gst-launch-1.0 rtspsrc do-timestamp=true is_live=true
location=rtsp://admin:admin12345@192.168.1.64:554/h264/ch33/main/av_stream
latency=0 ! tee name=t ! queue ! application/x-rtp,
media=video,framerate=25,encoding-name=H264 ! rtph264depay ! h264parse
config-interval=1 ! matroskamux ! filesink location=\"test.mkv\" t. ! queue
! decodebin ! videoconvert ! xvimagesink"
Just replace "mpegtmux" with "matroskamux" can get correct framerate number
25 by cvGetCaptureProperty(capture,CV_CAP_PROP_FPS).However
cvGetCaptureProperty(capture,CV_CAP_PROP_FRAME_COUNT) still get wrong number
and cvSetCaptureProperty(capture,CV_CAP_PROP_POS_FRAMES) cannot goto correct
position.Could someone help me?Please~
