Restarted stream contains legacy frames

[Timtchenko, Michael]

Hi gstreamers,

i'm facing a little problem regarding the stopping/resuming of my camera stream with gstreamer. When I restart the stream by a transition from GST_STATE_PLAYING (1) -> GST_STATE_PAUSING (2) ->GST_STATE_ PLAYING (3), the stream contains the last frames from (1).

Is there a proper way to clear the pipeline? I don't want to see any old frames when I restart my stream.

I've also tried to send flushing events, but without success. I did this by sending the events gst_event_new_flush_start() and gst_event_new_flush_stop().

My pipeline looks like this:

udpsrc port=55555 caps=\"application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96\"
! rtph264depay
! avdec_h264
! decodebin
! videoconvert
! glupload
! appsink

Advice is welcome.

BR
Michael
