           Summary: pipeline containing x264enc stops temporarily if the
                    pipeline seeked to a time before current time
    Classification: Platform
           Product: GStreamer
           Version: 0.10.18
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

I have a pipeline containing x264enc, such as "videotestsrc !
video/x-raw-yuv,width=1024,height=1024,framerate=10/1 ! x264enc ! fakesink
sync=true", when I seek from 90 seconds to 50 seconds the pipeline pauses for
40 seconds (this is true for any timestamps Y > X, seeking from Y to X pauses
for Y-X).  I originally stumbled across this when serving up transcoded video
via RTSP.  It seems to only happen when using x264enc, but perhaps I'm
mistaken.  Also, is this too much to expect of a video encoder?  

I have attached an example.  Entering a number, n, from 0 to 9 and pressing
enter seeks to n * 10 seconds, 'x' exits.  Sorry, it's not terribly
sophisticated.  Thanks.
