           Summary: [videorate] fails at upstream negotiation
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal

It looks like videorate doesn't pass on downstream framerate preferences
correctly for upstream negotiation - I suspect it just takes downstream caps
and replaces the framerate field with [0/1; MAX/1] instead of appending the
ANY-FRAMERATE caps to the downstream caps when passing them upstream.


$ gst-launch-0.10 -v videotestsrc num-buffers=1 ! identity ! videorate !
video/x-raw-yuv,framerate=10/1 ! fakesink

videotestsrc0.src: caps = video/x-raw-yuv,framerate=(fraction)30/1, ...
identity0: last-message = "chain   ******* (identity0:sink)i (153600 bytes,
timestamp: 0:00:00.000000000, duration: 0:00:00.033333333"
videorate0.sink: caps = video/x-raw-yuv, framerate=(fraction)10/1, ...
videorate0.src: caps = video/x-raw-yuv, framerate=(fraction)10/1, ...
videorate0.sink: caps = video/x-raw-yuv, framerate=(fraction)30/1, ...
fakesink0.sink: caps = video/x-raw-yuv, framerate=(fraction)10/1, ...
fakesink0: last-message = "chain   ******* < (153600 bytes, timestamp:
0:00:00.000000000, duration: 0:00:00.100000000
