           Summary: Frames dropped when testing GstSceneChange element
    Classification: Platform
           Product: GStreamer

            Status: UNCONFIRMED
          Severity: normal

Hi all,
    I am new to Gstreamer, so not sure if this is a valid issue

    When i test SceneChange element using
gst-launch-1.0 -v filesrc location=../Wildlife.wmv ! decodebin ! scenechange !
videoconvert ! autovideosink

    the number of frames received via, gst_scene_change_transform_frame_ip,
varies randomly each time for the same video file.
    Does this happen due to lossy decodebin element?

    Since SceneChange element is comparing the previous frame with present
frame to determine if the scene has changed in a video, loss of frame results
in varying results each time.

    is there any fix possible for this? or we should live with it?


Regards,
Vineeth
