Description Sebastien Cote 2005-11-15 15:11:03 UTC 
Run the following pipeline:
   gst-launch-0.9 fakesrc num-buffers=1 ! video/x-raw-yuv ! fakesink
   
      (gst-launch-0.9:18474): GStreamer-CRITICAL **: gst_caps_ref: assertion
`caps != NULL' failed
      (gst-launch-0.9:18474): GStreamer-CRITICAL **: gst_caps_unref: assertion
`caps != NULL' failed

The assertions are triggered by the GstBaseTransform class (from which
capsfilter inherits) which refs and unrefs the caps from the source pad in
gst_base_transform_prepare_output_buf(). These caps are not set until the first
buffer has passed through.

        * gst/base/gstbasetransform.c:
        (gst_base_transform_prepare_output_buf),
        (gst_base_transform_event):
        Check if the caps are NULL, this can happen if the element
        is shutting down and the pad caps are set to NULL.
