           Summary: flacdec ! appsink with a seek seems to drop the first
                    buffer
           Product: GStreamer
           Version: git
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

   GNOME milestone: Unspecified


I created a branch where I added a test in tests/check/pipelines/flacdec

The goal is to be able to get a range of decoded samples out of flacdec.  The
range needs to be exact, will be used for CRC'ing.

I attach the log file from running the test_seek_full test, that does a seek
for exactly the complete set of decoded samples.

It looks like gst_pad_alloc_buffer from flacdec on appsink:sink fails because
appsink is flushing.  (I don't know if the seek has to be flushing in this
case, but that's what normally gets done.)
