this seek error is confusing and appears to be wrong

[Andres Gonzalez]

Hi,

I have a simple pipeline:  filesrc -> decodebin ....... appsink

I am testing with several of the big buck bunny files which all appear to be
correctly formatted container files when playing them with various media
players and as verified by gst-discoverer. The pipeline works without errors
when played normally.

I first put the pipeline in the PAUSED state, then after several seconds I
issue this seek command:

    gst_element_seek(pGstPipeline, 1.0, GST_FORMAT_TIME,
GST_SEEK_FLAG_FLUSH,
                            GST_SEEK_TYPE_SET, lNewPosition,
GST_SEEK_TYPE_NONE, GST_CLOCK_TIME_NONE)

this fails and produces the following information.  This is my logging
output which contains some logging from my routines and the bus messages.
The onFileEOS() is the signal handler from the final appsink.

stream duration                                 : 0:09:56.461666666

The confusing part is the invalid file error because the files are indeed
correct. Also, after this error the pipeline goes to the PAUSED state with
the stream position of 0:00:00.000000000.

Question: why do I get the invalid file error?
Question: why is the appsink posting 2 EOS events?
Question: why is the stream position 0:00:00.000000000 after the EOS event? 
should it not be the end of the file or the duration of 0:04:58.230833333?

Thanks,
-Andres
