           Summary: Appsrc & playbin2 reading too much data,
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.23

            Status: UNCONFIRMED

Hi, using version 0.10.23 of the base plugins, I am attempting to use appsrc &
playbin2 to stream some music files.

All works fine until I attempt to seek to a position in the song.

I register my seek-data & need-data callbacks as follows:
g_signal_connect (app->appsrc, "need-data", G_CALLBACK (feed_data), app);
g_signal_connect (app->appsrc, "seek-data", G_CALLBACK (seek_data), app);

I have a seek to time function which makes a call to gst_element_seek as
follows:
gst_element_seek (pipeline, 1.0, GST_FORMAT_TIME,
(GstSeekFlags)GST_SEEK_FLAG_FLUSH, GST_SEEK_TYPE_SET, offset,
GST_SEEK_TYPE_NONE, GST_CLOCK_TIME_NONE)

When I attempt to seek to a position, I see my call to seek-data called with
the correct offset, my feed-data is then called as expected, but, I then see a
massive loop of seek_data & feed_data.

The amount of loops seems related to the position I am seeking to, i.e if I
seek to byte 100 (Illustrative) I seek direct to byte 100 then read a further
100 bytes! If my file is only 150 bytes, I get an EOS and stop.

Is this a bug or am I using these functions incorrectly?
Thanks.
