<p class="MsoNormal"><span lang="EN-US">Hi all,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I’m using the gstreamer
api to play some videos on an embedded system. The playback
is fine, but I get a strange problem when trying to get the
duration and position of the playback. In particular, I
regularly call a function that reads the total duration and
position of the playback, using the lines below<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">len = 0;<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">pos = 0;<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">gst_element_query_duration(pipeline,&fmt,&len);<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">gst_element_query_position
(pipeline, &fmt, &pos);<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">My problem is that when
the playback is finished, the position is greater than the
total duration, for example:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">0:00:46.007844442 /
0:00:45.680000000<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This happens only with
some kind of videos, in particular with mpeg 1 and mpeg 2,
while using h.254/mpeg 4 it seems to work fine. Is this some
kind of bug, or am I missing something?</span></p>

Sounds like a bug. Please file a bug to bugzilla.gnome.org, ideally
link to sample video where it happens.<br>
