I don't know if this is a problem or if I'm missing
something. All I'm trying to do is to <span
style="" class="">transcode</span> audio, from any
format (thanks to <span style="" class="">decodebin</span>
:-) to <span style="" class="">OGG</span>/<span
style="" class="">Vorbis</span>. Just doing this
for an entire file is pretty straightforward and the
example code I'm providing already does that.<br>
<br>
</div>
But when i try to extend it to seek to a specific
position of the audio, and then <span style=""
class="">transcoding</span>, then i get some
problems.<br>
<br>
</div>
When i perform a non-flushing seek... the seek call
hangs forever. If i perform a flushing seek everything
goes "<span style="" class="">ok</span>", but i end up
with a messed up <span style="" class="">OGG</span>
file :-(.<br>
<br>
</div>
When i <span style="" class="">transcode</span> the
entire file:<br>
<br>
./<span style="" class="">ogg</span>-seek-test <audio-<span
style="" class="">src</span>-file><br>
file /<span style="" class="">tmp</span>/test.<span
style="" class="">ogg</span><br>

Any help is deeply appreciated.<br>

There was a bug in oggmux regarding proper flushing when handling a
seek.<br>
<br>
Just got fixed with commit a6890ec7ef69f34b38ae2c600f136b43574102e7
in gst-plugins-base git master.<br>
<br>
Please report if it still doesn't work for you.<br>
