These 2 lines are supposed to run synchronously (the files are played in parallel). My problem now is that when one of the file ends (end of seek reached), I need to set a new file (with a new seek). To do this, I set my main pipeline to state READY, then set the new file name and seek in my branch and then set the state back to PLAYING. But doing so, the other subpipeline looses its position and starts over the file it was playing. I tried therefore to set the main pipeline to PAUSED, then only the subpipeline to be changed in READY (then i set its new file), and finally PLAYING again.. But I can't have it working... Is it possible to have different subparts of the main pipeline in different states, or am I just going wrong direction?</DIV> <DIV>Regards,</DIV> <DIV>Al</DIV></DIV></DIV><BR></DIV><BR>-------------------------------------------------------------------------<BR>This SF.Net email is sponsored by the Moblin Your Move Developer's challenge<BR>Build the coolest Linux based applications with Moblin SDK & win great prizes<BR>Grand prize is a trip for two to an Open Source event anywhere in the world<BR><A href="http://moblin-contest.org/redirect.php?banner_id=100&url=/" target=_blank rel=nofollow>http://moblin-contest.org/redirect.php?banner_id=100&url=/</A><BR>_______________________________________________<BR>gstreamer-devel mailing list<BR><A href="mailto:gstreamer-devel@lists.sourceforge.net" target=_blank rel=nofollow ymailto="mailto:gstreamer-devel@lists.sourceforge.net">gstreamer-devel@lists.sourceforge.net</A><BR><A href="https://lists.sourceforge.net/lists/listinfo/gstreamer-devel" target=_blank rel=nofollow>https://lists.sourceforge.net/lists/listinfo/gstreamer-devel</A><BR><BR></BLOCKQUOTE></DIV><BR></DIV></DIV></div><br> </body></html>
