<DIV>Hello,</DIV>
<DIV></DIV>
<DIV>I'm&nbsp;trying&nbsp;to&nbsp;use&nbsp;the&nbsp;spectrum&nbsp;element&nbsp;for&nbsp;displaying&nbsp;the&nbsp;spectrum&nbsp;in&nbsp;an</DIV>
<DIV>GTK&nbsp;application&nbsp;that&nbsp;uses&nbsp;seeking.&nbsp;Normally,&nbsp;when&nbsp;I&nbsp;connect&nbsp;to&nbsp;the&nbsp;bus</DIV>
<DIV>and&nbsp;listen&nbsp;for&nbsp;the&nbsp;spectrum&nbsp;messages,&nbsp;I&nbsp;get&nbsp;a&nbsp;message&nbsp;once&nbsp;every&nbsp;100ms.</DIV>
<DIV>Now&nbsp;if&nbsp;I&nbsp;seek&nbsp;and&nbsp;set&nbsp;the&nbsp;pipeline&nbsp;to&nbsp;PLAYING,&nbsp;I&nbsp;get&nbsp;the&nbsp;messages&nbsp;for&nbsp;a</DIV>
<DIV>few&nbsp;seconds&nbsp;in&nbsp;advance&nbsp;all&nbsp;at&nbsp;once,&nbsp;then&nbsp;for&nbsp;some&nbsp;time&nbsp;no&nbsp;messages.&nbsp;This</DIV>
<DIV>only&nbsp;happens&nbsp;the&nbsp;second&nbsp;time&nbsp;I&nbsp;seek.</DIV>
<DIV>I&nbsp;programmed&nbsp;a&nbsp;minimal&nbsp;application&nbsp;that&nbsp;shows&nbsp;this&nbsp;behavior:</DIV>
<DIV>http://pastebin.org/463182</DIV>
<DIV>It&nbsp;plays&nbsp;one&nbsp;second&nbsp;of&nbsp;a&nbsp;song,&nbsp;beginning&nbsp;from&nbsp;2.0,&nbsp;using&nbsp;a&nbsp;spectrum</DIV>
<DIV>element,&nbsp;and&nbsp;printing&nbsp;the&nbsp;stream&nbsp;time&nbsp;for&nbsp;each&nbsp;spectrum&nbsp;message.&nbsp;Then&nbsp;it</DIV>
<DIV>repeats&nbsp;this&nbsp;procedure,&nbsp;and&nbsp;this&nbsp;is&nbsp;what&nbsp;I&nbsp;get:</DIV>
<DIV></DIV>
<DIV>2000000000</DIV>

<DIV></DIV>
<DIV>Can&nbsp;anyone&nbsp;explain&nbsp;this&nbsp;behavior?&nbsp;Perhaps&nbsp;I&nbsp;made&nbsp;something&nbsp;fundamentally</DIV>
<DIV>wrong,&nbsp;but&nbsp;how&nbsp;then&nbsp;do&nbsp;I&nbsp;program&nbsp;a&nbsp;graphical&nbsp;spectrum&nbsp;analyzer&nbsp;that</DIV>
<DIV>supports&nbsp;seeking?&nbsp;Am&nbsp;I&nbsp;doing&nbsp;something&nbsp;wrong&nbsp;with&nbsp;the&nbsp;seeking&nbsp;part&nbsp;of</DIV>
<DIV>the&nbsp;program?</DIV>
<DIV></DIV>
<DIV>Thank&nbsp;you&nbsp;very&nbsp;much&nbsp;in&nbsp;advance,</DIV>
