<div dir="ltr">Hi All,<div><br></div><div> Actually an android application for playing music I used ffmpeg.I am using the following code for seeking the song in ffmpeg..</div><div><br></div><div>

<p class=""><span class="">then seekbar length will be 200.</span></p><p class=""><span class="">The above code is working for some of the songs..but for some songs If I seek  the song to for ex:3:00 or 2:40 then the song lasts for 3:50(actually duration is 3:20).If I don't seek and play it normally it ends at correct position.So please suggest me in solving this problem.</span></p>
