<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello, I would like to know if there's a way to extract the buffer timestamp<br>
of the video stream that a video player is playing at a certain moment. So<br>
far I've been using the timestamps extracted by an identity element placed<br>
just before the video player but the handoff signals are not generated<br>
synchronously, so between 2 buffers of length = 0.04 s there's a system time<br>
delta extracted at the handoff signal generation slightly different than<br>
0.04 s...for this reason I suppose that either the video player receives<br>
these buffers asynchronously, so it has a buffer itself and synchronizes<br>
with the general clock, or the identity signal is emitted asynchronously (or<br>
maybe both)...<br>
For audio/video synchronization purposes I need to know something like: in a<br>
certain precise instant the video player is displaying a frame with<br>
timestamp=x..is it possible?<br>
Thank you very much.<br>
