<div>Hi ,</div> <div> </div> <div>Yes that's true that in PAUSE state itself sink element will have a buffer and this shows that pipeline is no more waiting for anything ( resources etc) , everything goes fine till this point and pipeline is ready to play. </div> <div class="gmail_quote">On Tue, Jun 15, 2010 at 1:27 AM, Rad E. <<a href="mailto:rad_e@rocketmail.com">rad_e@rocketmail.com</a>> wrote: <blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote"> <table border="0" cellspacing="0" cellpadding="0"> <tbody> <tr> <td valign="top"> Hi, I'm running a pipeline fed by rtspsrc. The pipeline incorporates a GstTee/queues. Something like: rtspsrc -> ... -> tee -> queue -> element -> sink -> queue -> element -> sink The rtspsrc documention suggests that it is a live source: "rtspsrc acts like a live source and will therefore only generate data in the PLAYING state." An element downstream of the rtspsrc/tee/queue is receiving frames in the PAUSED state, immediately before the element is set to the PLAYING state. Is this normal, or is something incorrect with my pipeline that I should investigate further? Receiving the frames in the PAUSED state presents a problem. I would like to convert each buffer's pipeline timestamp to a system timestamp. So for instance if the frame was timestamped 0.25 seconds ago by rtspsrc, I'd like to generate a wall clock/system time of current time - 0.25 seconds. We achieved this using the element base src time, but that time isn't available in PAUSED state. I received a recommendation from IRC to use gst_element_query_position, but looking at the docs its not clear to me how to use that to make this work. Does anyone have ideas, either a way to work around the frames arriving in PAUSED, or a different way to calculate time?
