<p>Yes, by default the queue is limited to 200 buffers, 1 MB, or 1
second of data - whichever limit is hit first. You can check the
default values in the docs:
<a class="moz-txt-link-freetext" href="https://gstreamer.freedesktop.org/documentation/coreelements/queue.html?gi-language=c#properties">https://gstreamer.freedesktop.org/documentation/coreelements/queue.html?gi-language=c#properties</a></p>
<p><br>
</p>
<p>So for a 5 second queue, you can set max-size-buffers and
max-size-bytes to zero (no limit) and max-size-time to 5000000000.</p>

<p>You may need to ensure that you have at least 5 seconds of
queue capacity, because the buffers will have to be held
somewhere before they can be processed at the later PTS. I
don't know if this needs to be before the probed pad, or
before the downstream element that cares about the PTS (sink,
muxer, mixer, encoder, ..?)<br>
Kind regards,<br>
Michiel<br>

I tried to add 5 seconds (in ns) to the PTS values on the
incoming buffers in a probe, but I see no delay. I tried it
for both audio and video streams.<br>
<br>
What could be the reason for it not working? I thought PTS
could be used to adjust delay?</div>
