Also, if you need more fine grained control over scheduling and synchronization, your plugin should be derived from GstBaseAudioSink rather than GstAudioSink (see section 20.1 of the plugin writer's guide: <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/chapter-other-base.html#section-base-sink">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/chapter-other-base.html#section-base-sink</a>). I'm not familiar enough with OpenAL to know if this is really necessary.<br>
<br>Good luck, this would be a welcome addition to gstreamer.<br><br>-Tristan<br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div link="blue" vlink="purple" lang="EN-US">
<div><p class="MsoNormal"> Regarding
latency_time/buffer_time, I’m leaving them as defaults (they can be modified
thru the properties) and by default I get values of 10,000/0 respectively with
my test. Segsize/segtotal I take as “buffer size” and “number
of buffers”, with OpenAL I have to pre-allocate buffers and while running
I write to the buffer and queue them (and unqueue processed buffers). And so in
my test I get 882 segsize and 20 segtotal so I pre-allocate 20 OpenAL buffers
and fill/queue them during the write() call but what appears to be happening is
that all the buffers gets full before even one buffer gets processed by OpenAL
so I end up overrunning my buffers. Should I be stalling the write() call?
Also, do those values make sense? When I normally stream a sound in OpenAL (not
synced to video) I would allocate fairly large buffers, but not so many (2-3
buffers large enough to keep about 2-3 seconds buffered). But here from
what I understand it’s suggesting I allocate buffers of only a few
samples each (i.e. 882 / 4 = 220 samples).</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">At this point I’m not too worried about latency/delays;
I’m just trying to get something playing sound so that I get a better
feel as to how this interface works.</p>

<p class="MsoNormal">Any input appreciated!</p>
