So... it's not possible with realtime priority when using gst-launch today? Is that the conclusion?<div>/Mathias<br><br><div class="gmail_quote">2011/2/22 Mathias Gyllengahm <span dir="ltr"><<a href="mailto:lunarshuttle@gmail.com">lunarshuttle@gmail.com</a>></span><br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Thanks for fast reply! Sorry, I'm not really sure which example you mean - and if it's applicable to gst-launch. I find ./tests/examples/streams/rtpool-test, but it's c-code and I'm not sure what to make of it...<div> <br></div><div>BR,</div><div>Mathias<br><div><br><br><div class="gmail_quote">2011/2/22 Michael Trimarchi <span dir="ltr"><<a href="mailto:michael@panicking.kicks-ass.org" target="_blank">michael@panicking.kicks-ass.org</a>></span><div> <div></div><div class="h5"><br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">-----BEGIN PGP SIGNED MESSAGE-----<br> Hash: SHA1<br> <br> Hi<br> <div><br> On 02/22/2011 03:16 PM, Mathias Gyllengahm wrote:<br> > Hi again,<br> ><br> > I'd like to let my gstreamer process have realtime priority.
