Hi,<br><br>If you do not want to use glibmainloop inside qt code see :<br>"qt-opensource-src-4.4.3/include/QtGui/private/qguieventdispatcher_glib_p.h"<br><br>The other way is to use both qtmainloop and glibmainloop, here 3 examples:<br>

hi,<br>
<br>
I need gstreamer for the following: The frames of a video stream need to<br>
be converted to jpeg images. So I connected a<br>
filesrc-demuxer-decoder-jpegenc-identity-fakesink.<br>
The identiry's "handoff"-signal is used to read the current frame and<br>
store it to a file. The storing will be replaced with some more<br>
processing later which is not part of gstreamer. But the problem is that<br>
this stream only encodes the first frame. After that the stream is<br>
"stuck". I did not get any error messages on the bus and the q_main_loop<br>
is still running. So do I have to tell the jpegenc to encode the next<br>
frame or anything?<br>
The lack of doc and sample code is what makes programming gstreamer so<br>
hard for me. That and the fact that I don't really want to use GLib and<br>
main_loops, because it's for a QT app. But QT's phonon is way not enough<br>
for what I need.<br>
<br>
one more (simple) question: does a stream have to have a sink? Would the<br>
fakesink be neccessary in my case?<br>
<br>
