<p class=MsoNormal style='text-align:left;direction:ltr;unicode-bidi:embed'>We implement
our own DeviceSource class. In this class we implement doGetNextFrame in the following
(logic) way. We remove all the unnecessary implementation details so you can

<p class=MsoNormal style='text-align:left;direction:ltr;unicode-bidi:embed'>As
you can see we would like to feed the Live555 frame by frame from the live source.
However, after some calls of the function doGetNextFrame the fMaxSize is
smaller than fFrameSize and the application is in deadlock state. <o:p></o:p></p>
<p class=MsoNormal style='text-align:left;direction:ltr;unicode-bidi:embed'>We
do not understand what should we do in order to eliminate this state. <o:p></o:p></p>
<p class=MsoNormal style='text-align:left;direction:ltr;unicode-bidi:embed'>We
can give part of a frame to Live555 but then it means that we are not going to
feed the Live555 library in frame by frame scenario. (We can build a byte buffer
between the live source and live555 but we do not sure it is the right way) <o:p></o:p></p>
