Glibmm:Threads

[Toby Roworth]

Hello

I'm currently writing a program that decodes video and displays it onto
a secondary screen using OpenGl, with a GTKmm GUI on the first screen.
However the video decoding is quite processor intensive, and maxes out
one of my processors, without the other getting a look in. This prevents
the GUI from operating whilst video is decoding.

I have attempted to solve this by putting the decoding loop inside a
Glibmm::Thread, but this does not seem to have any effect - is this
likely to be because I'm using the wrong tool for the job, misusing the
right tool or something else.

Any help appreciated

Toby

By what I've read on this list, you're problem may be related to gtkmm
event handling and threads.  You may want to search the list
(http://marc.info/?l=gtkmm) for something along these lines.  I'd
encourage you to try gstreamermm, but it may not be stable enough for
general usage yet, though it does have a media player example that uses
gtkmm.
