I am trying to write a simple player application for Mac that takes a directory of BMP images and displays them on screen at a specified FPS. The issue I am facing is how to write the loop that sends the images to the GUI. If I just do a simple loop, the loop runs all the way through and then only shows the last image. What I need is for the loop to run and update the GUI at the same time. I put the loop in a separate thread, but it still does the same thing. Any ideas?
Just a guess, but won't the GUI try to buffer requests until you say "done", or some sufficient elapsed time of inactivity (on your part) means that what has been drawn so far might actually be worth pushing all the way through the render pipeline so you can see it on screen.
Or VideoLAN - Official page for VLC media player, the Open Source video framework! and see how that code looks for the Mac
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
