The graphics card and driver should do that. Use output mode "OpenGL
stereo". This is required for reliable and high-quality active stereo.

If you really really want to drive your glasses manually, use output
mode "Alternating left/right" with your 120Hz display, and in
video_output_qt.cpp function gl_thread::run(), immediately after
swapBuffer(), trigger your glasses to unblock the other eye. 

Problems with this approach:
- Alternating left/right with 120Hz may not work reliably on your system
- Triggering your glasses immediately after swapBuffer may not be
  precise enough for high-quality results
- It is difficult to know which eye needs to be unblocked; it may be
  necessary to check if a swap of left and right eyes are necessary
  each time you start a video.
