[Bino-list] Video sync on 2-GPU passive stereo

[Stefan Eilemann]

Hi Martin, all,

Right now I'm debugging an issue with the latest HEAD of bino, and I need at 
least a few pointers. Our setup uses two GPUs to drive a passive stereo,  Full 
HD projection. During playback, the left and right eye occasionally show 
incoherent frames. I verified this by using the same movie for both eyes. 
Whenever the movie playback is stopped, the two images match perfectly. The 
movie is a FullHD loss-less H.264, so frame drops are possible. The display 
outputs have a refresh rate of 25Hz, which matches the movie framerate. My 
command line is:

env __GL_SYNC_TO_VBLANK=1 ./src/bino -i separate-left-right 
/media/left/2012.02/BBP_Movie_25_MPEG-4_Left.mp4 
/media/left/2012.02/BBP_Movie_25_MPEG-4_Left.mp4 -o equalizer --eq-config 
movie.eqc -b

Ideas?


Cheers,

Stefan.

PS: movie.eqc is attached.
PPS: I checked in some simplifications in player_equalizer.cpp
