How to synchronize play/pause of 2 video streams in stereo
I prepare an application in which both left and right channels in stereo mode must display different avi (or mpeg) video streams.
The video must be started / stopped, of course both channels exactly on the same frame. But, due to the fact that 2 python commands are needed to play/pause the 2 "cameras", it sometimes happens that one stops or starts before the other, in which case both streams are no more synchronized. Is there a mean to play / pause 2 video streams exactly on the same frame ? Here an excerpt of my code : Code:
.............. self.leftcam = viz.add(self.leftEyeMovie, viz.TEX_RECT) self.rightcam = viz.add(self.rightEyeMovie,viz.TEX_RECT) leftquad.texture(self.leftcam) rightquad.texture(self.rightcam) ............. def play(self): if self.playBoth: ## 2 commands cannot always act at the same time self.leftcam.play() self.rightcam.play() elif self.playLeft: self.leftcam.play() elif self.playRight: self.rightcam.play() def pause(self): if self.playBoth: self.leftcam.pause() self.rightcam.pause() elif self.playLeft: self.leftcam.pause() elif self.playRight: self.rightcam.pause()

Hi,
Are you noticing a synchronization issue with the sample code you supplied? Media files have a jumpto command which can jump playback to specific time in the video. Other than that, the only way to have the videos be perfectly synchronized is to combine them into a single video that displays them side by side. |
