[osg-users] [osgPlugins] Multiple video textures using ffmpeg plugin

[Michael Maurus]

Hello everyone,

I am currently trying to display a video (mp4) on a textured quad using the osgmovie example. When displaying two of those, I suddenly get a frame drop from 60fps to 12fps.

So my question: what's the proper way to to this without performance issues? 

I am not sure how the ImageStream class works in the background. Already looked at the source code but I couldn't figure out, if the current video frame will be loaded to the graphics cards every frame or the whole video will be uploaded to GPU memory

Thank you!

Cheers,
Michael
