Thank you for the links FL53. Indeed I already know the callbacks lock/unlock but it is not the most efficient, I mean there are copies between gpu and cpu. I would like to have a zero copy pipeline, in other words stay on gpu in the whole pipeline.

Ok, is there a workaround to fix this bug when using libvlc instead of VLC player ? I mean a special param to ignore data tracks or something else ?
