and both [pix_texture] and [pix_snap] allow for asynchronous DMA-transfers already (though i only added PBO-tarnsfers to [pix_snap] a week ago or so). it's not really documented anywhere (yet), but you can send a [pbo $1( message to both these objects to specify the number of PBOs to use (with "0" being the default behaviour)
Do you mean that since last week pix_snap should be lot's faster than it use to be? i'd like to understand a bit more the use of single / multiple PBO : what happens if 2 pix_video / pix_texture use the same PBO : will it be slower than using 2 different PBO? (since 2nd pix_texture have to wait for the PBO to be free in order to use it)??? same question with a pix_video / pix_texture and a pix_snap : is using 2 PBO lot's faster than using the same PBO (default behaviour)? cheers Cyrille _______________________________________________ Pd-dev mailing list Pd-dev@iem.at http://lists.puredata.info/listinfo/pd-dev
