How many copies are we talking about? I think I would be fine if its just a matter of source1 (input video) + source2 (image to overlay) -> destination (frame with overlay to send to the encoder) Then that should be fine. If not, can you recommend any other image manipulation libraries that could let me do this inplace (the source input frame will be YUV420P , ready to be sent to x264...) Evgeny
