[FFmpeg-user] fading multiple graphic overlays

I'm able to use ffmpeg to fade the same graphic overlays multiple times but I wonder if i'm not using the right approach. When I use 1 overlay the process runs at 35fps, but if I try to overlay the same graphic 3 times the performance drops to 14fps. Thanks, Chris 1 graphic overlay:

[FFmpeg-user] 4.6 kernel timeframe?

When is a fedora release likely to have the 4.6 kernel (I suspect fedora 25)? I saw rumors the nvidia maxwell card firmware will finally be included in 4.6 and it might finally be possible to use nouveau with my graphics card, so I'm just wondering when I might be able to stop fooling with nvidia
