[vlc-devel] [PATCH 0/6] NVDec v2

[Thomas Guillem]

For information, here is a very quick bench I did on a Linux machine with a nVidia GPU:

H264 4K 30fps:                                                                   
NVDEC: 4% CPU                                                                    
VDPAU: 15% CPU                                                                   
                                                                                 
HEVC 4K 60fps 10bits                                                             
NVDEC: 10%CPU                                                                    
VDPAU: KO

This looks very good for nvdec.
