Did you test it on HSW ?
yes, test on hsw. teracom_vlc4.bin Y SSIM extreme 0.998968 U SSIM average 0.999547 V SSIM extreme 0.999989 Y SSIM average 0.999992 U SSIM extreme 0.999995 V SSIM average 0.999995 Libva: (staging) b8d3cf092c9b07cfd909552a3c160b7db3b5a91d Intel-driver: (staging) a6dfb8f7fb601f102b414ac0c9088b5b8e88060f Mplayer: (hwaccel-vaapi) f1ad459a263f8537f6cba3bf479daea61c6104b9 The video size is 720x576 however the display size is 768x576, which size are you using in your testing ? we use video size 720x576 in our testing. (In reply to comment #4) > The video size is 720x576 however the display size is 768x576, which size > are you using in your testing ? For teracom_vlc4.bin, the 65 frame ssim: Y_SSIM = 0.998939 U_SSIM = 0.999989 V_SSIM = 0.999995 MPEG2 pass criterion: ssim > 0.99 |
