--tune=ssim option is not supported by vp9 latest build #795

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I tried to use the following cli on GCC build ,

./vpxenc  /home/mcw/testsequences/BasketballDrive_1920x1080_50.y4m --good 
--pass=1 --cpu-used=5 --min-q=4 --cq-level=30 --max-q=45 --end-usage=q 
--limit=30  --tune=ssim  -o out.webm

i am getting the error,

Error: Tried to set control 24 = 1
Failed to control codec: Invalid parameter
Option --tune=ssim is not currently supported in VP9.

Are any other performance metrics options introduced to get ssim values?

The "--tune=ssim" option intended to tune the encoding process towards better 
ssim metric for coded video. It does not change the behavior if SSIM stats is 
being produced or not. --enable-internal-stats at configure, will allow encoder 
to produce VPX flavor SSIM being stored in "opsnr.stt". 

We may re-enable the option "--tune=ssim" in future releases.
