Re: [x265] [PATCH] Add VMAF suppport to report per frame and aggregate VMAF score

Thanks. My question is, why not calculate the full VMAF metrics at the end of encode, and write in the per-frame VMAF metric into your CSV file (if the file is incrementally written, you might need to do some weird pointer math, moving to the end of each line etc). Isnt that a better solution

Re: [x265] [PATCH] Add VMAF suppport to report per frame and aggregate VMAF score

I cannot find the implementation of compute_vmaf in the patch attached. I'm not sure why the libvmaf interface for a single frame doesnt include the motion component? Can you point me to this code and vmaf API description? On Mon, Apr 16, 2018 at 5:26 PM, Aruna Matheswaran <

Re: [x265] [PATCH] Add VMAF suppport to report per frame and aggregate VMAF score

Not sure I understand - are you saying you write the frame level VMAF score into the CSV file, and then read it back again to compute the mean? On Mon, Apr 16, 2018 at 3:24 PM, Ashok Kumar Mishra < as...@multicorewareinc.com> wrote: > > > On Mon, Apr 16, 2018 at 2:42 PM, Deepthi Nandakumar < >

Re: [x265] [PATCH] Add VMAF suppport to report per frame and aggregate VMAF score

Why are file reads required to compute vmaf? The recon and original yuv sources are available. Why floating point reads? On Thu, Apr 12, 2018 at 5:31 PM, Ashok Kumar Mishra < as...@multicorewareinc.com> wrote: > > > On Thu, Apr 12, 2018 at 4:43 PM, wrote: > >> #
