-Obtain the VMAF (Video Multi-Method Assessment Fusion)
-score between two input videos.
+Calulate the VMAF (Video Multi-Method Assessment Fusion) score for a
+reference/distorted pair of input videos.
-The first input is the encoded video, and the second input is the reference video.
+The first input is the distorted video, and the second input is the reference video.
The obtained VMAF score is printed through the logging system.
It requires Netflix's vmaf library (libvmaf) as a pre-requisite.
After installing the library it can be enabled using:
@code{./configure --enable-libvmaf}.
-If no model path is specified it uses the default model: @code{vmaf_v0.6.1.pkl}.
The filter has following options:
@table @option
-@item model_path
-Set the model path which is to be used for SVM.
-Default value: @code{"/usr/local/share/model/vmaf_v0.6.1.pkl"}
-
-@item log_path
-Set the file path to be used to store logs.
+@item model
+A `|` delimited list of vmaf models. Each model can be configured with a number of parameters.
+Default value: @code{"version=vmaf_v0.6.1"}
-@item log_fmt
-Set the format of the log file (csv, json or xml).
+@item model_path
+Deprecated, use model='path=...'.
@item enable_transform
-This option can enable/disable the @code{score_transform} applied to the final predicted VMAF score,
-if you have specified score_transform option in the input parameter file passed to @code{run_vmaf_training.py}
-Default value: @code{false}
+Deprecated, use model='enable_transform=true'.
@item phone_model
-Invokes the phone model which will generate VMAF scores higher than in the
-regular model, which is more suitable for laptop, TV, etc. viewing conditions.
-Default value: @code{false}
+Deprecated, use model='enable_transform=true'.
+
+@item enable_conf_interval
+Deprecated, use model='enable_conf_interval=true'.

+@item feature
+A `|` delimited list of features. Each feature can be configured with a number of parameters.
@item psnr
-Enables computing psnr along with vmaf.
-Default value: @code{false}

-Set the pool method to be used for computing vmaf.

+@item log_path
+Set the file path to be used to store log files.
