Summary of the bug:
When built with libvmaf v2.0.0 or later, attempting to invoke the libvmaf
filter with FFmpeg (with the vmaf_v0.6.1.pkl file in the correct location)
will fail with the following error:
{{{
libvmaf INFO `compute_vmaf()` is deprecated and will be removed in a
future libvmaf version
libvmaf WARNING could not read model from path:
"/usr/local/share/model/vmaf_v0.6.1.pkl"
libvmaf WARNING pkl model files have been deprecated, use json
libvmaf ERROR problem loading model file:
/usr/local/share/model/vmaf_v0.6.1.pkl
[Parsed_libvmaf_0 @ 0x55f2b8286f80] libvmaf encountered an error, check
log for details
Error while filtering: Invalid argument
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #1:0
}}}
Currently the default value for the model_path parameter in the libvmaf
filter is "/usr/local/share/model/vmaf_v0.6.1.pkl". However, as the error
message implies, support for .pkl models was removed in
[https://github.com/Netflix/vmaf/releases/tag/v2.0.0 VMAF 2.0.0] and .json
models are used instead.
In addition, v2.0.0 added support for built-in models
(`-Dbuilt_in_models=true` build option, enabled by default). So having a
default model path probably wouldn't even be required.
How to reproduce:
{{{
ffmpeg -r 30 -i encoded.webm -r 30 -i original.mp4 -an -sn -lavfi libvmaf
-f null -
}}}
