Unable to build fingerprints with ffmpeg on Windows 10 - System.ApplicationException : Invalid argument

[Bryan-Rose]

Describe the bug Running the sample code with the ffmpeg audio service, I am unable to create fingerprints from mp3 or wav files. The wav file worked with the default SoundFingerprintingAudioService

To Reproduce Use the following code and the attached file GHIssue_Sample.zip

I also downloaded the tools from ffmpeg v4.3.2 and have them in the correct location. (Files are copied to the correct output folder on build)

Nuget packages

<PackageReference Include="SoundFingerprinting" Version="8.5.1" />
<PackageReference Include="SoundFingerprinting.Emy" Version="8.5.1" />

public class GHIssue
    {
        public string sampleFile = @"path\to\file\GHIssue_Sample.mp3";

        private readonly IModelService modelService = new InMemoryModelService(); // store fingerprints in RAM
        private readonly FFmpegAudioService ffmpegService = new FFmpegAudioService(); // default audio library

        public async Task StoreForLaterRetrieval()
        {
            var track = new TrackInfo("Sample1", "Title1", "Artist1");

            // create fingerprints
            var avHashes = await FingerprintCommandBuilder.Instance
                                        .BuildFingerprintCommand()
                                        .From(sampleFile, MediaType.Audio)
                                        .UsingServices(ffmpegService)
                                        .Hash();

            // store hashes in the database for later retrieval
            modelService.Insert(track, avHashes);
        }
    }

It seems the version that you have was built without --enable-libsoxr flag. Try the following build v4.4.1 which has the flag enabled: https://www.gyan.dev/ffmpeg/builds/packages/ffmpeg-4.4.1-full_build-shared.7z

Awesome, that fixed it. Thank you!
