// Execute transcription command
ArgumentsBuilder args = Builder
    .Create()
    .AddOptions(options =>
        options.Model("medium")
            .Language("en")

Logging

Capture log output by configuring an ILoggerFactory in the Options class:

E.g. Using a Serilog console logger:

// Create a Serilog logger
Log.Logger = new LoggerConfiguration()
    .WriteTo.Console()
    .CreateLogger();

// Set the global logger factory to use the Serilog logger
MediaTools.Options.SetGlobalFactory(new SerilogLoggerFactory(Log.Logger, dispose: false));

Samples

Sample media was created using FFmpeg.

ffmpeg -y -f lavfi -i testsrc=duration=60:size=1920x1080:rate=30 -c:v libx264 -pix_fmt yuv420p testsrc.mp4
