NS_E_EXPECT_MONO_WAV_INPUT
The preprocessing feature requires mono WAV input
NS_E_EXPECT_MONO_WAV_INPUT (0xC00D1BA1) is specific to a voice-analysis/optimization path that expects a single-channel WAV source. It does not mean the audio decoder is generally missing or that stereo media cannot otherwise be encoded.
Verify the input before conversion
Record container, PCM/compressed format, channel count, sample rate, and the preprocessing feature enabled. Check the format actually presented to that feature, not only the original file extension.
Correction
Supply a supported mono WAV/PCM source to the feature or disable the optimization that requires it. Keep output bitrate and audience settings unchanged while validating this input-format decision.
