bit_rate: Optional[float]

Bit rate of the stream, in seconds (float or None).

codec: Optional[str]

Codec (str or None).

duration_seconds_from_header: Optional[float]

Duration of the stream, in seconds, obtained from the header (float or None). This could be inaccurate.

num_channels: Optional[int]

The number of channels (1 for mono, 2 for stereo, etc.)

sample_format: Optional[str]

The original sample format, as described by FFmpeg. E.g. ‘fltp’, ‘s32’, etc.

sample_rate: Optional[int]

The original sample rate.

stream_index: int

Index of the stream that this metadata refers to (int).
