StreamMetadata

class torchcodec.decoders.StreamMetadata(duration_seconds_from_header: float | None, begin_stream_seconds_from_header: float | None, bit_rate: float | None, codec: str | None, stream_index: int, media_type: str)

Metadata of a single stream, as reported by the container header.

This is everything that is known about a stream without looking at its content. Streams that are neither video nor audio (subtitles, data) are described by this class and nothing more.

begin_stream_seconds_from_header: float | None

Beginning of the stream, in seconds, obtained from the header (float or None). Usually, this is equal to 0.

bit_rate: float | None

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

codec: str | None

Codec (str or None).

duration_seconds_from_header: float | None

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

media_type: str

Type of media the stream carries (str). One of "video", "audio", "subtitle", "data", "attachment" or "unknown".

stream_index: int

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