cutcutcodec.core.analysis.ffprobe.get_slices_metadata

cutcutcodec.core.analysis.ffprobe.get_slices_metadata(filename: Path | str | bytes, slice_type: str = 'frame') → tuple[list[list[str]], list[ndarray]][source]

Get the packets informations for all streams.

Parameters

filenamepathlike: The pathlike of the file containing streams.
slice_typestr: The type of slices to decode, ‘frame’ or ‘packet’. ‘frame’ is slower but more accurate and informative. ‘packet’ is faster but less acurate.

Returns

headerslist[list[str]]: For each stream, the name of the columns.
infos: list[np.ndarray]: For each stream, the 2d str array. Each row correspond to one packet.
