Parameters
----------
path: str
Input file path.
stream: int, optional
Stream number, 1-based.
streamByType: str, optional
Select stream by type ('sub' or 'audio').
streamByLang: str, optional
Select stream by 3-letter language code, relies of file metadata.
lang: str, optional
Stream language as 2- or 3-letter ISO code.
enc: str, optional
Character encoding, `None` for auto detection based by `lang`.
fps: float, optional
Framerate.
channels: str or subsync.synchro.channels.ChannelsMap, optional
Audio channels to listen to, could be 'auto' or `None` for auto
selection, 'all' to listen to all channels, or comma separated
channels abbreviation, e.g. 'FL,FR'.
Notes
-----
Here stream number is 1-based (first stream in file has number 1) but
other methods expects 0-based numbers.
