Split video by chapters (#158)
* New options `--split-chapters` and `--no-split-chapters` * The output/path of the split files can be given using the key `chapter` * Additional keys `section_title`, `section_number`, `section_start`, `section_end` are available in the output template * Alias `--split-tracks` for parity with animelover/youtube-dl * `--sponskrub-cut` and `--split-chapter` cannot work together Closes: https://github.com/blackjack4494/yt-dlc/issues/277 https://github.com/ytdl-org/youtube-dl/issues/28438 https://github.com/ytdl-org/youtube-dl/issues/12907 https://github.com/ytdl-org/youtube-dl/issues/6480 https://github.com/ytdl-org/youtube-dl/pull/25005 Rewritten from the implementation by: femaref and Wattux https://github.com/Wattux/youtube-dl/tree/split-at-timestamps https://github.com/ytdl-org/youtube-dl/pull/25005 https://github.com/femaref/youtube-dl/tree/split-track

The basic usage of `-o` is not to set any template arguments when downloading a single file, like in `yt-dlp -o funny_video.flv "https://some/video"`. However, it may contain special sequences that will be replaced when downloading each video. The special sequences may be formatted according to [python string formatting operations](https://docs.python.org/2/library/stdtypes.html#string-formatting). For example, `%(NAME)s` or `%(NAME)05d`. To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations. Date/time fields can also be formatted according to [strftime formatting](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes) by specifying it inside the parantheses seperated from the field name using a `>`. For example, `%(duration>%H-%M-%S)s`.
|
||||
|
||||
Additionally, you can set different output templates for the various metadata files seperately from the general output template by specifying the type of file followed by the template seperated by a colon ":". The different filetypes supported are `subtitle|thumbnail|description|annotation|infojson|pl_description|pl_infojson`. For example, `-o '%(title)s.%(ext)s' -o 'thumbnail:%(title)s\%(title)s.%(ext)s'` will put the thumbnails in a folder with the same name as the video.

- `release_year` (numeric): Year (YYYY) when the album was released

Available when using `--split-chapters` for videos with internal chapters:

- `section_title` (string): Title of the chapter

- `section_number` (numeric): Number of the chapter within the file

- `section_end` (numeric): End time of the chapter in seconds
|

|

Each aforementioned sequence when referenced in an output template will be replaced by the actual value corresponding to the sequence name. Note that some of the sequences are not guaranteed to be present since they depend on the metadata obtained by a particular extractor. Such sequences will be replaced with placeholder value provided with `--output-na-placeholder` (`NA` by default).

|

For example for `-o %(title)s-%(id)s.%(ext)s` and an mp4 video with title `yt-dlp test video` and id `BaW_jenozKcj`, this will result in a `yt-dlp test video-BaW_jenozKcj.mp4` file created in the current directory.
