pukkandan be6202f12b Subtitle extraction from streaming media manifests #247 ... Authored by fstirlitz Modified from: https://github.com/ytdl-org/youtube-dl/pull/6144 Closes: #73 Fixes: https://github.com/ytdl-org/youtube-dl/issues/6106 https://github.com/ytdl-org/youtube-dl/issues/14977 https://github.com/ytdl-org/youtube-dl/issues/21438 https://github.com/ytdl-org/youtube-dl/issues/23609 https://github.com/ytdl-org/youtube-dl/issues/28132 Might also fix (untested): https://github.com/ytdl-org/youtube-dl/issues/15424 https://github.com/ytdl-org/youtube-dl/issues/18267 https://github.com/ytdl-org/youtube-dl/issues/23899 https://github.com/ytdl-org/youtube-dl/issues/24375 https://github.com/ytdl-org/youtube-dl/issues/24595 https://github.com/ytdl-org/youtube-dl/issues/27899 Related: https://github.com/ytdl-org/youtube-dl/issues/22379 https://github.com/ytdl-org/youtube-dl/pull/24517 https://github.com/ytdl-org/youtube-dl/pull/24886 https://github.com/ytdl-org/youtube-dl/pull/27215 Notes: * The functions `extractor.common._extract_..._formats` are still kept for compatibility * Only some extractors have currently been moved to using `_extract_..._formats_and_subtitles` * Direct subtitle manifests (without a master) are not supported and are wrongly identified as containing video formats * AES support is untested * The fragmented TTML subtitles extracted from DASH/ISM are valid, but are unsupported by `ffmpeg` and most video players * Their XML fragments can be dumped using `ffmpeg -i in.mp4 -f data -map 0 -c copy out.ttml`. Once the unnecessary headers are stripped out of this, it becomes a valid self-contained ttml file * The ttml subs downloaded from DASH manifests can also be directly opened with <https://github.com/SubtitleEdit> * Fragmented WebVTT files extracted from DASH/ISM are also unsupported by most tools * Unlike the ttml files, the XML fragments of these cannot be dumped using `ffmpeg` * The webtt subs extracted from DASH can be parsed by <https://github.com/gpac/gpac> * But validity of the those extracted from ISM are untested		2021-04-28 19:02:43 +05:30
