From 65ba8b23f471b96e6f937f2754c729e22bf2cf0a Mon Sep 17 00:00:00 2001 From: Yen Chi Hsuan Date: Sun, 7 Jun 2015 16:34:19 +0800 Subject: [PATCH] [discovery] Rewrite DiscoveryIE (fixes #5898) Discovery.com now uses a completely different approach for serving videos. At least in both test cases brightcove are involved. However, AMF support is necessary for these brightcove videos. As a result, I try to extract videos from the info page ('?flat=1'). The downloaded file can be different from the one in browsers. --- youtube_dl/extractor/discovery.py | 52 ++++++++++++++++++++----------- 1 file changed, 33 insertions(+), 19 deletions(-) diff --git a/youtube_dl/extractor/discovery.py b/youtube_dl/extractor/discovery.py index d3e667528..d6723ecf2 100644 --- a/youtube_dl/extractor/discovery.py +++ b/youtube_dl/extractor/discovery.py @@ -2,19 +2,19 @@ from .common import InfoExtractor from ..utils import ( + parse_duration, parse_iso8601, - int_or_none, ) +from ..compat import compat_str class DiscoveryIE(InfoExtractor): _VALID_URL = r'http://www\.discovery\.com\/[a-zA-Z0-9\-]*/[a-zA-Z0-9\-]*/videos/(?P[a-zA-Z0-9_\-]*)(?:\.htm)?' - _TEST = { + _TESTS = [{ 'url': 'http://www.discovery.com/tv-shows/mythbusters/videos/mission-impossible-outtakes.htm', - 'md5': '3c69d77d9b0d82bfd5e5932a60f26504', 'info_dict': { - 'id': 'mission-impossible-outtakes', - 'ext': 'flv', + 'id': '20769', + 'ext': 'mp4', 'title': 'Mission Impossible Outtakes', 'description': ('Watch Jamie Hyneman and Adam Savage practice being' ' each other -- to the point of confusing Jamie\'s dog -- and ' @@ -24,22 +24,36 @@ class DiscoveryIE(InfoExtractor): 'timestamp': 1303099200, 'upload_date': '20110418', }, - } + 'params': { + 'skip_download': True, # requires ffmpeg + } + }, { + 'url': 'http://www.discovery.com/tv-shows/mythbusters/videos/mythbusters-the-simpsons', + 'info_dict': { + 'id': 'mythbusters-the-simpsons', + 'title': 'MythBusters: The Simpsons', + }, + 'playlist_count': 9, + }] def _real_extract(self, url): video_id = self._match_id(url) - webpage = self._download_webpage(url, video_id) + info = self._download_json(url + '?flat=1', video_id) - info = self._parse_json(self._search_regex( - r'(?s)', - webpage, 'video info'), video_id) + video_title = info.get('playlist_title') or info.get('video_title') - return { - 'id': video_id, - 'title': info['name'], - 'url': info['contentURL'], - 'description': info.get('description'), - 'thumbnail': info.get('thumbnailUrl'), - 'timestamp': parse_iso8601(info.get('uploadDate')), - 'duration': int_or_none(info.get('duration')), - } + entries = [{ + 'id': compat_str(video_info['id']), + 'formats': self._extract_m3u8_formats( + video_info['src'], video_id, ext='mp4', + note='Download m3u8 information for video %d' % (idx + 1)), + 'title': video_info['title'], + 'description': video_info.get('description'), + 'duration': parse_duration(video_info.get('video_length')), + 'webpage_url': video_info.get('href'), + 'thumbnail': video_info.get('thumbnailURL'), + 'alt_title': video_info.get('secondary_title'), + 'timestamp': parse_iso8601(video_info.get('publishedDate')), + } for idx, video_info in enumerate(info['playlist'])] + + return self.playlist_result(entries, video_id, video_title)
