From d8d24a922adb0646f9f78b2fc4a287a72fa7ff73 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sergey=20M=E2=80=A4?= Date: Sat, 27 Jun 2015 00:36:23 +0600 Subject: [youtube] Extract formats from multiple DASH manifests (Closes #6093) DASH manifest pointed by dashmpd from the video webpage and one pointed by get_video_info may be different (namely different itag set) - some itags are missing from DASH manifest pointed by webpage's dashmpd, some - from DASH manifest pointed by get_video_info's dashmpd). The general idea is to take a union of itags of both DASH manifests (for example video with such 'manifest behavior' see https://github.com/rg3/youtube-dl/issues/6093). --- youtube_dl/extractor/youtube.py | 77 ++++++++++++++++++++++++----------------- 1 file changed, 46 insertions(+), 31 deletions(-) (limited to 'youtube_dl/extractor') diff --git a/youtube_dl/extractor/youtube.py b/youtube_dl/extractor/youtube.py index a3da56c14..fa1a2e544 100644 --- a/youtube_dl/extractor/youtube.py +++ b/youtube_dl/extractor/youtube.py @@ -853,6 +853,13 @@ class YoutubeIE(YoutubeBaseInfoExtractor): else: player_url = None + dash_mpds = [] + + def add_dash_mpd(video_info): + dash_mpd = video_info.get('dashmpd') + if dash_mpd and dash_mpd[0] not in dash_mpds: + dash_mpds.append(dash_mpd[0]) + # Get video info embed_webpage = None if re.search(r'player-age-gate-content">', video_webpage) is not None: @@ -873,34 +880,40 @@ class YoutubeIE(YoutubeBaseInfoExtractor): note='Refetching age-gated info webpage', errnote='unable to download video info webpage') video_info = compat_parse_qs(video_info_webpage) + add_dash_mpd(video_info) else: age_gate = False - try: - # Try looking directly into the video webpage - mobj = re.search(r';ytplayer\.config\s*=\s*({.*?});', video_webpage) - if not mobj: - raise ValueError('Could not find ytplayer.config') # caught below + # Try looking directly into the video webpage + mobj = re.search(r';ytplayer\.config\s*=\s*({.*?});', video_webpage) + if mobj: json_code = uppercase_escape(mobj.group(1)) ytplayer_config = json.loads(json_code) args = ytplayer_config['args'] - # Convert to the same format returned by compat_parse_qs - video_info = dict((k, [v]) for k, v in args.items()) - if not args.get('url_encoded_fmt_stream_map'): - raise ValueError('No stream_map present') # caught below - except ValueError: - # We fallback to the get_video_info pages (used by the embed page) - self.report_video_info_webpage_download(video_id) - for el_type in ['&el=embedded', '&el=detailpage', '&el=vevo', '']: - video_info_url = ( - '%s://www.youtube.com/get_video_info?&video_id=%s%s&ps=default&eurl=&gl=US&hl=en' - % (proto, video_id, el_type)) - video_info_webpage = self._download_webpage( - video_info_url, - video_id, note=False, - errnote='unable to download video info webpage') - video_info = compat_parse_qs(video_info_webpage) - if 'token' in video_info: - break + if args.get('url_encoded_fmt_stream_map'): + # Convert to the same format returned by compat_parse_qs + video_info = dict((k, [v]) for k, v in args.items()) + add_dash_mpd(video_info) + # We also try looking in get_video_info since it may contain different dashmpd + # URL that points to a DASH manifest with possibly different itag set (some itags + # are missing from DASH manifest pointed by webpage's dashmpd, some - from DASH + # manifest pointed by get_video_info's dashmpd). + # The general idea is to take a union of itags of both DASH manifests (for example + # video with such 'manifest behavior' see https://github.com/rg3/youtube-dl/issues/6093) + self.report_video_info_webpage_download(video_id) + for el_type in ['&el=info', '&el=embedded', '&el=detailpage', '&el=vevo', '']: + video_info_url = ( + '%s://www.youtube.com/get_video_info?&video_id=%s%s&ps=default&eurl=&gl=US&hl=en' + % (proto, video_id, el_type)) + video_info_webpage = self._download_webpage( + video_info_url, + video_id, note=False, + errnote='unable to download video info webpage') + get_video_info = compat_parse_qs(video_info_webpage) + add_dash_mpd(get_video_info) + if not video_info: + video_info = get_video_info + if 'token' in get_video_info: + break if 'token' not in video_info: if 'reason' in video_info: raise ExtractorError( @@ -1118,24 +1131,26 @@ class YoutubeIE(YoutubeBaseInfoExtractor): # Look for the DASH manifest if self._downloader.params.get('youtube_include_dash_manifest', True): - dash_mpd = video_info.get('dashmpd') - if dash_mpd: - dash_manifest_url = dash_mpd[0] + for dash_manifest_url in dash_mpds: + dash_formats = {} try: - dash_formats = self._parse_dash_manifest( - video_id, dash_manifest_url, player_url, age_gate) + for df in self._parse_dash_manifest( + video_id, dash_manifest_url, player_url, age_gate): + # Do not overwrite DASH format found in some previous DASH manifest + if df['format_id'] not in dash_formats: + dash_formats[df['format_id']] = df except (ExtractorError, KeyError) as e: self.report_warning( 'Skipping DASH manifest: %r' % e, video_id) - else: + if dash_formats: # Remove the formats we found through non-DASH, they # contain less info and it can be wrong, because we use # fixed values (for example the resolution).
