Fix AssertionError when og property not found
On tvp.pl some webpages contain OpenGraph metadata and some don't. If og property is not found, _og_search_description fails with WARNING: unable to extract OpenGraph description; please report this issue on http://yt-dl.org/bug Traceback (most recent call last): File "/usr/home/saper/bin/youtube-dl", line 18, in <module> youtube_dl.main() File "/usr/home/saper/sw/youtube-dl/youtube_dl/__init__.py", line 766, in main _real_main(argv) File "/usr/home/saper/sw/youtube-dl/youtube_dl/__init__.py", line 719, in _real_main retcode = ydl.download(all_urls) File "/usr/home/saper/sw/youtube-dl/youtube_dl/YoutubeDL.py", line 715, in download videos = self.extract_info(url) File "/usr/home/saper/sw/youtube-dl/youtube_dl/YoutubeDL.py", line 348, in extract_info ie_result = ie.extract(url) File "/usr/home/saper/sw/youtube-dl/youtube_dl/extractor/common.py", line 125, in extract return self._real_extract(url) File "/usr/home/saper/sw/youtube-dl/youtube_dl/extractor/tvp.py", line 56, in _real_extract info['description'] = self._og_search_description(webpage) File "/usr/home/saper/sw/youtube-dl/youtube_dl/extractor/common.py", line 331, in _og_search_description return self._og_search_property('description', html, fatal=False, **kargs) File "/usr/home/saper/sw/youtube-dl/youtube_dl/extractor/common.py", line 325, in _og_search_property return unescapeHTML(escaped) File "/usr/home/saper/sw/youtube-dl/youtube_dl/utils.py", line 494, in unescapeHTML assert type(s) == type(u'') AssertionError The patch allows me to use: try: info['description'] = self._og_search_description(webpage) info['thumbnail'] = self._og_search_thumbnail(webpage) except RegexNotFoundError: pass
