Description

url1 = 'https://www.youtube.com/embed/wtTk6KzmhDM?feature=oembed&hd=1'
url2 = 'https://www.youtube.com/embed/W-b2n5cUVYU?feature=oembed&hd=1'
url3 = 'https://www.youtube.com/embed/NjhSgxsOOlU?feature=oembed&hd=1'

url11 = 'https://www.youtube.com/watch?v=wtTk6KzmhDM'
url22 = 'https://www.youtube.com/watch?v=W-b2n5cUVYU'
url33 = 'https://www.youtube.com/watch?v=NjhSgxsOOlU'

import os
url = u1

cmd1 = f"""youtube-dl -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best" --write-auto-sub --write-info-json --sub-lang en --convert-subs srt {url}"""  
msg = f"cmd1: {cmd1}"
print(msg)
os.system(cmd1)

The url1 to url3 are youtube embedded links, which crawled from tag in a website. When I run the code using url1, at the end, the srt subtitle, video and info json has been download successful, but the process didn't exit normally, just stop there. But the same video_id, when I run the code with url11, it do download and exit normally. WHY? I wonder if the youtube-dl has a bug when downloading the youtube embedded url.</p> <p>Looking forward to your reply.</p> </div> </div> <div class="comment"> <div class="user"> <a rel="noreferrer nofollow" target="_blank" href="https://github.com/dstftw"><img src="https://avatars.githubusercontent.com/u/1908898?v=4" />dstftw</a> commented <strong> 4 years ago</strong> </div> <div class="markdown-body"> <p>The log indicates no issues.</p> </div> </div> <div class="comment"> <div class="user"> <a rel="noreferrer nofollow" target="_blank" href="https://github.com/Jokertion"><img src="https://avatars.githubusercontent.com/u/37183438?v=4" />Jokertion</a> commented <strong> 4 years ago</strong> </div> <div class="markdown-body"> <blockquote> <p>The log indicates no issues.</p> </blockquote> <p>The log ensure no problem, but process didn't exit, just stop there!!!
