[YouTube] Fail downloading a video in particular #14712

Closed vlakoff closed 6 years ago

vlakoff commented 7 years ago

youtube-dl fails to download this video in particular: https://www.youtube.com/watch?v=AkI8MvKk64I

I have no trouble downloading other videos, including the other videos of this YouTube channel.

Try : youtube-dl.exe -f 136+140 "https://www.youtube.com/watch?v=AkI8MvKk64I"

vlakoff commented 7 years ago

Thanks. It gives me separate video and audio files, still better than nothing.

Yet, youtube-dl should be able to handle this video as regular.

al1fr commented 7 years ago

To mix video + audio, you need to put ffmpeg.exe in same directory as youtube-dl. (ffmpeg 32: 'http://ffmpeg.zeranoe.com/builds/win32/static/?C=M&O=D') (ffmpeg 64: 'http://ffmpeg.zeranoe.com/builds/win64/static/?C=M&O=D')

vlakoff commented 7 years ago

By adding ffmpeg.exe, the video and audio files are now muxed with your -f 136+140 option.

Interestingly, now I can also download the video without format options. However, I get a warning, the result is a mkv file, and the video is 1080p (usually I get 720p, even when 1080p is available, which is fine as I don't need the extra quality of 1080p).

Long story short, would it be possible to improve youtube-dl's handling of videos like this one?

Hrxn commented 7 years ago

Yes, but this warning

WARNING: Requested formats are incompatible for merge and will be merged into mkv.

is normal. It's a result of the default format selection used by youtube-dl and the formats offered by YouTube.

vlakoff commented 6 years ago

This video really can't be downloaded without a muxer?

rautamiekka commented 6 years ago

^ Basically any YT vid can, but you're sacrificing vid and audio quality to some extent.

--format "best" "https://www.youtube.com/watch?v=AkI8MvKk64I" will get you the best single-package option YT offers. You won't get the very best vid and very best audio you'd get by default, but you can play the file right away and it's identical to the one you see on YT.

vlakoff commented 6 years ago

The issue is precisely that youtube-dl fails downloading the video if there is no muxer installed.

al1fr commented 6 years ago

The file with the best resolution is probably corrupted. If you really don't want use a muxer, it's possible to download the video 640x360 with audio 96k :

youtube-dl.exe -f 18 "https://www.youtube.com/watch?v=AkI8MvKk64I"

It works.
