try the video like this > youtube-dl --force-generic-extractor https://m.facebook.com/bakhtiar.kamal1/posts/10214187189745894

someziggyman · 2020-10-20T08:32:09Z

Thanks, youtube-dl --force-generic-extractor works, but I assume this is not how it's supposed to work out of the box. Some regex code refactoring is needed.

sebma · 2020-10-20T21:22:29Z

@october262 The generic extractor cannot not choose the best video format for the download.
For one of my videos, it downloads the 240p instead of the 720p :-(

do you see 3 dots ... in the upper right corner of the video ??
it should give you an option to download & save the video

sebma · 2020-10-20T22:26:31Z

@october262 It's not really my video :-), but one of my friends.
And I don't have a FB account (and I don't want one :-) ).
The "..." in the upper right corner of the video proposes a menu with "Report video" and "Copy Link" items.
The "Copy Link" is not a direct link to the video stream :-(

try youtube-dl --force-generic-extractor -f best URL

The only format available with the generic extractor is this one :

$ youtube-dl -F --force-generic-extractor https://www.facebook.com/100052997931710/posts/158984389211491

sebma · 2020-10-21T17:17:38Z

But the resolution given is wrong because the 0 format downloads a video with a 240x426 that is 240p and NOT 720p

october262 · 2020-10-21T19:53:28Z

But the resolution given is wrong because the 0 format downloads a video with a 240x426 that is 240p and NOT 720p

according to this - https://stackoverflow.com/questions/31631535/youtube-dl-dash-video-and-audio-in-highest-quality-without-human-intervention the bestvideo+bestaudio/best will get you the 720p version

try opening this link - https://www.facebook.com/100052997931710/videos/158983125878284/
in a new tab, click the three dots ... select copy URL then youtube-dl -F https://www.facebook.com/100052997931710/videos/158983125878284/
there you can select the available formats

My guest is that it does not support the FB channel ID (I'm not sure how it's called) but only the FB name.

Using --force-generic-extractor worked and downloaded a 400 x 302 video when -F said it was 720x544 so I'm not sure what's going on there. I ended up using https://fbdown.net/ to get the video for now.

someziggyman · 2020-11-28T10:25:26Z

Here's another test URL if needed:
https://m.facebook.com/filharmoniaKosice/videos/667625703956456

Works only with force generic. Hope some day FB extractor is fixed and will work without a hustle as before.

Sepero · 2020-12-08T10:40:26Z

Same issue here. Using -f option with generic extractor doesn't work correctly either. Cheers!

NitroBiedermann · 2020-12-11T09:31:45Z

Also having this issue. Any idea when this can be fixed or improved?

support for most of the videos posted here has been restored(except for the example posted by @RingoTheDog).
