Downloading a Facebook Live video during broadcast

[Nico Darko]

Hi,

I'm trying to download Facebook live videos during their broadcast (I have to since they disappear when the live is over) but with no success. Anyone knows a way to do that? Thanks.

ffmpeg -user_agent "x" -referer "https://www.facebook.com/" -i ".mpd link" -c copy FBLive.mp4

Use this Chrome extension to get the .mpd link. I don't know why, but first seconds of download have video and audio out of sync.

PS: It also works for Instagram live video, but you must to change the referer link to "https://www.instagram.com/".

I get a HTTP 403 error forbidden (access denied).

Replace "x" with your user agent.

Hi. I get a "Output file 0 does not contain any stream".
Also is the user agent suppose to be something like Chrome/88.0.4****.1*0 ?

[lfer94]

That is the user agent

Hi. I get a "Output file 0 does not contain any stream"

I had that same problem, but because I misspelled the command line. Instead of writting:

ffmpeg -user_agent "Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.146 Safari/537.36" -referer "https://www.facebook.com/" -i "mpd link" -c copy FBLive.mp4

I wrote:

ffmpeg -user_agent "Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.146 Safari/537.36" -referer "mpd link" -c copy FBLive.mp4


Anyway, there's an easier way to download live fb videos using Streamlink.

streamlink "mpd link" best -o FBLive.mp4

Ok thanks, how does streamlink work though?

[lfer94]

It works the same as ffmpeg, youtube-dl, etc.

That's what I thought but what .exe file do I use? For ffmpeg there's just one, that I put in the same folder as the .bat file. With streamlinks, a bunch of files were installed, and the bat file is not working. I'm not sure what to do.

you must start cmd from the folder where you have the .exe files (yt-dl, ffmoeg, or streamlink) and then launch from the command line. you don't have to run .exe files...
then copy and paste string at post #6 by lfer94

Thank you, it's working!
I guess I didn't need to run and install streamlinks then.

After the installation, you just must open cmd to any folder you want to download the video or do what lomero said. Both ways work without any problems.
