 "-to","00:02:50",
 "-c:v", "copy", 
 "-c:a", "copy", 
 "output3.mp4"






 ])
 ffmpeg.stderr.on('data', function(data) {
 console.log('ffmpeg stderr data = '+data );
 });

}

How to convert messed-up .vtt sub file from youtube-dl —write-auto-sub download ?
27 septembre 2023, par perry_the_pythonMy goal is to download a YouTube video with auto-generated subtitles in a separate file like
.vtt,.srt, etc.

I am currently trying to achieve this with
youtube-dlbut I am open to other solutions if needed.

When I run the following command, it downloads the video as
.mp4(which is fine) and a separate.vttfile, but the.vttseems to be messed-up somehow and displays all the text for the whole clip at once instead of the specified times.

Command I am running :


youtube-dl --write-auto-sub https://www.youtube.com/watch?v=Roc89oOZOF4&list=PLJBo3iyb1U0eNNN4Dij3N-d0rCJpMyAKQ&index=45


Downloads this .vtt :

I have read that this may be done on purpose by YouTube.


Even if this is true, is there any way to convert this
.vttto a usable format or simply download correctly-formatted auto-generated subtitles from YouTube ?

Python, FFMPEG, cmd-line preferred, but anything is helpful !


Thanks ! Any and all assistance is greatly appreciated !

how to download panopto videos using ffmpeg ?
22 novembre 2022, par RainBatI want to download a panopto video, which has two separate streams, a main and secondary.

for example :Getting Started welcome to Panopto


when i download each of them with ffmpeg using
ffmpeg -i INDEXLink -c copy "FileName.mkv",
they aren't of same length one is 4:08 and the other is 3:24, this is just in this example in other videos it might be double the other in length.

is it possible to download the two streams as they are displayed in the website under length 3:24 ?
