• Create multiple videos from URL image arrays. Excel, CSV, SQL > FFmpeg or NumPy ?

  11 avril 2021, par kymadic

  I have a large Excel spreadsheet (example below) and I'm looking for an efficient way to generate a video for each row using the first column as the filename videoID.mp4 and with a framerate of 1

  


  Is it possible to use this as an input into FFmpeg somehow ? Perhaps via an SQL database ? I have zero experience with NumPy but it came up during my research. Any suggestions would be much appreciated.

• Including Youtube-dl in FFMPEG not working in Bash (OSX)

  14 juillet 2019, par user1029296

  I am trying to download 5 second samples for a list of youtube video. The traditional approach is to download the entire file with "youtube-dl" and then use "ffmpeg" to split it however you want it.

  I am trying to use the following method : https://github.com/ytdl-org/youtube-dl/issues/622#issuecomment-162337869

  It does work when I include the variables in the command, for example :

  ffmpeg -ss 0 -i $(youtube-dl -f best --get-url https://www.youtube.com/watch?v=ySVi-0RS5vI&t=5s) -t 10 -c:v copy -c:a copy title2.mp4

  However, I am having issues trying to automate the system. Specifically, I would like ffmpeg and youtube-dl to read a file and use the values. I created the file "youtube.txt" which includes the following codes :

  440.8,https://www.youtube.com/watch?v=0-4wOE_DNeA,661.2,881.6,0-4wOE_DNeA

  431.2,https://www.youtube.com/watch?v=006BQU3BFxw,646.8,862.4,006BQU3BFxw

  I am using the following command :

  parallel -j 6 --colsep ',' ffmpeg -ss {1} -i $(youtube-dl -f best --get-url {2}) --t 5 -c:v copy -c:a copy {5} :::: youtube.txt

  However, I get the following errors :

  ERROR: '{2}' is not a valid URL. Set --default-search "ytsearch" (or run  youtube-dl "ytsearch:{2}" ) to search YouTube
  
  --t: No such file or directory

  Would you mind helping me ?

  Thanks !
