• FFMPEG Drag and Drop sh file

  29 avril 2021, par WFCDefi

  On Windows I have a simple batch file which I drop video files onto to convert to webms, it saves a lot of time as I prefer to just use the same configuration and don't care much about the names.

  


  @echo off 
echo. 
ffmpeg -i %1 -c:v libvpx-vp9 -quality good -cpu-used 2 -b:v 5000k -qmin 15 -qmax 45 -maxrate 500k -bufsize 1500k -framerate 60 -threads 8 -vf scale=-1:1080 -c:a libvorbis -b:a 192k -f webm %1.webm 
pause


  


  I know the .bat file won't really work in Linux (I'm on pop os so pretty much Ubuntu) so with the other lines removed and the %1 changed to $1 it works. It won't do anything if I try dragging and dropping a video file onto it though.

  


  I can type sudo then drag and drop the .sh file followed by a video into a terminal and press enter and it will have the same effect as dragging a video file onto a bat file in Windows.

  


  Is there a way to recreate dragging and dropping a file directly onto another and it executing in Linux or is the terminal the only way ?

• How to extract the sound of a video from two timecodes to a .ts file [closed]

  22 avril 2023, par Imprevisible

  I'm trying to use FFMPEG to extract the audio from a video for a certain period of time and cut it into 5 second chunks, but it doesn't work. Instead, the chunks have different lengths and don't match what I asked for. I tried several solutions, but nothing worked.

  


  From what I understand, the problem could be with the picturerate and the treshold, but I don't know what to do with that information. Here is the command I used :

  


  ffmpeg -loglevel error -accurate_seek -ss 00:00:00 -to 00:00:05 -t 5 -i H:/Films/Tetris.mkv -c:a aac -b:a 128k -ac 4 -vn -map 0:1 -f adts pipe:1


  


  This gave me an audio file of 53s, but if I do from 00:00:05 to 00:00:10, I have an audio file of 4.6s.

  


  If anyone can help me, that would be great. Thanks in advance
