• Output file names with spaces to file without quotes in bash

  13 mai 2020, par user245115

  So, I wrote a script as a batch file that uses FFmpeg to "concat" several video files on my hard drive.
The script is as follows.

  



  @echo off
title Printing video info...
(for %%i in (
"%USERPROFILE%"/Dropbox/Video1.MKV
"%USERPROFILE%"/Dropbox/Video2.MKV
S:/Exports/Video3.MKV
../../video/Video4.mkv
) do ( if exist "%%i" echo file '%%i' )) > "%~n0.txt"
type "%~n0.txt"
title Copying to compiled video...
"C:\Program Files\ffmpeg\bin\ffmpeg.exe" -hide_banner -f concat^
                  -safe 0 -y -i "%~n0.txt" -c copy "%~n0.mkv"


  



  The problem here is the username on the computer has a space in the name, so the script doesn't work. If I put the quotes with %USERPROFILE%, then the file is detected by the batch script, but the batch script also puts the quotes into the output TXT file, which causes FFmpeg to fail when it hits that file.

  



  The contents of the text file the script outputs to should be :

  



  file 'C:\Users\Name/Dropbox/Video1.MKV'
file 'C:\Users\Name/Dropbox/Video2.MKV'
file 'S:/Exports/Video3.MKV'
file '../../video/Video4.mkv'


  


• Android ffmpeg just convert an image file to video file

  8 février 2018, par Mehmet Kurtgöz

  I want to make a sample video file into video for 30 seconds to show. But I can not do it because I’m not good enough with FFmpeg.

  My code :

   String command[]={
  
                      "-y",
  
                      "-r",
  
                      "1/5",
  
                      "-i",
  
                      src.getAbsolutePath(), // only one image file path
  
                      "-c:v",
  
                      "libx264",
  
                      "-vf",
  
                      "fps=25",
  
                      "-pix_fmt",
  
                      "yuv420p",
  
                      imagesvideoOutput
  
              };

• How to cut and concatenate the file so it is not off-beat when the file I got the bpm from is being muxed ?

  27 janvier 2017, par P. Dee

  I am cutting files with ffmpeg based on the bpm I found in a music file. So let’s assume, the file’s bpm = 120. That means, there are 2 bps and 1 beat every 500ms.

  So I cut a video file with multiples of 500ms length, ie 500ms, 1500ms, 3000ms etc. length. But cutting it using

  ffmpeg -ss start -i fileorig.mp4 -t duration part_number.mp4

  and finally creating a mylist.txt with

  file 'part_1.mp4'
  
  file 'part_2.mp4'
  
  ...

  and adding them via

  ffmpeg -f concat -i mylist.txt -c copy output.mp4

  and replacing the audio track with the music file, makes the video be off-beat after some time.
