• How to split a mp4 file into multiple .m4s chunks with one init.mp4 file

  29 novembre 2018, par JAVA Coder

  I am trying to split one audio.mp4 into multiple chunks(each of 10 seconds) with file format of .m4s or .mpd and one init.mp4 .

  1>I have successfully made chunks of 10 secs with one m3u8 file by this command-

  ffmpeg -i song.mp3 -c:a aac -b:a 64k -vn -hls_time 10 -hls_list_size 0 abc.m3u8

  2>Tried this command also

  MP4Box -dash 10000 -frag 1000 -rap -segment-name myDash -subsegs-per-sidx 5 -url-template test.mp4

  But not able to make .m4s chunks with one init.mp4.

  I am attempting to use ffmpeg in a script that take screenshots of a video in my directory and I keep getting the following errors :

  Below is the code snippet from 'prep.py' where the error occurs above.

  


            while i != self.screens:
                image = f"{base_dir}/tmp/{folder_id}/{filename}-{i}.png"
                (
                    ffmpeg
                    .input(path, ss=random.randint(round(length/5) , round(length - length/5)))
                    .output(image, vframes=1)
                    .overwrite_output()
                    .global_args('-loglevel', 'quiet')
                    .run(quiet=True)
                )


  


  The error message does not mention what file it is unable to find so debugging this issue has proven challenging. I am using Windows 10 and I have tried 'cmd', Git-Bash, and PowerShell. I am also using Python Version 3.9.6. Any tips or ideas on how I can debug this issue and get it fixed ?

  


• How to make (output file) take the name from (input mp3 file) in FFMPEG ?

  23 novembre 2020, par Артем

  I am using Windows 7
  
Here is my batch file.
  
This batch file combines mp3 and png. By adding album art to the audio file.
  

  


  @echo off
@setlocal EnableDelayedExpansion
color a
set a=Your_files\*.mp3
set aa=Your_files\*.png
set b="Result\%%~na.mp3"
set c=ffmpeg
set f=-map 0:0 -map 1:0 -c copy -id3v2_version 3 -metadata:s:v title="Album cover" -metadata:s:v comment="Cover (Front)"
for %%a in (%a%) do !set mp3="%%a"!
for %%s in (%aa%) do !set png="%%s"!
%c% -y -i %mp3% -i %png% %f% %b%
exit


  


  When I write this (%% na.mp3) he doesn't know where to get the title from.
  
So it outputs this as the filename (% na.mp3).
  

  


  set a=Your_files\*.mp3
set aa=Your_files\*.png
set b="Result\%%~na.mp3"


  


  That's what I want. Open me
