• ffmpeg - concatenate mp4 files + audio from a folder structure

  17 septembre 2022, par Ionut Bejinariu

  I use this batch file to concatenate several .mp4 files and then join them with an audio song.

  


  @echo off

mkdir ".\Export" 
set "sourcedir="  
set "outputdir=Export" 

for %%i in (*.mp4) do echo file '%%i'>> lista.txt
ffmpeg -f concat -safe 0 -i lista.txt -c copy mergedmp4.mp4

for %%F in (*.wav *.mp3) DO ( 
    ffmpeg -i mergedmp4.mp4 -i "%%F" -map 0:v -map 1:a -vcodec copy -c:a aac -b:a 320k "%outputdir%\%%~nF.mp4"
)

del lista.txt
del mergedmp4.mp4


  


  So far so good, It's working

  


  I would describe what will help me more and I need to happen :

  


  I have this folder structure \Video-15-sec\Canal-1\Videos-1, Videos-2 .. Videos-15 or sometimes can be until Videos-20 or more, depends how I organize them.

  


  All of Videos folders have .mp4 files in them and are renamed all the time1.mp4, 2.mp4, 3.mp4 ... 25.mp4 ... 35.mp4 ..etc each of the Videos folders respect the name of file starting with 1.mp4 to how many are in the folder.

  


  The directory structure is like this :

  


  

──Video-15-sec
│       ├───Canal-1
│       │   ├───Videos-1 (.mp4 files in it)
│       │   ├───Videos-2 (.mp4 files in it)
│       │   ├───Videos-3 (.mp4 files in it)
│       │   ├───Videos-4 ...
│       │   ├───Videos-5
│       │   ├───Videos-6
│       │   ├───Videos-7
│       │   ├───Videos-8

  I want to have a separate folder \allmusic where I will have all the music, and the batch file will always export with the name of the song.

  


  all the mp4 files of each separate folder Videos-1, Videos-2 ... Videos-10..., will be concatenated separately and then joined with a single song, each separate folder, with one song each. All the songs and Videos folders in loop, until all my songs are done.

  


  The video created will be exported in a separate folder \Export-all-Videos

  


  Actions of Batch file :

  


  ─Video-15-sec
│       ├───Canal-1
│       │   ├───Videos-1 (concatenate.mp4 files from) + 1 song -> Folder  \Export-all-Videos\name of the song.mp4
│       │   ├───Videos-2 (concatenate.mp4 files from) + 1 song -> Folder  \Export-all-Videos\name of the song.mp4
│       │   ├───Videos-3 (concatenate.mp4 files from) + 1 song -> Folder  \Export-all-Videos\name of the song.mp4
│       │   ├───Videos-4 ...
│       │   ├───Videos-5
│       │   ├───Videos-6
│       │   ├───Videos-7


  


  I hope someone has a solution for this.

  


  Thank you very much

  


• keep connection alive in ffserver

  17 août 2014, par Mohammadhzp

  I have a directory which contain some files,I loop around this files and stream them using ffmpeg to ffserver,the problem is when song is over,the client stop receiving the stream.VLC and jwplayer have this problem-which I tested-(although I can fix this problem in jwplayer by adding repeat : true option but I don’t think it’s such a good idea).

  what I need is an option or some trick in ffserver which keep connection alive(at least for a while) so that if a song is over,the next song start automatically(it take 1 second to switch songs),maybe ffserver have a timeout option ?

• How to import FFmpeg files to Android project

  16 décembre 2019, par Antony

  I followed this https://proandroiddev.com/a-story-about-ffmpeg-in-android-part-i-compilation-898e4a249422 guide to build FFmpeg for Android. I ended up having 4 directories. Which of these do I need to paste on my project folder ? Also, where should I place them ? Inside app directory ?

  

  I’m aware Gradle also need some configuration but the guide above provides information about it.
