  • what is the best way to append a video file to multiple video files using batch file [on hold]

    5 avril 2017, par JAGGADAKU

    i am beginner with computer programming and i have knowledge of c/c++

    from [https://trac.ffmpeg.org/wiki/Concatenate][1] i have learned that how to merge video files using ffmpeg

    To list all video files containing in a folder

    (for %%i in (*.mp4) do @echo %%i) > mylist.txt

    to concatenate files

    ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4

    This merges all files of a list to one single file.
    but How do i append one video file(main.mp4) at the starting of all the video files listed in mylist.txt ?

    can someone help me ?

    Hello there

    i have tried following code i don’t know what’s wrong with it but it is not `

    @echo off
    
(for %%i in (*.mp4) do @echo %%i) > mylist.txt
    

    
for /F "tokens=*" %%A in (mylist.txt) do (
    
    echo %%A
    
    ffmpeg -i "concat:main.mp4|%%A" -c copy  %%Aoutput.mp4
    

    
)

  • Is ffmpeg running in CPU or GPU ?

    that if the CPU % is more than 90 then the app is running in CPU.

    



    While configuring ffmpeg, I enabled opencl. ffmpeg configurations are,

    



    ffmpeg version ebe0fa0 Copyright (c) 2000-2015 the FFmpeg developers
  built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-4)

    But while running ffmpeg using the command

    



    ffmpeg -i /home/M.mp4 -c:v h264 -preset:v faster /home/out.avi

    



    the CPU% has been more than 90 (375%).

    



    In case of ImageMagick, if I enable opencl while configuring, then the app will run in GPU, i.e., the CPU% will be less than 90. I noticed that.

    



    But in case of ffmpeg, it is GPU accelerated one. Then, Why the CPU% is more than 90% ? Is the ffmpeg running in CPU or GPU ? If it is not, how can I make it to run in GPU ?
