  • How to speed up ffmpeg when working with multiple files ?

    6 mai 2019, par OBX

    I have 100,000 files which I need to convert from .mp3 to .wav . However, at the moment it takes 1 minute to convert 10 files each of 1 hour duration.

    Here’s what I tried :

    for i in *.mp3
    
do
    
     ffmpeg -i "$i" -acodec pcm_s16le -ac 1 -ar 16000 "stm/$(basename -s .mp3 "$i").wav"
    
done

    Also tried GNU parallel as well, which takes same time as well :

    find ./set/ -name "*.mp3" | parallel 'ffmpeg -i {} -acodec pcm_s16le -ac 1 -ar 16000 {.}.wav'

    Is there a better hack to process the same in less time ?

  • How to change video speed by ffmpeg ?

    17 mai 2019, par Pooja Jadav

    I’m using ffmpeg for video filter.

    But, When I changed video speed, that time I got issue

    • Audio is longer than video :

      ffmpeg -i INPUT.mp4  -filter:v setpts=0.5*PTS -shortest -y -preset ultrafast OUTPUT.mp4

    I want to set audio’s length same as video’s length.

    • shortest = to extend audio streams to the same length as the video stream

    In my case, shortest is not working. Video file and audio file, both are different and then after merging in a video file. Video’s last frame stop and audio is continued working.

  • ffmpeg speed up video - Windows

    19 mars 2019, par Flash Thunder

    In manual it says :

    ffmpeg -i input.mkv -filter:v 'setpts=0.5*PTS' output.mkv

    But when I run :

    ffmpeg -i input.mp4 -filter:v 'setpts=0.5*PTS' speedup.mp4

    I get an error :

    [AVFilterGraph @ 0000000002500600] No such filter: 'setpts=0.5*PTS'
    
Error opening filters!

    Not sure if it means that filter can’t be opened at all or simply this filter is not available.

    How do I run it correctly ? Or maybe my release does not support it, then where can I get the release that would work right ? Win32/x64 binary
