  • Merging audio at specific time with ffmpeg

    19 octobre 2015, par Deepu

    I was trying to merge audio with ffmpeg with the following command but the audio is merging at starting point.

    ffmpeg -i output-1146.mp4 -i org-EOLWAudio.mp3 -filter_complex " [0:a]atrim=start=0,asetpts=PTS-STARTPTS[aud1]; [1:a]atrim=0:250,asetpts=PTS+100/TB[aud2]; [aud1][aud2]amix=inputs=2[aout]" -map 0:v -map "[aout]" -crf 24 -pix_fmt yuv420p -c:v libx264 -c:a aac -strict -2 -ac 2 output-1246.mp4

    With this command it is merging audio streams but not specified point of time.

    I want to merge audio of a mp3 file from 0 to 250 seconds audio to video
    Starting at 4th minute to 8.10 minute.

  • FFmpeg : Concatenating two video files causing static output
