  • Converting a call center recording to something useful

At least one output file must be specified

    So I converted this file to PCM using

    ffmpeg -acodec g723_1 -i 48401-3405-48403--18042018170000.wav -acodec pcm_s16le -f wav outnew1.wav

    But the audio still sound gibberish , I tried many variation and only Goldwave worked but that works on windows and with GUI not cli.

    So how can I convert this file to something useful so that atleast I can listen to it , It feels like a challenge now.

    PS : Use VLC to play audio file

  • How can I concatenate these two video files that are in different formats with ffmpeg ?

    11 juin 2018, par jaybers

    File s.mp4 is created from a photo and a silent audio track was added in.
    File r.mp4 was created using the built in video record on an android tablet.

    I would like to try to match s.mp4 to r.mp4 so that they can concatenate (s then r). Right now, the time base seems off and it plays audio from the r.mp4 but never shows the video. It it always shows the video from s.mp4. I was able to match the tbn of 90k by using -video_track_timescale 90k but I did not know how to match the tbc. It is 180k on one and 59.94 on the other.

    Probe for s.mp4

    ./ffprobe s.mp4
