  • ffmpeg decode and encode for an extension typo

    15 novembre 2022, par William Wong

    I am trying to download some videos from an m3u8 file online. However, the .ts files were (maybe intentionally) changed to .png files. I have tried downloading the .png files and changing them to .ts manually and it plays well.

    


    However, the ffmpeg file seems cannot parse the .png files. I tried to force the output format with -f, but it does not work.

    


    May I know if that is possible to still use the ffmpeg for downloading and converting the stream to mp4 ? I am also open to other methods or simple fixes with bash/ python.

    


  • Scaling an image according to audio (threshold, frequencies)

    11 juillet 2022, par UnlockeerFromFrance

    I am looking for scaling a PNG file according to an audio provided, a frequency range (20hz-1000hz for example) and a threshold, for a smooth effect.
For example, when there is a kick, scale go to 120% smoothly, I would like to make those audio visualizers such as dubstep, etc... where when kicks comes in, their image are "pumping".
First, is it doable with ffmpeg ?
Where to start ?
I found showcqt that takes frequencies in input etc., but its output is a video so I don't think I can use it in my case. Any help appreciated.
