  • Create a glitch effect at arbitrary points in time using ffmpeg

    21 décembre 2020, par Soren Wray

    I know how to blend two videos into a single video of cross-fading clips with a glitch effect, e.g. every 2.7 seconds, with this command string :

    


    ffmpeg -i input1.mkv -i input2.mkv -filter_complex "[0][1]blend=all_expr='if(mod(trunc(T/2.7),2),min(1,2*(T-2.7*trunc(T/2.7))),max(0,4-8*(T-2.7*trunc(T/2.7))))*A+if(mod(trunc(T/2.7),2),max(0,4-8*(T-2.7*trunc(T/2.7))),min(1,2*(T-2.7*trunc(T/2.7))))*B';[0]volume='if(mod(trunc(t/2.7),2),min(1,2*(t-2.7*trunc(t/2.7))),max(0,4-8*(t-2.7*trunc(t/2.7))))':eval=frame[a]; [1]volume='if(mod(trunc(t/2.7),2),max(0,4-8*(t-2.7*trunc(t/2.7))),min(1,2*(t-2.7*trunc(t/2.7))))':eval=frame[b];[a][b]amix" output.mkv


    


    I would like a similar method, but for a set of arbitrary points in time. I believe a bash script, based on the above command, perhaps with an array of pre-selected cuts, could do the trick, but I lack the expertise.

  • android - how to play two audio file at same time

    29 janvier 2016, par Sajad Norouzi

    I wanna create an karaoke android app. so far, user can listen to the song and record his voice. now I want to let user some editing like setting volume of his voice or setting Reverb effect. I have some library like ffmpeg and sox on android and don’t have problem for mixing two audio, but for setting volume or Reverb wanna play two audio file simultaneously using mediaplayer, however it’s not possible because android doesn’t let us play two audio file with mediaplayer at same time even with two different object of mediaplayer. so, what is the solution ?
