  • Changing Audio Volume using FFmpeg Android Error

    23 août 2018, par kataroty

    I am using FFmpeg and I need to change the volume of the Audio.

    This is the command that should change the volume of the audio :

    ffmpeg -i input.wav -filter:a "volume=1.5" output.wav

    I read from somewhere that it had to overwrite the file if it already existed so either one had to delete the file or use -y. When I tried to do it without the -y command it never got to onSuccess() or ´onFailure(), but it always printed out the onStart() message.

    String[] cmdy = { "-i -y" , pcmtowavTempFile.toString(),  "-af", "volume=5", pcmtowavTempFile.toString()};
    ffmpeg.execute(cmdy, new ExecuteBinaryResponseHandler() {

        @Override
        public void onStart() {
            System.out.println("ayy: onStart");
        }

        @Override
        public void onSuccess(String message) {
            System.out.println("ayy: onSuccess");
            super.onSuccess(message);
        }
        @Override
        public void onFailure(String message) {
            System.out.println("ayy: onFailure " + message);
            super.onFailure(message);
        }
});

    At the moment I get this error:

Unrecognized option 'i -y'.

    Which clearly states that it does not recognize option i -y, but also as I said earlier then if I remove the -y it never gets to onSuccess() or onFailure().

    help me to find a solution. Thanks.

  • export all .png file in a folder to mp4 using ffmpeg : BASH script

    23 août 2018, par Dino

    I have a command line that works in a Linux evironment:

    find . -name '*.png' ! -name 'legend_*' -exec cat {} \; | ffmpeg -f image2pipe -r 10 -i - -pix_fmt yuv420p -y -an -sn -movflags +faststart -crf 23 -preset slow movie_x_wake_cp_tot_orient_x.mp4

    It selects all png files (escluded the ones beginning with 'legend') and the result is passes to ffmpeg. The problem is that I cannot use it in a bash script because of the pipe |. With my script I navigate to the directory where the file are, do you know how to pass the files I would like to export as argument of ffmpeg (excluding the ones beginning with 'legend').

    I presume it will be something like:

    ffmpeg ('*.png' ! -name 'legend_*') -f image2pipe -r 10 -i - -pix_fmt yuv420p -y -an -sn -movflags +faststart -crf 23 -preset slow movie_x_wake_cp_tot_orient_x.mp4

    Thank you for your help.

  • FFMPEG join multiple video lost audio

    23 août 2018, par Ankur Tripathi

    I am trying to join 2-3 videos it's working when all video has audio or without audio...

    Command= "-f concat -i files.txt -codec copy output.mp4"

    File.txt

    file '0.mp4'

    file '1.mp4'

    file '2.mp4'

    Now the issue is when 0.mp4 is without audio and 1.mp4 is with audio and when i join these videos full audio lost in output.. output will be without audio.

    I want this join with all as it is like if 0.mp4 without audio then audio will not play for this and 1.mp4 play audio should play...

  • FFmpeg - Buffer queue overflow, dropping - when combining 2 videos and using concat, hstack and trim

    23 août 2018, par Mayank

    I am trying to merge two videos using concat and hstack but getting buffer overflow error resulting in the one of the video getting paused for few seconds.

    I tried adding fifo and h264 video codec as suggested on this forum but the issue persists.

    Can someone please let me know the issue in this command? Many thanks in advance.

    ffmpeg -i 1_a.opus -i 2_a.opus -i 1_v.mp4 -i 2_v_bars.mp4 -filter_complex "[1:a]adelay=15720|15720[a1]; [0:a][a1]amix; [3:v]trim=0:15.81,geq=0:128:128,fifo [silence]; [silence][3:v]concat,fifo [3_v_silence]; [3_v_silence][2:v]hstack,fifo" -vcodec libx264 -strict experimental -y out_fifo_h264_2.mp4
