  • speed up the video and audio 1.5 times ffmpeg [duplicate]

    23 février 2021, par Mayank Thapliyal

    I have a video which I want to speed up 1.5 times. I gave a check on stackoverflow but I did not got the perfect answer for me (sometimes audio disappears,sometimes audio remains unaffected). I want to speed up my video(including audio) 1.5 times.

    


    Also,if possible, can the command be combined with this command into a single command(I guess it would save my processing time)

    


    ffmpeg -i video$.mp4 -filter_complex "[0]crop=iw:ih/2:0:0[top];[0]crop=iw:ih/2:0:oh[bottom];[top][bottom]hstack" -preset fast -c:a copy video.mp4

    


    Thanks in advance

    


  • Trim and merge audio and video file using ffmpeg

    30 août 2017, par falary

    I’m trying to trim an audio file and then merge it with my video file on android.

    I can merge them together with the command below

    String command[] = {"-i", mOutputFile.getAbsolutePath(), " -i", mOutputAudioFile.getAbsolutePath(), "-c:v", "copy", "-c:a", "aac","-shortest", dest.getAbsolutePath()};

    But i need to trim the beginning (half-second for example) of my audio file before (for synchronization issue). So if you can help me with a single command it would be perfect but maybe i can just run two ffmpeg commands successively but i don’t know how to do that as well. Thanks !

  • Sox mute white noise silences keeping the lenght of the audio file [on hold]

    1er mars 2019, par Lya1981

    I have an audio which is 200 seconds long.
    I run the following command, which removes silences within the threshold specified :

    sox in.wav out.wav silence 1 0.1 1% -1 0.5 1%

    Once those silences are removed, the audio becomes 100 seconds long, which means I am losing my original time stamps.

    I need to basically blank out / mute those silences (they are variations of white noise), leaving equivalent gaps in their place in order to keep the original length and timestamps within the audio.

    Is there any way to do it with exactly the params above, just not trimming it but blanking it out ? They produce the perfect outcome but I really need to keep the time stamps...
    Thank you in advance !
