  • How do I combine two mp4 files with start and end times ?

    5 août 2020, par ilhan

    I want to combine two mp4 files, let's say first.mp4 and last.mp4, with last x seconds (or by giving starting point) of first.mp4 and first y seconds of last.mp4. Is this possible in one command ?

    


  • How to loop over gif file finite number of times while creating mp4 as output with ffmpeg

    16 mai 2020, par in-user

    I am able to convert gif file to mp4 using this command :

    



    ffmpeg -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4


    



    What I want to do is to loop over gif animation 3 times and convert to mp4.

    



    I am able to do this with 2 shell commands. First one from above and then concatenate the same video 3 times.

    



    ffmpeg -f concat -safe 0 -i <(printf "file '$PWD/video.mp4'\n%.0s" {1..3}) -c copy videoloop.mp4


    



    I have also tried with -ignore_loop 0 option and setting time. It does work but it is not exactly what I am trying to do since I can extend the video but can not make exactly 3 loops.

    



    ffmpeg -ignore_loop 0 -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -t 12 videoloop.mp4


    



    So as you can see I am already able to achieve what I want, but with 2 shell commands :

    



    ffmpeg -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4
ffmpeg -f concat -safe 0 -i <(printf "file '$PWD/video.mp4'\n%.0s" {1..3}) -c copy videoloop.mp4


    



    Is it possible to do this with only one call to ffmpeg ?

    



    I tried with -loop option for the input file. It doesn't work for gifs. I also tried with -stream_loop. It creates something corrupted.

    


  • Encoding sounds to play in a Google Hangouts app with ffmpeg

    12 mai 2014, par user3463570

    I have a Google Hangouts app and I am trying to let the user play a sound that I provide.

    Google has this covered, with its Audio Resource, but it only accepts specifically encoded sound files, PCM 16 wav files.

    I have been trying to encode my files using ffmpeg, but it does not seem to be working.
    Any idea as to what I am doing wrong ?

    Here is my ffmpeg command line :
    ffmpeg -i sound.mp3 -map_metadata -1 -flags bitexact sound.wav

    Thanks for your help
