  • How to add audio of both the video when overlaying one video over the other in FFmpeg ?

    22 juillet 2022, par Sanyem Nazkani

    I want to overlay V1 video over D2 video and want to use the audio of both V1 and D2. Can someone please help me in this ?

    


    ffmpeg -i D ://python/E1.mp4 -i D ://python/V1.mp4 -filter_complex "[1]setpts=PTS-STARTPTS+10/TB[top] ;[0:0][top]overlay=275:300:enable='between(t,18.20,27.10)'[out]" -shortest -map [out] -map 0:1 -pix_fmt yuv420p -c:a copy -c:v libx264 -crf 18 D ://python/Output.mp4

    


  • Extracting audio from video per video frame (C++) [on hold]

    5 septembre 2015, par PaulZyCZ

    Several days ago I had written an interface (in C) to simple DLL library which processes video in OpenCV using Qt5 framework. There is a function which takes frame ID and returns the raw picture data of the frame (so it can be played in Unity using C#). There is however no function to extract corresponding audio. So I am looking for a way to write such a function.

    I am thinking of a way to extract audio from video file (say MP4 with MPEG-4), with length of the corresponding video frame. But so far I have found only tutorials about extracting whole track (via FFMPEG) either to save or play the sound.

    Is there a way to extract only a "frame" (1/fps seconds of audio) ? Or would it be better to create indexes and extract whole track ?

    Thank you for answers.

    PS : Usual questions deal with whole track, not one frame-length sample specified by video frame ID. I have little knowledge of the FFMPEG and it has been several months since I used it last in uni project.

    I have frame, it’s ID, but no sound to it.

  • Is there a way to concatenate mp4 video files in ffmpeg without video resolution switching ? [closed]

    15 mai 2024, par Micery999

    So i tried this command from windows

    


    (echo file 'first file.mp4' & echo file 'second file.mp4' )>list.txt
ffmpeg -safe 0 -f concat -i list.txt -c copy output.mp4


    


    while making a batch file

    


    Then i concatenate two video's and as soon as the one video ended. It changes resolution, then the video player started to glitch out pixel's like in vlc.

    


    Even if i typed

    


    ffmpeg -safe 0 -f concat -i list.txt -vf scale=640:360 -c copy output.mp4


    


    Nothing happened.
