  • 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.
