  • Showing Image overlay for less than a second in ffmpeg

    31 mai 2016, par lalitsharma1607

    I have to highlight an object in video via ffmpeg, so I am using an overlay image and enabling it for a sec to do so. The one second time is much for this feature as object moves but the overlay does not. So I need to show this overlay for less than a second. Is it possible to give duration milliseconds in

    overlay=20:20:enable='between(t,2,3)

    Here is the command I am using

    String[] complexCommandWatermark = {"ffmpeg", "-y", "-i", orginalFilePath, "-strict", "experimental", "-vf",
    
            "movie=/sdcard/skilltally/overlay_icon.png [watermark]; [in][watermark] overlay=" + leftMargin + ":" + topMargin + ":enable='between(t," + starttime + "," + endTime + ")' [out]"
    
            , "-r", "30", "-b", "15496k", "-vcodec", "mpeg4", "-ab", "48000", "-ac", "2", "-ar", "22050",
    
            newFilePath};

    avcodec/nvenc : split large functions into smaller ones

    Functions names and scopes are from libav. This commit basically moves
    
code around without changing it ; it shouldn’t change any functionality
    
except some small leak fixes on error paths.

  • How to use ffmpeg to handle multiple Stream input

    8 juillet 2019, par 张达芙妮

    I’m using html5 getUserMedia and Electron captureDesktop API to capture user’s screen and camera to make a live broadcast.

    So I wanna to combine these two stream video data into one video output.
    Before I use

    const spawn = require('child_process').spawn;
    
const process = spawn('ffmpeg', [
    
    '-i', '-'
    
    '-c:v', 'libx264',
    
    '-f', 'flv',
    
    'rtmp:xxxxx'
    
]);
    

    
process.stdin.write(data);   // data is read from MediaRecorder

    to covert one stream.

    but when occur two input, Cannot figure out how to input two stream data.
