  • How to get the buffer of the first frame of a video using ffmpeg ? (Node.js)

    12 avril 2024, par Mahmoud Walid

    I am trying to use child_processes and ffmpeg to do this, but it returns this error :

    


    FFmpeg stderr: [AVFilterGraph @ 00000157fd55abc0] No option name near 'eq(n, 0)"'
[AVFilterGraph @ 00000157fd55abc0] Error parsing a filter description around:
[AVFilterGraph @ 00000157fd55abc0] Error parsing filterchain '"select=eq(n\, 0)"' around:
[vost#0:0/libx264 @ 00000157fd574700] Error initializing a simple filtergraph
Error opening output file pipe:1.
Error opening output files: Invalid argument

FFmpeg process exited with code: 4294967274


    


    When I run that command in the terminal, it works fine, but it doesn't work in the code.
Here's the command (terminal version) :
ffmpeg -i input/vid.mp4 -vf "select=eq(n\,0)" -vframes 1 out.png

    


    And heres the code :

    


    import { spawn } from 'child_process';

const inputVideoPath = 'input/vid.mp4';

const ffmpeg = spawn('ffmpeg', [
    '-i', inputVideoPath,
    '-vf', '"select=eq(n\\, 0)"',
    '-vframes', '1',
    '-f', 'mp4',
    'pipe:1'
]);

let buffer = Buffer.from([]);
ffmpeg.stdout.on('data', (data) => {
    buffer = Buffer.concat([buffer, data]);
});

ffmpeg.stderr.on('data', (data) => {
    console.error('FFmpeg stderr:', data.toString());
});

ffmpeg.on('exit', (code) => {
    if (code == 0) {
        console.log('FFmpeg process exited successfully.');
        console.log(`Buffer size: ${buffer.length} bytes`);
    } else {
        console.error(`FFmpeg process exited with code: ${code}`);
    }
});

ffmpeg.on('error', (err) => {
    console.error('FFmpeg error:', err);
});


    


    Note : I know I'm not doing anything with the buffer, I just want it to work first then I'll start working with the output
