• ffmpeg Unrecognized option 'vcodec libx264'

  8 septembre 2021, par Mike

  I have a lambda that is trying to transcode webm files to mp4. It his the lambda using the following code to do the conversion :

  


  const args = [
    "-i",
    inputFilename,
    "-vcodec libx264",
    "-r 30",
    "-y",
    mp4Filename,
];


try {
    const { error, output } = spawnSync(ffmpeg, args);
    console.log(`output: ${output}`);
    console.log(`error: ${error}`);
} catch (error) {
    console.log("ffmpeg failed...");
    console.log(error);
}


  


  In my lambda, I'm seeing the following error :

• FFmpeg - Convert video changing resolution and bitrates

  8 avril 2021, par parvares

  I’m trying to convert a video and change these parameters :

  


  resolution : from 1.280x720 to 640x360 pixels

  


  average bitrate : from 1.410 to 300 kb/s

  


  maximum bitrate : from 1.680 to 2500 kb/s

  


  Sampling rate : from 48.0 to 44.1 kHz

  


  Bit rate audio : 128 kb/s

  


  I used this string with ffmpeg vers. 4.3.2-2021-02-20 full build :

  


  ffmpeg -i input.mp4 -c:v -vf scale=640:360 libx264 -b:v 300k -maxrate 2500k -bufsize 2500k -crf 25 -c:a -ar 44100 libfdk_aac -b:a 128k output.mp4


  


  I get the error : “ffmpeg unable to find a suitable output format for scale ‘640:360’ scale 640:360 : invalid argument”. Could you help me please ?
