• FFMPEG in Node.js : Conversion Failed

  11 juillet 2024, par cuneyttyler

  I have a small node.js web app. I use like this in a get request :

  


  app.get('/api/voice/:gender/:voice/:pitch', function(req, res){
        if(req.params.pitch == "1" || req.params.pitch == "1.0") {
            const file = "./voices/" + req.params.gender.toLowerCase() + "/" + req.params.voice + ".mp3"
            res.download(file);
            return
        }

        const inputFile = "./voices/" + req.params.gender.toLowerCase() + "/" + req.params.voice + ".mp3"
        const output_file = "./Audio/Temp/" + req.params.voice + ".mp3"
        ffmpeg()
                .input(inputFile)
                .audioCodec('pcm_s16le') // Set the audio codec to PCM with 16-bit depth
                .audioFrequency(44100) // Set the sample rate
                .on('error', function(err) {
                    console.error('Error while converting:', err);
                })
                .on('end', function() {
                    // res.download(output_file)
                })
                .save(output_file);

    });


  


  It gives Conversion Failed error :

  


  [2024-07-11T18:11:22.880Z] Error while converting: Error: ffmpeg exited with code 1: Conversion failed!&#xA;&#xA;    at ChildProcess.<anonymous> (d:\Dev\Anima\Client\node_modules\fluent-ffmpeg\lib\processor.js:180:22)&#xA;    at ChildProcess.emit (d:\Dev\Anima\Client\lib\events.js:519:28)&#xA;    at ChildProcess._handle.onexit (d:\Dev\Anima\Client\lib\internal\child_process.js:294:12)&#xA;    at Process.callbackTrampoline (node:internal/async_hooks:130:17) {stack: &#x27;Error: ffmpeg exited with code 1: Conversion …Trampoline (node:internal/async_hooks:130:17)&#x27;, message: &#x27;ffmpeg exited with code 1: Conversion failed!&#xA;&#x27;}&#xA;</anonymous>

  


  When I use same code in a node.js desktop(.exe) app, it successfully runs. When I use it in an express.js app, it fails. Error message is not clear. What is the issue ?

  


• How to set min, max and avg bitrate or vbv delay using FFMPEG for livestream in Python ? [closed]

  10 mai 2024, par Tebyy

  I'm trying to set the minimum, maximum, and average bitrate or vbv delay for a WebM livestream in Python using FFMPEG, but it still shows "0" or "N/A". I've checked the documentation, and everything seems correct. I've also searched for solutions online, but none of them have solved my problem. Does anyone know what I might be doing wrong and how it should be done correctly ?

  


  FFMPEG Command :

  


  ffmpeg_command = [
        'ffmpeg', '-f', 'rawvideo', '-pix_fmt', 'bgr24',
        '-s:v', '1920x1080', '-r', '60',
        '-i', '-',
        # '-an',  # Turn off the audio track
        '-c:v', 'libvpx-vp9', '-g', '60', '-keyint_min', '60',
        '-b:v', '6M', '-minrate', '4M', '-maxrate', '12M', '-bufsize', '8M',
        '-crf', '0', '-deadline', 'realtime', '-tune', 'psnr', '-quality', 'good',
        '-tile-columns', '6', '-threads', '16', '-lag-in-frames', '16',
        '-f', 'webm', '-'
    ]

• Unable find an ffmpeg binary for your Android system

  22 juillet 2024, par Ayush Thakur

  Working on a project where I need to use FFmpeg library in Kotlin to work on some audio files. However I'm unable to initialize the ffmpeg library itself.

  


  this is the error I'm getting

  


  Could not find an ffmpeg binary for your Android system. Did you forget calling: 'new AndroidFFMPEGLocator(this);' ?

        } else {

        }
    }
}


  


  Tried using AndroidFFMPEGLocator(this) ; as suggested by the compiler in my code but unknown reference error is coming for the above line of code.

  


  Also tried using FFmpegKit.init(this) function but init is also not being recognised by the compiler
