• 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 {
            Log.e("FFmpeg", "Failed to initialize FFmpeg: ${ffmpegSession.failStackTrace}")
            initializeFFmpegBinary()

    private fun initializeFFmpegBinary() {

        } else {
            Log.d("FFmpeg", "FFmpeg binary found at $ffmpegBinaryPath")
        }
    }
}


  


  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

  


• 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 ?

  


• Muxing together a .ts file and a sub file causes playback issues in video and audio [closed]

  3 mai 2024, par Meta83

  So I have a .ts file and a converted .dvb sub file (.SRT TO .DVB) that I want to mux togheter using FFMPEG. The mux is a success and the file plays fine in VLC or other modern divce.However I have an older divce (around 10 yeras old) where playback has issues, whenever a line of subs is displayd the picture and and audio gets corrupted and frezzes up and as sson there are no lins everything looks good again and so on. Note that subs are displayd correctly and they are not affected by the issue, only picture and audio is.

  


  I have tried using diffrent command without any luck but here is the most basic command that should work :

  


  ffmpeg -i <video file="file"> -i <dvb file="file"> -f mpegts -c:v copy -c:a copy -c:s copy -copyts <output file="file">&#xA;</output></dvb></video>

  


  Here is the output I get frome FFMPEG :

  Can anyone help me out ? I'm I missing something that is needed for older divaces (divece in question is a Samsung SMT-S5140 STB).
