• 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);' ?

  @HiltAndroidApp

        } else {

        } 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

  


• HEVC with alpha [closed]

  3 mai 2024, par foxhable

  I trying create HEVC with alpha video from png images through ffmpeg.

  


  When i try, it outputs a video that works, has a transparent background and opens in QuickTime, but does not open in Safari. Then i try creating in prores 4444 codec and convert from macOS Context Menu -> Encode Selected Video Files with HEVC 1080p and Preserve Transparency. It has work - video with transparent background, open in QuickTime and in Safari.

  


  So i tried understand what a difference in meta data and only what i find its working video has HVEC encoder, but not working has Lavc61.5.103 hevc_videotoolbox. Can i somehow programmatically or from utilities like ffmpeg create video with HEVC With alpha, which working like from macOS context menu ? macOS context menu doesnt fit because i cant compress or create many videos

  


  Detail info

  


  I have example of working video. Info from ffprobe

• 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 ?
