• MPD doesnt load ffmpeg as decoder

  10 août 2022, par dmSherazi

  I am using openwrt 21.2.3 and mpd on it. I have compile mpd full and libffmpeg full as well as ffmpeg-full packages.
But my mpd wont load ffmpeg as decoder. Also tried to force it by adding decoder { plugin “ffmpeg” enabled “no” }” line to /etc/mpd.conf

  


  below is my mpd.conf

  


  log_file "syslog"

bind_to_address "127.0.0.1"
bind_to_address "192.168.1.16"

input {
    plugin          "curl"
}

audio_output {
    type            "alsa"
    name            "sun4icodec"
    device          "plug:dmix"
    mixer_control   "Power Amplifier"
}

decoder {
     plugin  "ffmpeg"
     enabled  "yes"
}


  


  the mpd —version output is as follows

• flient-ffmpeg getting error as "ffmpeg exited with code 1 : pipe:0 : Invalid data found when processing input"

  6 avril 2023, par Abhishek Rawal

  I am trying to create API where i need to get uploaded video and create thumbnail from that video. But conditions are :

  


  

  • Video should not store on local disk

  


  • Once thumbnail is create it should not store on local disk, instead it should directly uploaded to AWS s3 bucket.

  


  


  Following is the code i am trying with :

  


  


  


  const ffmpeg = require('fluent-ffmpeg');
const stream = require('stream');

router.post('/thumbnail', upload.any(), (req, res) => {
  const videoBuffer = req.files[0].buffer;
  
  let readableVideoBuffer = new stream.PassThrough();
    readableVideoBuffer.write(videoBuffer);
    readableVideoBuffer.end()
    
  let bufferStream = new stream.PassThrough();
  
  ffmpeg(readableVideoBuffer)
    .on('filenames', function(filenames) {
      console.log('Will generate ' + filenames.join(', '))
    })
    .on('end', function() {
      console.log('Screenshots taken');
    })
    .on('error', (err) => {
      console.log(err);
    })
    .screenshots({
      count: 4,
      size: '100x100',
      timestamps: ['00:00:01.000'],
    })
    .writeToStream(bufferStream, { end: true });  /* while using this statement i am getting error */
    
    const buffers = [];
    bufferStream.on('data', function (buf) {
      buffers.push(buf);
    });
    bufferStream.on('end', function () {
      const outputBuffer = Buffer.concat(buffers);
      // use s3 bucket code here
      console.log('outputBuffer===========>', outputBuffer)
    });
})

  


  


  



  so while calling this API my app is crashing and i am getting error as :

  


  


  Error : ffmpeg exited with code 1 : pipe:0 : Invalid data found when
processing input

  


  


  Blockquote

  


  If i am not using this statement :

  


  


  .writeToStream(bufferStream, end : true ) ;

  


  


  then able to save file but in local disk, which is not required in my case.

  


  Please help me to understand what is wrong in this code, how i can resolve it.
Any type of help is appreciated.

  


• ffmpeg_kit_flutter commands work on some devices but not on some other devices

  5 août 2023, par eashhh

  I have been trying to create videos from a series of images with similar formats using the ffmpeg_kit_flutter package. While using the package, I have encountered an issue where the video generation works on certain devices but not on my Android device (Android 10). Below are the code snippets I have been using for the video generation process.

  


  I have invoked the videoCreator() function in the following manner.

  


   Future<void> videoCreator() async {&#xA;    if (await Permission.storage.request().isGranted) {&#xA;      print(&#x27;generation initiated&#x27;);&#xA;      outputPath = File(&#x27;/storage/emulated/0/Download/output123.mp4&#x27;).path;&#xA;      String commandToExecute = &#x27;-framerate ${framerate.toInt()} -i &#x27;&#xA;          &#x27;\&#x27;$videoDirectory/%d.jpeg\&#x27;&#x27;&#xA;          &#x27; -q:v 1 -y $outputPath&#x27;;&#xA;      print(&#x27;$commandToExecute&#x27;);&#xA;      await FFmpegKit.execute(commandToExecute).then((session) async {&#xA;      final returnCode = await session.getReturnCode();&#xA;&#xA;</void>

  


  The output from debug console is as follows :

  


  I/flutter ( 5871): generation initiated
I/flutter ( 5871): -framerate 12 -i '/data/user/0/com.example.test_project/app_flutter/1/%d.jpeg' -q:v 1 -y /storage/emulated/0/Download/output123.mp4
I/flutter ( 5871): Loading ffmpeg-kit-flutter.
D/ffmpeg-kit-flutter( 5871): FFmpegKitFlutterPlugin com.arthenica.ffmpegkit.flutter.FFmpegKitFlutterPlugin@8324d61 started listening to events on io.flutter.plugin.common.EventChannel$IncomingStreamRequestHandler$EventSinkImplementation@50da4a8.


  


  And also to determine whether the video generation was successful or not, the code checks the return code obtained from the session. If the return code indicates success (using the ReturnCode.isSuccess() method), it prints "Success !" to the console else prints "Failure !" wrt to the following conditions given :

  


  
        if (ReturnCode.isSuccess(returnCode)) {
          print("Success!");
          setState(() {
            processing = false;
            status = true;
          });
        } else if (ReturnCode.isCancel(returnCode)) {
          print("Cancelled!");
          setState(() {
            processing = false;
            status = false;
          });
        } else {
          print("Failure!");
          print(await session.getFailStackTrace());
          print("Failure!");
          print(await session.getOutput());
          setState(() {
            processing = false;
            status = false;
          });
        }


  


  But I continue to receive "Failure !" messages in the debug console.

  


  I/flutter ( 5871): Failure!
I/flutter ( 5871): LightThemeSet
I/flutter ( 5871): null
I/flutter ( 5871): Failure!


  


  I attempted the following approaches to resolve the issue :

  


  


  1. Tried changing the output path for the generated video.

     


  


  2. Tried updating the required storage permissions in the AndroidManifest.xml file. Currently the permissions include the standard READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions used for the older android versions and the MANAGE_EXTERNAL_STORAGE permission used for newer versions

     


  


  3. Tested the app on various Android emulators with different configurations where it worked properly.

     


  


  


  Any sort of help would be appreciated !
Warm regards
