• Convert m3u8 File URL to a GIF File [closed]

  30 juin 2023, par nxsi

  I have a m3u8 File URL that I got using the MusicKit API (Apple Music) which is an animated cover art for an album. (A quick side question on that. Is m3u8 the only format that Apple Music returns for animated cover arts ?)

  


  So, Now that I have that m3u8 file URL, I want to convert it to a GIF for the ease of use of GIFs.
I've tried using ffmpeg but I don't really seem to make it work at all with NodeJS.

  


  Here is a sample File URL of what Apple Music returns (https://mvod.itunes.apple.com/itunes-assets/HLSMusic116/v4/cb/ac/9e/cbac9e42-0c8a-9798-0016-52ce447cdc78/P359486356_default.m3u8)

  


  TLDR ;
1- Is m3u8 the only format of animated cover arts that the MusicKit api returns ?
2- Can I convert that m3u8 file URL to a GIF, If so, How ?
3- Are there any other ways than ffmpeg to use in NodeJS ?

  


  I've tried using ffmpeg and the furthest I got was a GIF that was corrupted and not done correctly.
Here is the command I tried :

  


  ffmpeg -i "https://mvod.itunes.apple.com/itunes-assets/HLSMusic116/v4/cb/ac/9e/cbac9e42-0c8a-9798-0016-52ce447cdc78/P359486356_default.m3u8" -vf "fps=10,scale=320:-1:flags=lanczos" output.gif


  


• running ffmpeg.exe from inside bash file [duplicate]

  3 février 2023, par Martin

  Hello I am trying to run ffmpeg from inside a track_cmd.sh file which I run inside command prompt using the command bash track_cmd.sh
My file looks like this :

  


  echo "try1"
C:\Users\marti\Documents\projects\jan2023-rendertune\RenderTune\node_modules\ffmpeg-ffprobe-static\ffmpeg.exe
echo "try2"
# start /d "path" file.exe
start /d "C:\Users\marti\Documents\projects\jan2023-rendertune\RenderTune\node_modules\ffmpeg-ffprobe-static" ffmpeg.exe
echo "try3"
# start "c:\windows\system32" notepad.exe   
start "C:\Users\marti\Documents\projects\jan2023-rendertune\RenderTune\node_modules\ffmpeg-ffprobe-static" ffmpeg.exe   
echo "try4"
#start "" fullPath/file.exe
start "" C:\\Users\\marti\\Documents\\projects\\jan2023-rendertune\\RenderTune\\node_modules\\ffmpeg-ffprobe-static\\ffmpeg.exe
echo "done"


  


  But none of these lines work :

  


  >bash track_cmd.sh
try1
track_cmd.sh: line 2: C:UsersmartiDocumentsprojectsjan2023-rendertuneRenderTunenode_modulesffmpeg-ffprobe-staticffmpeg.exe: command not found
try2
track_cmd.sh: line 5: start: command not found
try3
track_cmd.sh: line 8: start: command not found
try4
track_cmd.sh: line 11: start: command not found
done


  


  I have tried the examples posted in this question :
Bat file to run a .exe at the command prompt

  


  But none work. If I run the command C:\Users\marti\Documents\projects\jan2023-rendertune\RenderTune\node_modules\ffmpeg-ffprobe-static\ffmpeg.exe inside command prompt, I get ffmpeg, so I know the path works.

  


• Can not find file with ffmpeg

  3 août 2018, par P.Ung

  I am programming a server in node.js to process a audio file.
  I save the file with this code :

  app.use(upload());
  
  app.get("/", function (req, res) {
  
  res.sendFile("index.html")
  
  });
  
  //Uploaded files will be saved
  
  app.post("/", function (req, res) {
  
  if (req.files) {
  
      var file = req.files.filename,
  
          filename = file.name;
  
      file.mv("./upload/" + filename, function (err) {
  
          if (err) {
  
              console.log("err");
  
          }
  
          else {
  
              res.send("Done");
  
              console.log(filename);
  
              convert(filename);
  
  
  
          }
  
      })
  
  }
  
  })

  I save the file in my upload directory. There everthing works great but now comes the problem.
  I convert the file with ffmpeg

  function convert(filename) {    
  
  var realName = "./upload/" + filename;
  
  var newName = "./output/" + filename.substr(0, filename.length - 4) + ".flac";
  
  ffmpegN = ffmpeg(realName);
  
  ffmpegN.audioBitrate(16).audioFrequency(16000).withAudioCodec('flac').format("flac").save(outputFile);
  
  
  
  ffmpeg(realName)
  
      .toFormat('flac')
  
      .on('error', (err) => {
  
          console.log('An error occurred: ' + err.message);
  
      })
  
      .on('progress', (progress) => {
  
          // console.log(JSON.stringify(progress));
  
          console.log('Processing: ' + progress.targetSize + ' KB converted');
  
      })
  
      .on('end', () => {
  
          console.log('Processing finished !');
  
      })
  
      .save(newName);//path where you want to save your file    
  
  SpeechToText(newName);
  
  }

  Then I want to pass this file to the google speech api. But then I get the error that the file is not found
  Here is the code for the Speech Api :

  function SpeechToText(path) {
  
  // The name of the audio file to transcribe
  
  const fileName = path;
  
  
  
  // Reads a local audio file and converts it to base64
  
  const file = fs.readFileSync(fileName);
  
  const audioBytes = file.toString('base64');
  
  
  
  // The audio file's encoding, sample rate in hertz, and BCP-47 language code
  
  const audio = {
  
      content: audioBytes,
  
  };
  
  const config = {
  
      encoding: 'FLAC',        
  
      languageCode: 'de-DE',
  
  };
  
  const request = {
  
      audio: audio,
  
      config: config,
  
  };
  
  
  
  // Detects speech in the audio file
  
  client
  
      .recognize(request)
  
      .then(data => {
  
          const response = data[0];
  
          const transcription = response.results
  
              .map(result => result.alternatives[0].transcript)
  
              .join('\n');
  
          console.log(`Transcription: ${transcription}`);
  
      })
  
      .catch(err => {
  
          console.error('ERROR:', err);
  
      });
  
  }

  The thing is that if I upload a file everything works. But if I try it for a second time the error occurs :

  fs.js:646
  
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
  
               ^
  
  
  
  Error: ENOENT: no such file or directory, open
