• lavf/dashenc : set FLAC manifest codec string to "flac"

  14 novembre 2018, par Jan Ekström

  lavf/dashenc : set FLAC manifest codec string to "flac"
  Internally in ISOBMFF the FLAC-in-ISOBMFF draft uses "fLaC"
  
  as the identifier for FLACSampleEntry, and there seems to be no
  
  MPEG-DASH specification for the in-manifest identifier for FLAC.
  After testing the browsers' implementations, it seems like all of
  
  the major browser vendors have decided to utilize the MIME type for
  
  FLAC ("audio/flac") as the identifier. This change set leads to
  
  that string being utilized for FLAC streams instead of the sample
  
  entry identifier ("fLaC"), which is the default behavior.
  Verified by auri_ on IRC to play with the major browsers.
  

  • [DH] libavformat/dashenc.c

• Google speech to text api is partially converting .flac file into text

  12 juillet 2018, par Gemini Jain

  Steps followed :

  1. Converted .mp3 to .flac using ffmpeg.
  2. Ran this command
     gs://xxx/xxx.flac --language-code=en-US --async --encoding=FLAC --sample-rate=44100.
  3. After processing it, is showing result in JSON format, but its not relevant to audio file.

  JSON result looks like :

  {
  
    "@type": "xxx",
  
    "results": [
  
      {
  
        "alternatives": [
  
          {
  
            "confidence": 0.71890223,
  
            "transcript": "I reports everybody."
  
          }
  
        ]
  
      },
  
      {
  
        "alternatives": [
  
          {
  
            "confidence": 0.5876879,
  
            "transcript": "dear, it's your"
  
          }
  
        ]
  
      }
  
  ......
  
  }]}

  Can please someone help me in figuring out why it is not converting the audio files correctly ? Am I missing any tags ?.

• Convert a MP3 file to FLAC using coldfusion

  5 avril 2018, par Rino Raj

  What I am trying to achieve

  I want a generic function in ColdFusion through which I can convert audio files to different format.

  What I have tried

  After referring this java code I was trying to implement this in ColdFusion. I have included the .jar file from this link.

  The code I have tried is included below.

  component { 
  
      remote void function foo() { 
  
          WriteOutput("Method foo() called<br />"); 
  
          // local.path = expandPath("../lib/jave-2.0.jar");
  
          local.javaObj = createObject( 'java', 'java.io.File');
  
          local.AudioAttributes = createObject("java", "it.sauronsoftware.jave.AudioAttributes");
  
          local.Encoder = createObject("java", "it.sauronsoftware.jave.Encoder");
  
          local.EncodingAttributes = createObject("java", "it.sauronsoftware.jave.EncodingAttributes");
  
  
  
          local.EncodingAttributes.setFormat('flac');
  
          // local.AudioAttributes.setCodec('libmp3lame');
  
          //local.EncodingAttributes.setAudioAttributes(audioAttr);
  
          local.mp3file = createObject("java", "java.io.File").init("Manavayanatim.mp3");
  
          local.flacFile = createObject("java", "java.io.File").init("Manavayanatim.flac");
  
          try{
  
              local.Encoder.encode(local.mp3file, local.flacFile, local.EncodingAttributes);
  
          }catch(Exception e){
  
              writeDump("Encoding Failed");
  
          }
  
      } 
  
  }

  Error I am getting

  

  After searching about the error it was seen that ffmpeg-amd64.exe file was missing in the location C:\Windows\System32. So I downloaded and added that. But still I am not able to solve the error.
