• What is the best way to fill AVFrame.data

  21 septembre 2015, par Tim Hsu

  I want to transfer opengl framebuffer data to AVCodec as fast as possible.

  I’ve already converted RGB to YUV with shader and read it with glReadPixels

  I still need to fill AVFrame data manually. Is there any better way ?

  AVFrame *frame;
  
  // Y
  
  frame->data[0][y*frame->linesize[0]+x] = data[i*3];
  
  // U
  
  frame->data[1][y*frame->linesize[1]+x] = data[i*3+1];
  
  // V
  
  frame->data[2][y*frame->linesize[2]+x] = data[i*3+2];

• New proposed ePrivacy Regulation and why Piwik might not need tracking consent compared to Google Analytics & co

  11 janvier 2017, par InnoCraft — Community

  The EU is proposing new ePrivacy Regulations. The proposed Regulation on Privacy and Electronic Communications will increase the protection of people’s private life and open up new opportunities for business.

  

  The new ePrivacy Regulation proposal

  The proposal mentions several changes for example to the “Cookie Law” where no longer a cookie consent will be needed when the cookies improve the user’s internet experience, for example to remember the shopping cart history or when completing a form over several pages.

  However, consent to track a user’s behaviour may be needed in the future, unless the analytics data collection is hosted on the first-party website.

  From TheRegister : O’Neil noted a minor change in which visitors to a website for analytics purposes do not require consent, as long as any personal data collected is only processed by the first party.

  

  First party Analytics respecting privacy

  Piwik is an open-source analytics platform that is used on more than 1 million websites and apps in over 150 countries, and available in more than 50 languages. The difference with other analytics solutions is that you can download and install Piwik on your own infrastructure. Websites and mobile apps tracking users with their own Piwik very likely won’t require a consent from their users if these regulations become reality.

  We have regularly written about why privacy matters, or more recently 11 ways Piwik Analytics helps you to protect your visitors privacy.

  Besides the standard Piwik features, there are Premium Features that let businesses and organizations further maximize their success based on the tracked data. Need help in hosting Piwik on premise ? InnoCraft are THE Piwik experts and know it best as it is the company of the makers of Piwik. InnoCraft provides support subscriptions and enterprise packages to help you setting up, configuring and maintaining Piwik on your infrastructure as well as offer training and custom development.

  

  We’re excited to be building the best digital analytics platform which respects our privacy on the Internet.

  Thank you for being a valued member of the Piwik community !

• 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 ?.
