• How to make a custom Iterator

  27 décembre 2022, par Anony Mouse

  I am struggling creating my own custom Iterator. I currently have Class that provides me with Frames
and I have to create an Iterator to get a Stream of Frames which i get by turning Frames -> Spliterator -> Stream

  


  StreamSupport.stream(Spliterators.spliteratorUnknownSize(<iterator>, Spliterator.ORDERED), false);&#xA;</iterator>

  


  My Class structure is like this :

  


  public Class Container {

//the custom class FrameProv has a method called nextFrame() which either gives me the next Frame or throws an Exception; 
//FrameProv also uses a FFmpegFrameGrabber to get the next frame with the help of nextFrame() (if this Information is helpful)
   private FrameProv frameprov;
   private Stream frames;

//Contructor
   public Container(FrameProv fp) {
      frameprov = fp;
      FrameItr itr = new FrameItr();
      frames = StreamSupport.stream(Spliterators.spliteratorUnknownSize(itr, Spliterator.ORDERED), false);
   }

   private class FrameItr implements Iterator {

      @Override
      public boolean hasNext() {
         //TODO
      }

      @Override
      public Frame next() {
      //TODO
      }
   }
}


  


  Could anyone help me with the hasNext() methode ? I dont know how I check if there is a next Frame without using the getting the next Frame (which should be returned in next())

  


  I tried using the nextFrame() Methode from FrameProv in hasNext() but hasNext() should never use this methode since it should only check if there is a next Frame.

  avfilter/af_dynaudnorm : fix another clipping with custom peak value
  This always happened at start with alternative boundary mode disabled.
  
  The clipping only occurred if starting samples where high enough.

• What is the Best Approach for Storing and Displaying Video Files as Base64 in HTML for High Performance and Efficiency ? [closed]

  25 août 2023, par Barthez

  I'm currently working on a project where I need to allow users to upload videos, which will then be converted to Base64 and embedded within an HTML file. I'm reaching out to gain a better understanding of the best practices for accomplishing this task while adhering to Stack Overflow guidelines.Here's my plan so far:Video Upload : Users will be able to upload videos through a web interface.Conversion to Base64 : The uploaded video will be converted to Base64 using [specific library/tool].Embedding in HTML : The Base64 encoded video will be embedded within an HTML file using the tag.Before I proceed, I have a few questions:Are there any particular libraries or tools you recommend for converting videos to Base64 efficiently ?What are the potential performance implications of embedding Base64 videos in HTML files, especially considering large video files ?Are there any security concerns I should be aware of when implementing this process ?How can I ensure cross-browser compatibility when embedding these Base64 videos ?Are there any alternatives to this approach that might be more efficient or manageable ?I want to make sure I'm following best practices and avoiding any pitfalls, so any insights, tips would be greatly appreciated. Thank you for your time and assistance !
