Class VisualSampleEntry

  • All Implemented Interfaces:
    Box, SampleEntry, Container, ParsableBox
    public final class VisualSampleEntry
extends AbstractSampleEntry
implements Container

    4cc = ""mp4v"" || ""s263"" || ""avc1"" || ""avc3"" || ""drmi""

    Contains information common to all visual tracks. 
     class VisualSampleEntry(codingname) extends AbstractSampleEntry (codingname){
  unsigned int(16) pre_defined = 0;
  const unsigned int(16) reserved = 0;
  unsigned int(32)[3] pre_defined = 0;

 }

    Format-specific information is appened as boxes after the data described in ISO/IEC 14496-12 chapter 8.16.2.

        public void parse​(ReadableByteChannel dataSource,
                  ByteBuffer header,
                  long contentSize,
                  BoxParser boxParser)
           throws IOException
        Description copied from interface: ParsableBox
        Parses the box excluding the already parsed header (size, 4cc, [long-size], [user-type]). The remaining size of the box is the contentSize, contentSize number of bytes should be read from the box source (readableByteChannel). If you need the header buffer at a later stage you have to create a copy.
        Specified by:
        parse in interface ParsableBox
        Specified by:
        parse in class AbstractSampleEntry
        Parameters:
        dataSource - the source for this box
        header - the box' already parsed header (create copy if you need it later as it will be overwritten)
        contentSize - remaining bytes of this box
        boxParser - use it to parse sub-boxes.
        Throws:
        IOException - in case of an error during a read operation

      • getBox

        public void getBox​(WritableByteChannel writableByteChannel)
            throws IOException
        Description copied from interface: Box
        Writes the complete box - size | 4-cc | content - to the given writableByteChannel.
        Specified by:
        getBox in interface Box
        Specified by:
        getBox in class AbstractSampleEntry
        Parameters:
        writableByteChannel - the box's sink
        Throws:
        IOException - in case of problems with the Channel
