/**
 * Cue point is metadata marker used to control and accompany video playback with client-side application events. 
 * Each cue point have at least one attribute, timestamp. Timestamp specifies position of cue point in FLV file.
 * 
* Cue points are usually used as event triggers down video flow or navigation points in a file. Cue points are of two types: *
    *
  • Embedded into FLV or SWF
  • *
  • External, or added on fly (e.g. with FLVPlayback component or ActionScript) on both server-side and client-side.
  • *
*
* To add cue point trigger event listener at client-side in Flex/Flash application, use NetStream.onCuePoint event handler. * * @author The Red5 Project * @author Dominick Accattato ([email protected]) * @author Luke Hubbard, Codegent Ltd ([email protected]) * @param key type * @param value type */ public class MetaCue extends HashMap implements IMetaCue { private static final long serialVersionUID = -1769771340654996861L; /** * CuePoint constructor */ public MetaCue() { } /** * {@inheritDoc} */ @Override public void setName(String name) { this.put("name", name); } /** * {@inheritDoc} */ @Override public String getName() { return (String) this.get("name"); } /** * {@inheritDoc} */ @Override public void setType(String type) { this.put("type", type); } /** * {@inheritDoc} */ @Override public String getType() { return (String) this.get("type"); } /** * {@inheritDoc} */ @Override public void setTime(double d) { this.put("time", d); } /** * {@inheritDoc} */ @Override public double getTime() { return (Double) this.get("time"); } /** {@inheritDoc} */ @Override public int compareTo(Object arg0) { MetaCue cp = (MetaCue) arg0; double cpTime = cp.getTime(); double thisTime = this.getTime(); if (cpTime > thisTime) { return -1; } else if (cpTime < thisTime) { return 1; } return 0; } /** {@inheritDoc} */ @Override public String toString() { StringBuilder sb = new StringBuilder("MetaCue{"); for (Map.Entry entry : entrySet()) { sb.append(entry.getKey().toLowerCase()); sb.append('='); sb.append(entry.getValue()); } sb.append('}'); return sb.toString(); } }
