actionscript3-跟踪操作以获取有关FLV视频中提示点的信息

Posted 2021-02-26

this is a handy snippet to trace the info about any cuepoints actionscript encounters, embedded in a FLV [flash video]. these traces will display the name, type and time of the cuepoint - in a nicely formatted list

/* ||||||||||||||||| CUEPOINT TRACES ||||||||||||||||||||
these trace actions are handy for returning the info that flash has about any cuepoints it encounters, embedded in an FLV [flash video] file. put these traces inside a cuepoint listener function to test whether flash is picking up the cuepoints in the first place, before you add any more complicated code.  these traces will display:
 
- the 'event' the listener has detected [ie. a cuepoint]
- the name of the cuepoint
- the type of the cuepoint [ie. 'event' or 'navigation']
- the time the cuepoint sits at in the video
 
[note: this code assumes your FLV video file has an instance name of 'vid'.  if you change the instance name change the "this.vid.playheadTime" part of the code accordingly]
 
this is the same trace code i demo'd in class.  i've just tidied it up a bit by adding in a few tabs [	] and a linebreak [
]at the end, so it formats up neater.  i cannae help it - i'm just such a perfectionist!

trace("listener detected: 	"+event.type);
trace("cuepoint is called: 	"+event.info.name);
trace("cuepoint is of type: 	"+event.info.type);
trace("vid playhead time: 	"+this.vid.playheadTime);
trace("------

// end traces
