Using the information object
The following table shows the possible values for video metadata that are passed to the onMetaData() callback
function in the Object that they receive:
Parameter Description
aacaot AAC audio object type; 0, 1, or 2 are supported.
avclevel AVC IDC level number such as 10, 11, 20, 21, and so on.
avcprofile AVC profile number such as 55, 77, 100, and so on.
audiocodecid A string that indicates the audio codec (code/decode technique) that was used - for example “.Mp3” or “mp4a”
audiodatarate A number that indicates the rate at which audio was encoded, in kilobytes per second.
audiodelay A number that indicates what time in the FLV file "time 0" of the original FLV file exists. The video content
needs to be delayed by a small amount to properly synchronize the audio.
canSeekToEnd A Boolean value that is true if the FLV file is encoded with a keyframe on the last frame, which allows seeking
to the end of a progressive -download video file. It is false if the FLV file is not encoded with a keyframe on
the last frame.
cuePoints An array of objects, one for each cue point embedded in the FLV file. Value is undefined if the FLV file does not
contain any cue points. Each object has the following properties:
type: a string that specifies the type of cue point as either "navigation" or "event".
name: a string that is the name of the cue point.
time: a number that is the time of the cue point in seconds with a precision of three decimal places
(milliseconds).
parameters: an optional object that has name-value pairs that are designated by the user when creating
the cue points.
duration A number that specifies the duration of the video file, in seconds.
framerate A number that is the frame rate of the FLV file.
height A number that is the height of the FLV file, in pixels.
seekpoints An array that lists the available keyframes as timestamps in milliseconds. Optional.
tags An array of key-value pairs that represent the information in the “ilst” atom, which is the equivalent of ID3 tags
for MP4 files. iTunes uses these tags. Can be used to display artwork, if available.
trackinfo Object that provides information on all the tracks in the MP4 file, including their sample description ID.
videocodecid A string that is the codec version that was used to encode the video. - for example, “avc1” or “VP6F”
