Video and audio events are declared as separate classes. Events can have one of the following values, which are retrieved using the GetInt() method:
3 |
| The current media item has started playing. |
8 |
| The media item has completed playback. |
12 |
| A particular timecode has been reached. See the entry on Timecode Events for more details. |
13 |
| An roAudioPlayerMx instance has begun playback of an audio file. |
14 |
| An roAudioPlayerMx instance has completed playback of an audio file. |
15 |
| The EventTimeStamp of an roAudioPlayerMx instance has been been reached. |
16 |
| A media error has been detected. As opposed to code 30, this event usually indicates transient errors (e.g. low buffer levels). |
17 |
| A media error has been detected during roAudioPlayerMx playback. |
18 |
| The current media item has completed fading out. See the roVideoPlayer.SetFade() entry for more details. |
19 |
| |
20 |
| The FadeOutLocation of an roAudioPlayerMx instance has been reached. |
21 |
| |
26 |
| The stream seems to be underflowing. This event usually indicates that the streaming latency is set too low. It will be generated every few seconds as long as underflow is detected. |
| 30 | MediaError_NotStarted | A fatal error has been encountered while attempting to start playback (e.g. the video format is not supported). |
Note
The Diagnostic Web Server log may return more specific information about media error states.
ifInt
The ifInt interface contains the event ID enumerated above and provides the following:
GetInt() As Integer
Returns the integer value of the object.
SetInt(value As Integer) As Void
Sets the integer value of the object.
GetSourceIdentity() As Integer
SetSourceIdentity() As Integer
ifData
The ifData interface contains userdata and provides the following:
GetData() As Integer
SetData(a As Integer)
Example

if escm and msg=BM then retcode=1:return
if esc1 and msg=B1 then retcode=2:return
if esc2 and msg=B2 then retcode=3:return
if esc3 and msg=B3 then retcode=4:return
else if type(msg)="rotINT32" then
