roVideoEvent, roAudioEvent

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	`Playing`	The current media item has started playing.
8	`MediaEnded`	The media item has completed playback.
12	`TimeHit`	A particular timecode has been reached. See the entry on Timecode Events for more details.
13	`Overlay_Playing`	An roAudioPlayerMx instance has begun playback of an audio file.
14	`Overlay_MediaEnded`	An roAudioPlayerMx instance has completed playback of an audio file.
15	`Overlay_TimeHit`	The EventTimeStamp of an roAudioPlayerMx instance has been been reached.
16	`MediaError`	A media error has been detected. As opposed to code 30, this event usually indicates transient errors (e.g. low buffer levels).
17	`Overlay_MediaError`	A media error has been detected during roAudioPlayerMx playback.
18	`FadingOut`	The current media item has completed fading out. See the roVideoPlayer.SetFade() entry for more details.
19	`DecoderEOS`
20	`Overlay_FadingOut`	The FadeOutLocation of an roAudioPlayerMx instance has been reached.
21	`Overlay_DecoderEOS`
26	`Underflow`	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).
	`ResourceShortage`	You are trying to play more video simultaneously than is allowed. If you are playing a single video by creating new video tags, reuse the existing video tag when possible to avoid race conditions when a video tag might hold onto a hardware video resource or take too long to disassociate a video player from the video tag.

The Diagnostic Web Server log may return more specific information about media error states.

ifInt

GetInt() As Integer

Returns the event ID as an integer value.

SetInt(value As Integer) As Void

Sets the integer value.

ifUserData

SetUserData(user_data As Object) As Void

Sets the user data.

GetUserData() As Object

Returns the user data that has previously been set via SetUserData() (on either the event or source object). It will return Invalid if no data has been set.

ifSourceIdentity

GetSourceIdentity() As Integer

SetSourceIdentity() As Integer

The ifSourceIdentity interface has been deprecated. We recommend using the ifUserData interface instead.

ifData

GetData() As Integer

SetData(a As Integer)

Example

vp_msg_loop:
    msg=Wait(tiut, p)    
    if type(msg)="roVideoEvent" then
        if debug then print "Video Event";msg.GetInt()
        if msg.GetInt() = 8 then
            if debug then print "VideoFinished"
            retcode=5
            return
        endif
    else if type(msg)="roGpioButton" then
        if debug then print "Button Press";msg
        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
        if debug then print "TimeOut"
        retcode=6
        return
    endif
