To display the video in a zone, SetRectangle must be called. EnableZoneSupport must be called to use the zones

functionality.

MPEG2 video files are encoded with a specific aspect ratio, and output display resolutions have an aspect ratio. Video

display modes 1 and 2 use these aspect ratios to ensure that the video-file aspect ratio is preserved when it is displayed.

This will fail only when a widescreen monitor displays a 4:3 output resolution such as 800x600 across the whole screen

(i.e. the monitor does not respect the aspect ratio). Please note that this feature relies on the correct aspect ratio marking

of the MPEG2 video files. Unfortunately, not all files are marked correctly.

Users can add events that trigger messages of the roVideoEvent Timecode Hit at the specified millisecond times in a

video file. The data field of the roVideoEvent holds the user data passed in with AddEvent().

Example: This script uses timecode events. The script prints out 2, 5, and 10 into the video at 2 seconds, 5 seconds, and

10 seconds. The msg is approaching frame accurate.

10 v = CreateObject("roVideoPlayer")

20 p = CreateObject("roMessagePort")

30 v.SetPort(p)

40 ok = v.AddEvent(2, 2000) ' Add timed events to video

50 ok = v.AddEvent(5, 5000)

60 ok = v.AddEvent(10, 10000)

70 ok = v.AddEvent(100, 100000)

80 ok = v.PlayFile("SD:/C5_d5_phil.vob")

90 msg = Wait(0,p) ' Wait for all events

95 if msg.GetInt() = 8 then stop ' End of file

100 if msg.GetInt() <> 12 goto 90 ' I only care about time events
