Video Stream
Description
This component allows you to stream video from media file locally or across a network.
You must provide a valid URL or file path. Width and Height are optional and default to 640 x 480 pixels.
To begin streaming, trigger the Start input. The video arrives as constant stream of bitmaps. If you want to control when a frame comes out of
the component you can set the Manual input to true and use the Grab trigger to get a frame exactly when you want it. This is useful if you
don't want every single frame but maybe need them at a particular time interval or on demand.
You can Step through the video frame by frame by triggering the Step input. Note that this is not the same as manually grabbing a frame.
When stepping the streaming is paused between steps whereas when grabbing frames streaming continues between grabs.
To resume play after stepping trigger the Pause/Play input. This can also be used to pause playback.
Triggering the Stop input will end streaming and you can only resume by re-starting from the beginning.
Most popular image formats are supported including AVI, MPEG, MP4, M4V, WMV, MOV.
