Working with Multimedia Files

You have now manipulated y our video stream and exported it from a Simulink

model to a multimedia file. For more information, see the To Multi media File

block reference page in the Video and Image Processing Blockset Reference.

Working with Audio

In this example, you u se the From Multimedia File block to import a video

stream into a S imulink mode l. You also use Signal Process in g Blockset From

Wave File block to import an audio stream into the model. Then you write

this audio and video to a single file using the To Multimedia File block.

This procedure assumes you are working on a Windows platform:

1 Create a new Simulink model, and add to it the blocks shown in the

following table.

2 Connect the blocks so your model look s similar to the following figure.
