A-SMIL players may support showing video from external source if the appropriate hardware is available. To display the video content, play it using a <video> whose source is "adapi:capture".
Composite Video Source
The following code shows how to display video sourced from the composite video capture hardware.
<video src="adapi:capture"> <param name="adapi:videoInput" value="composite" /> </video>
The video input media item can be placed in a playlist and used similar to the video object (see SMIL Media Objects).
Several parameters are available when displaying from the composite video source.
- adapi:videoInput: must be "composite" for the composite video source
- adapi:videoFormat: encoding format of the video source. Can be one of the following values: auto (auto detection), NTSC_M, NTSC_M_Japan, PAL_BG, PAL_M, PAL_N, PAL_Nc. If unspecified, default value is "auto".
- adapi:videoAspectRatio: display aspect ratio the video source. Can be one of the following values: auto (auto detection), 4:3, 16:9. If unspecified, default value is "auto".
Built-in Camera
The following code shows how to display video sourced from the device's built-in camera.
<video src="adapi:capture"> <param name="adapi:videoInput" value="camera" /> </video>
The video input media item can be placed in a playlist and used similar to the video object (see SMIL Media Objects).
