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 <ref> 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".
