	</brief_description>
	<description>
		[VideoStream] resource handling the [url=https://www.webmproject.org/]WebM[/url] video format with [code].webm[/code] extension. Both the VP8 and VP9 codecs are supported. The VP8 and VP9 codecs are more efficient than [VideoStreamTheora], but they require more CPU resources to decode (especially VP9). Both the VP8 and VP9 codecs are decoded on the CPU.
		[b]Note:[/b] Alpha channel (also known as transparency) is not supported. The video will always appear to have a black background, even if it originally contains an alpha channel.
		[b]Note:[/b] There are known bugs and performance issues with WebM video playback in Godot. If you run into problems, try using the Ogg Theora format instead: [VideoStreamTheora]
