VideoStream resource for WebM videos.
VideoStream resource handling the WebM video format with
.webm 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.
Note: 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.
Note: 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
