On the Web platform, after creating a stream through the "createStream" method and assigning a value to the "srcObject" of the video object, why is there no video in the video object?

You can handle this in the following two ways:

• You need to set the "autoplay" attribute for the video object to autoplay.
• You can set the "controls" attribute for the video object, and the user can then manually click the playback control to play.
