Systems and methods are disclosed for the rendering of contents communicated between devices. A source device processes a video sequence and transmits it to a target device together with metadata including rendering directives. At the target device, the received video sequence is rendered according to the rendering directives. Rendering is affected by events detected by the target device at the time of rendering or by the target device's information. Transparency masks, generated by the source device, are transmitted in an alpha channel to the target device, and are used for blending the video sequence with a secondary content.

Configuring alpha channel video based on display settings

In some implementations, a computing device can notify a media application when a screen recording may be in progress. For example, the computing device can be configured to send media content provided by the media application for presentation on the display of the computing device to a second destination (e.g., a file, a remote playback device, a remote recording device, etc.) that may result in a recording of the display screen of the computing device. To allow the media application an opportunity to protect the media content from unauthorized recording, the computing device can notify the media application that the media content being sent to the second destination may be recorded. In response to receiving the notification, the media application can modify the presentation of the media content to prevent or downgrade any recording that may be performed.
