Abstract: Aspects of the subject technology relate to encoding of video frames having content with a variable resolution that varies within the video frame. Aspects of the subject technology can provide an efficient encoding by using smaller macroblocks for lower resolution content within the video frame, and larger macroblocks for higher resolution content within the video frame. An encoder may be provided with resolution information for the content of the video frame, which can be used by the encoder to determine macroblock sizes, macroblock divisions, and/or prediction modes for the encoding of the video frame.

Abstract: The subject technology provides a framework for privacy-protecting mixed reality and/or virtual reality recordings and/or for providing mixed and/or virtual reality video streams for display on external devices. A first process on an electronic device can receive, from a second process on the electronic device, a frame of a video stream. In some aspects, the frame includes an indicator of privacy-sensitive content The first process can obfuscate at least a portion of the frame based at least in part on the indicator of the privacy-sensitive content. The first process can provide the obfuscated at least the portion of the frame for at least one of: inclusion in a recorded video or for on stream display another electronic device.
