Methods and systems provide for low lighting adjustments within a video communication session. First, the system receives video content within a video communication session of a video communication platform, the video content having multiple video frames. The system then receives or generates a lighting adjustment request including a lighting adjustment depth, then detects an amount of lighting in the video content. The system then modifies the video content to adjust the amount of lighting, wherein the amount of adjustment of lighting corresponds to the adjustment depth, and wherein adjusting the amount of lighting is performed in real time or substantially real time upon receiving the lighting adjustment request.

A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.

The present disclosure provides a forward multiple-hypothesis encoding/decoding method of an image block. In this method, motion information of a current block including two forward reference frame indexes and two motion vectors are selectively encoded into a bit-stream based on a current encoding mode. The motion information which is not encoded into the bit-stream is derived at a decoder by a predefined rule. This method sufficiently utilizes correlation within motion information of an image block and correlation between the motion information of the current image block and that of an adjacent image block.
