Systems and methods of video forwarding with adaptive video transcoding capabilities

A method of providing real-time adaptive video transcoding in a selective forwarding unit (SFU), comprising:

• receiving a plurality of video streams from a plurality of user devices, respectively, one or more of the plurality of video streams corresponding to one or more large video streams;
• determining an available bandwidth to each of the plurality of user devices;
• identifying one or more user devices among the plurality of user devices as being associated with a low available bandwidth;
• performing, in real-time, adaptive video transcoding on a large video stream among the one or more large video streams to produce a corresponding small video stream that conforms to the low available bandwidth;
• and
• selectively forwarding at least the corresponding small video stream to the one or more user devices associated with the low available bandwidth.

A selective forwarding unit (SFU), comprising:

• a real-time adaptive video transcoder;
• a memory storing one or more sets of instructions;
• and
• at least one processor configured to execute the one or more sets of instructions:
• to receive a plurality of video streams from a plurality of user devices, respectively, one or more video streams among the plurality of video streams having a large frame format;
• to obtain a display resolution of each of the plurality of user devices;
• to identify one or more user devices among the plurality of user devices as having a low display resolution;
• to cause the real-time adaptive video transcoder to perform, in real-time, frame resolution adaptation on a respective video stream among the one or more video streams having the large frame format to transfonn the respective video stream to a corresponding video stream having a reduced frame format that conforms to the low display resolution;
• and
• to selectively forward at least the corresponding video stream having the reduced frame format to the one or more user devices having the low display resolution.
