Device capability negotiation method and apparatus, and computer storage medium

A method for device capability negotiation, comprising two steps of:

• sending, by a second device, a multi-layer video data request to a first device, wherein the multi-layer video data request comprises:
• capability information possessed by the second device for decoding a multi-layer video bitstream, and/or capability information possessed by the second device for decoding a base layer video bitstream;
• and
• receiving, by the second device, response information which is sent by the first device according to the capability information possessed by the second device, wherein the response information comprises at least one of the following information:
• decoding capability information needed for decoding a multi-layer video bitstream, decoding capability information needed for decoding various layers in the multi-layer video bitstream, and decoding capability information needed for decoding different combinations of output layers in the multi-layer video bitstream wherein the first device is a server and the second device is a terminal, or the first device is a terminal and the second device is another terminal.

An apparatus for device capability negotiation, applied to a first device, comprising a processor and a memory, wherein the memory stores processor-executable programs that cause the processor to perform two steps of:

• receiving a multi-layer video data request sent by a second device, wherein the multi-layer video data request sent by the second device comprises decoding capability information of the second device, wherein the decoding capability information of the second device comprises:
• capability information possessed by the second device for decoding a multi-layer video bitstream, and/or capability information possessed by the second device for decoding a base layer video bitstream;
• and
• sending response information to the second device according to the decoding capability information of the second devices, wherein the response information comprises at least one of the following information:
• decoding capability information needed for decoding a multi-layer video bitstream, decoding capability information needed for decoding various layers in the multi-layer video bitstream, and decoding capability information needed for decoding different combinations of output layers in the multi-layer video bitstream wherein the first device is a server and the second device is a terminal, or the first device is a terminal and the second device is another terminal.
