Abstract
A device capability negotiation method includes receiving, by a first device, a multilayer video data request sent by a second device, and sending, by the first device, response information to the second device. The response information includes at least one of the following information types: decoding capability information needed for decoding a multilayer video code stream, decoding capability information needed for decoding various layers in the multilayer video code stream, and decoding capability information needed for decoding different output layer combinations in the multilayer video code stream. Also disclosed are a device capability negotiation apparatus, and a computer storage medium.
