Abstract:
A method includes sending, by a first device, a first message to a second device, sending a third message to the second device, where the first message includes information about at least one media capture capability supported by the first device, and at least one first association identifier, the third message includes at least one configuration item supported by the first device and at least one second association identifier, and the at least one first association identifier corresponds to the at least one second association identifier in a one-to-one manner, and receiving, a second message and a fourth message sent by the second device, where the second message includes at least one media capture capability that is selected by the second device according to the first message and the third message, and at least one third association identifier corresponding to the at least one media capture capability.
Abstract:
A method and system for controlling multiple auxiliary streams, a control device, and a node, which implements sending and receiving of multiple auxiliary streams of multiple nodes. The method includes determining, by a control device, to allocate a token to m auxiliary streams, where the m auxiliary streams belong to n node or nodes, n≧1, m≧2, and m≧n, allocating a token to the m auxiliary streams, sending a token allocated to an auxiliary stream of a first node to the first node, where the first node is one node of the n node or nodes, and sending a first indication message to the first node, where the first indication message is used to instruct the first node to send a first auxiliary stream according to the received token, and the first auxiliary stream includes at least one auxiliary stream of the m auxiliary streams.
Abstract:
The present invention provides a media negotiation method, device, and system for a multi-stream conference. The method includes: sending a media advertisement message that carries information about at least two media data objects; receiving a media selection message that carries information, about a media data object, selected by a second media entity; and determining a corresponding media data object according to the information, about the media data object, selected by the second media entity, and establishing a media transmission channel with the second media entity, so as to transmit the corresponding media data object to the second media entity through the media transmission channel. In embodiments of the present invention, more media data streams can be represented, and the representation accuracy and the amount of information of the media data stream can be improved
Abstract:
A method for adjusting media stream transmission bandwidth and a related apparatus are provided. A media stream sending end acquires scores that are given, according to identifiers of multiple media streams, by a media stream receiving end to the media streams, where the multiple media streams are transmitted at a same transmission port, and these identifiers are described based on media stream content; when it is detected that congestion occurs or congestion is resolved, the media stream sending end performs transmission bandwidth adjustment on a corresponding media stream according to these scores, and therefore media stream transmission bandwidth adjustment may be performed, based on the media stream content, on the multiple media streams transmitted at the same transmission port.
Abstract:
An image rendering method and apparatus where the method includes recognizing a target area from a to-be-rendered image, setting a virtual light source for the target area, and performing rendering on the target area using the virtual light source. When rendering is performed on the to-be-rendered image, the rendering performed on the to-be-rendered image is implemented using the virtual light source. The virtual light source plays a rendering action only on the target area corresponding to the virtual light source, and does not affect another part of the to-be-rendered image, and therefore an image effect of the to-be-rendered image may be relatively good.
