The present invention provides a method, device and computer-readable medium of a seamless and dynamic switch between resolutions based on hardware decoding and belongs to a field of the internet technology. According to the method, device and computer-readable medium of the present invention, during a DASH video playback, when it needs to switch to another resolution, the original decoder continues to decode the video stream in the original encoded format that already stores in a buffer, while the video stream in the original encoded format is decoded, a second decoder corresponding to a target encoded format is initialized based on a video stream in the target encoded format received by the original decoder, and the video stream of the target encoded format is decoded by the second decoder, so as to realize the seamless switch between resolutions, avoid a jam in the process of playing the video, and improve the user experience.

Seamless switching method, device and storage medium of hardware decoding dynamic resolution

This application provides techniques for establishing a P2P connection. The techniques comprise communicating with at least two auxiliary nodes to obtain answer messages returned by the at least two auxiliary nodes; determining, based on the answer messages, at least one public network address corresponding to an internal network address of a first client device; registering, with a cloud server, the at least one public network address corresponding to the internal network address of the first client device, and monitoring the at least one public network address corresponding to the internal network address of the first client device; and establishing a P2P connection to a second client device when detecting, in a preset duration, that the second client device returns a response data packet to a target public network address.

Method, client, and system for establishing P2P connection

This application provides techniques comprising S: establishing a queue for accommodating m file descriptors for creating nfirst access request data packets; S: creating an ifile descriptor in the queue, sending an ifirst access request data packet by using the ifile descriptor, and monitoring a source port recorded by the ifile descriptor; S: at every first preset time interval t, enabling i to automatically increase by 1, continuing to perform operation S, and setting preset monitoring time T for each source port, where T=t*m; and S: ending monitoring of an (i−m)source port and destroying a corresponding file descriptor while creating an ifile descriptor in the queue when m*j<i≤m*(j+1), and stopping monitoring of other source ports in response to detecting that a first port receives a response data packet, where the first port is any source port in a monitored state.

Data sending method and apparatus, and method and system for establishing P2P connection

The present invention provides a method, device and computer-readable medium of a seamless switch between resolutions based on software and hardware decoding and belongs to a field of the Internet technology. The method, device and computer-readable medium of the present invention comprise, during playing a DASH video, initializing a software decoder according to a video stream in a target encoded format received by an original decoder when it needs to switch to another resolution, at the same time the original decoder continuing to decode the video stream in an original encoded format existing in a buffer, decoding the video stream in the target encoded format using the software decoder after the video stream in the original encoded format is decoded, at the same time initializing a second hardware decoder corresponding to the target encoded format, switching to the second hardware decoder and stopping software decoding when a decoding progress of the second hardware decoder catches up with a decoding progress of the software decoder, so as to realize the seamless switch between the resolutions, avoid sticking in the process of playing the video, and improve user experience.
