Abstract
The invention provides a multi-process decoding playing method and device, the method and device are applied to a client, the client is provided with a main process and a plurality of sub-processes, the sub-processes comprise Libvlc players, and the method comprises the following steps: obtaining a selection mode of a user; creating a main window on the main process according to the selection mode; a plurality of sub-windows are generated on the main window, and each sub-process corresponds to the corresponding sub-window; drawing the corresponding video stream on each sub-window to obtain a plurality of drawn video streams; performing demultiplexing and decoding on the plurality of drawn video streams through a Libvlc player to obtain a plurality of decoded video streams; displaying the plurality of decoded video streams; the multi-process player is used for playing, so that simultaneous playing of multiple paths of programs and long-time playing of multiple players can be met, and independence and stability are improved.
Description
technical field [0001] The invention relates to the technical field of video processing, in particular to a multi-process decoding and playing method and device. Background technique [0002] At present, video playback is played by a single-process player, which cannot satisfy the simultaneous playback of multiple programs; when multiple single-process players play for a long time, there will be crashes, stoppages, freezes, or jumps to Other frame interface and other issues. [0003] In addition, with the complexity of business logic and the increase of requirements, single-process players cannot meet the iterative requirements of products. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a multi-process decoding and playing method and device, which uses a multi-process player to play, which can satisfy the simultaneous playback of multiple programs and the long-term playback of multiple players, improving independence...
