Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] As mentioned above, due to the link established by using the enumerated media type, there are often problems such as failure to play normally, such as no image, no sound, or out-of-sync image and sound. The reason for these problems is that the implementation mechanisms of filters are different, and the efficiency is also different. Moreover, when using enumerated media types to establish a connection, it is necessary for the two filters to inquire whet...

Abstract

The invention provides an establishment method and devices of a playback link and a player. The establishment method comprises acquiring audio and video files according to a received file path, acquiring the document type and the encoding type of the audio and video files according to the audio and video files, choosing a resolver, a decoder and a renderer according to the document type and the encoding type of the audio and video files, and establishing a playback link to play the audio and video files according to the chosen resolver, the decoder and the renderer. Through the establishment method and the devices of the playback link and the player, the establishment of a link and the optimization of playing effect can be achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and player for establishing a play link. Background technique [0002] For the player based on DirectShow technology, its playback core is to realize the establishment of the playback link (parser->decoder->renderer) by enumerating the filters installed in the system, where the filter includes the parser (filter) , decoder (decoder) and renderer (render), parser, decoder and renderer can be regarded as rendering links. This connection method using the principle of handshake between filters is not only inefficient, but even if the link is successfully established, there may be situations such as failure to play or low playback efficiency. Contents of the invention [0003] The main purpose of the embodiments of the present invention is to provide a method, device and player for establishing a play link, so as to solve the problem of low efficiency of est...
