Embodiment Construction

[0056] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] like figure 1 As shown in the figure, the mainstream audio and video encoder in the market currently has a large market share of h264. Popular formats such as avi, mp4, flv, mkv, m2ts and other formats all support this audio and video encoding format. In the traditional conversion process, the encoding speed of 1080p audio and video is often only about 100 frames, and an hour of audio and video single The conversion takes 20 ...

Abstract

The invention discloses a multi-mode audio and video format high-speed conversion method and system, comprising the following steps: Step S1, the conversion system obtains target audio and video files and target conversion formats, and performs audio and video encoder conversion according to the target conversion formats. The matching search obtains the audio and video encoder that supports the target conversion format as the target encoder; the conversion system selects the conversion mode according to the matching state of the target encoder and the target conversion format, and performs the target audio and video files according to the selected conversion mode. Format conversion, so as to provide switching selection of multiple conversion modes for the target audio and video files, and improve the success rate of converting the target audio and video files into the target format. The present invention provides switching options of various conversion modes, and the format conversion has high versatility and strong compatibility, so that the success rate of converting the target audio and video files into the target format is greatly improved, and the conversion speed is greatly improved.

Description

technical field [0001] The invention relates to the technical field of audio and video format conversion, in particular to a multi-mode audio and video format high-speed conversion method and system. Background technique [0002] When playing audio and video, the audio and video source device sends the audio and video to be played to the playback device, such as a set-top box, etc., and the playback device sends the received audio and video to the display through the high definition multimedia interface (HDMI) interface. For example, televisions, projectors, etc., and then the received audio and video are played by the display. [0003] At present, there are mainly two types of audio and video formats supported by monitors with HDMI interface, one is standard dynamic range (SDR) audio and video formats, and SDR audio and video formats include a variety of SDR audio and video formats, such as , according to different color gamuts, SDR audio and video formats include BT601 au...
