Embodiment 1

[0044] figure 1 A flow chart of a multi-channel video playback method provided in the first embodiment of the present invention is shown, and the details are as follows:

[0045] Step S101, parsing the video file of the first channel, obtaining the video code stream and audio code stream of the first frame of the video file of the first channel, and obtaining the video code stream and the video code stream of the first frame of the video file of the first channel Attributes of the audio code stream; the attributes of the video code stream and the audio code stream of the first frame of the video file of the first channel include the decoding method and decoding size of the video code stream and the audio code stream.

[0046] Among them, the format of the video file can be Audio Video Interleaved (avi), mp4, wmv, etc.; the attributes of the video code stream and audio code stream refer to the information obtained from the file container, including: the decoding method of the v...

Embodiment 2

[0075] figure 2 It shows a structural diagram of a multi-channel video playback device provided by the second embodiment of the present invention. The multi-channel video playback device can be an mp5, a tablet computer, a network set-top box, etc. For the sake of illustration, only the example related part.

[0076] The multi-channel video playback device includes: a code stream attribute acquisition unit 21 , a code stream attribute setting unit 22 , a register setting unit 23 , a code stream decoding unit 24 , and a code stream playing unit 25 . in:

[0077] The code stream attribute obtaining unit 21 is used to analyze the video file of the first channel, obtain the first frame video code stream and the audio code stream of the video file of the first channel, and obtain the first frame video code stream and the audio code stream of the video file of the first channel. The attributes of a frame of video code stream and audio code stream; the attributes of the first fram...

Abstract

The present invention is adapted to the field of video file playing, and provides a multi-channel video playing method and device. The method includes: A, obtaining attributes of a first frame video code stream and audio code stream of a video file of a first channel; B, obtaining attributes of a first frame video code stream and audio code stream of video files from the second channel to the Nth channel; C, setting a decoding manner and a decoding size of the first channel; D, setting a decoding manner and a decoding size of a corresponding channel; E, setting a register of the first channel; F, setting registers for the second channel to the Nth channel; G, performing hardware decoding on the video files from the first channel to the Nth channel respectively, and performing software decoding at the same time; H, repeating steps E to G until the video files from the first channel to the Nth channel are all decoded; and I, playing the decoded video files. The multi-channel video playing method and device disclosed in embodiments of the present invention can increase the decoding efficiency.

Description

technical field [0001] The invention belongs to the field of video playing, and in particular relates to a multi-channel video playing method and device. Background technique [0002] At present, the video playback technology has been developed to the point where video decoding with multiple resolutions and multiple decoding methods can be formulated according to the needs of users and the configuration of the player. During the video playback process, the pure hardware decoding process, the parsing of the video file to obtain the pure video code stream and audio code stream, and the decoding process of the audio code stream are more time-consuming. [0003] In the traditional video playback method, software is used to analyze the video file, obtain a frame of video code stream and audio code stream of the video file, then perform hardware video decoding, software audio decoding, and finally play the decoded video code stream and audio code stream . Since the existing vide...
