Embodiment 1

[0046] figure 1 It shows a flow chart of a video playback method provided by the first embodiment of the present invention. In this embodiment, the "first" of the first channel and the "second" of the second channel are only used to distinguish two different There is no sequential meaning of the channels, and the details are as follows:

[0047] 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 type and the size of the decoded image of the video code stream and the audio code stream.

[0048] Among them, the format of the video file can be Audio Video Interleaved...

Embodiment 2

[0075] figure 2 It shows a structural diagram of a video playback terminal provided by the second embodiment of the present invention. The video playback terminal can be an mp5, a tablet computer, a network set-top box, etc. For the convenience of description, only the parts related to this embodiment are shown .

[0076] The video playback terminal includes: a first code stream attribute acquisition unit 21, a second code stream attribute acquisition unit 22, a first channel attribute setting unit 23, a second channel attribute setting unit 24, a first video file decoding unit 25, a second Video file decoding unit 26, video file playing unit 27. in:

[0077] The first code stream attribute acquisition unit 21 is used to analyze the video file of the first channel, obtain the first frame video code stream and audio code stream of the video file of the first channel, and obtain the video file of the first channel Attributes of the video stream and audio stream of the first ...

Abstract

The invention is suitable for the field of audio file playing, and provides a video playing method and a terminal thereof. The video playing method comprises the steps of: A. obtaining video code stream attribute of a first channel; B. obtaining video code stream attribute of a second channel; C. setting the attribute of the first channel; D. setting the attribute of the second channel; E. determining a decoding parameter of the first channel, setting the decoding parameter of the first channel in a register of the first channel, and simultaneously decoding a former video code stream and an audio code stream of the first channel; F. determining a decoding parameter of the second channel, setting the decoding parameter of the second channel in a register of the second channel, and simultaneously decoding the former video code stream and audio code stream of the second channel; repeating E and F until the video files of the first channel and the second channel are totally decoded; and G playing the decoded audio files. The video playing method according to an embodiment provided by the invention can improve decoding speed for the video files.

Description

technical field [0001] The invention belongs to the field of video playing, and in particular relates to a video playing method and a terminal. Background technique [0002] Video playback technology is developing rapidly, and video playback has gradually developed from single-channel playback to dual-channel and multi-channel playback. Two video files can be played at the same time, two different video programs can be watched at the same time, and the function of picture-in-picture can also be realized. . [0003] The existing video playback methods usually adopt the following methods when playing two-way video: (1) open the first decoding instance for hardware decoding, and then perform software decoding; (2) open the second decoding instance for hardware decoding, Then perform software decoding; (3) execute (1) and (2) in a loop until the decoding of the video file is completed and then play the decoded video file. Since the existing method parses the video file after h...
