Problems solved by technology

Since there are many types of each module, for example, there are more than 20 types of demux modules, and more than 40 types of decoder modules, so during video playback, if you want to choose to create a certain module, you need to traverse the module Therefore, the video playback process traversal time and decoding time are too long, and the system CPU consumption is too high, which will cause the playback startup to be too slow, which will take longer to start the video playback

Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The present invention provides a method for starting and playing a video, referring to figure 1 , In one embodiment, the method for starting playback based on video includes the following steps:

[0048] Step S101, creating a video sample pipeline;

[0049]In the present embodiment, the present invention provides a kind of video starting and playing method based on Gstreamer player, wherein GStreamer is the open source multimedia frame that is used to construct streaming media application under GNOME desktop environment, and its goal is to simplify the development of audio / video application program , has been able to be used to process multimedia data in various formats such as MP3, Ogg, MPEG1, MPEG2, AVI, and Quicktime. Utilize common videos, extract corresponding video parameters from them, and create diffe...

Abstract

The present invention discloses a video starting playing method which comprises a step of creating a video sample pipeline, a step of obtaining video data, analyzing the video data and extracting parameter information, a step of selecting a corresponding target pipeline from the video sample pipeline according to the parameter information, and a step of sending the video data transmitted by the target pipeline to a client to start the playing of a video. The invention also discloses a video starting device. The invention provides the video starting playing method and the video starting device, the video starting playing time based on a Gstreamer player can be shortened, the memory space of the video is reduced, the computational complexity is reduced, and thus the visual experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video-based start-up playback method and a video start-up device. Background technique [0002] Gstreamer player usually uses pipeline (pipeline) to play video files, and pipeline is composed of source (source) module, demux (demultiplexing) module, decoder (decoding) module and render (output) module. The sequence of the video file playback process is that the source module first uses typefind to search for the demux module, then the demux module uses typefind to search for the decoder module, and finally the decoder module uses typefind to search for the render module, so it is necessary to continuously use typefind to search for the corresponding module, and after the establishment is complete The video can only be played after the pipeline. In this way, when the pipeline is used to play video files, the pipeline pipeline is not established before the video is play...
