Embodiment Construction

[0045]Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended to limit the scope of the application. The scope of protection of this application should be defined by the appended claims.

[0046] Such as figure 1 As shown, it is a multi-segment media ...

Abstract

The invention discloses a multi-segment media file cross-segment playing method. A media file comprises a first segment, at least one intermediate segment and a second segment. The multi-segment media file cross-segment playing method comprises steps that, cross-segment seek to the second segment is carried out in a playing process of the first segment, downloading and de-multiplexing of the first segment stop, start states of a decoding module and a rendering module are kept, and decoding cache and rendering cache of the decoding module and the rendering module for the first segment are cleared; downloading and de-multiplexing of the second segment start, after head information parsing for the second segment is accomplished, audio and video packet de-multiplexing for the second segment is carried out, the data packet acquired through de-multiplexing is put to the decoding module and the rendering module to start corresponding decoding and rendering; splicing processing on a time stamp at the cross-segment seek operation connection portion of the first segment and the second segment is carried out. Through the method, cross-segment playing fluency is improved, and user watch experience is improved.

Description

technical field [0001] The present invention relates to a media file playing method and system, in particular to a multi-segment media file cross-segment playing method and system. Background technique [0002] The mobile streaming media service based on the open Internet is one of the best solutions to meet the needs of many applications such as live broadcast, on-demand and time-shifting in the future. Based on the audio and video services of the open Internet, the terminals can be TVs, computers, set-top boxes, PADs, smart phones, etc. It means providing services on the network, emphasizing the independence of services from physical networks. For the media content provided by major audio and video websites, most of the media content is stored and transmitted by dividing time into multiple segments (for example: a 90-minute movie can be divided into 9 segments, 10 minutes per segment), each segment of which is an independent and complete media file. [0003] Current mul...
