Embodiment Construction

[0064] The present invention will be described in further detail below through specific embodiments and accompanying drawings.

[0065] The core technical solution of the present invention is: preset filter link model and local filter; and when establishing filter link, include:

[0066] A. Select the filter link model, and use the source node of the filter link model as the current node.

[0067] B. According to the filter type of the current node and its key attribute value, select a matching filter from the local filters as the filter of the current node.

[0068] C. Judging whether the next node exists according to the node relationship of the current filter link model, if it exists, take the next node as the current node, and return to step B, otherwise the filter link is established successfully.

[0069] The present invention adopts the mechanism of combining the filter link model and the local filter. The so-called filter link model refers to the combination of a ser...

Abstract

The invention discloses a filter link establishing method for a media file and a device thereof. A filter link model and a local filter are arranged by the method in advance; and moreover, the establishment of the filter link includes steps that: A. the filter link model is selected, and a source node of the filter link model is taken as a current node; B. a matching filter is selected from the local filter according to the filter type and the key attribute value of the current node and taken as a filter of the current node; C. a judgment on whether a next node exists or not is made accordingto the node relations of the current filter link model, and if the next node exists, the next node is taken as the current node, and the step B is then conducted; otherwise, the filter link establishment process is finished. The corresponding device of the invention comprises an arranging module, a model selecting module, a filter selecting module and a judging module, which respectively conduct the steps of the method. By adopting the method and the device of the invention, the connection speed of the filter can be improved, and the stability and the playing efficiency of media playing are improved.

Description

technical field [0001] The invention relates to the technical field of media data processing, in particular to a method and device for establishing a filter link of a media file. Background technique [0002] Currently, media files usually contain three formats, which are file container format, video format and audio format. But the media file of pure video does not include the audio format, similarly, the media file of pure audio does not include the video format. [0003] The function of the file container format is to specify the storage rules of video data and audio data in the media file. The file container format usually corresponds to the extension of the media file. The common file container formats are: avi, asf, real, mpeg 1, mpeg2, mpeg4, mp3, mov, flv, mkv, etc. [0004] The video format specifies the compression standard of video data. Common video formats include: H.26x series formats (such as h.261, h.263, h.264), MPEG series formats (such as mpeg1 video, mp...
