Problems solved by technology

[0003] Traditional audio and video editing software is based on the C / S architecture. Users need to install client software and maintain software updates. They need to copy audio and video files many times, which causes great inconvenience; thus, online audio and video editing software systems appear. However, these systems have the following defects: first, they can only locate second-level and key frames, but cannot locate non-key frames, and cannot realize accurate editing of audio and video; second, physical space is generated after editing, which increases disk space overhead

Embodiment Construction

[0034] specific implementation plan

[0035] In order to make the purpose, technical method and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] figure 1 Shown is a flow chart of an online audio and video editing method provided by an embodiment of the present invention.

[0037] like figure 1 As shown, first the audio and video object is acquired S10, and the audio and video object to be edited is determined; the audio and video object is transcoded S20, and the duration, bit rate, container format, and other information of the audio and video object are obtained; video encoding format, video encoder, bit Rate, frame rate, number of frames, width, height, pixel format; audio encoding format, encoder, number of channels, sampling rate, bit rate; select an appropriate transcoding strategy based on these metadata, convert it to a for...

Abstract

The invention provides a precise audio-video online virtual editing method comprising the following steps: S10, audio-video object acquiring; S20, audio-video object trans-coding; S30, online editing by a user; S40, audio-video object precise positioning; and S50, editing association. Visual editing is implemented by the steps of embedding an editing tool into a browser, performing precise positioning to frames by use of a streaming media enhanced positioning technology, and associating editing information with a parent video. In addition, the invention provides a precise audio-video online virtual editing system comprising a player and online editing tool module, a streaming media server and audio-video data processing server module and a database module. Thus, precise and efficient online audio-video editing and playing is realized, repeated audio-video storage is avoided, and the effective utilization rate of the storage space is improved.

Description

technical field [0001] The invention relates to the field of network audio and video editing, in particular to an audio and video online virtual editing method and system. Background technique [0002] In the era of big data, multi-modal information is rapidly expanding, especially the amount of audio and video information is increasing rapidly. Therefore, the demand for secondary editing of audio and video information to improve viewing efficiency and facilitate storage and retrieval is becoming more and more urgent. [0003] Traditional audio and video editing software is based on the C / S architecture. Users need to install client software and maintain software updates. They need to copy audio and video files many times, which causes great inconvenience; thus, online audio and video editing software systems appear. However, these systems have the following defects: first, they can only locate second-level and key frames, but cannot locate non-key frames, and cannot realize...
