The invention has the beneficial effects that: the video file can be generated quickly based on the cloud, and can be conveniently and quickly shared in transmission.
Description
Technical Field
The invention relates to the technical field of video processing, in particular to a video editing method based on a cloud.
Background
The existing video editing function is basically edited based on a mobile phone or a computer client, and the main problems are as follows: the generated video after being clipped needs to be re-encoded, which is slow, and generally waits for the time of x1.5 times of the video duration, so that the generated video is troublesome to share.
Disclosure of Invention
Aiming at the defects of the prior art, the method and the device can rapidly clip and share the video in a cloud clipping mode and a video slicing mode. The technical scheme is as follows.
A video clipping method based on cloud comprises the following steps:
a user side uploads materials to a background server through a system page;
a user carries out operations such as clipping, arranging and the like on the uploaded video material through an operation page to generate a clipping result;
and the user saves the clipping result and shares the clipping result quickly, and the sharing address is shared and spread in a plurality of platforms including WeChat and QQ.
The invention has the beneficial effects that: the video file can be generated quickly based on the cloud, and can be conveniently and quickly shared in transmission.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a cloud-based video editing method includes the following steps:
the user side uploads the materials to the background server side through the system page (for example, a general user can upload the teaching parameter materials);
a user carries out operations such as clipping, arranging and the like on the uploaded video material through an operation page to generate a clipping result;
the operation page is concise and clear, certain habits of people in use are considered as much as possible, the operation is simple, and the background responds to the user every time the operation is performed;
and the user saves the clipping result and shares the clipping result quickly.
The sharing of video resources can be realized through sharing, especially some teaching videos are convenient for students to watch, and therefore teaching efficiency is improved.
The background server is provided with a server video platform and is used for receiving video materials uploaded from the user side through a page;
the system page of the background server is a provided video uploading interface;
on a video uploading interface, slicing the uploaded video: repackaging the video uploaded by the user according to the video format requirement, slicing the mpeg-ts small video every 6 seconds, recording an index file of the video slices, and performing warehousing processing on the video;
and the storage processing is to record the video information data to a database of the background server and store the video information data, and each video segment contains corresponding video information, such as information related to shooting time, shooting place and the like.
A video clip operation page provided by a user operation interface of the background server;
as shown in fig. 2, the video clip operation page is a page where a user performs operations such as clipping, dragging, adding background music, adding a watermark, and the like on the uploaded video material by operating a button of the page;
wherein, the video index (m3u8 file) is regenerated for the slice data by fast searching and finding the video slice data corresponding to the time interval by comparing the video index (m3u8 file) with the time interval of the beginning and the end of the video clip;
and the user clicks on the clip operation to save, and the clip result (m3u8 file) is saved.
As shown in fig. 3, after finishing the clipping, fast sharing is performed, and the sharing method includes:
the user can quickly share the editing result;
the user clicks a 'share' button of the clip page;
the background server quickly generates a sharing address;
the address can be shared to platforms such as WeChat, QQ and the like.
The method is used for editing based on the cloud, the video is repackaged according to mpeg2-ts (ISO/IEC _13818-1) format requirements when the video is uploaded, one mpeg-ts small video slice is generated every 6 seconds, and an index file (m3u8) of the video slice is recorded. During clipping, slices corresponding to the clip start time and the clip end time interval are quickly retrieved, and the clip slice set is regenerated into m3u8 indexes, so that millisecond-level clipping can be achieved, and clipping waiting time is greatly reduced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
