Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] An adaptive video inpainting method such as figure 2 and image 3 shown, including the following steps:

[0028] Step 1, build a video format library (VFL), the video format library includes the encapsulation format of multiple video files, wherein the video format library can also realize "hot swapping" of the video container, and also can realize the dynamic loading of the video container;

[0029] Step 2. Carry out sample video interception of the video to be repaired. The length of the interception can be dynamically adjusted according to the repair environment at that time, as long as it does not exceed the video size, and the intercepted video segment is used as a sample video;

[0030] Step 3. Load the video format library into the linked list, iterate the linked list, and obtain the package format corresponding to the sample...

Abstract

The invention discloses a self-adaptive video restoration method, which comprises the following steps of: constructing a video format library which comprises a plurality of packaging formats of video files; performing sample video interception on the to-be-restored video, and taking the intercepted video segment as a sample video; loading the video format library into a linked list, and iterating the linked list to obtain a packaging format corresponding to the sample video; analyzing and repairing the sample video according to the packaging format, and storing the current repaired video into a cache space after repairing is completed; carrying out playability detection on the video in the cache space; if the evaluation result is that the to-be-repaired video can be normally played, analyzing and repairing the to-be-repaired video according to a packaging format corresponding to the sample video to obtain a repaired complete video; and otherwise, splitting the intercepted video segment into two segments, taking the video of which the length is greater than the minimum value after splitting as a sample video, and continuing to analyze and repair. The problem that a damaged video with an unknown packaging format cannot be repaired in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of restoration methods, and relates to an adaptive video restoration method. Background technique [0002] Videos in various formats are ubiquitous in our lives. According to YouTube, people around the world watch 1 billion hours of video a day. It can be seen how big the market for video restoration is. In addition, there are various videos, such as surveillance, recorder, TF card, video in mobile phone memory card, video in computer, etc. [0003] Also, videos of certain specific scenes are extremely valuable. For example, for videos associated with a case, they often determine the direction of the case and have great research value. Therefore, it is very necessary to repair the broken video associated with the case. [0004] At present, a video file is usually generated by encapsulating video data in a video container using a video encapsulation technology, and the video container refers to a file fo...
