Embodiment 1

[0032] Such as Figure 1 to Figure 7 As shown, a deduplication method to prevent repeated video transcoding includes the following steps:

[0033] Step S1: Obtain the video transcoding task ID, and obtain the address of the video file to be transcoded according to the video transcoding task ID, thereby obtaining the video file to be transcoded.

[0034] In this step, the video transcoding task ID represents the address of the video file to be transcoded on the server and the transcoding status. The transcoding status includes whether the video file has been transcoded or not.

[0035] Step S2: According to the obtained video file, generate the unique corresponding inspection value of the video file. The inspection value indicates that the video file can be uniquely determined. The inspection value is preferably an MD5 value or a HASH value or a CRC32 value. For example, the video can be uniquely determined by the MD5 value files, different video files have different MD5 value...

Embodiment 2

[0057] Such as Figure 8 As shown, the present invention also relates to the processing terminal 100 implementing the method steps of Embodiment 1, which includes:

[0058] Memory 101, for storing program instructions;

[0059] The processor 102 is configured to run the program instructions to execute the steps in the deduplication method for preventing repeated video transcoding in the first embodiment.

Abstract

The invention relates to a deduplication method for preventing repeated transcoding of a video and a processing terminal, and the method comprises the following steps: S1, obtaining a video transcoding task ID, and obtaining a to-be-transcoded video file according to the video transcoding task ID; S2, generating a check value of the video file according to the obtained video file; S3, respectivelycomparing the check value of the generated video file with the check value of each video in the video data table, if a consistent check value exists in the video data table, marking the video file and not transcoding, and if the consistent check value does not exist in the video data table, transcoding the video file to obtain a transcoded video. According to the invention, repeated transcoding of the same video can be prevented, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of video transcoding, in particular to a deduplication method and a processing terminal for preventing repeated video transcoding. Background technique [0002] Most of the current video transcoding is task-independent. When dealing with a large number of repeated videos, each video request needs to be transcoded once, which requires multiple transcodings, which takes up a lot of space and transcoding time. For example, user A of a certain video website uploads video A, transcodes video A to obtain videos A1, A2, and A3; user B uploads video B, although video B may be the same as one of videos A, A1, A2, and A3 Or multiple same, the existing video transcoding method still transcodes video B to obtain the corresponding transcoded video, instead of using video A, A1, A2, A3 as the transcoded video of video B. When a user sends a video request to watch video B to the video website, the system calls the transco...
