Embodiment Construction

[0050] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0051] Such as figure 1 As shown, the distributed transcoding method includes the following steps:

[0052] S1. Generate an upload task according to the basic information of the target video file, and upload the target video file to the server;

[0053] S2. Verify the uploaded file according to the upload task, and if it passes, proceed to step S3, otherwise terminate the subsequent operation;

[0054] S3, increase the tr...

Abstract

The invention discloses a distributed transcoding method, which includes the following steps: S1, uploading to a server; S2, performing verification; S3, separating data streams; S4, fragmenting video stream data; S5, generating transcoding Task queue; S6, transfer the task information to the transcoding unit in the idle state for transcoding; S7, judge whether all tasks to be transcoded have been completed, if so, enter step S8, otherwise return to step S6; S8, transcode the The sub-videos are synthesized into a complete video stream and encapsulated with other separated stream data to generate a complete transcoded data file. The present invention can quickly complete data slicing based on data block slicing, and at the same time adds GOP detection to ensure imaging quality; by increasing the calculation amount of sub-tasks and broadening the task granularity, the system overhead caused by frequent tasks is reduced.

Description

technical field [0001] The invention relates to the field of video data processing, in particular to a distributed transcoding method. Background technique [0002] In today's mobile Internet environment, a large number of video data in different formats and specifications are being generated from different devices. Compared with the past, a large number of different video standards, different terminal equipment, and different transmission networks have been put into use. Video transcoding is a method of converting the encoding method or display method of the original video into another different format, so as to meet the needs of different scenarios. Generally speaking, the transcoding process is a calculation-intensive task. According to the video frame rate and resolution improvement, the time required for calculation will increase greatly. [0003] With the development of science and technology and the popularization of cloud computing services, the performance of comp...
