Embodiment 1

[0050] Such as figure 1 As shown, it is a method for scheduling a transcoding task described in Embodiment 1 of the present application, the method includes:

[0051] Step 101, obtain corresponding video attribute information from the video that needs to be transcoded, and generate a transcoding task with score label information in combination with preset score rules.

[0052] Specifically, the video attribute information includes: physical attributes and service attributes of the video, wherein the physical attributes specifically include basic information such as video duration, bit rate, and / or resolution; the service attributes specifically refer to the business category, such as: live streaming, advertising, news and / or film and television dramas, etc. In practical applications, the business category of the video is determined by the video uploader by checking the corresponding options before uploading the video. Of course, the method of determining the business category...

Embodiment 2

[0061] Such as figure 2 As shown, it is a method for scheduling a transcoding task described in Embodiment 2 of the present application. The method includes:

[0062] In step 201, the corresponding physical attributes and business attributes are acquired from the video that needs to be transcoded, and a transcoding task with score label information is generated in combination with preset score rules. Wherein, the video that needs to be transcoded is an uploaded video (specifically, it may be a video uploaded to a corresponding transcoding server, which is not limited here).

[0063] In step 201, the physical attribute is specifically basic information such as video duration, bit rate and / or resolution; the business attribute is specifically the business category to which the video belongs, such as: live broadcast, advertisement, news and / or or film and television dramas, etc.

[0064] Wherein, the preset score rule is specifically: preset scores corresponding to different v...

Embodiment 3

[0081] For such as figure 2 The scheduling method for the transcoding task shown, wherein step 203:

[0082] For the transcoding tasks in each resource pool queue, transcoding processing is performed according to a first-in-first-out processing mechanism.

[0083] In the above step 203, it also includes: extracting the transcoding task with a special label in each resource pool, and preempting the transcoding task that is being transcoded according to the first-in-first-out processing mechanism, the preempted transcoding task The processing of the transcoding task is suspended, and at the same time, the transcoding task with a special label is prioritized for processing, and the preempted transcoding task is queued after the transcoding task with a special label according to the first-in-first-out processing mechanism. Perform transcoding.

[0084] Specifically, for the transcoding task with a special tag, in addition to generating an interrupt tag, it can also generate a c...

Abstract

The invention discloses a transcoding task scheduling method and system. The method comprises the steps of acquiring corresponding video attribute information from a video to be transcoded and generating transcoding tasks containing score label information based on a preset score rule, placing the transcoding tasks containing the score label information in corresponding resource pool queues according to a preset score grading rule, and conducting transcoding on the transcoding tasks in each resource pool queue based on the first-in first-out processing mechanism. According to the transcoding task scheduling method and system, judgment of the priority and code rate of the video to be transcoded is conducted according to a preset video attribute rule, grouping is conducted at the same time according to the performance of a transcoding machine, and therefore the problem that current transcoding machines of video websites can not conduct transcoding task scheduling reasonably according to the state of a server and transcoding task attributes is effectively solved.

Description

technical field [0001] The present application relates to the field of video transcoding, and more specifically, to a method and system for scheduling transcoding tasks. Background technique [0002] Video websites convert abundant video resources into formats suitable for network playback, so that people can access the corresponding video websites through computer terminals, mobile terminals or TV terminals with networking functions to watch various videos. [0003] Different video resources have different video formats, and not all video formats are suitable for network transmission and playback. Usually, video websites will convert different video resources into ".flv" and ".mp4" formats The video is then transmitted over the network, among which, the ".flv" format is suitable for transmission and playback on TV terminals, and the ".mp4" format is suitable for network transmission and playback on computers and mobile terminals. That is to say, the video website needs to ...
