Grader and transcoder can use different server hardwares to realize.
This utility model, by being classified by original multimedia file, determines transcoding strategy by class, thus can optimize transcoding server, by Optimized Operation strategy, on the premise of not increasing transcoding server hardware spending, it is achieved that fast transcoding.This utility model can cause video to call situation complicated when responding rapidly to multiple, the changeable video playback demand of user, in the case of video genre abundance, still can guarantee that video playback is smooth, improves Consumer's Experience.If no special instructions, multimedia file described in the utility model is generally video and/or audio file.
Embodiment two
As in figure 2 it is shown, multi-media transcoding scheduler includes disclosed in present embodiment: grader, the transcoder coupled with grader.
Combiner that the transcoding server that the scheduler that described transcoder also includes the food slicer coupled with grader, couple with grader and food slicer respectively couples with scheduler couples with transcoding server, couple multimedia storage server with transcoding server and combiner respectively；It is additionally provided with preprocessor between described grader and food slicer；
Grader carries out classification process according to original multimedia file and destination multimedia file attribute to original multimedia file；Described food slicer for being cut at least two fragment by original multimedia file；The multimedia file of transcoding treated for the service behaviour of multiple stage transcoding server by described scheduler for distributing；Described preprocessor for being converted into default reference format by original multimedia file；Described transcoding server is for carrying out transcoding to multimedia file；Described combiner forms destination multimedia file for the fragment after transcoding being merged；Described multimedia storage server is used for storing destination multimedia file.
Present embodiment is complicated in view of system source video sequence to be processed, form and the situation of video are various, likely system is processed video content and bring burden, even some special format may cause follow-up processing module to process, therefore, for such video content, video format conversion is carried out by preprocessor, it is converted into suitable reference format, through such conversion, the most even can directly reduce video capacity, reduction system processing load, even if capacity changes little, also the problem that video content possibly cannot be identified can be solved at System Back-end.Scheduler can carry out parallel processing to the fragment of section respectively according to meeting the different transcoding server of situation flexible arrangement, can utilize hardware resource to greatest extent, improve again transcoding efficiency.
Embodiment three
Present embodiment is illustrated as a example by original multimedia file is as video file.
Multi-media transcoding scheduler disclosed in present embodiment includes following 7 kinds of structures:
Grader.Grader is responsible for classifying video-processing mode according to original multimedia file attribute, target video file attribute.Generally, there are 3 kinds: directly transcoding；Transcoding is sent after burst；After pretreatment, burst send transcoding again.
Preprocessor.The video file that preprocessor is responsible for needing section carries out pretreatment.Pretreated file can turn section.Purpose: in view of system source video sequence to be processed is complicated, form and the situation of video are various, likely system is processed video content and bring burden, even some special format may cause follow-up processing module to process, therefore, for such video content, video format conversion is carried out by preprocessor, it is converted into suitable reference format, through such conversion, the most even can directly reduce video capacity, reduction system processing load, even if capacity changes little, also the problem that video content possibly cannot be identified can be solved at System Back-end.
Food slicer.Food slicer is responsible for according to rule, video file is divided into multiple fragment.
If code check is uniform, video can be divided equally cutting
If code check is uneven, as video content be motion or static time code check different, when cutting, approximately the same carry out cutting for principle according to the time of transcoding consumption.
Scheduler.Scheduler is responsible for the service behaviour of multiple stage transcoding server and distributes the video file treating transcoding.
Transcoding server.There is multiple stage transcoding server.Transcoding server completes video file format conversion, including decoding and 2 processes of coding.
The service behaviour of multiple stage transcoding server can be variant, then the load balance of multiple stage transcoding server is by if desired for section, then food slicer and scheduler complete jointly, as need not section, is then mainly completed by scheduler
Combiner.Belong to a video file multiple bursts after transcoding, combiner be assembled into one section of complete video.
Video storage server.Video storage server is responsible for storing the video file of various form.
The code-transferring method job step of present embodiment Optimized Operation strategy is as follows:
The first step, according to original multimedia file attribute, target video file attribute, grader determines transcoding mode.
Generally, there are 3 kinds of transcoding strategy: a, as less in multiple video file contents, directly send scheduler.B, as many in multiple video file contents, send food slicer to send scheduler after cutting into slices.C, as video format is lack of standardization, is not suitable for direct slicing, then enter after original multimedia file is carried out pretreatment by preprocessor and send food slicer and scheduler.
Please supplement, the classifying rules of grader.
Second step, food slicer and scheduler are cut into slices according to the work efficiency of each transcoding server, then process the video distribution after section to corresponding transcoding server；
3rd step, after transcoding server transcoding, has multiple files of section mark to export to VRAM after being combined as a complete file in combiner；The file of mark of not cutting into slices is directly output to video server.
This utility model, when responding rapidly to multiple, the changeable video playback demand of user, causes video to call situation complicated, in the case of video genre abundance, still can guarantee that video playback is smooth, improves Consumer's Experience.
It should be noted that, in view of system source video sequence to be processed is complicated, form and the situation of video are various, likely system is processed video content and bring burden, even some special format may cause follow-up processing module to process, therefore, for such video content, video format conversion is carried out by preprocessor, it is converted into suitable reference format, through such conversion, the most even can directly reduce video capacity, reduction system processing load, even if capacity changes little, also the problem that video content possibly cannot be identified can be solved at System Back-end.This utility model, by being classified by original multimedia file, determines transcoding strategy by class, and by the load balance of multiple stage transcoding server, thus can optimize transcoding server, by Optimized Operation strategy, on the premise of not increasing transcoding server hardware spending, it is achieved that fast transcoding.This utility model can cause video to call situation complicated when responding rapidly to multiple, the changeable video playback demand of user, in the case of video genre abundance, still can guarantee that video playback is smooth, improves Consumer's Experience.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
