Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the present invention.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present invention are consistent.
Embodiments provide a kind of data processing method, as shown in Figure 1, the method comprising the steps of S101-S102:
In step S101, obtain video data;
In step s 102, decapsulation operation is carried out to video data, to obtain the fragment total number information of multimedia file fragment corresponding to video data and multimedia file;
In step s 103, control multiple audio frequency and video treating apparatus and the fragment total number information of multimedia file is forwarded to task management device, task corresponding to multimedia file is created according to fragment total number information with control task management devices, and generate fragment bitmap according to fragment total number information, wherein, figure place in fragment bitmap is consistent with fragment sum, the fragment of every correspondence in fragment bitmap;
In step S104, multimedia file fragment is distributed to multiple audio frequency and video treating apparatus and processes, and control each audio frequency and video treating apparatus be sent to task management device after processing into corresponding multimedia file fragment;
In step S105, control task management devices receives the multimedia file fragment after process, and utilizes the treatment state of each multimedia file fragment of fragment bitmap record;
In step s 106, according to the treatment state of multimedia file fragment in fragment bitmap, determine whether that the multimedia file fragment after to process carries out encapsulation operation, to obtain the video data after processing.
In this embodiment, multiple audio frequency and video treating apparatus is used to carry out parallel processing to video file, and pass through the treatment state of each multimedia file fragment after fragment bitmap recording processing, determine whether to carry out encapsulation operation according to the treatment state of multimedia file fragment in fragment bitmap, obtain the video data after processing, thus ensure that the integrality of the video data after process, greatly reduce the time needed for process, reduce the processing pressure of system simultaneously, decrease the possibility of system crash.
In one embodiment, the title of multimedia file fragment comprises multimedia file title, fragment title and/or multimedia file type.Wherein, multimedia file comprises video file and audio file.Then multimedia file fragment title can be expressed as AT-XX-XXX.goa or VT-XX-XXX.gov, and wherein, AT represents audio frequency, and VT represents video, and XX represents file name, and XXX represents fragment title.Multimedia file fragment total number information then can be expressed as AT-XX.total file and VT-XX.total file.
In one embodiment, every in fragment bitmap comprises the first state and the second state, and the first state is for representing the multimedia fragment after receiving the corresponding process that puts in place, and the second state is for representing the multimedia fragment after not receiving the corresponding process that puts in place.
In this embodiment, can in fragment bitmap, the accepting state of identification of multimedia fragment is carried out with different numerical value, as when not receiving the multimedia fragment in fragment bitmap after this corresponding process, this position represents with 0, when receiving the multimedia fragment in fragment bitmap after this corresponding process, this position represents with 1.Below with a specific embodiment, describe technical scheme of the present invention in detail.
In the present invention, because audio frequency and video treating apparatus does not process multimedia file fragment total number information, after receiving, task management device can be sent at once.So task management device first can receive multimedia file fragment total number information, and according to file name creation task, the multimedia file fragment after the process that stand by tone video process apparatus sends, i.e. A-XX-XXX.goa file and V-XX-XXX.gop file.Task management device generates bitmap according to the fragment sum in media file fragment total number information, and the figure place in bitmap is consistent with fragment sum, and the initial value of every is 0.Often receive an A-XX-XXX.goa or V-XX-XXX.gop file, the relevant position in bitmap is revised as 1.
As shown in Figure 2, in one embodiment, above-mentioned steps S106 comprises step S201:
In step s 201, when all positions in fragment bitmap are all in the first state, determine that the multimedia file fragment after to process carries out encapsulation operation.
In the above-described embodiments, when all positions of bitmap are 1, namely represent that reception is complete.Receive complete after, namely Voice & Video all receives complete, then start to encapsulate.During encapsulation, read the data of each fragment according to the order of sequence, encapsulate.
Wherein, can encapsulate when fragment receives complete, certainly, also can encapsulate on reception limit, limit.
As shown in Figure 3, in one embodiment, above-mentioned steps S106 can also comprise step S301-S302:
In step S301, judge that task management device is current and whether be in idle condition;
In step s 302, task management device is current be in idle condition time, when the figure place being in the first state in fragment bitmap exceedes default figure place, determine that the multimedia file fragment after to process carries out encapsulation operation.
In this embodiment, if task management dress is in idle condition, even if the fragment of certain file does not arrive entirely, but the figure place being in the first state in fragment bitmap exceedes default figure place, when such as receiving half or more than half fragment, also can start to encapsulate.Like this, both ensure that processing speed, too much can not take again the resource of task management device.
Certainly, multithreading can also be opened on task management device, thread process task, a namely file.The fragment of which file arrives, and just continues which task of process.Under the restriction of disk I/O, number of threads has the upper limit, is as above limited to 5.
Following is apparatus of the present invention embodiment, may be used for performing the inventive method embodiment.
