In order to solve the above-mentioned technical problem, the embodiment of the invention provides a kind of multi-medium data recording method and devices.
This method can be applied to the various electronic equipments such as mobile phone, computer, specifically without limitation.
A kind of multi-medium data method for recording provided in an embodiment of the present invention is described in detail first below.
Fig. 1 is a kind of flow diagram of multi-medium data method for recording provided in an embodiment of the present invention, comprising:
S101: multi-medium data is obtained.
Multi-medium data in the present embodiment may include video data, audio data etc., specifically without limitation.
In addition, the multi-medium data in the present embodiment can be stream medium data (data flow).Streaming Media (Streaming
Media it is the media broadcast when passing) using stream transmission, is broadcast when passing while refer to service provider's transmission media, user
It can receive and watch or listen to the media data transmitted.Stream medium data can be image capture device (for example, network
Video camera) data flow that acquires in real time, or other.Alternatively, the multi-medium data obtained in the present embodiment may be
The multi-medium data being stored in remote server, specifically without limitation.
The application scenarios of the embodiment of the present invention can be as shown in Fig. 2, the equipment for executing this programme (be hereinafter referred to as originally set
It is standby) with image capture device and storage server communication connection (centre can pass through switching equipment), this equipment can both obtain
The multi-medium data that image capture device acquires in real time is taken, the multi-medium data also stored in available storage server.
S102: the key frame in the multi-medium data is determined.
As an implementation, dissection process can be carried out to the multi-medium data obtained in S101, obtains data frame
Information, the data frame information include one or more of: frame length, frame type, frame address；Believed according to the data frame
Breath determines key frame in the multi-medium data.
In embodiments of the present invention, the S101 multi-medium data obtained can be divided into and supports data cached and does not support to delay
Deposit data, for example, the number that TS (Transport Stream) data or PS (Program Stream) data etc. can cache
According to, belong to support it is data cached；RTP (Real-time Transport Protocol, real-time transport protocol) data etc. are only
To transmit the data that cannot cache, belong to do not support it is data cached.
It will be understood by those skilled in the art that multi-medium data is split as unit of frame, is parsed, available number
According to frame information.If the multi-medium data is that support is data cached, the data frame letter that data cached is encapsulation of data, is obtained is supported
Breath generally comprises: frame type, frame time, naked frame address, naked frame length, frame length with encapsulation etc.；If the multi-medium data
It is data cached not support, do not support that data cached is unencapsulated uncorrected data, obtained data frame information generally comprises: frame class
Type, frame time, naked frame address, naked frame length etc., wherein not including the frame length with encapsulation.
Using these data frame informations, key frame can be determined.For example, can determine that the frame is according only to frame type
No is key frame, alternatively, can also address to key frame or length be marked, according to other numbers such as frame address, frame length
According to frame information, key frame can also be determined.
As an implementation, before S102, the configuration information of the multi-medium data can be first obtained, it is described to match
Include data encryption information and recording demand information in confidence breath；In this case, S102 may include: to be added using the data
The multi-medium data is decrypted in confidential information, the multi-medium data after being decrypted；Multimedia number after the decryption
According to middle determining key frame.
It is appreciated that needing to know the recording demand of user before recording to multi-medium data.It therefore, can be with
The configuration information of multi-medium data is obtained, includes to record demand information in the configuration information, for example, the duration or file recorded
Size etc., alternatively, user, which is also an option that, only records key frame, it is specific to record demand without limitation.
In an alternate embodiment of the present invention where, the multi-medium data obtained in S101 can be encryption data, above-mentioned
It can also include data encryption information in configuration information, for example, whether the multi-medium data obtained is encryption data, to multimedia
The key information etc. that data are decrypted belongs to the data encryption information.In this way, this equipment can use data encryption letter
The multi-medium data of encryption is decrypted in breath, then carries out dissection process to the multi-medium data after decryption again, determines to close
Key frame.
S103: the non-key frame after identified key frame and the key frame is cached.
In embodiments of the present invention, by key frame, multi-medium data is cached.For video data, delay
The data deposited can be one or more complete GOP.
As an implementation, it when being cached to multi-medium data, if present frame to be cached is key frame, deletes
Current is data cached, and caches to the key frame；If present frame to be cached is non-key frame, to described non-key
Frame is cached.
It is appreciated that data are cached frame by frame as unit of frame when being cached to multi-medium data.Still with video
For data, using this embodiment, only a GOP is cached, it is (to be cached when the I frame of next GOP arrives
Present frame is I frame), (namely current is data cached, has cached and not deleted for the multi-medium data that caches before deleting
Data), it caches each data frame of the GOP frame by frame by the I frame, until the I frame of next one GOP arrives, so recycles.
In this manner it is ensured that caching multi-medium data by key frame, there is no can not decoded non-key frame (namely lose
The non-key frame of key frame needed for decoding is lost).
If since playing multi-medium data, saving complete multi-medium data by the way of prerecording, in this way,
Occupy biggish memory source；And in above embodiment, the memory source of a GOP size is at most occupied, compared to use
The mode of prerecording, reduces memory consumption.
Above in content, by multi-medium data be divided into support it is data cached and do not support it is data cached, to both data
The mode cached can be different, as shown in Figure 3:
It is data cached for supporting, spatial cache is created, identified key frame and institute are saved in the spatial cache
State the non-key frame after key frame；
It is data cached for not supporting, chained list is created, identified key frame and the key are saved in the chained list
Non-key frame after frame.
In present embodiment, cache node can be distributed for linked list data, the corresponding cache node of every frame data should
Cache node can be understood as the memory headroom in this equipment.
It will be understood by those skilled in the art that due to supporting that data cached is encapsulation of data, it can directly will acquire
Encapsulation of data save to spatial cache, when subsequent recording, the encapsulation of data is directly obtained from spatial cache；It is slow without supporting
Deposit data comes for unencapsulated uncorrected data, and the uncorrected data for needing will acquire saves as linked list data, when subsequent recording, to chained list number
It is handled according to being packaged.
S104: after receiving record command, the multi-medium data of caching is recorded.
It is appreciated that when user needs to record multi-medium data record command can be sent, for example click and record
Button etc., specifically without limitation.After receiving the record command, the multi-medium data cached in S103 is recorded.
In an alternate embodiment of the present invention where, the multi-medium data cached in S103 is real-time update, such as on
It states in an embodiment, only caches a newest GOP data, after receiving record command, there is only newest in this equipment
GOP data, which is recorded.Alternatively, in other embodiments, there are newest in this equipment
Audio data or multiple GOP data, after receiving record command, record the latest data in this equipment.
While recording, S103 is still in execution, and the multi-medium data of caching is updating always, therefore, can be right always
The multi-medium data of S103 caching is recorded, until recording terminates.Alternatively, after receiving a period of time of record command,
Directly the multi-medium data of acquisition is recorded, until recording terminates, during this, S103 is still in execution, more matchmakers of caching
Volume data is updating always, and this is also rational.
In said one embodiment, comprising recording demand information in the configuration information of acquisition, in this case, S104 can
With are as follows: according to the recording demand information, the multi-medium data of caching is recorded.
For example, in the recording demand information comprising " recording when it is 10 minutes a length of ", then record 10 minutes multimedia numbers
According to according to being described above, this 10 minutes multi-medium data can be recorded all for the data of caching, can also part needle
The data of caching are recorded, are partially directly recorded for the data obtained.
Alternatively, including " only recording key frame " in the recording demand information, then recorded only for key frame, this is all
Reasonably.Recording demand can there are many, specifically without limitation.
According to content above, multi-medium data is divided into support it is data cached and do not support it is data cached, and be directed to this two
Kind data carry out the caching of different modes, in this case, the recording of different modes can also be carried out for both data:
It is data cached for supporting, the multi-medium data in the spatial cache is stored as recorded content；
It is data cached for not supporting, the multi-medium data in the chained list is packaged, recorded content is generated.
It will be understood by those skilled in the art that as shown in figure 3, due to supporting that data cached is encapsulation of data, it can be with
The encapsulation of data that directly will acquire is saved to spatial cache, and when subsequent recording, the encapsulation of data is directly obtained from spatial cache；
Without support it is data cached come for unencapsulated uncorrected data, the uncorrected data for needing will acquire saves as linked list data, subsequent recording
When, processing is packaged to linked list data.
It being described according to content above, the multi-medium data that S101 is obtained can be encryption data, as an implementation,
The content that S104 is recorded can also be encrypted.In present embodiment, acquired multimedia number can be first judged before S103
According to whether being encryption data and whether encrypted to recorded content:
If being encrypted to recorded content and acquired multi-medium data being not encryption data, alternatively, not in recording
Appearance is encrypted and acquired multi-medium data is encryption data, then:
S103 includes: creation chained list, saved in the chained list determined by it is non-after key frame and the key frame
Key frame；
S104 includes: to be packaged the multi-medium data in the chained list, generates recorded content.
It can be with specifically, above comprising recording demand information in the configuration information mentioned of content, in the recording demand information
Comprising whether encrypting recorded content, therefore, can judge whether to carry out recorded content according to the recording demand information
Encryption.In addition, above it is mentioned that also including data encryption information in the configuration information, this equipment can use the number in content
According to encryption information, whether the multi-medium data for judging that S101 is obtained is encryption data, and in the case where it is encryption data,
Using the data encryption information, it is decrypted.
It will be understood by those skilled in the art that if the multi-medium data that S101 is obtained is non-encrypted data, and S104 is recorded
Content processed is encryption data, even if the data that S101 is obtained are that support is data cached, can not directly be saved it empty to caching
Between, but it is decapsulated, the data after decapsulation are stored as linked list data, so that when subsequent recording, it can be right
Linked list data is packaged processing, and during being packaged, it is encrypted, and generates encrypted content (such as encryption view
Frequently).
Correspondingly, if the multi-medium data that S101 is obtained is encryption data, and S104 recorded content is non-encrypted data,
Even if the data that S101 is obtained are that support is data cached, it is also desirable to decapsulation be decrypted to it, the number after decapsulation will be decrypted
According to being stored as linked list data, when subsequent recording, processing is packaged to linked list data, and be no longer encrypted, generated
Unencrypted content (such as unencryption video).
And if the multi-medium data that S101 is obtained is non-encrypted data, S104 recorded content is non-encrypted data, then will
Multi-medium data, which is divided into, to be supported data cached and does not support data cached, and corresponding cache way, recording side are utilized respectively
Formula is handled.
Correspondingly, S104 recorded content is encryption data if the multi-medium data that S101 is obtained is encryption data, it will be more
Media data, which is divided into, to be supported data cached and does not support data cached, and corresponding cache way, recording mode are utilized respectively
It is handled.
Using this embodiment, user can record encrypted content or unencrypted content according to actual needs, experience compared with
It is good.
Using embodiment illustrated in fig. 1 of the present invention, the key frame in multi-medium data is determined, more matchmakers are cached by key frame
Volume data records the multi-medium data of caching after receiving record command, that is to say, that in the present solution, record
Multi-medium data be by key frame, key frame required for non-key frame decodes will not be lost, therefore there is no nothings
The decoded non-key frame of method, on the one hand reduces resource waste；On the other hand, subsequent when being played out to recorded content, it is existing
Usually exist in scheme can not decoded non-key frame, after user's click play, what is played first is that these can not be decoded non-
Key frame, user needs just see normal pictures, waiting for a long time, poor user experience until next key frame, and applies
This programme, there is no can not decoded non-key frame, directly broadcasting normal pictures, reduce period of reservation of number.
In addition, if electronic equipment starts after the record command for receiving user's transmission to the multimedia number received
According to being recorded, since electronic equipment is there are the reaction time, cause since receiving the record command, the record multimedia number to
It is not recorded according to the multi-medium data of this period；And the embodiment of the present invention is applied, before receiving record command, just
The buffer multimedia data by key frame is recorded the multi-medium data of caching, also after receiving record command
To say, since receive the record command, the multi-medium data of recording multi-media data this period has been buffered to, because
This, the multi-medium data of this period can also be recorded, and improve recording result.
Further more, if electronic equipment after the record command for receiving user's transmission, before reacquiring the record command
The multi-medium data of preset time period then repeats to obtain data, wastes Internet resources；And the embodiment of the present invention is applied, it is receiving
To before record command, the buffer multimedia data by key frame, after receiving record command, to the multimedia number of caching
According to being recorded, that is to say, that the embodiment of the present invention caches multi-medium data, rather than repeats to obtain, and reduces net
The waste of network resource.
A kind of specific embodiment is provided below:
As shown in figure 4, may include in this equipment: playing control module 401, data resolution module 402, data processing mould
Block 403, data storage module 404.
Playing control module 401 obtains multi-medium data from image capture device or storage server, and obtaining should
Multi-medium data corresponding configuration information comprising data encryption information and records demand information in the configuration information.
Playing control module 401 is by current pending data in acquired multi-medium data and the multi-medium data
The information such as initial address, the length of (present frame) are sent to data resolution module 402.
As shown in figure 5, AD segment data is the multi-medium data that playing control module 401 is sent to data resolution module 402,
