The embodiments of the invention provide a kind of compression method and device of video memory space, video can be avoided to be compressed Rear video plays slack situation.The embodiment of the present invention can be applied in the equipment for needing to compress video memory space, example Such as it is applied to terminal or cloud storage space, wherein terminal can include the equipment such as computer, mobile terminal.
Below by specific embodiment, the present invention is described in detail.
Fig. 1 be video memory space provided in an embodiment of the present invention compression method a kind of schematic flow sheet, the side Method comprises the following steps:
Step S101:Original video files to be compressed are determined from the video file stored.
Specifically, determine that original video files to be compressed can include numerous embodiments, can according to preset rules, Original video files to be compressed are determined from the video file stored.Wherein, preset rules can be regarded what is stored Accessed duration reaches the video file of predetermined threshold value as original video files to be compressed or incited somebody to action in frequency file Access times are less than the video file of preset times threshold value as original to be compressed in preset duration in the video file stored Beginning video file, etc..
It is understood that after original video files to be compressed are determined from the video file stored, Ke Yifu A original video files of system are into caching or other memory spaces, to carry out subsequent treatment to it.
It is pointed out that the present embodiment is not limited the concrete form for storing the equipment of video file, i.e., video is literary Part can be stored in the local hard drive or other internal storage spaces of terminal, can also be stored in the resource pool in cloud storage space In.
Step S102:Obtain the resolution ratio of original video files.
In actual applications, graphics video processing software Adobe After Effects (AE) or video can be used to close The resolution ratio of video file is obtained into software Fusion or MPC software etc..
Step S103:According to preset rules, the resolution ratio of original video files is reduced, generates the video file after compression.
Wherein, the resolution ratio of video file is reduced according to preset rules, can be reduced according to default resolution gradient The resolution ratio of video file or the resolution ratio of original video files is reduced to default resolution value etc..Arrange below Lift a kind of specific embodiment.
In the present embodiment, step S103 can include:According to default former resolution ratio with compression after resolution ratio it is corresponding Relation, by the resolution ratio of each original video files be reduced to corresponding to compress after resolution ratio.
For example, the corresponding relation of default former resolution ratio and resolution ratio after compression see the table below.For example, original video is worked as When the resolution ratio of file is more than 1920 pixel 1080 pixels of *, the resolution ratio of the original video files is reduced to 1920 pixel * 1080 pixels.
Former resolution ratio/pixel Resolution ratio/pixel after compression
> 1920*1080 1920*1080
1920*1080~1280*720 1280*720
1280*720~768*432 768*432
768*432~512*288 512*288
It should be noted that the resolution ratio of video file is reduced into given resolution, can also use in the prior art Video processing software or Video Composition software realize, this belongs to prior art, and detailed process repeats no more.
Step S104:Video file after storage compression, deletes original video files.
It is understood that after original video files to be compressed are compressed into processing, also storage in equipment is regarded Original video files in the memory space of frequency file replace with the video file after compression, and it is empty could so to reduce video storage Between.
As shown in the above, the embodiment of the present invention is according to the resolution ratio of original video files to be compressed, according to default Rule, the resolution ratio of original video files is reduced, the video file after generation compression, then stores the video file after compression, And delete original video files.It is empty to reach compression video storage in the embodiment of the present invention by the way of video resolution is reduced Between purpose, it is different to compress the method for video memory space to video to be compressed take out frame processing in the prior art, All exist in the video file of each frame upon compression in inventive embodiments in original video files, therefore video can be avoided Slack situation is played by compression rear video.
In the embodiment shown in fig. 1, before step S103, i.e., according to preset rules, the original video text is reduced The resolution ratio of part, before generating the video file after compression, methods described can also comprise the following steps:
Judge the original video text for being not more than default minimum resolution threshold value in original video files with the presence or absence of resolution ratio Part, if it is present the original video files for being not more than default minimum resolution threshold value to resolution ratio carry out taking out frame processing.
Wherein, it can be 512*288 or other resolution values to preset minimum resolution threshold value.
It is understood that when the resolution ratio of original video files is too small, if carried out again to its resolution ratio at reduction Reason, the definition of the original video files after compression is too low, possibly can not meet the viewing needs of user.Therefore, regarded when original When the resolution ratio of frequency file is too small, it can be carried out to take out frame processing.
Specifically, carrying out taking out frame processing to original video files, numerous embodiments can be included, for example, can extract All I frames of original video files, according to default code check, by the video file after all I frames generation compression of extraction.
Can also be that according to preset ratio, the I frames of preset ratio are extracted from original video files, according to default code check, By the video file after the I frames generation compression of extraction.
In the embodiment shown in fig. 1, step S101, i.e., original video to be compressed is determined from the video file stored File can be carried out according to schematic flow sheet shown in Fig. 2, be specifically included:
Step S101A:Obtain the first numerical value of the storage size shared by the video file stored.
Illustrated below by taking terminal as an example.It is assumed that video file is stored in the E disks of local disk, then can be obtained Take the size of the memory space shared by the video file stored in E disks, it is assumed that be 80GB, i.e. the first numerical value is 80GB.
Step S101B:Judge whether the first numerical value meets preparatory condition, if it is, performing step S101C, otherwise, no Process.
Specifically, judging whether the first numerical value meets preparatory condition, a variety of embodiments can be included.It is exemplified below Several specific embodiments:
One kind is to judge whether the first numerical value is more than default memory space threshold value.
Assuming that default memory space threshold value is 85GB, if the first numerical value is more than 85GB, it is determined that the first numerical value meets pre- If condition, that is, illustrate that the memory space needs are compressed by.
Another kind is, obtains the default total value for being used to store the storage size of video file, then judges the Whether the ratio that one numerical value accounts for total value is more than preset ratio threshold value.
For example, the total value for the storage size that the local disk E disks obtained are used to store video file is 100GB, E The video file that disk has stored is 80GB, then judge whether 80/100=80% is more than preset ratio threshold value, if it is greater, then Illustrate that the video file of E disk storages is excessive, it is necessary to compress the video file of the E disks.
Step S101C:All or part of video file stored is defined as original video files to be compressed.
As a kind of specific embodiment, all or part of video file stored is defined as to be compressed original Video file, it can include:
Step 1:The last access time of each video file stored is obtained, according to current time, it is determined that often The current of the individual video file stored is not accessed duration.
Step 2:It is more than preset duration threshold value with the presence or absence of current not accessed duration in the video file for judging to have stored Video file, if it is present perform step 3, if it does not exist, then perform step 4.
Wherein, preset duration threshold value can be 3 days or 2 days.
Step 3:The video file that currently not accessed duration is more than preset duration threshold value is defined as to be compressed original Video file.
In actual applications, if the current of all video files in the video file stored is not accessed duration all More than preset duration threshold value, then the video file all stored is defined as into original video files to be compressed.If The current not accessed duration of partial video file in the video file of storage is more than preset duration threshold value, then by this part The video file stored is defined as original video files to be compressed.
If the video text that current not accessed duration is more than preset duration threshold value is not present in the video file stored Part, then in order to compress video memory space, original video files to be compressed are determined using the process of step 4~step 6.
Step 4:The video file stored is sorted according to the currently not accessed order of duration from big to small.
Step 5:Determine that current accessed duration is larger from the video file stored after sequence and take Storage size reaches the target video file of target value.
Wherein, target value is according to video file and default vacating space threshold value or default vacating space ratio-dependent 's.
Specifically, determine that target video file can include a variety of embodiments, for example, with default first numerical value For unit, the storage of larger, the original occupancy of current not accessed duration is determined from the video file stored after sequence Space is the first video file of the first numerical value, estimates the size after the first video file is compressed, and first after being compressed The size of video file vacating space, then compare the size of the vacating space and the magnitude relationship of default vacating space threshold value.
If the former is less than the latter, when determining current not accessed from the video file stored after sequence again The memory space of long larger, original occupancy is the first video file of 2 times of first numerical value, continues executing with and estimates the first video text Part compressed after size the step of.
If the former is more than the latter, and the difference of the size of vacating space and default vacating space threshold value is less than preset difference value Threshold value, then the first video file is defined as target video file.
Said process is illustrated with instantiation below.Assuming that default vacating space threshold value is 10MB, default first numerical value For 10MB, preset difference value threshold value is 5MB.Each video file stored is according to the currently not accessed row of duration from long to short Sequence is:
Video file 1 (4MB), video file 2 (6MB), video file 3 (10MB), video file 4 (2MB), video file 5 (5MB), video file 6 (10MB), video file 7 (10MB) ...
Wherein, the storage size taken in bracket for video file.Determine to work as in order from above-mentioned video file The first video file that the memory space of longer, the original occupancy of preceding not accessed duration is 10MB.Due to video file 1 and 2 Occupancy storage size and be 4MB+6MB=10MB, therefore by video file 1 and 2 collectively as the first video file.
Then, estimate to obtain taken after video file 1 and 2 is compressed storage size and be 6MB, then can Using the vacating space of the video file 1 and 2 after being compressed as:The sum for the storage size that video file 1 and 2 takes The storage size that 10MB- video files 1 and 2 take after being compressed and 6MB=vacating spaces 4MB.
Because vacating space 4MB is less than default vacating space threshold value 10MB, therefore weighed in order from above-mentioned video file It is new to determine first video file of the current memory space for not being accessed larger, the original occupancy of duration for 2 times of first numerical value.By In the storage size of the occupancy of video file 1,2 and 3 and it is 4MB+6MB+10MB=2 times of the first numerical value 20MB, therefore will Video file 1,2 and 3 is collectively as the first video file.
Then, estimate taken after video file 1,2 and 3 is compressed storage size and be 9MB, must can compress The vacating space of video file 1,2 and 3 afterwards is:The storage size and 20MB- videos that video file 1,2 and 3 takes The storage size and 9MB=vacating space 11MB, vacating space 11MB that file 1,2 and 3 takes after being compressed is big In default vacating space threshold value 10MB, and its difference 11MB-10MB=1MB is 5MB less than preset difference value threshold value, therefore can be with Video file 1,2 and 3 is defined as target video file.
Step 6:Target video file is defined as to original video files to be compressed.
From the above, in the present embodiment, current according to the video file stored is not accessed duration, will The video file that current not accessed duration is more than preset duration threshold value in the video file stored is defined as original to be compressed Beginning video file, i.e., the video file preferentially infrequently accessed user are defined as original video files, can avoid user The video file often accessed is compressed, therefore can improve Consumer's Experience.
In order to improve the compression efficiency to the memory space of equipment, embodiment illustrated in fig. 1 can also comprise the following steps, this A little steps are as shown in Figure 3.
Step S301:Detect in the video file stored with the presence or absence of the first video for having been subjected to reduction resolution processes File, if it is present performing step S302, otherwise, do not process.
Step S302:The last access time of each first video file is obtained, according to current time, it is determined that each The current of first video file is not accessed duration.
Step S303:The first video file that currently not accessed duration is more than preset duration threshold value is defined as to be compressed Video file.
Step S304:Obtain the resolution ratio of video file to be compressed.
Step S305:According to preset rules, the resolution ratio of video file to be compressed is reduced, generates the video text after compression Part.
Step S306:Video file after storage compression, deletes the video file to be compressed.
It should be noted that step S304~S306 and step S102~S104 are essentially identical, particular content can phase Mutual reference.
As shown in the above, in the present embodiment, differentiated if existing in the video file stored and having been subjected to reduction First video file of rate processing, and current not accessed duration in the first video file be present and be more than preset duration threshold value Video file, illustrate that user is not high to the attention rate of this partial video file.At this moment this partial video file can be defined as Video file to be compressed, and pair video file to be compressed determined is compressed processing, so as to improve the compression to memory space Efficiency.
Fig. 4 is another schematic flow sheet of the compression method of video memory space provided in an embodiment of the present invention, wherein, Video file is stored in the resource pool in cloud storage space.Methods described comprises the following steps:
Step S401:Determine resource pool to be detected.
In actual applications, multiple storage devices can be included in cloud storage space, are provided with each storage device more Individual resource pool, each resource pool are assigned the mark that uniquely can determine that the resource pool.It can be true to determine resource pool to be detected The numbering or address information of fixed resource pool to be detected.Also, safeguard there is resource pool information in cloud storage space, the resource pool information The total value of the storage size of mark, resource pool including each resource pool, the residual memory space size of resource pool, money The memory space threshold value in source pond, not accessed duration threshold value etc..
Wherein, the total value of the storage size of resource pool, the memory space threshold value of resource pool and not accessed duration The information that threshold value inputs when can be according to user establishing resource pond determines.
In the present embodiment, resource pool to be detected is determined, numerous embodiments can be included:
One kind is, according to predetermined period, to determine that the resource pool of predetermined number is made from all resource pools in cloud storage space For resource pool to be detected.Wherein, predetermined period can be 2 hours, or one day.Predetermined number can be 1, or 2.Predetermined period and the specific value of predetermined number can be according to setting be actually needed, and the present embodiment is not specifically limited to this.
Another kind is, according to preset rules, the resource pool of determination predetermined number from all resource pools in cloud storage space As resource pool to be detected.Wherein, preset rules can be chosen or randomly select successively according to set order, The present embodiment is not specifically limited to this.
Step S402:Obtain the of the storage size shared by the video file that each resource pool to be detected has stored Two numerical value.
Specifically, after resource pool to be detected is determined, each resource pool to be detected can have been obtained from resource pool information Storage size shared by the video file of storage.
Step S403:Judge whether each second value meets preparatory condition respectively.
Specifically, judging whether each second value meets preparatory condition respectively, numerous embodiments can be included:
One kind is to judge whether each second value is more than default memory space threshold value respectively.
Another kind is the total value for the storage size for obtaining each resource pool to be detected, judges each first respectively Whether the ratio that numerical value accounts for total value is more than preset ratio threshold value.
For example, the total value of resource pool A storage size is 100GB, preset ratio threshold value is 80%, then, work as A In the second value of video file that has stored when being more than 80GB, it may be determined that the second value meets preparatory condition.
, can be with it is understood that when the storage size of all resource pools in cloud storage space is all basically identical By the way of judging whether each second value is more than default memory space threshold value.When all resource pools in cloud storage space Storage size it is uneven or difference it is more when, using judge each first numerical value account for total value ratio whether be more than in advance If the mode of proportion threshold value is more reasonable.
It should be noted that according to user when default memory space threshold value and preset ratio threshold value can be resource pool establishments Setting determine or equipment setting themselves.
Step S404:The video file that all or part met in the resource pool of preparatory condition has stored is defined as treating The original video files of compression.
Specifically, determine that original video files to be compressed can include various ways, can be according to preset rules, from completely Original video files to be compressed are determined in the resource pool of sufficient preparatory condition.Wherein, preset rules can will meet default bar Accessed duration reaches the video file of predetermined threshold value as original video files to be compressed in the resource pool of part, can also It is using access times are less than the video file of preset times threshold value as treating in preset duration in the resource pool for meeting preparatory condition Original video files of compression, etc..
It is understood that after original video files to be compressed are determined from the resource pool for meet preparatory condition, can To replicate a original video files into caching or other memory spaces, to carry out subsequent treatment to it.
Step S405:Obtain the resolution ratio of original video files.
Step S406:According to preset rules, the resolution ratio of original video files is reduced, generates the video file after compression.
In the present embodiment, step S406, can specifically include:According to default former resolution ratio and resolution ratio after compression Corresponding relation, by the resolution ratio of each original video files be reduced to corresponding to compress after resolution ratio.
Step S407:Video file after storage compression, deletes original video files.
Wherein, step S405~S407 is identical with step S102~S104 in embodiment illustrated in fig. 1 respectively, detailed process Can be with cross-referenced.
From the above, the embodiment of the present invention determines to be compressed original regard from the resource pool for meet preparatory condition Frequency file, then according to the resolution ratio of original video files to be compressed, according to preset rules, reduce dividing for original video files Resolution, the video file after generation compression, the video file after finally storage compression, and delete original video files.With Fig. 1 institutes Show unlike embodiment, embodiment illustrated in fig. 4 can carry out reducing to the video file in the resource pool in cloud storage space divides Resolution processing, therefore the video file in resource pool can be avoided to play slack situation by compression rear video.
In the embodiment shown in fig. 4, before step S406, i.e., according to preset rules, original video files are reduced Resolution ratio, before generating the video file after compression, shown method can also comprise the following steps:
Judge the original video text for being not more than default minimum resolution threshold value in original video files with the presence or absence of resolution ratio Part, if it is present the original video files for being not more than default minimum resolution threshold value to resolution ratio carry out taking out frame processing.
Wherein, it can be 512*288 or other resolution values to preset minimum resolution threshold value.
Specifically, carrying out taking out frame processing to original video files, numerous embodiments can be included, for example, can extract All I frames of original video files, according to default code check, by the video file after all I frames generation compression of extraction.
Can also be that according to preset ratio, the I frames of preset ratio are extracted from original video files, according to default code check, By the video file after the I frames generation compression of extraction.
It is understood that when the resolution ratio of original video files is too small, if carried out again to its resolution ratio at reduction Reason, the definition of the original video files after compression is too low, possibly can not meet the viewing needs of user.Therefore, regarded when original When the resolution ratio of frequency file is too small, it can be carried out to take out frame processing.
In the embodiment shown in fig. 4, step S404, it will meet that all or part in the resource pool of preparatory condition has been deposited The video file of storage is defined as original video files to be compressed, can include:
Step 1:Obtain the last access of each video file stored met in the resource pool of preparatory condition Time, according to current time, it is determined that the current of each video file stored is not accessed duration.
Step 2:It is more than preset duration threshold value with the presence or absence of current not accessed duration in the video file for judging to have stored Video file, if it is present perform step 3, otherwise, perform step 4.
Step 3:The video file that currently not accessed duration is more than preset duration threshold value is defined as to be compressed original Video file.
In actual applications, if the current of all video files in the video file stored is not accessed duration all More than preset duration threshold value, then the video file all stored is defined as into original video files to be compressed.If The current not accessed duration of partial video file in the video file of storage is more than preset duration threshold value, then by this part The video file stored is defined as original video files to be compressed.
If the video text that current not accessed duration is more than preset duration threshold value is not present in the video file stored Part, then in order to compress video memory space, original video files to be compressed are determined using the process of step 4~step 6.
Step 4:The video file stored is sorted according to the currently not accessed order of duration from big to small.
Step 5:Determine that current accessed duration is larger from the video file stored after sequence and take Storage size reaches the target video file of target value.
Wherein, target value is according to video file and default vacating space threshold value or default vacating space ratio-dependent 's.
Specifically, determine that target video file can include a variety of embodiments, for example, with default first numerical value For unit, the storage of larger, the original occupancy of current not accessed duration is determined from the video file stored after sequence Space is the first video file of the first numerical value, estimates the size after the first video file is compressed, and first after being compressed The size of video file vacating space, then compare the size of the vacating space and the magnitude relationship of default vacating space threshold value.
If the former is less than the latter, when determining current not accessed from the video file stored after sequence again The memory space of long larger, original occupancy is the first video file of 2 times of first numerical value.
If the former is more than the latter, and the difference of the size of vacating space and default vacating space threshold value is less than preset difference value Threshold value, then the first video file is defined as target video file.
Step 6:Target video file is defined as to original video files to be compressed.
From the above, in the present embodiment, according to the video text stored in the resource pool for meeting preparatory condition The current of part is not accessed duration, and current not accessed duration in the video file stored is more than into regarding for preset duration threshold value Frequency file is defined as original video files to be compressed, i.e., the video file preferentially infrequently accessed user is defined as original regard Frequency file, the video file that can avoid often accessing user are compressed, therefore can improve Consumer's Experience.
In order to improve the compression efficiency to the video file of resource pool, embodiment illustrated in fig. 4 can also comprise the following steps:
Step 1:Detect in the video file stored with the presence or absence of the first video text for having been subjected to reduction resolution processes Part, if it is present performing step 2, otherwise, do not process.
Step 2:The last access time of each first video file is obtained, according to current time, it is determined that each The current of one video file is not accessed duration.
Step 3:The first video file that currently not accessed duration is more than preset duration threshold value is defined as to be compressed regard Frequency file.
Step 4:Obtain the resolution ratio of video file to be compressed;
Step 5:According to preset rules, the resolution ratio of video file to be compressed is reduced, generates the video file after compression.
Step 6:Video file after storage compression, deletes video file to be compressed.
As shown in the above, in the present embodiment, had been subjected to if existed in the video file stored of resource pool When reducing the first video file of resolution processes, and being more than default in the presence of current accessed duration in the first video file The video file of long threshold value, illustrate that user is not high to the attention rate of this partial video file.At this moment can be by this partial video text Part is defined as video file to be compressed, and pair video file to be compressed determined is compressed processing, judges to be somebody's turn to do without performing again Whether the second value for the storage size shared by video file that the residue of resource pool has stored meets condition, if full Enough, the step of then by original video files to be compressed are determined in the resource pool, so as to improve to resource pool memory space Compression efficiency.
