Detailed Description
In order to make the technical scheme and advantages of the invention more apparent, the invention is further described in detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a flowchart of a video processing method according to an embodiment of the present invention.
As shown in fig. 1, the method for processing video in the embodiment of the present invention includes the following steps:
and step 10, cutting the original video file into a plurality of slices according to preset time length to form an original slice set.
In the technical scheme of the invention, the original video file can be sliced according to the preset time length, the original video file is cut into a plurality of slices, and the other slices except the last slice have the preset time length (if the total time length of the original video file is integral multiple of the preset time length, the last slice also has the preset time length), therefore, the original slice set can be formed after the plurality of slices are arranged according to the sequence of the playing time.
In addition, in the technical scheme of the invention, the value of the preset duration can be preset according to the requirements of actual application conditions.
For example, in a preferred embodiment of the present invention, the preset duration may be 3 to 10 seconds. Preferably, the preset duration may have a value of 5 seconds.
In addition, as an example, in a preferred embodiment of the present invention, the slice format may be m3u8 format, or other suitable format.
In addition, as an example, in a preferred embodiment of the present invention, the original video file may be sliced using a HTTP Live Streaming (HLS) video slicing method.
And 20, respectively generating N watermark slice sets according to the original slice set and N preset different watermarks.
In the technical scheme of the invention, N different watermarks can be preset; wherein N is an integer greater than 1.
In addition, in the technical scheme of the invention, different watermarks with different numbers can be preset according to different practical application situations.
For example, the value of N may be 2 (i.e. 2 different watermarks: the first watermark and the second watermark may be preset), or may be another suitable value.
In addition, in the technical solution of the present invention, the step 20 can be implemented by various specific embodiments. The technical solution of the present invention will be described below by taking one of the specific implementation modes as an example.
For example, in a preferred embodiment of the present invention, the step 20 may specifically include the following steps:
step 201, setting a first watermark and a second watermark.
Step 202, reading each slice from an original slice set, and adding a first watermark in each slice to generate a first watermark slice set;
step 203, reading each slice from the original slice set, and adding a second watermark in each slice to generate a second watermark slice set.
Through the above steps 201 to 203, when 2 different watermarks (i.e., the first watermark and the second watermark) are preset, 2 watermark slice sets, i.e., the first watermark slice set and the second watermark slice set, may be generated according to the original slice set and the preset 2 different watermarks, respectively. Wherein each slice in the first set of watermark slices has a first watermark and each slice in the second set of watermark slices has a second watermark.
Similarly, when N different watermarks are preset, N watermark slice sets may be respectively generated according to steps similar to the steps 201 to 203, where each slice in the first watermark slice set has a first watermark, each slice in the second watermark slice set has a second watermark, … …, and each slice in the nth watermark slice set has an nth watermark. The detailed implementation is not described herein.
In addition, in the technical solution of the present invention, the specific patterns of the N watermarks may be preset according to the needs of the actual application.
For example, in a preferred embodiment of the present invention, when a first watermark and a second watermark are provided, the first watermark may be a watermark having a first color (e.g., a red logo watermark), and the second watermark may be a watermark having a second color (e.g., a gray logo watermark), the first color and the second color being different colors having a distinguishing degree (e.g., visually recognizable).
In the first watermark slice set and the second watermark slice set generated above, the content, the code stream resolution, the duration, and the like of the corresponding slices (for example, the nth slice in the first watermark slice set corresponds to the nth slice in the second watermark slice set) are completely consistent, and the difference is only that different watermarks are provided.
For example, assuming that the original video file is a.mp4, the first watermark is a red logo watermark, and the second watermark is a gray logo watermark, through the above step 10, a.mp4 may be sliced according to a preset duration, and two slice sets are generated as follows:
first watermark slice set: (ash 1.ts) (ash 2. ts.). (ash n.ts);
second watermark slice set: (red 1.ts) (red 2. ts.). (red n.ts).
Similarly, when N different watermarks are preset, N watermark slice sets may be generated respectively by using different watermarks with N colors of discrimination, which is not described herein again.
And step 30, when the user needs to play the video, acquiring the unique identifier of the user, and converting the unique identifier into a numerical sequence in a preset format.
In addition, as an example, in a preferred embodiment of the present invention, the unique identifier of the User may be a User Identification (UID), or other suitable unique identifier.
In addition, as an example, in a preferred embodiment of the present invention, the value sequence in the preset format may be a binary sequence, or may be another suitable value sequence.
For example, assume that the user's unique identification is a UID, and that the UID is 08301745; if the value of N is 2 and the numerical sequence in the preset format is a binary sequence, the UID (08301745) of the user may be converted into the binary sequence: 00001000001100000001011101000101.
for another example, when the value of N is 8, an octal sequence may be used as the numerical sequence in the preset format, and the unique identifier of the user is converted into the octal sequence.
And step 40, respectively extracting corresponding slices from the N watermark slice sets according to the extraction strategy and the sequence and value of each numerical value of the numerical value sequence, and sequentially combining the extracted slices into a slice sequence.
In the technical scheme of the invention, a corresponding extraction strategy can be preset, so that corresponding slices can be respectively extracted from the N watermark slice sets according to the extraction strategy and the sequence of each numerical value of the numerical value sequence.
For example, in a preferred embodiment of the present invention, when the value of N is 2 and the numerical sequence is a binary sequence, the extraction policy may be:
firstly, extracting m slices from a first watermark slice set or a second watermark slice set as the first m slices of a slice sequence; wherein m is an integer of not less than 0;
and (3) sequentially extracting corresponding slices from the first watermark slice set or the second watermark slice set from the m +1 th slice according to the sequence and the value of each numerical value in the binary sequence.
For another example, in a preferred embodiment of the present invention, the sequentially extracting the corresponding slices from the first watermark slice set or the second watermark slice set according to the order and value of each value in the binary sequence may be:
when one numerical value in the binary sequence is 0, extracting a corresponding slice from the first watermark slice set; when one value in the binary sequence is 1, extracting a corresponding slice from the second watermark slice set;
or the following steps:
when one value in the binary sequence is 1, extracting a corresponding slice from the first watermark slice set; when one of the values in the binary sequence is 0, the corresponding slice is extracted from the second watermark slice set.
For example, when the value of m is n, it indicates that the first n slices of the finally combined slice sequence do not participate in the identification information (preventing the user from clipping the start video when recording).
For example, when the value of m is 1, it indicates that the 1 st slice of the finally combined slice sequence does not participate in the identification information. Thus, 1 slice is extracted from either the first watermark slice set or the second watermark slice set as the 1 st slice of the slice sequence.
Then, assume that the binary sequence is: 00001000001100000001011101000101, corresponding slices can be sequentially extracted from the first watermark slice set or the second watermark slice set according to the above extraction strategy, and the extracted slices are sequentially arranged after the 1 st slice, and combined into a slice sequence, as shown in table 1 below (assuming that the first watermark is a red logo watermark, the second watermark is a gray logo watermark, and the preset duration value is 5 seconds):
TABLE 1
As can be seen from table 1, in the combined slice sequence, the 1 st slice of the slice sequence is used as an initiator and does not participate in the identification information, and the binary sequence corresponding to the UID of the user is identified from the second slice, where the time length of one slice is 5 seconds, the UID of the user needs 33 slices to be completely expressed, each slice has a time length of 5 seconds, and the video time length is 2 minutes and 45 seconds in total.
In addition, as an example, in a preferred embodiment of the present invention, when m slices are extracted from the first watermark slice set or the second watermark slice set, the first m slices may be extracted from the first watermark slice set, or the first m slices may be extracted from the second watermark slice set.
And step 50, playing the corresponding slices in sequence according to the sequence of the slice sequence to form a video stream.
After the slice sequences are combined, the corresponding slices can be played in sequence according to the order of the slice sequences, so that a video stream is formed.
In the technical solution of the present invention, the finally formed video stream is greatly different from the video stream in the prior art, for example, if the value of N is 2, the numerical sequence is a binary sequence, the first watermark is a red logo watermark, and the second watermark is a gray logo watermark, then:
the video stream playing sequence in the prior art is as follows:
1.ts 2.ts 3.ts …… n.ts
the video stream playing sequence formed in the invention is as follows:
ts (Red) 2.ts (Gray) 3.ts (Gray) … … n.ts (Red)
Therefore, according to the video stream playing sequence formed in the invention, if a video is illegally recorded, the source of the illegally recorded video can be known by identifying the watermark identification on the video, calculating the corresponding binary sequence according to the arrangement sequence of the identified watermark identification, and calculating the UID of the corresponding user according to the binary sequence.
Therefore, in the technical solution of the present invention, the method may further include the following steps:
and step 60, identifying the watermarks in all the slices of the video to be detected from the video to be detected, calculating to obtain a corresponding numerical sequence according to the arrangement sequence of the watermarks in all the slices, and calculating to obtain a corresponding user unique identifier according to the numerical sequence.
By executing the step, the user unique identifier can be acquired from the video to be detected, so that the source of the video to be detected can be determined, and subsequent processing (for example, blocking an account of a corresponding user and the like) is performed according to the source of the video.
In summary, in the technical solution of the present invention, after a video file is sliced, N preset visually identifiable watermarks are respectively added to each slice, N watermark slice sets are respectively generated, then a unique identifier of a user is converted into a numerical sequence, corresponding slices are respectively extracted from the N watermark slice sets according to an extraction policy and the numerical sequence, a slice sequence is combined, a video stream is formed, and the unique identifier of the user is incorporated into the formed video. Therefore, when some video streams which are likely to be pirated are required to be detected, the corresponding watermarks can be identified from the video streams to be detected, and the unique user identifier can be calculated according to the identified watermarks, so that pirated screen recording users can be identified, and the video copyright can be effectively protected.
In addition, compared with the commonly used modes of a marquee, fixed display of UID information and the like in the prior art, the technical scheme provided by the invention has extremely high concealment, and can be used for embedding the user information in a concealed manner, so that a pirated video cannot be perceived and damaged by a pirated user, the tracing and backtracking probability of the pirated video can be greatly increased, the grabbing and identification of the pirated screen user can be realized, the cost for selling the video by the pirated screen user again is increased, and the method can play a great positive role in fighting against piracy and maintaining the own rights and interests.
In addition, compared with the prior art, if the technical scheme is used, the cost for cracking and removing the watermark is high, the difficulty is high, and the watermark cannot be removed by modifying the source code and repackaging and packaging even if the html5 webpage end and the android end are used, so that the pirated screen recording user can be effectively identified, the video copyright is effectively protected, and the method is an effective means for attacking the pirated video user.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
