Detailed Description
In order to explain technical contents, objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
The most key concept of the invention is as follows: and when detecting that the user presses the screen for a long time, acquiring a current video playing picture and identifying the two-dimensional code.
Referring to fig. 1, a method for recognizing a two-dimensional code in a video includes:
when long-press clicking operation is detected, capturing a picture in a video player area to obtain an identification sample;
performing two-dimensional code identification on the identification sample;
and if the identification is successful, displaying the identification result according to a preset feedback mode.

Further, if the duration of the clicking operation is detected to exceed a preset first time, the long-press clicking operation is determined.
Further, after the two-dimensional code recognition is performed on the recognition sample, the method further includes:
and if the identification fails, waiting for a preset second time, and then executing the step of capturing the picture in the video player area again to obtain an identification sample.
According to the description, the success rate of two-dimensional code identification is improved.
Further, after the two-dimensional code recognition is performed on the recognition sample, the method further includes:
and if the long-press clicking operation is detected to stop, stopping performing two-dimensional code identification on the identification sample.
As can be seen from the above description, the flexibility of two-dimensional code recognition is improved.
The invention also proposes a computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps as described above.
Example one
Referring to fig. 2, a first embodiment of the present invention is: a method for identifying two-dimension codes in a video can conveniently identify the two-dimension codes in the video when a mobile device plays the video, and comprises the following steps:
s1: when the video player detects long-press clicking operation, intercepting a picture in the video player area to obtain an identification sample; that is, when the user is detected to press the screen for a long time, the content in the video playing is sampled.
The video player is used as a View (View) in screen display of the mobile device and has the user touch detection capability commonly used for the View. In the SDK (software development tool) of the program, event notifications such as finger-down and finger-up are provided, and when the user presses the screen hold event for more than 1 second, long-press click operation is represented (different operating systems may be slightly different). Therefore, if it is detected that the duration of the click operation exceeds a preset first time (e.g., 1s), it is determined that the click operation is pressed for a long time, and then a picture in the current video player region, that is, the current video frame, is captured as an identification sample. The step is realized by the inside of the video player, so that the user has no perception and the user experience is not influenced.
S2: performing two-dimensional code identification on the identification sample; further, the video player calls a two-dimensional code identification module to perform two-dimensional code identification on the identification sample. The two-dimensional code recognition module is already used as a mature tool and can be directly used in software development.
S3: and judging whether the identification is successful, if so, executing the step S4, and if not, executing the step S5. The reason for the failure in identification may be that there is no two-dimensional code in the picture, the two-dimensional code is unclear, and the two-dimensional code is incorrect.
S4: displaying the recognition result according to a preset feedback mode, namely giving feedback to a user according to needs, for example, if the recognition result is a webpage link, popping a window to prompt whether to open a webpage or directly jumping to a corresponding webpage; and if the identification result is the telephone number, prompting whether to dial the telephone or not and the like.
S5: and after waiting for the preset second time, intercepting the picture in the video player area again to obtain a new identification sample, and performing two-dimensional code identification on the new identification sample, namely returning to execute the step S1. Preferably, the preset second time is 500 milliseconds.
That is, when the user presses the screen for a long time, the video player collects one frame of video picture as an identification sample every 500 milliseconds, and performs two-dimensional code identification. If the identification is successful, feedback is given to the user, and if the identification is unsuccessful, the sampling identification is continued after the next sampling time point is reached.
Further, in the above steps, after detecting that the user performs the long-press click operation, a process of identifying the two-dimensional code is started, in which the user needs to keep the long-press click operation, and if the long-press click operation is detected to stop in the process, the process of identifying the two-dimensional code is stopped. When the identification is successful, the user can release the finger, and the long-press clicking operation is not required to be maintained. And if the two-dimensional code is not recognized all the time, finishing the long-press clicking operation by releasing the finger of the user as an instruction for finishing recognition.
The operation of identifying the two-dimensional code by long pressing the two-dimensional code picture is quite common in picture browsing scenes, and a user can completely master and learn the two-dimensional code, so that the two-dimensional code in the video can be easily adapted and mastered by long pressing and identification, and the method becomes a new interaction habit.
In addition, the player itself already has the function of clicking operation, for example, as follows:
a) the single-click operation is used for displaying and hiding the operation bars at the top and the bottom;
b) double-click operation is used for playing or pausing video;
c) the hold-and-drag is used to adjust brightness, volume or video progress.
According to the above list, long press clicks this interaction has not been used in video players and is also mentioned in the above point as suitable for two-dimensional code recognition.
In summary, in the embodiment, the two-dimension code recognition is triggered by long-time clicking in the video, so that the applicability is strong, the operability is strong, and the recognition can be performed only when the user needs the two-dimension code recognition, so that the flexibility of the two-dimension code recognition is improved.
A specific application scenario of the embodiment is as follows:
1. a video producer of an advertising company places a two-dimensional code picture containing a webpage link at the lower right corner of video content for further popularizing commodities;
2. a user plays an advertisement video by using a player on mobile equipment;
3. when watching a video, a user is interested in advertisement content and wants to know advertisement commodities in detail through the two-dimensional code at the lower right side, and then clicks the long-press video (or player interface) by using fingers to identify the two-dimensional code in the video in the playing process;
4. if the two-dimension code is successfully identified, popping up a dialog box to prompt a user whether the user needs to jump to a specified webpage or not;
5. and clicking the determined button by the user, and jumping to the browser to open the webpage link.
The player is additionally provided with the function of identifying the two-dimension code in the video, a series of operations such as screen capture, code scanning and the like are not required to be performed by a user, the operation steps are simplified, the player only needs to be pressed for a long time, and the interaction experience of the user for identifying the two-dimension code in the video is optimized; meanwhile, the flow of the two-dimension codes in the video is optimized, so that the user is more happy and accustomed to further checking the content of the two-dimension codes in the video, and the popularization and marketing effect is improved.
