Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for configuring video resolution of a camera according to an embodiment of the present invention. The configuration method of the camera video resolution provided in the embodiment may be executed by a configuration device of the camera video resolution, the configuration device of the camera video resolution may be implemented in a software and/or hardware manner, and the configuration device of the camera video resolution may be formed by two or more physical entities or may be formed by one physical entity. For example, the configuration device of the camera recording resolution can be a mobile phone, an industrial control computer and the like.
In order to facilitate understanding, in the embodiment, the intelligent interactive tablet is taken as an actual carrier, and a detailed process of resolution configuration when the configuration method of the video resolution of the camera is implemented is exemplarily described. The intelligent interactive panel can be an integrated device which controls the content displayed on the display panel and realizes man-machine interaction operation through a touch technology, and integrates one or more functions of a projector, an electronic whiteboard, a curtain, a sound box, a television, a video conference terminal and the like.
In the existing intelligent interactive flat panel, in order to meet various requirements of field interaction and remote interaction, one or more cameras are generally configured for each intelligent interactive flat panel in an integrated manner, in the function implementation process of the intelligent interactive flat panel, the resolution corresponding to the integrated cameras is generally saved in a default configuration file manner, and when the original integrated cameras are used for video acquisition, the video acquisition task can be completed directly through the resolution recorded in the default configuration file. But when the integrated camera of original dress broke down, perhaps when carrying out interactive activity design based on intelligent interaction flat board the integrated camera of original dress can not realize established design demand, then need external camera to realize various video acquisition tasks. Generally speaking, the external camera is a USB camera, but when the resolution supported by the external camera is not matched with the original default resolution of the intelligent interactive tablet, the situation that the external camera cannot be used when plugged can occur. Aiming at the condition that the camera cannot be normally used, the technical scheme is provided to realize plug and play of any external camera.
Specifically, referring to fig. 1, the method for configuring video resolution of a camera specifically includes:
and S101, confirming that a camera opening instruction is received, and reading a video resolution list of the camera.
The camera opening instruction is used for instructing the camera to open and carry out video acquisition, and in the specific implementation process, the camera opening instruction is sent out through the APP that user operation carried out video acquisition. For example, a user clicks a camera icon of the terminal device to enter a camera operation interface, confirms that video recording starts, detects that the operation of starting video recording confirms that a camera opening instruction is received, that is, enters a camera APP of the terminal device to start video acquisition and can confirm that the camera opening instruction is received. For another example, some social APPs, short video APPs, and communication APPs may record videos for release or transmission, and the camera start instruction may also be determined as received when the video recording start operation is detected in the various video-recordable APPs, that is, the camera start instruction may also be determined as received when the user starts any video acquisition by himself entering the APP installed by the user. In addition, for the remote video conference, a camera is also required to be called to realize the collection and transmission of video data (namely, a video recording process exists), and when the operation of starting the remote video conference is detected, the camera opening instruction can be confirmed to be received.
The recording resolution list is stored in the storage module in the USB camera, and at least one recording resolution (for example, 1280 × 720, 1920 × 1080) supported by the camera is recorded in the recording resolution list, and the recording resolution list is stored in the storage module in the USB camera by a common name, a common format, and/or a common storage path. When the USB camera is in a connection state with the terminal equipment through the USB interface, as long as the terminal equipment confirms that the camera opening instruction is received, the storage module in the USB camera is accessed, and the video resolution list is obtained.
And S102, generating a video configuration file according to the video resolution list, and setting a configuration updating identifier as an updating resolution configuration.
After the video resolution list is read, a new video configuration file can be generated by combining the video resolution supported by the USB camera and the video resolution supported by the image processing of the terminal device, in which the recorded video resolution can be supported by both the USB camera and the image processing of the terminal device, but the video resolution recorded in the video configuration file is not directly saved in the memory, but is used when a specific video instance is executed.
In the scheme, after a camera opening instruction is received, the following video recording process needs to complete the video recording process through the video recording resolution recorded in the video recording configuration file.
And step S103, reading the configuration updating identification when the video example is obtained.
In the video processing process of the terminal equipment, the video of the android equipment mainly provides four high-power energy through libMedia, wherein the four high-power energy comprises video component searching, video capturing, video compressing and video playing, and the interface classes corresponding to the four high-power energy are CLASS XVI DEO _ CLASS CxSystemDeviceFind, CLASS XVIDEO _ CLASS CxDSVideoCapture, CLASS XVIDEO _ CLASS CxDSVideoCompressor and CLASS XVIDEO _ CLASS CxDSVideoPlayer in sequence. The four functions can be realized, and then the recording of a video segment is completed. The configuration of the correct video resolution is based on the implementation of the above four functions, namely the completion of video recording. In the example of video recording, the configuration update flag may be read first by calling any of the above interface classes, so as to confirm the video recording resolution that should be adopted.
And step S104, when the configuration updating mark is the resolution updating configuration, updating the resolution configuration according to the video configuration file.
When the video recording example is executed specifically, it is first determined whether the resolution configuration needs to be updated in the current state according to the read configuration update identifier, if it is determined that the resolution configuration needs to be updated currently according to the configuration update identifier, the video recording configuration file in step S103 is obtained, the resolution recorded in the video recording configuration file is configured to be the currently usable resolution, the resolution recorded in the video recording configuration file is firstly the usable resolution of the camera and is also the resolution supported by the system in the terminal device, and when the video recording example is executed based on the resolution in the video recording configuration file, normal video recording (i.e., video data acquisition) can be realized.
In terms of equipment operation, a user only needs to insert the USB camera into the USB interface of the terminal equipment, and then does not need to perform any manual operation related to configuration, and only needs to confirm that the camera is used for recording. Through the design of setting and reading time of the configuration updating identification and corresponding response, the plug-and-play effect of the USB camera is integrally presented to a user, especially for the user who has no concept of abnormity after the USB camera is inserted, the operation trouble of using the USB camera can be effectively reduced, and the use friendliness of the terminal equipment is improved.
Reading a video resolution list of the camera by confirming that a camera opening instruction is received; generating a video configuration file according to the video resolution list, and setting a configuration updating identifier as an updating resolution configuration; when a video instance is acquired, reading the configuration updating identification; and when the configuration updating mark is the resolution updating configuration, updating the resolution configuration according to the video configuration file. The video resolution list can be updated in real time before the video instance is executed based on the resolution reading and configuration of the configuration updating identification, the acquired resolution can be supported by the current camera, and plug-and-play and comprehensive compatibility of the external camera are realized.
Example two
Fig. 2 is a flowchart of a method for configuring video resolution of a camera according to a second embodiment of the present invention. The present embodiment is embodied on the basis of the above-described embodiments.
Specifically, referring to fig. 2, the method for configuring video resolution of a camera provided in this embodiment specifically includes:
step S201, reading a configuration file of an original resolution pre-stored in the system into a memory.
The terminal equipment aimed at by the scheme is mainly an android system, and in the existing camera video recording scheme, a video resolution list recorded in a default configuration file is directly read from the android system after a camera is opened, and one video resolution is selected from the video resolution list for video recording. Even after a new camera is accessed, the android system can still use the equipment identifier of the original camera to obtain a video resolution list, which is equivalent to the video resolution list supported by the old camera, and if the new camera does not support a certain video resolution in the video resolution list, an error is reported when the new camera selects the video resolution for recording, so that normal recording cannot be performed.
The configuration of the video resolution is realized based on the original resolution configuration file, and as a whole, the original resolution configuration file is prestored in the android system, and all video resolution configurations supported by the android system are listed in the original resolution configuration file.
And S202, confirming that a camera opening instruction is received, and reading a video resolution list of the camera.
After confirming that the camera opening instruction is received, a video resolution list stored in the new camera device is read through driving, wherein the video resolution list is not directly applied to a video example after being read, but a data processing process of resolution related parameters in a subsequent step is required to be carried out based on the video resolution list.
Step S203, generating a video configuration file according to the video resolution list, and setting a configuration updating identifier as an updating resolution configuration.
In a specific implementation process, the video configuration file may be generated in the following manner: and comparing the video resolution list with an original resolution configuration file prestored in the system, and deleting the resolutions which do not appear in the video resolution list in the original resolution configuration file to be used as a video configuration file. That is to say, in the process of generating the video configuration file, it is necessary to traverse the resolution parameters recorded in the original resolution configuration file, that is, to read the resolution parameters recorded in the original resolution list in sequence, compare them with the video resolution list stored in the USB camera one by one, determine whether they exist in the video resolution list, delete the resolution parameters that are not recorded in the video resolution list, and after the traversal comparison ends, additionally store the original resolution configuration file to obtain the video configuration file.
The configuration update flag is a flag bit for indicating whether to update the resolution configuration, and may be identified by a custom system attribute, for example, by "sys _ graphic.
And step S204, reading the configuration updating identification when the video example is acquired.
The method comprises the steps that a video recording example confirms that a video recording task exists after a camera opening instruction is confirmed to be received, the video recording task is completed through the video recording example, before the video recording example is executed, the specific resolution ratio of video recording needs to be confirmed, the resolution ratio of video recording needs to be judged in advance whether the resolution ratio information in a memory needs to be updated or not instead of directly reading the existing resolution ratio information in the memory, and the specific judgment process is completed through reading a configuration updating mark. For example, based on the custom system attribute in step S203, each time the MediaProfiles instance in libMedia is acquired, the value of the pre-agreed custom system attribute "sys _ graphic.cam _ profile _ modify" is read. The native libmedia _ jni records the MediaProfiles instances by using the global variable, so that the updating instantaneity of the MediaProfiles instances cannot be realized, and the MediaProfiles instances are acquired in real time when being used.
Step S205, when the configuration update flag is the update resolution configuration, replacing the video configuration file with the original resolution configuration file in the memory.
If the value of the custom system attribute "sys _ graphic, cam _ profile _ modify" is true, it indicates that the original resolution configuration file existing in the memory needs to be updated to complete the update of the resolution configuration, and the update process is implemented by re-reading the video configuration file generated in step S203. When the configuration file needs to be read again, the creationinstance of the configuration file is read again by using creationstandranslacefromxllfile of MediaProfiles, and then the new instance is returned to libmedia _ jni for use.
Furthermore, after the first video recording task is completed after the power is turned on, the video recording instance may end the task, and at this time, the power is turned on and the resolution information in the memory is read and changed when the first video recording instance is executed, and the execution is still started from step S202 when a new video recording task is executed subsequently, that is, after the camera turn-on instruction is confirmed to be received, the video recording resolution list of the camera is read again, and the resetting process of the subsequent video recording resolution is completed.
Step S206, resetting the configuration updating mark from the updating resolution configuration to the maintaining resolution configuration.
In the execution process of the current video recording task, after the video recording resolution is reset based on the currently accessed USB camera, the same resolution configuration may be used in each function implementation process subsequently, and after the configuration update identifier is reset to the resolution retention configuration (i.e., reset from "true" to "false"), the resolution configuration is not changed any more, i.e., the second resolution configuration is not performed in the execution process of a single video recording task.
And step S207, when the configuration updating mark is that the resolution configuration is kept, executing the video recording example according to the current resolution configuration.
When the configuration updating mark is used for keeping the resolution configuration, or after the resolution configuration is updated, reading a currently stored video resolution list from the memory and returning the video resolution list to an upper layer for use, and selecting a proper resolution from the video resolution list for video recording.
