- the controller 250 may adopt a corresponding screen recording mode for the detected video data type. If the currently displayed video data type is standard signal video, the video data before decoding can be directly copied, thereby generating a screen recording file and reducing the load of the controller 250 . For example, when a user watches live content through a digital TV signal, the controller 250 can detect that the current video data type is a standard signal video, so the method of recording TS can be adopted, that is, before the video data enters the decoder for decoding, the video The data is stored, so that it is not necessary to repeat decoding and re-encoding, and the load on the controller 250 is reduced.
- the controller 250 may start a screen capture program to continuously capture the current video display screen frame by frame, thereby obtaining multiple video display screen images.
- the controller 250 then combines multiple video display images to form video stream data, and finally converts the formed video stream data into a screen recording file by performing processing such as hybrid encoding.
- processing such as hybrid encoding.
- the controller 250 controls to start the screen capture program, and captures the content of the current video display screen frame by frame, so as to form multi-frame images with a time sequence relationship, so as to generate a screen recording file.
- the type of the current video data is first judged, so that when the video data is a standard signal video, a screen recording file is directly generated by copying the video data before decoding;
- the video data type is non-standard signal video
- the video image is acquired frame by frame by intercepting the currently displayed image to generate a screen recording file.
- the screen recording method can adopt different screen recording methods according to different video data types, adapt to all displayed images, and can reduce the load of the controller during screen recording.
- only the screen content can be recorded for a part of the display screen. For example, when recording the UI interface, since there is no relevant sound information, only the video content can be recorded.

- audio data can also be recorded. Since most of the display images of the standard signal video are specific video playback images, the controller 250 can also acquire audio data while acquiring video data. Therefore, the recorded audio data can be obtained by directly copying the audio data corresponding to the playing video.
- the screen recording method when it is detected that the current video data type is a non-standard signal video, it is necessary to perform frame-by-frame capture of the current display image to form a video stream composed of a plurality of captured images. Therefore, in order to enable the captured image to form a smooth video picture, if the picture type is a non-standard signal video, the screen recording method further includes the following steps:

- the OSD (On Screen Display) layer is the topmost layer of the picture that the display device 200 can present.
- the OSD layer may include content such as characters, graphics, and images that can be directly displayed on the display 275 . By capturing the images of the OSD layer, an image with the same content displayed on the display 275 can be captured, thereby realizing the recording function of all the displayed images.
- the frame rate corresponding to the generated screen recording file can be set to a higher value, and the corresponding frequency of capturing the video display screen is also correspondingly increased. That is, if the hardware conditions permit, the sampling frequency of the interception process may be set to be greater than the valid frame data.
- the actual video display screen capture frequency may be 60 frames per second, thereby generating screen recording data with a frame rate of 60 Hz.
- the sampling frequency when capturing a picture can also be automatically adjusted according to the operating load of the controller 250 .
- the sampling frequency of each screen recording can be adjusted as the processing load changes, so that a smoother screen recording video can be obtained without affecting the playback process.
- the step of capturing the displayed picture frame by frame at the OSD layer further includes:
- the CPU usage rate of the controller 250 may be detected first, and the CPU usage rate value obtained by the detection may be judged. If the usage rate is less than or equal to the preset judgment threshold, it is determined that the current processing load of the controller 250 is light, so a higher sampling frequency can be used, that is, the display screen can be captured frame by frame at the OSD layer according to the refresh frequency of the display 275 . If the usage rate is greater than the preset judgment threshold, it is determined that the current processing load of the controller 250 is heavy, so a lower sampling frequency can be used, that is, the display screen can be captured frame by frame at the OSD layer according to the sampling frequency corresponding to the valid frame data. For example, the preset judgment threshold is 50%.
- the OSD layer can be displayed one by one according to the refresh frequency of the display 275 of 60 Hz. Frame capture the display screen to obtain a screen recording file with a frame rate of 60Hz.
- the display screen is captured frame by frame at the OSD layer according to the sampling frequency corresponding to the valid frame data of 24 Hz to obtain the frame rate 24Hz screen recording file.
- the adjustment of the sampling frequency may also be comprehensively adjusted with reference to other hardware load conditions other than the usage rate of the controller 250 .
- the available memory space For example, the available memory space, the remaining space of the memory 260, the main frequency of the CPU, and the like.
- a score value may be determined according to a preset weighting algorithm, and the interception frequency may be determined according to the magnitude relationship between the score value and the corresponding judgment threshold.
- the smoothness of the recorded video is guaranteed.
- a screen recording file with a higher frame rate can be generated when the hardware conditions permit, and the quality of the screen recording video can be further improved.
- the display device 200 may generate a screen recording file by directly copying the video data before decoding.
- the screen recording method further includes:
- standard signal data can be obtained, where the standard signal data includes video data and audio data.
- the controller 250 can acquire all the video data, audio data and other related data obtained after demultiplexing, such as subtitles such as subtitle files.
- register the data acquisition call task in the operating system and use the data acquisition call task to gradually add standard signal data to the screen recording data package to collect the acquired standard signal data.

图6为根据本申请一个或多个实施例的录屏分享方法的流程示意图。结合图6,录屏方法包括以下步骤:
S610:接收用户通过按压遥控器上的截图按键发出的启动指令。
在一些实施例中,遥控器上设置有特定按键,该特定按键可以是截图按键,或者,遥控器中某一特定按键绑定截图功能,例如,将喜爱键或者直播键绑定截图功能。以特定按键是截图按键为例,在显示设备200正常开机状态时,用户可随时通过按压截图按键发出启动指令,控制器250在接收到该启动指令之后,相应的进行截图或录屏。
S620:在所述截图按键的按压时长超过预设启动时长时,根据所述启动指令录制显示器所显示的显示界面并生成录屏文件。
在一些实施例中,在显示设备200中设置有预设启动时长,通过截图按键的按压时长与预设启动时长做比较,来确定下一步是根据启动指令进行截图还是根据启动指令进行录屏,其中,截图按键的按压时长指的是用户将截图按键按下直至松开截图按键之间时长。
在一些实施例中,在所述截图按键的按压时长未超过预设启动时长时,根据所述启动指令对显示器所显示的显示界面截图并生成截屏图像。例如,将预设启动时长设置为300毫秒,当用户通过显示器275正在观看视频时,若是想要保存当前显示器275所展示的内容,即可通过遥控器按下截图按键。当用户开始按压截图按键时,就已经向显示设备200发送了启动指令,控制器250在判断其按压时长没有超过300毫秒时,也就是用户按下截图按键,并于300毫秒内松开了截图按键,则可认为用户仅是想要保留显示器275的当前显示界面,此时,控制器250根据启动指令对显示器275所显示的显示界面截图并生成截屏图像。
在一些实施例中,在所述截图按键的按压时长超过预设启动时长时,根据所述启动指令录制显示器所显示的显示界面并生成录屏文件。例如,将预设启动时长设置为300毫秒,当用户通过显示器275正在观看视频时,若是想要录制当前播放的内容,则可以按下截图按键,并进行持续性按压。当用户开始按压截图按键时,就已经向显示设备200发送了启 动指令,控制器250在接收到启动指令后,首先对显示器275所显示的显示界面截图并生成截屏图像,若是控制器250在判断其按压时长超过300毫秒时,则可认为用户是想要进行录屏,此时,控制器250录制显示器275所显示的显示界面并生成录屏文件。
在一些实施例中,控制器250还被配置为获取所述截屏图像中的人物识别结果,控制所述显示器在显示界面展示出所述人物识别结果。
在一些实施例中,无论是否进行录屏,显示设备200均可以先生成截屏图像,若是录屏的话,就在截屏图像的基础上继续录制显示界面,从而生成录屏文件。显示设备200在接收到用户输入的启动指令后,需要向用户反馈一部分数据,通过显示器275进行展示,以使用户得知显示设备200进行截图或者录屏操作。
在一些实施例中,控制器250在获取到截屏图像后,将截屏图像上传至服务器400,服务器400响应于控制器250上传的截屏图像,并基于图像识别技术对截屏图像进行人物识别。服务器400基于截屏图像获取到图像中人物的头像缩略图及对应的人物标识。例如,对于截图中存在的影视明星的名字,其人物标识就是该人物的名字。对于用户自己录制的视频来说,截图中存在的普通人,其人物标识可以是对应的帅哥、美女、老奶奶、小学生等。服务器400将获取的人物识别结果,即人物的头像缩略图及对应的人物标识,反馈至显示设备200中,控制器250控制显示器275在显示界面的浮层上展示出相应的人物识别结果。
<生成录屏文件>
图7为根据本申请一个或多个实施例的生成录屏文件方法的流程示意图。结合图7,通过步骤S710至步骤S730对生成录屏文件进行了说明:
S710:在所述截图按键的按压时长超过预设启动时长时,以控制器接收到启动指令的起始时刻为起始点开始录制所述显示界面。
在一些实施例中,用户通过按压截图按键即向显示设备200发送了启动指令,控制器250根据启动指令对显示器当前显示的显示界面进行截图,生成截屏图像。在进行截图操作的同时进行计时,再判断用户按压截图按键的时长,当截图按键的按压时长超过预设启动时长时,控制器250以接收到启动指令的起始时刻为起始点开始录制所述显示界面,也就是说,控制器250以截屏图像为起始帧开始录制所述显示界面。
S720:控制所述显示界面上展示出录屏控件,所述录屏控件用于指示录屏时长,或者用于指示正在录屏中。
在一些实施例中,图8为根据本申请一个或多个实施例的生成录屏文件的显示界面图。由图8所示,当控制器250以接收到启动指令的起始时刻为起始点开始录制所述显示界面时,并控制在显示界面上展示出录屏控件,通过录屏控件向用户提示录制的时长是多久。图8的左上角展示出“录屏中00:05”,其意义即为录屏文件已经录制了5秒。
在一些实施例中,图9为根据本申请一个或多个实施例的另一生成录屏文件的显示界面图,图10为根据本申请一个或多个实施例的另一生成录屏文件的显示界面图,参考图9和图10,通过录屏控件向用户提示显示设备200现在正在录屏中,一个左上角展示出的录屏控件为“录屏”,另一个左上角展示出录屏控件为“·录屏”,通过两个状态下的录屏控件的交替出现,也就是说,通过录屏控件闪烁交替的两种状态,来提示用户显示设备200现在正在录屏中。
S730:在接收用户通过松开所述截图按键发出的停止指令时,或者在所述按压时长超 过预设上限时长时,停止录制所述显示界面并生成录屏文件。
用户通过持续性按压遥控器上截图按键,用来进行录屏,当录制过程中,用户发现已经将自己所想录制的片段录制完成,则可通过松开截图按键停止录屏,也就是说,用户松开截图按键相当于向控制器250发送了停止指令,控制器250在接收到停止指令之后,停止对显示器275当前显示界面的录制,并生成录屏文件。
在一些实施例中,用户通过持续性按压遥控器上截图按键,用来进行录屏,在录制过程中,控制器250一直进行计时,当截图按键的按压时长,也就是录屏文件的录制时长超过预设上限时长时,控制器250停止录制显示器275的当前显示界面,并生成录屏文件。其中,预设上限时长可以设置为60秒,其可以根据显示设备存储空间的大小进行设置,在此不做限定。
<不合格录屏文件>
在一些实施例中,当控制器250以接收到启动指令的起始时刻为起始点开始录制所述显示界面之后,根据控制器250的计时,在所述按压时长未超过预设下限时长时,停止录制所述显示界面并生成不合格录屏文件,所述不合格录屏文件是指未超过预设下限时长的按压时长内所生成的录屏文件。也就是说,当用户按下遥控器的截图按键后,按压时长超过了预设启动时长,控制器250开始录制文件,但是用户随后就松开了截图按键,从按压截图按键到松开截图按键之间的时长还未达到预设下限时长,导致录屏文件所录制的时间较短,那么控制器250在停止录制显示界面之后生成不合格录屏文件。例如,用户按下截图按键超过300毫秒,控制器250开始录屏文件的录制,当按压时长到达2秒后,用户松开了截图按键,此时控制器停止录屏文件的录制,并将生成的录屏文件视为不合格录屏文件。
在一些实施例中,生成不合格录屏文件之后,控制器控制所述显示界面展示第一提示框,所述第一提示框用于指示录屏文件不合格。图12为根据本申请一个或多个实施例的生成不合格录屏文件的显示界面图,参考图12,第一提示框中可以设置有“录屏时间太短无法播放,需要重新录制”的文字提醒。由于不合格录屏文件无法进行播放,也没有保留价值,控制器250可以删除所述不合格录屏文件,以免其占用存储空间。通过预设下限时长能够避免用户原本是想要进行截图,结果按压时长稍微超过了预设启动时长进行误录制的情况。另外,还能够避免即使是用户原本想要录屏,但在后期播放录制文件时,由于录屏时间较短,录屏文件一闪而过,使得用户误以为显示设备出现播放故障的情况。
<文件的存储>
在一些实施例中,为了防止生成录屏文件之后,显示设备200中没有足够的存储空间来存储录屏文件,在开始录屏前,控制器250被配置为需要先查看一下存储空间余量。显示设备200中存储有预设余量,该预设余量大于等于在预设上限时长下所生成的录屏文件的大小。控制器250查看磁盘中的存储空间余量后,判断存储空间余量与预设余量的大小。在存储空间余量超过预设余量时,也就是说,存储空间余量还能够存储至少一个在预设上限时长下所生成的录屏文件,此时,根据所述启动指令录制所述显示界面并生成录屏文件。
在一些实施例中,控制器250查看磁盘中的存储空间余量后,判断存储空间余量与预设余量的大小。在存储空间余量未超过预设余量时,若所述存储空间内存储有历史录屏文件,则删除所述历史录屏文件,并根据所述启动指令录制所述显示界面并生成录屏文件。也就是说,当控制器250查看到存储空间余量不能够存储一个在预设上限时长下所生成的 录屏文件时,控制器250需要进一步查看存储空间中所存储的文件,对于之前生成过的历史录屏文件来说,用户可能已经进行了分享,继续存储历史录屏文件的意义不大,所以,控制器250可以将历史录屏文件删除,以使磁盘中的存储空间足以存储新的录屏文件。需要说明的是,在删除历史录屏文件时,可以按照时间先后进行文件的删除,例如,先删除录制时间最早的历史录屏文件。
在一些实施例中,控制器250查看磁盘中的存储空间余量后,判断存储空间余量与预设余量的大小。在存储空间余量未超过预设余量时,若所述存储空间内未存储有历史录屏文件,则弹出第二提示框,所述第二提示框用于提示用户存储空间已满无法录屏。也就是说,当控制器250查看到存储空间余量不能够存储一个在预设上限时长下所生成的录屏文件时,控制器250需要进一步查看存储空间中所存储的文件,若是存储空间中并没有历史录屏文件,则显示设备200中无法继续存储新生成的录屏文件,那么此时控制器250需要通过第二提示框提示用户存储空间已满无法录屏。
<录屏文件分享>
S630:在保存所述录屏文件后,根据所述录屏文件的保存路径生成分享控件,其中,所述分享控件用于将所述录屏文件进行分享。
局域网内分享:
在一些实施例中,控制器250在根据启动指令生成录屏文件之后,将所述录屏文件保存至本地存储空间,也就是本地磁盘中。根据录屏文件的保存路径和显示设备的域名,控制器250生成字符串,并进一步根据字符串生成二维码。该二维码作为分享控件,将录屏文件进行分享。用户想要从显示设备200中获取到该录屏文件时,可通过手机、iPad及笔记本等带有摄像头的移动终端扫描二维码,控制器250通过判断显示设备200和移动终端是否位于同一局域网内,若是显示设备200和移动终端在同一局域网内,那么控制器250直接通过MQTT(Message Queuing Telemetry Transpor、消息队列遥测传输)、蓝牙等通信方式,将录屏文件传输给移动终端。若是显示设备200和移动终端不在同一局域网内,则控制器250通过显示器275弹出第三提示框,用于提示用户需要将移动终端连接至显示设备200所在的局域网内,然后再进行录屏文件的获取。
局域网内录屏文件分享,可以理解为移动终端与显示设备200通过一根网线连接,移动终端若想获取到存储在显示设备200上的录屏文件,则需要通过二维码确定显示设备当前的域名以及录屏文件的保存路径,当移动终端想要读取文件时,只需在同一局域网内将录屏文件进行传输即可。
非局域网内分享:
在一些实施例中,控制器250在根据启动指令生成录屏文件之后,将所述录屏文件上传至服务器400,以使所述服务器400将所述录屏文件保存至数据库。服务器400在存储完所述录屏文件之后,将录屏文件的存储地址反馈至显示设备200。控制器250基于生成截屏图像的时间戳、服务器域名、显示设备标识以及所述存储地址提取出字符串,并根据字符串生成二维码。该二维码作为分享控件,将录屏文件进行分享。用户想要从显示设备200中获取到该录屏文件时,可通过手机、iPad及笔记本等带有摄像头的移动终端扫描二维码,服务器400基于移动终端的请求,获取到相应的录屏文件并反馈至移动终端,实现录屏文件的分享。
非局域网内录屏文件分享中,移动终端若想获取到存储在服务器400上的录屏文件, 则需要通过生成截屏图像的时间戳获取刚开始录屏文件生成的时间点,通过服务器域名获取要去哪台服务器访问,通过显示设备标识明确具体是哪台显示设备所生成的录屏文件,通过存储地址获取具体的录屏文件,当移动终端想要读取文件时,通过扫描二维码向服务器请求录屏文件即可。
S640:控制所述显示器在显示界面上展示出所述分享控件。
在一些实施例中,显示设备200生成的录屏文件,能够支持显示设备200的本地播放,还能够通过移动终端扫描分享控件进行分享,当移动终端获取到录屏文件之后,还能够在好友之间互相分享。由于显示设备200在生成截屏图像或者录屏文件时,均不会干扰到显示设备200内容的播放,并且不会干扰到用户对显示设备200的其他操作。用户对显示设备200进行操作时,可以通过语音控制显示设备200。
图11为根据本申请一个或多个实施例的显示器弹出浮层的显示界面图。由图11所示,显示设备200在播放内容的过程中,若是分享控件已经生成,则控制所述显示器275在当前显示界面上弹出浮层,在该浮层中设置有分享区域,分享区域中展示有二维码,图11中分享区域的背景可采用截屏图像,将二维码浮于截屏图像上方。另外,在二维码旁边设置有“扫码获取录屏文件”的文字提示,并且设置有“‘OK’放大截图”的文字提示,当用户想要将分享区域中的截屏图像进行放大时,可通过遥控器上的“OK”按键实现。
在一些实施例中,所述浮层还包括内容识别区域,通过所述内容识别区域展示所述人物识别结果。如图11中所示,通过内容识别区域展示出人物的头像缩略图及对应的人物标识。当用户通过“OK”按键放大截屏图像后,能够便于得知人物识别结果是从哪个截图中获得的,并且能够仔细看清头像缩略图所对应的人物。
在一些实施例中,启动录屏的方式可以是通过用户界面中的控件来实现,图13为根据本申请一个或多个实施例的显示功能菜单的界面图,参考图13,用户可以通过遥控器的特定按键,例如“菜单键”,“语音键”,向电视发送显示功能菜单指令,电视接收并响应该指令,在用户界面上呈现出功能菜单。例如,在图13中,功能菜单显示在界面的左下方,包括录屏控件1301,截屏控件1302,查看控件1303等。当用户通过遥控器方向按键移动焦点到录屏控件1301上,并按确认键,此时,电视接收录屏指令,控制器则控制电视录制显示器所显示的显示界面并生成录屏文件。
在一些实施例中,启动录屏的方式还可以是用户通过语音指令,例如“启动录屏”,电视接收该语音指令后,启动录屏程序并执行录屏操作。
在一些实施例中,当用户操控焦点选择录屏控件1301后,在该控件的上方会产生时间提示信息,例如,图14为根据本申请一个或多个实施例的录屏时间提示的界面图,参考图14,显示时间00:05,代表正在执行录屏操作,执行时间为00:05。其中,提示录制时间的位置及形式,可以图8-图10给出的形式,当然本领域技术人员可以根据设计需要,给出其他的形式。
在一些实施例中,用户再次操控焦点选择录屏控件1301,控制器接收到指令后则控制电视停止录屏操作,并保存录屏文件。此时,图15为根据本申请一个或多个实施例的录屏保存/删除的界面图,参考图15,显示界面中可以提示用户是否保存或者删除该录屏文件,当用户操控焦点点击“是”控件后,则保存录屏文件,反之,当用户操控焦点点击“否”控件后,则删除录屏文件。
在一些实施例中,用户也可以通过语音指令,例如“停止录屏”,电视接收该语音指 令后,停止执行录屏操作。
在一些实施例中,开始/停止录屏的方式可以是通过用户界面中的“开始”/“停止”控件来实现,这里不再给出示例图。
在一些实施例中,参考图13-图15,截屏控件1302用于对当前的显示界面进行截图。当用户操控焦点点击该截屏控件1302后,电视的控制器执行截图操作,然后显示界面则提示是否保存截图文件,图16为根据本申请一个或多个实施例的截屏保存/删除的界面图,参考图16。用户通过选择“是”/“否”控件来执行保存/删除操作。这里不再展开说明。
在一些实施例中,用户也可以通过语音唤醒截屏功能,例如,电视接收并识别“截屏”语音指令,控制器则控制电视执行截屏操作。
在一些实施例中,参考图13-图16,查看控件1303用于对电视保存的文件进行查看,包括录屏文件、截屏文件等。用户可以通过遥控器焦点选择该控件后,电视界面则跳转到文件查看的界面,图17为根据本申请一个或多个实施例的文件查看的界面图,参考图17。文件可以以缩略图的形式呈现,排序方式可以是时间,也可以是名称等。录屏文件和截屏文件可以是混合显示,也可以是分开显示。本申请不限定文件的显示方式。
在一些实施例中,用户也可以通过语音执行进行文件的查看,例如,电视接收并识别“查看文件”的语音执行,控制器则控制电视界面跳转到图17所示的界面。无论是否进行录屏,显示设备均可以先生成截屏图像,若是录屏的话,就在截屏图像的基础上继续录制显示界面,从而生成录屏文件。控制器在获取到截屏图像后,将截屏图像上传至服务器,服务器响应于控制器上传的截屏图像,并基于图像识别技术对截屏图像进行人物识别。具体介绍请参考前文。
在一些实施例中,录屏文件所录制的时间较短,那么控制器在停止录制显示界面之后生成不合格录屏文件。图18为根据本申请一个或多个实施例的生成不合格录屏文件的显示界面图,参考图18,在显示界面上提示“录屏时间太短无法播放,需要重新录制”。对录屏或者截屏前,显示设备需要判断下存储空间余量,保证有足够的余量前提下,才能执行录屏或者截屏操作,具体的判断方式参考前文描述。
在一些实施例中,控制器查看磁盘中的存储空间余量后,判断存储空间余量与预设余量的大小。在存储空间余量未超过预设余量时,若所述存储空间内未存储有历史录屏文件,则弹出第二提示框,所述第二提示框用于提示用户存储空间已满无法录屏,图19为根据本申请一个或多个实施例的存储空间已满的显示界面图,具体可以参考图19。
在一些实施例中,在保存所述录屏文件后,根据所述录屏文件的保存路径生成分享控件,其中,所述分享控件用于将所述录屏文件进行分享,并且控制所述显示器在显示界面上展示出所述分享控件。具体的实现步骤参考前文描述。无论显示器显示的内容是静态画面还是动态画面,控制器均能够基于用户所发出的识别指令进行录屏,并且录屏文件不仅能够在显示设备上进行本地播放,还能够通过分享控件分享至其他设备中,大大增加了用户对显示设备的使用体验感受。
在一些实施例中,本申请还提供了录屏分享方法,所述方法包括:显示设备200中的控制器250接收用户通过按压遥控器上的截图按键发出的启动指令。控制器250判断用户对截图按键的按压时长与预设启动时长的大小,在所述截图按键的按压时长超过预设启动时长时,根据所述启动指令录制显示器所显示的显示界面并生成录屏文件。控制器250将所述录屏文件进行保存,并在保存所述录屏文件后,根据所述录屏文件的保存路径生成分 享控件,其中,所述分享控件用于将所述录屏文件进行分享。控制器250控制所述显示器275在显示界面上展示出所述分享控件,以便用户通过移动设备获取录屏文件进行分享。
在一些实施例中,本申请还提供一种录屏分享方法,所述方法包括:
接收启动指令,根据所述启动指令录制显示器所显示的显示界面并生成录屏文件;
在保存所述录屏文件后,根据所述录屏文件的保存路径生成分享控件,其中,所述分享控件用于将所述录屏文件进行分享;
控制所述显示器在显示界面上展示出所述分享控件。
具体的录屏分享方法可以参考上文,这里不再赘述。本申请能够实现在用户对显示设备中显示器所显示的内容感兴趣时,可向显示设备发送启动指令,显示设备中的控制器在接收到启动指令后,控制器录制显示器所显示的显示界面并生成录屏文件,该录屏文件即为用户感兴趣的显示器所显示的内容。控制器将所述录屏文件进行保存,并根据所述录屏文件的保存路径生成分享控件,在显示界面上通过浮层将分享控件进行展示,用户可通过显示器所展示的分享控件获取到录屏文件。
在一些实施例中,本申请还提供一种屏幕录制方法,该方法可以配置在显示设备200中,用于在需要进行屏幕录制时,由控制器250调用运行。如图20所示,所述屏幕录制方法包括以下步骤:
S1:获取用户输入的用于启动屏幕录制的开始指令。
在用户需要启动屏幕录制功能时,可以输入开始指令。开始指令作为一种控制指令可以通过控制装置100输入。例如,开始指令可以由用户通过按下控制装置100上的“录屏”键输入;或者,用户利用控制装置100上的“上、下、左、右”键,控制选中UI界面上的“录屏”控件,并通过“确认/OK”键确定启动屏幕录制程序。在一些实施例中,开始指令也可以通过其他方式完成输入。例如,用户可以通过显示设备200内置的智能语音系统输入开始指令,即在启动智能语音系统后,通过输入语音“开始录屏”等输入开始指令。又例如,对于支持触控操作的显示设备200,用户可以通过预设手势调出屏幕录制控制菜单,再从控制菜单上点击“开始录屏”选项,从而输入开始指令。在一些实施例中,开始指令还可以通过预设的控制程序完成输入。用户可以在显示设备200中内置自动开始程序。在自动开始程序中,可以设定屏幕录制功能的开始时间,或者设定屏幕录制功能的触发条件。在到达设定的开始时间或者满足设定触发条件时,控制程序可以自动生成开始指令,以便启动屏幕录制。例如,用户可以预先设定自动开始程序为:在凌晨0:30-2:30的时间段内,对体育频道的播出界面进行录制。因此,在到达设定开始时间0:30时,自动生成开始指令并触发启动屏幕录制功能。又例如,用户可以预先设定自动开始程序为:对体育频道播出的欧洲足球冠军联赛转播画面进行录制。因此,显示设备200可以实时监测体育频道播出的节目内容,当节目内容为欧洲足球冠军联赛时,自动生成开始指令并触发启动屏幕录制功能。
S2:响应于所述开始指令,检测视频数据的类型。
在获取开始指令后,显示设备200的控制器250可以控制显示设备200启动屏幕录制功能。而在启动屏幕录制功能前,控制器250还可以对当前视频数据类型进行检测,从而根据不同的视频数据类型采取不同的屏幕录制方式。其中,所述视频数据类型包括标准信号视频或非标准信号视频。标准信号视频是指能够通过视频数据转录的方式完成视频录制的一种显示画面类型,例如,显示设备200在播放电视直播、IPTV、本地资源播放等视频 画面时,确定当前视频数据类型为标准信号视频。通常,显示设备200可以直接获得标准信号视频的视频数据。非标准信号视频是指标准信号视频以外的其他类型的视频显示画面,通常无法通过视频数据转录的方式完成视频录制。例如,web页面画面、多媒体平台画面以及应用程序(app)中的画面等。在一些实施例中,作为非标准信号视频的显示画面通常没有视频数据,或者视频数据较难被显示设备200获得,因此可以通过获取显示画面来确定视频数据类型。
S3:如果所述视频数据为标准信号视频,复制解码前的视频数据,以生成录屏文件。
在检测到当前视频数据类型后,控制器250可以针对检测到的视频数据类型采取相应的屏幕录制方式。如果当前显示的视频数据类型是标准信号视频,则可以直接复制解码前的视频数据,从而生成录屏文件,减轻控制器250的负荷。例如,当用户通过数字电视信号观看直播内容时,控制器250可以检测到当前视频数据类型为标准信号视频,因此可以采用录制TS的方式,即在视频数据进入解码器来解码之前,便将视频数据进行保存,从而不需要重复进行解码和再编码,减轻控制器250的负荷。
S4:如果所述视频数据类型为非标准信号视频,截取当前视频显示画面,以生成录屏文件。
当检测到当前视频数据的类型为非标准信号视频时,控制器250可以启动画面截取程序,对当前视频显示画面进行连续的逐帧截取,从而获得多张视频显示画面图像。控制器250再将多张视频显示画面图像进行组合,形成视频流数据,最后通过执行混合编码等处理,将形成的视频流数据转化成录屏文件。例如,当用户想要对当前操作界面进行屏幕录制时,由于无法获取到当前视频显示画面对应的视频数据,确定当前视频数据类型为非标准信号视频。此时,控制器250控制启动截屏程序,对当前视频显示画面的内容进行逐帧截取,从而形成具有时序关系的多帧图像,以便生成录屏文件。
在一些实施例中所提供的屏幕录制方法在需要录制屏幕时,先判断当前视频数据的类型,从而在视频数据为标准信号视频时,直接通过复制解码前的视频数据生成录屏文件;而在视频数据类型为非标准信号视频时,通过截取当前显示画面的方式,逐帧获取视频画面,以生成录屏文件。所述屏幕录制方法可实现根据不同的视频数据类型,采用不同的屏幕录制方式,适应全部显示画面,而且能够降低屏幕录制时的控制器负荷。在屏幕录制过程中,对于部分显示画面可以仅录制画面内容,例如在对UI界面进行录制时,由于没有相关声音信息,因此可以仅录制视频内容。而对于部分显示画面,则需要对视频画面进行录制的同时,还需要对声音进行录制,以获得带有音频信号的录屏文件。例如,在对电影、电视剧画面进行录制时,需要同时录制视频画面和音频画面。
<非标准信号视频的录屏>
在一些实施例中,如果所述视频数据类型为非标准信号视频,所述屏幕录制方法还包括以下步骤:
S41:获取音频数据;
S42:将所述音频数据与截取的当前显示画面混合编码,以生成录屏文件。
为了实现对音频数据的录制,可以在截取当前显示画面的同时,对音频数据进行获取。音频数据可以通过对音频信号的转化存储获得,也可以通过显示设备200内置的音频输入装置对声音进行录制。获取音频数据后,控制器250可以将获取的音频数据与截取的当前显示画面对应的视频流进行混合编码。经过混合编码后,可以使录屏文件的视频部分和音 频部分保持同步,并且将视频数据和音频数据封装在同一个文件中,以便同时调用。在后续播放录屏文件时,可以通过解码形成视频轨信号和音频轨信号,实现对视频和音频的同步播放。由于检测为非标准信号视频的显示画面中可以包括多种类型的显示内容,例如可以同时包括播放画面、UI界面以及操作动画等,因此显示设备200输入的声音同样由多种声音来源组成。例如,播放画面对应的节目声音、UI界面的提示音以及操作动画的配合音等等。相应的,为了获取音频数据,如图21所示,获取音频数据的步骤还包括:
S411:提取多个音源对应的音频信号;
S412:将所述音频信号输入音频混合器;
S413:在所述音频混合器后端获取混合后的所述音频数据。
为了能够对音频进行录制,在当前视频数据类型为非标准信号视频时,控制器250可以提取显示画面中每种显示画面对应的音频信号,作为多个音源进行播放。其中,所述音源包括系统音源、视频音源以及输入音源。系统音源即UI界面对应的提示音;视频音源即播放的视频画面对应的节目声音;输入音源即通过显示设备200的音频输入装置输入的声音。在提取到多个音源对应的音频信号后,控制器250可以将提取的音频信号输入到音频混合器中。音频混合器可以对输入的多个音源信号进行混合,从而输出音频数据,输入的音频数据一方面可以通过显示设备200的音频输入装置,如扬声器,进行播放,形成声音;另一方面可以被控制器250获得,从而实现对音频数据的录制。
在一些实施例中,控制器250可以从音频混合器的后端获取混合后的音频数据,从而使屏幕录制过程所生成的录屏文件中,不仅包括具体节目中的声音信号,还包括系统提示音、输入音等其他声音信号,实现更完善的屏幕录制功能。同理,对于视频数据类型为标准信号视频的显示画面,也可以对音频数据进行录制。由于作为标准信号视频的显示画面多为具体的视频播放画面,控制器250在获取视频数据的同时也能够获取音频数据。因此,可以直接对播放视频对应音频数据进行复制即可获得录制的音频数据。
有效帧数据:
在一些实施例中,当检测出当前视频数据类型为非标准信号视频时,由于需要对当前显示画面进行逐帧截取,以形成由多个所截取图像构成的视频流。因此,为了使截取后的图像能够形成流畅的视频画面,如果所述画面类型为非标准信号视频,所述屏幕录制方法还包括以下步骤:
S43:获取有效帧数据;
S44:根据所述有效帧数据,在OSD层逐帧截取显示画面。
为了实现对当前视频显示画面进行图像截取,在截取当前视频显示画面前可以先获取有效帧数据,其中,所述有效帧数据为预设最小采样频率。有效帧数据可以在操作系统的控制程序中预先设定,设定的具体数值可以根据显示设备200的硬件配置水平进行设置。例如,为了形成视频动态效果,有效帧数据可以设置为标准动画帧数,即每秒24帧。获取有效帧数据后,控制器250可以按照有效帧数据对应的采样频率在显示画面中进行截取。例如,当预设有效帧数据为每秒24帧时,控制器250可以通过执行画面截取程序在显示画面的OSD层每秒进行24次画面截取,从而每秒获得24张画面图像。其中,OSD(On Screen Display)层即显示设备200所能够呈现画面的最顶层。在OSD层可以包括能够直接在显示器275上进行显示的字符、图形和图像等内容。通过对OSD层画面的截取,可以截取到与显示器275所显示内容相同的图像,从而实现对所有显示画面的录制功能。
通过设置最小的有效帧数据,能够保证录制视频的流畅度。显然,在实际应用中,为了获得更好的视频播放效果,所生成的录屏文件对应的帧率可以设置为更高,相应的截取视频显示画面的频率也相应提高。即在硬件条件允许的情况下,可以将截取过程的采样频率设置为大于所述有效帧数据。例如,实际的视频显示画面截取频率可以为每秒60帧,从而生成60Hz帧率的录屏数据。还可以根据控制器250的运行负荷,自动调整截取画面时的采样频率。显然,当控制器250的处理负荷较大时,则采用较小的采样频率;当控制器250的处理负荷较小时,则采用较大的采样频率。并且,可以随着处理负荷的变化对每次进行屏幕录制的采样频率进行调整,从而在不影响播放过程的前提下,获得更流畅的录屏视频。
在一些实施例中,如图22所示,根据所述有效帧数据,在OSD层逐帧截取显示画面的步骤还包括:
S441:检测所述控制器的使用率;
S442:如果所述使用率小于或等于预设判断阈值,按照所述显示器的刷新频率在OSD层逐帧截取显示画面;
S443:如果所述使用率大于预设判断阈值,按照所述有效帧数据对应的采样频率,在OSD层逐帧截取显示画面。
在截取显示画面前,可以先对控制器250的CPU使用率进行检测,并针对检测获得的CPU使用率数值进行判断。如果使用率小于或等于预设判断阈值,则确定当前控制器250的处理负荷较轻,因此可以采用较高的采样频率,即可以按照显示器275的刷新频率在OSD层逐帧截取显示画面。如果使用率大于预设判断阈值,则确定当前控制器250的处理负荷较重,因此可以采用较低的采样频率,即按照有效帧数据对应的采样频率,在OSD层逐帧截取显示画面。例如,预设判断阈值为50%,当通过检测确定当前控制器250的使用率为5%时,即使用率小于或等于预设判断阈值,因此可以按照显示器275的刷新频率60Hz在OSD层逐帧截取显示画面,以获得帧率为60Hz的录屏文件。当通过检测到当前控制器250的使用率为56%时,确定使用率大于预设判断阈值,则按照有效帧数据对应的采样频率24Hz,在OSD层逐帧截取显示画面,以获得帧率为24Hz的录屏文件。在一些实施例中,对采样频率的调整还可以参考控制器250使用率以外的其他硬件负荷情况进行综合调整。例如,可用内存空间、存储器260剩余空间、CPU主频等。这些负荷参数之间可以根据预设的加权算法确定一个评分值,并按照评分值与相应的判断阈值之间的大小关系确定截取频率。
通过设置最小有效帧数据,保证录制视频的流畅度。同时,通过对控制器250处理负荷的检测,可以实现在硬件条件允许的情况下,生成帧率更高的录屏文件,进一步提升屏幕录制视频的质量。
<标准信号视频的录屏>
在一些例中,如果所述视频数据类型为标准信号视频,显示设备200可以通过直接复制解码前的视频数据,从而生成录屏文件。为了生成录屏文件,如图23所示,所述屏幕录制方法还包括:
S31:获取解复用后标准信号数据;
S32:注册数据获取调用任务,以及使用所述数据获取调用任务将所述标准信号数据添加至录屏数据包;
S33:在所述录屏数据包添加完整后,为所述录屏数据包添加包头,以生成录屏文件。
在一些实施例中,传递至显示设备200的数字电视信号,经过解复用后,可以获得标准信号数据,所述标准信号数据包括视频数据和音频数据。控制器250可以获取解复用后获得的所有视频数据、音频数据以及其他相关数据,例如字幕文档等附加数据(subtitle)。同时,在操作系统中注册数据获取调用任务,并使用数据获取调用任务将标准信号数据逐渐添加至录屏数据包,以收集获取的标准信号数据。在录屏数据包添加完整后,为录屏数据包添加包头,即作为录屏文件的文件名,从而生成录屏文件。
窗口类型:
在一些实施例中,可以针对不同视频数据类型可以实施不同的屏幕录制方法,如图24所示,控制器250被进一步配置为执行以下程序步骤:
S21:遍历所述显示器当前显示画面中包括的窗口类型;
S22:如果当前视频显示画面仅包括数字信号播放窗口,确定所述视频数据类型为标准信号视频;
S23:如果当前视频显示画面包括页面窗口、多媒体窗口和应用窗口中的一种或多种,确定所述视频数据类型为非标准信号视频。
在一些实施例中,在获取开始指令后,控制器250可以通过执行屏幕录制程序对当前视频显示的画面进行检测,遍历当前视频显示画面中包括的窗口类型。通常,显示器275显示画面中可以包括多个窗口,例如,具体的播放窗口、页面窗口、多媒体窗口以及任一应用窗口等。如果当前视频显示画面仅包括数字信号对应的播放窗口,例如用户使用电视直播功能进行DTV(Digital Television)播放,则确定视频数据类型为标准信号视频。因此,对于这种类型的当前视频显示画面,可以采用录制TS流的方式,在进入解码器来解码前,直接复制解复用后的DTV信号数据,并对复制的DTV信号数据进行保存,即可完成屏幕录制。如果当前视频显示画面包括页面窗口、多媒体窗口和应用窗口中的一种或多种,例如当用户使用app、多媒体、网络资源进行视频播放,以及对具体的UI界面也需要进行录制时,则确定画面类型为非标准信号视频。对于非标准信号视频,可以采用截屏的录制方式获取视频数据,同时从混合器后端获取视频数据,进行录制。
在一些实施例中,对于当前视频显示画面,其中可以包括单一的窗口,也可以包括多个窗口。例如,在当前视频显示画面中可以包括一个正在运行的app窗口,也可以同时包括UI界面对应的窗口内容,在检测当前显示画面的显示类型时,可以通过遍历的方式对视频显示画面中所包含的窗口类型进行逐一检测。当检测到当前视频显示画面中包括页面窗口、多媒体窗口或应用窗口时,即可以确定当前视频数据类型为非标准信号视频。即:如果当前视频显示画面包括页面窗口、多媒体窗口和应用窗口中的一种或多种,以及包括所述数字信号播放窗口,确定视频数据类型为非标准信号视频。例如,当显示画面既存在DTV播放窗口,又存在app/多媒体/网络资源播放窗口时,确定当前视频数据类型为非标准信号视频,因此可以同样采用截屏的录制方式,对整个屏幕上显示的画面内容进行录制。同理,为了能够在录制的画面中包括所有窗口中的内容,可以在OSD层进行画面录制,而视频数据同样从混合器后端进行获取。显然,通过对当视频数据类型的检测,确定用户的屏幕录制意图,从而采用不同的屏幕录制方式,实现既能对所有类型的显示画面进行录制,而且能够在录制标准信号视频的显示画面时,直接复制视频数据,避免二次编码,降低控制器250的处理负荷。
由于屏幕录制过程是一个持续一定时间的处理过程,因此在录屏文件会随着录制时间的延长而逐渐增大,直至完成录制后,将生成的录屏文件发送至存储器260,以实现对录屏文件的存储。因此,在一些实施例中,为了存储录屏文件,所述屏幕录制方法还包括以下步骤:
S5:获取用户输入的用于关闭屏幕录制的停止指令;
S6:响应于所述停止指令,将所述录屏文件发送至所述存储器,以通过所述存储器存储所述录屏文件。
停止指令同样可以通过不同的交互方式实现输入。例如,用户可以在屏幕录制过程中通过按下控制装置100上的“退出/返回”键,输入停止指令,以退出屏幕录制程序。用户还可以通过智能语音系统输入语音“退出录屏”等,输入停止指令。在获取停止指令后,控制器250可以响应于该停止指令,一方面停止录制视频数据,另一方面可以执行录屏文件生成过程相关的应用程序,将录制的视频数据进行转化或其他处理,以生成录屏文件。最后,将生成的录屏文件发送至存储器260,以将录屏文件存储在存储器260中。在一些实施例中,停止指令也可以通过控制程序自动完成输入。例如,在到达预设录屏时间段的结束时间,或者指定录制的节目播送完成后,自动输入关闭指令。而根据显示设备200硬件配置,还可以在存储器260的剩余存储空间小于或等于设置的阈值时,自动生成停止指令,以使屏幕录制过程所获得的视频数据能够存储在存储器260中。
为了方便解释,已经结合具体的实施方式进行了上述说明。但是,上述在一些实施例中讨论不是意图穷尽或者将实施方式限定到上述公开的具体形式。根据上述的教导,可以得到多种修改和变形。上述实施方式的选择和描述是为了更好的解释原理以及实际的应用,从而使得本领域技术人员更好的使用实施方式以及适于具体使用考虑的各种不同的变形的实施方式。
