本发明的说明书和权利要求书中的术语“第一”、“第二”等是用于区别不同对象,而非用于描述特定顺序。此外,术语“包括”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或模块的过程、方法、***、产品或设备没有限定于已列出的步骤或模块,而是可选地还包括没有列出的步骤或模块,或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或模块。
可选地,本发明实施例的技术方案可具体应用于手机(如Android手机、iOS手机等)、平板电脑、移动互联网设备(mobile internet devices,简称MID)、个人数字助理(personal digital assistant,简称PDA)、摄像机、照相机等具有录像功能的设备中。
进一步可选地,该拍摄设备中可设置传感器(sensor)以用于采集图像,并可根据拍摄帧率以及输出图像的帧率来实现慢动作、正常速度、缩时摄影效果的切换等等。其中,假设拍摄时在单位时间内如1秒内获取图像帧数为M张(即帧率为Mfps),而播放时按照每单位时间N张进行播放(即帧率为Nfps),若M大于N,即为慢速模式,则可得到一个慢动作效果;若M小于N,即为快速模式,则可得到一个快动作效果;若M等于N,即为正常模式,则可得到一个正常播放效果。其中,M和N均大于0。例如,假设拍摄设备在高帧率(如120p)拍摄,输出30p的视频,即为4x慢动作摄影,如果1s拍摄1张照片,30s输出1秒钟30p的视频,即为30x缩时摄影。
本发明实施例公开了一种视频录制方法、装置及拍摄设备,能够按照用户需求的录制速率录制视频,从而提升了视频的录制效率及灵活性。以下分别详细说明。
请参见图1,图1是本发明实施例提供的一种视频录制方法的流程示意图。 具体地,如图1所示,本发明实施例的所述视频录制方法可以包括以下步骤:
101、获取拍摄设备在播放视频图像时的播放速率。
102、获取基于用户选择指令确定出的录制速率参数。
具体地,在进行视频录制时,可根据用户需求来确定该视频录制的录制速率参数。比如,可提供多个速率按键(比如在拍摄设备本身或与该拍摄设备连接的云台上设置该速率按键)以供用户选择录制速率参数,或者通过输出一个包括多种录制速率的交互界面以供用户选择录制速率参数,或者通过输出一个窗口以使用户直接输入该录制速率参数等等,对于该录制速率参数的确定方式,本发明实施例不做限定。其中,该录制速率参数可以是具体的速率值,如15fps、30fps、60fps、120fps等等;或者,该录制速率参数还可以是用于指示放慢录制速率或加快录制速率的速率变化值,如加快3倍(+3x)、放慢4倍(-4x)等等。
103、基于所述播放速率和所述录制速率参数对所述视频图像进行录制。
具体地,在确定出播放视频时的播放速率以及需求的录制速率参数之后,即可基于该播放速率和该录制速率参数对视频图像进行录制,比如可基于该播放速率和该录制速率参数计算写入速率,以基于该写入速率写入视频数据,从而完成视频录制。其中,该播放速率可以与该拍摄设备的拍摄速率相匹配,从而可实现一边拍摄视频一边录制,拍摄完成即可录制完成,视频录制的灵活性及效率较高。
在本发明实施例中,可通过获取拍摄设备在播放视频图像时的播放速率以及基于用户选择指令确定出的录制速率参数,以基于该播放速率和该录制速率参数对视频图像进行录制,使得能够按照用户需求的录制速率录制视频,从而提升了视频的录制效率及灵活性。
进一步地,请参见图2,图2是本发明实施例提供的另一种视频录制方法的流程示意图。具体地,如图2所示,本发明实施例的所述视频录制方法可以包括以下步骤:
201、获取拍摄设备在播放视频图像时的播放速率。
202、获取基于用户选择指令确定出的录制速率参数。
可选地,所述获取基于用户选择指令确定出的录制速率参数,可以具体为: 获取所述拍摄设备的设备参数信息;基于所述设备参数信息确定出所述拍摄设备所支持的至少一组录制速率参数;显示包括所述至少一组录制速率参数的交互界面;接收用户针对所述至少一组录制速率参数输入的选择指令,该选择指令种可指示有确定出的录制速率参数。从而能够基于该选择指令确定用户需求的录制速率参数。
具体地,由于不同拍摄设备支持的帧率范围可能不同,则可通过获取拍摄设备的设备参数信息,如设备型号等,来确定出该拍摄设备能够支持的帧率,以确定出录制的最慢速度或最快速率是正常速度的倍数,从而能够基于拍摄设备支持的帧率来进行视频录制。可选地,在确定出拍摄设备能够支持的帧率之后,可以输出该支持帧率对应的录制速率以供用户选择,以使用户从中选择出一个速率作为录制速率进行视频录制。在其他可选的实施例中,用户还可通过点击预设按键输入该录制速率参数,如通过点击设置于拍摄设备或者设置于与该拍摄设备连接的云台上的速率按键输入该录制速率参数。
203、基于所述播放速率和所述录制速率参数,计算所述视频图像对应的视频数据的写入速率。
204、按照所述写入速率对所述视频图像进行录制。
可选地,所述基于所述播放速率和所述录制速率参数,计算所述视频图像对应的视频数据的写入速率,可以具体为:当所述录制速率参数指示的录制模式确定为快速模式时,确定所述录制速率参数与所述播放速率的第一比值;基于所述播放速率、所述快速模式和所述第一比值计算写入速率,并将计算得到的所述写入速率作为所述视频图像对应的视频数据的写入速率。具体地,当检测到用户选择的录制速率参数对应为快速模式,则可获取该录制速率参数与该播放速率的倍数,即第一比值,并可基于该第一比值对录制的视频进行快动作处理并写入文件进行存储。例如,假设获取的播放速率为30fps,检测到用户点击设置的速率按键“+3x”,则可确定该“+3x”对应的录制模式为快速模式,该第一比值为3,并可计算得到该写入速率为120fps,则可按照该录制速率参数对播放速率加快3倍的写入速率写入视频数据。
可选地,所述基于所述播放速率和所述录制速率参数,计算所述视频图像对应的视频数据的写入速率,可以具体为:当所述录制速率参数指示的录制模 式确定为慢速模式时,确定所述播放速率与所述录制速率参数的第二比值;基于所述播放速率、所述慢速模式和所述第二比值计算写入速率,并将计算得到的所述写入速率作为所述视频图像对应的视频数据的写入速率。具体地,可通过获取拍摄设备所支持的帧率范围和正常的播放速率,确定出支持的最大帧率是该播放速率的倍数,以进一步确定出慢速的范围。当检测到用户选择的录制速率对应为慢速模式,则可获取该播放速率与录制速率参数的倍数,即第二比值,并基于该第二比值对录制的视频进行慢动作处理并写入文件进行存储。例如,假设获取的播放速率为60fps,检测到用户点击设置的速率按键“-2x”,则可确定该“-2x”对应的录制模式为慢速模式,该第二比值为2,并可计算得到该写入速率为30fps,则可按照该录制速率参数对播放速率放慢2倍的写入速率写入视频数据。
可选地,该录制参数还可以是具体的速率值,则还可将用户可对拍摄设备进行操作输入的录制速率参数指示的速率值作为该写入速率。
205、接收基于用户操作输入的速率更改指令。
206、响应所述速率更改指令,暂停对所述视频图像的录制,并获取所述速率更改指令对应的新的录制速率参数。
207、基于所述播放速率和所述新的录制速率参数对所述视频图像进行录制。
在录制过程中,还可检测是否接收到用于指示更改录制速率的速率更改指令,以便于在确认接收到用户更改指令时进行录制速率更改,从而实现对录制速率的灵活调整。其中,该速率更改指令中携带后更改后的录制速率信息,即新的录制速率参数。例如,可预先在拍摄设备上增加指示录制速率的速率按键,如在拍摄设备的手持云台上增加加速/减速(+/-)的速率按键,通过点击该速率按键,可以切换sensor的工作模式为120p、30p、1p或更多。用户可以通过操作拍摄设备的手持云台上的按键,即可更改制定的视频录制速率,从而实现录像过程中智能调速、快慢速的结合。
进一步可选地,在一些实施例中,还可在检测到该录制速率参数输入或者拍摄设备暂停播放视频图像时,停止对所述视频图像进行录制。进一步地,可在获取到新的写入速率时,按照新的写入速率继续录制。
进一步可选地,在一些实施例中,还可基于所述视频图像进行对象跟踪。其中,该对象跟踪(tracking)所使用的线程、该视频图像播放所使用的线程与该视频图像录制所使用的线程可相互独立。其中,tracking是指在图像里选择一个特定的目标(如人、动物等),所述目标移动时,视频录制装置可以跟随所述目标移动,以使所述目标始终处于所述视频录制装置拍摄的图像或视频之内,tracking用的是可以是与录制的视频图像相同的图像,可以是不同的图像。tracking利用图像可以为拍摄获取的原始图,以保证跟踪的效率;而录制的视频图像可以是原始图,也可以是被处理过的图像。
具体地,如图3所示,在本发明实施例中,视频流的独立线程负责处理视频流数据,并可将视频流复制成多份数据。其中,一份可通过中央处理器(central processing unit,简称CPU)进行帧率调节并交给视频录制线程做录制视频操作;一份可交给视频显示线程通过图像处理器(graphics processing unit,简称GPU)做视频显示;一份可交给tracking线程通过GPU处理。从而可通过多线程下的多路资源调度,实现同时显示视频、录制视频以及tracking,并通过CPU或GPU的合理的资源分配处理,确保了录制速率的快速灵活切换,以及视频快速合成。
举例来说,当基于用户需求对已存储的视频图像或者当前正在拍摄的视频图像进行录制时,用户可进行录制速率的选择并点击开始录制,从而触发根据该选择的录制速率参数和该录制的视频图像对应的播放速率进行视频录制。具体地,可在本地的文件夹的指定目录新建一个文件,同时新建一个写入线程进行线程轮循,在需要录制的视频处于非暂停状态下时,可根据用户设置的目标录制速度是按照慢速模式还是快速模式进行录制视频的视频数据写入,通过修改视频回调数据的时间来写入数据到文件中。进一步地,在视频录制过程中,若用户需要修改录制速率,在接收到用户输入的速率修改指令,比如用户点击了另外一个录制速率触发的速率录制指令时,可先暂停录制,并获得的用户设置的最新录制速率,即新的录制速率参数。检测该新的录制速率参数为慢速模式或快速模式,并基于新的录制速率参数去设置视频回调帧率,即确定出新的写入速率。进一步地,可将暂停模式关闭,以保证写入线程继续写入数据。当用户点击停止录制时,或者视频播放完成时,写入完成,即可关闭线程。此时 完成录制。
在本发明实施例中,可通过一个独立写入线程的控制以及写入视频数据速率的更改来保证录制和其他操作同步进行,从而较优地实现多路操作,如可一边进行视频显示,一边调速录像,并同时支持tracking,使得能够实现一次得到快慢相间的视频,这就减少了生成视频的等待时间。同时,通过对GPU和CPU的合理资源分配,使得多路数据操作仍能同时流畅地进行,并能够通过修改回调的视频数据的时间进行写入即修改录制视频的写入速率,来防止丢帧现象的发生,从而有效提升了视频录制的效率、灵活性和可靠性。
