目前，终端在录制完成的音视频后，并没有对该音视频进行检测其音频或视频的完整性，从而在将音视频上传到云端进行分享时，无法保证上传所录制的音视频是正常的，可能会存在上传到云端的音视频有图像而没有声音，或者有声音而没有图像，需要用户重新录制与上传，非常麻烦。以智能电视为例，智能电视的随着android系统的出现，K歌在TV上的应用越来越流行，用户可以将自己唱的歌曲上传到云端与朋友分享。假设小李在家通过智能电视唱了一首歌，并进行录制后上传到云端与朋友分享，但是上传到云端的KTV视频没有声音的，而智能电视系统并没有自动的提醒当前录制的K歌曲丢失了音频，小李需要重新录制与上传。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1所示，示出了本发明一种终端检测录制音视频丢失的方法第一实施例。该实施例的终端检测录制音视频丢失的方法包括：
步骤S10、获取完成录制的音视频对应的时间总长度及有效数字音频数据；
本实施例中，终端的类型类型可根据具体情况进行设置，例如，该终端可包括手机、智能电视、iPad等。录制的音视频的内容可以根据实际需要进行设置，例如，可以是录制歌曲、演讲、访谈等。以下将以智能电视录制歌曲为例进行详细说明。
首先用户打开智能电视的K歌应用，并通过智能电视预置的按键开始对歌曲进行录制，智能电视系统接收到录制歌曲的命令后，执行录制操作。在完成歌曲录制后，将所录制的歌曲保存在存储区中。假设用户已经录制完成刘德华的“爱你一万年”和张学友的“心如刀绞”这两首歌曲。智能电视系统将获取用户录制的歌曲名称，并根据用户录制的时间先后顺序，依次将歌曲名称与对应的音频文件和视频文件分别保存到存储区11。需要说明的是，在完成歌曲录制后，也可以是分别设置每首歌曲的唯一标识，根据该唯一标识将歌曲对应的音频文件和视频文件分别保存到存储区11，后续可通过唯一标识获取每首歌曲对应的参数信息。可以理解的是，用户也可以根据需要录制多首歌曲，并不限定本发明。
然后智能电视系统获取存储区11中每首歌曲的时间总长度，将得到的时间总长度传送到存储区22中进行存储。例如，得到“爱你一万年”的时间总长度为300秒，“心如刀绞”的时间总长度为400秒，根据歌曲的名称分别对应保存到存储区22中。
得到歌曲的时间总长度后，为了将时间总长度明显不对的歌曲过滤掉，再判断音频是否丢失，进一步地，上述步骤S1可包括：当时间总长度大于预设时间值时，根据完成录制的音视频所在的存储区，将非零数字的个数作为有效数字音频数据。
具体地，智能电视系统判断存储区22中每首歌曲的总时间长度是否大于预设时间值。该预设时间值可根据具体情况而灵活设置，例如，可设置为歌曲的总时间长度的二分之一或三分之一等；也可设置为固定值，由于正常歌曲一般都有200秒左右，一般歌曲的二分之一时间是100秒，因此该固定值可设置为100秒。
当歌曲的总时间长度小于或等于预设时间值时，说明录制过程出现断层，系统不做后续的处理。当得到歌曲的总时间长度大于预设时间值时，则获取完成录制的歌曲所在存储区11中的非零数字的个数作为有效数字音频数据，并将得到的有效数字音频数据保存在存储区33中。
需要说明的是，有效数字音频可定义为在某个时间点存在的数字音频。假设在得到的音频数据中，以大于1的数字标识该数字音频有效，以“0”标识该数字音频无效，则通过计算歌曲中大于1的数字音频的个数即可得到有效数字音频数据。当然，有效数字音频数据的计算方法也可以根据具体情况而灵活设置，并不限定本发明。
以下进行举例说明，针对上述“爱你一万年”及“心如刀绞”这两首歌，智能电视系统根据歌曲的时间总长度将预设时间值设置为100秒，“爱你一万年”的时间总长度为300秒，“心如刀绞”的时间总长度为400秒，这两首歌的时间总长度都大于100秒，则将分别获取这两首歌曲的有效数字音频数据，例如，“爱你一万年”的有效数字音频数据为350个，“心如刀绞”的有效数字音频数据为380个，并分别存储在存储区33中。
步骤S20、根据时间总长度与有效数字音频数据判断音频是否丢失；
在上述得到时间总长度及有效数字音频数据后，根据时间总长度及有效数字音频数据判断音频是否丢失，进一步地，上述步骤S20可包括：
当获取到的有效数字音频数据大于预设个数时，将所述有效数字音频数据与所述时间总长度进行比较；
若所述有效数字音频数据大于所述时间总长度，则音频未丢失。
具体地，分别判断每首歌曲的有效数字音频数据是否大于预设个数时，该预设个数的设置与数模转换模块1秒内能够处理的数据个数有关，可根据具体情况而灵活设置。例如，可设置为100个或者1000个等。当有效数字音频数据小于或等于预设个数时，说明音频文件丢失，将设定音频文件丢失的标志保存在存储区44中。例如，用“0”表示音频文件丢失，用“1”表示音频文件未丢失，且不进行后续视频检测的处理。以便在完成所有歌曲的检测后，根据该标志显示有关音频丢失的信息，从而提醒用户。当有效数字音频数据大于预设个数时，将有效数字音频数据与时间总长度进行比较，即进行逻辑判断。
当有效数字音频数据小于或等于时间总长度时，说明音频文件丢失，用“0”标识音频文件丢失状态并保存在存储区55中，且不进行后续视频检测的处理。当有效数字音频数据大于时间总长度时，说明音频文件未丢失，用“1”标识音频文件未丢失状态并保存在存储区55中，可进一步对视频文件是否丢失进行检测。可以理解的是，音频文件是否丢失的状态可根据具体情况而灵活设置，并不限定本发明。
由于视频和音频有一一对应的关系，例如，1秒看到60帧率视频，可听到1秒有效音频，因此本实施例中利用有效数字音频数据进行判断音频是否丢失，当音频丢失时，视频也会被判断丢失，即音频丢失后将不再对视频进行判断。
针对上述“爱你一万年”及“心如刀绞”这两首歌，将预设个数设置为100个。上述存储在存储区33中“爱你一万年”和“心如刀绞”的有效数字音频数据分别为为350个及380个，都大于100个，则此时将这两首歌的音频文件丢失的标志设定为“1”并保存在存储区44中。
由于上述“爱你一万年”的有效数字音频数据为350及时间总长度为300，则将有效数字音频数据与时间总长度作差比较：350-300=50，即有效数字音频数据大于时间总长度，该首歌的音频文件未丢失，可继续检测其视频文件是否丢失。“心如刀绞”的有效数字音频数据为380及时间总长度为400，则380-400=-20，即有效数字音频数据小于时间总长度，该首歌的音频文件丢失，停止对其检测。分别用“1”和“0”标识“爱你一万年”和“心如刀绞”对应的音频文件是否丢失的情况保存在存储区55中。
步骤S30、当音频丢失时，在终端界面显示音频丢失信息以提醒用户。
在上述完成对所录制的音视频中的音频文件进行检测后，为了直观地提醒用户是否需要重新录制，系统将根据音频丢失状态存储区44或存储区55，中的信息，将在智能电视的荧幕上显示所录制的音视频中，音频的录制情况。即在智能电视的屏幕将显示歌曲名称及对应“丢失音频数据”的信息，以提醒用户所录制的歌曲存在音频丢失。或者通过语音对歌曲音频的录制情况进行播报，以提醒用户。
以上述录制的“爱你一万年”和“心如刀绞”这两首歌为例进行说明，经过检测，由于录制的“爱你一万年”音频不丢失，而录制的“心如刀绞”音频丢失，因此在智能电视的荧屏上显示：“爱你一万年”音频完整，“心如刀绞”音频丢失的信息。可以理解的是，该信息可通过列表的形式进行显示，还可通过其他方式进行显示，并不限定本发明。
本发明实施例中智能电视在完成音视频的录制后，通过时间总长度及有效数字音频数据判断音频是否丢失，并显示音频及视频的录制情况。实现了对智能电视所录制的音视频进行检测，并在智能电视录制音视频后自动提醒音频视频是否丢失，保证上传所录制的音视频是正常的。智能电视录制音视频后自动提醒音频视频是否丢失，提高了用户体验。
进一步地，如图2所示，基于上述终端检测录制音视频丢失的方法第一实施例，提出了本发明终端检测录制音视频丢失的方法第二实施例，本实施例中，上述步骤S10之后可包括：
步骤S20、根据所述时间总长度与有效数字音频的个数判断音频是否丢失；若是，则执行上述步骤S30；若否，则依次执行步骤S40、步骤S50及步骤S60。
步骤S40、获取视频图像总数及有效视频图像数据；
当上述歌曲的音频未丢失时，对视频进行检测，具体地，获取时间总长度与第一视频帧率之间的乘积作为视频图像总数，并获取有效数字音频数据与第二视频帧率之间的乘积作为有效视频图像数据。该第一视频帧率为参考的标准帧，该第二视频帧率为从视频文件所保存的存储区11读取得到的动态帧率，可根据具体情况而灵活设置。例如，第二视频帧率可包括1秒60帧、1秒30帧、1秒24帧、1秒50帧、1秒120帧等。
上述歌曲“爱你一万年”中，时间总长度为300秒，有效数字音频数据为350个，假设第一视频帧率为1秒60帧，则得到的视频图像总数为300×60=18000帧。假设第二视频帧率为1秒100帧，有效视频图像数据为350×100=35000帧。
步骤S50、根据视频图像总数及有效视频图像数据判断视频是否丢失；
步骤S60、当有效视频图像数据小于或等于视频图像总数，则视频丢失，并在终端界面显示视频丢失信息以提醒用户。
将上述得到的视频图像总数与有效视频图像数据进行比较，若有效视频图像数据小于或等于视频图像总数，则说明视频丢失，并以“0”作为标识保存在存储区66中。当有效视频图像数据大于视频图像总数，则视频未丢失。并以“1”作为标识保存在存储区66中。可以理解的是，该标识可根据具体情况而灵活设置，并不限定本发明。智能电视系统自动的提醒目前歌曲的录制情况，而且不需要人为的干预和控制，保证用户上传所录制的音视频没有丢失音频或者视频。
上述歌曲“爱你一万年”中，得到的视频图像总数为18000帧，有效视频图像数据为35000帧，则将有效视频图像数据与视频图像总数进行作差比较：35000-18000=17000帧，即有效视频图像数据大于视频图像总数，说明该歌曲的视频未丢失，并以“1”作为标识保存在存储区66中。
需要说明的是，本实施例中，为了减少对数据的处理，优选地先对音频进行检测再对视频进行检测，当然也可以先对视频进行检测再对音频进行检测，并不限定本发明。
当视频丢失时，在终端界面显示视频丢失信息以提醒用户。具体地，根据视频丢失状态存储区66中的信息，将在智能电视的荧幕上显示所录制的音视频中视频的录制情况。例如，在上述对录制的“爱你一万年”进行视频检测后，由于录制的“爱你一万年”音频及视频都不丢失，因此在智能电视的荧屏上显示：“爱你一万年”音频文件及视频文件完整，可以理解的是，该信息可通过列表的形式进行显示，也可通过其他方式进行显示，或者是通过语音进行播报，以便直观地提醒用户。
对应地，如图3所示，提出本发明一种终端检测录制音视频丢失的装置第一实施例。该实施例的终端检测录制音视频丢失的装置包括：
第一获取模块100，用于获取完成录制的音视频对应的时间总长度及有效数字音频数据；
本实施例中，终端的类型类型可根据具体情况进行设置，例如，该终端可包括手机、智能电视、iPad等。录制的音视频的内容可以根据实际需要进行设置，例如，可以是录制歌曲、演讲、访谈等。以下将以智能电视录制歌曲为例进行详细说明。
首先用户打开智能电视的K歌应用，并通过智能电视预置的按键开始对歌曲进行录制，智能电视系统接收到录制歌曲的命令后，执行录制操作。在完成歌曲录制后，将所录制的歌曲保存在存储区中。假设用户已经录制完成刘德华的“爱你一万年”和张学友的“心如刀绞”这两首歌曲。智能电视系统将获取用户录制的歌曲名称，并根据用户录制的时间先后顺序，依次将歌曲名称与对应的音频文件和视频文件分别保存到存储区11。需要说明的是，在完成歌曲录制后，也可以是分别设置每首歌曲的唯一标识，根据该唯一标识将歌曲对应的音频文件和视频文件分别保存到存储区11，后续可通过唯一标识获取每首歌曲对应的参数信息。可以理解的是，用户也可以根据需要录制多首歌曲，并不限定本发明。
然后智能电视系统调用第一获取模块100获取存储区11中每首歌曲的时间总长度，将得到的时间总长度传送到存储区22中进行存储。例如，得到“爱你一万年”的时间总长度为300秒，“心如刀绞”的时间总长度为400秒，根据歌曲的名称分别对应保存到存储区22中。
得到每首歌曲的时间总长度后，为了将时间总长度明显不对的歌曲过滤掉，再判断音频是否丢失，进一步地，第一获取模块100还用于，当时间总长度大于预设时间值时，根据完成录制的音视频所在的存储区，将非零数字的个数作为有效数字音频数据。
具体地，智能电视系统调用第一获取模块100判断存储区22中每首歌曲的总时间长度是否大于预设时间值。该预设时间值可根据具体情况而灵活设置，例如，可设置为歌曲的总时间长度的二分之一或三分之一等；也可设置为固定值，由于正常歌曲一般都有200秒左右，一般歌曲的二分之一时间是100秒，因此该固定值可设置为100秒。
当歌曲的总时间长度小于或等于预设时间值时，说明录制过程出现断层，系统不做后续的处理。当得到歌曲的总时间长度大于预设时间值时，则由第一获取模块100获取完成录制的歌曲所在存储区11中的非零数字的个数作为有效数字音频数据，并将得到的有效数字音频数据保存在存储区33中。
需要说明的是，有效数字音频可定义为在某个时间点存在的数字音频。假设在得到的音频数据中，以大于1的数字标识该数字音频有效，以“0”标识该数字音频无效，则第一获取模块100通过计算歌曲中大于1的数字音频的个数即可得到有效数字音频数据。当然，有效数字音频数据的计算方法也可以根据具体情况而灵活设置，并不限定本发明。
以下进行举例说明，针对上述“爱你一万年”及“心如刀绞”这两首歌，智能电视系统根据歌曲的时间总长度将预设时间值设置为100秒，“爱你一万年”的时间总长度为300秒，“心如刀绞”的时间总长度为400秒，这两首歌的时间总长度都大于100秒，则将分别获取这两首歌曲的有效数字音频数据，例如，“爱你一万年”的有效数字音频数据为350个，“心如刀绞”的有效数字音频数据为380个，并分别存储在存储区33中。
第一判断模块200，用于根据时间总长度与有效数字音频数据判断音频是否丢失；
在上述第一获取模块100得到时间总长度及有效数字音频数据后，由第一判断模块200根据时间总长度及有效数字音频数据判断音频是否丢失，进一步地，第一判断模块200还用于，当获取到的有效数字音频数据大于预设个数时，将所述有效数字音频数据与所述时间总长度进行比较；若所述有效数字音频数据大于所述时间总长度，则音频未丢失。
具体地，第一判断模块200分别判断每首歌曲的有效数字音频数据是否大于预设个数时，该预设个数的设置与数模转换模块1秒内能够处理的数据个数有关，可根据具体情况而灵活设置。例如，可设置为100个或者1000个等。当有效数字音频数据小于或等于预设个数时，说明音频文件丢失，将设定音频文件丢失的标志保存在存储区44中。例如，用“0”表示音频文件丢失，用“1”表示音频文件未丢失，且不进行后续视频检测的处理。以便在完成所有歌曲的检测后，根据该标志显示有关音频丢失的信息，从而提醒用户。当有效数字音频数据大于预设个数时，第一判断模块200将有效数字音频数据与时间总长度进行比较，即进行逻辑判断。
当有效数字音频数据小于或等于时间总长度时，说明音频文件丢失，用“0”标识音频文件丢失状态并保存在存储区55中，且不进行后续视频检测的处理。当有效数字音频数据大于时间总长度时，说明音频文件未丢失，用“1”标识音频文件未丢失状态并保存在存储区55中，可进一步对视频文件是否丢失进行检测。可以理解的是，音频文件是否丢失的状态可根据具体情况而灵活设置，并不限定本发明。
由于视频和音频有一一对应的关系，例如，1秒看到60帧率视频，可听到1秒有效音频，因此本实施例中利用有效数字音频数据进行判断音频是否丢失，当音频丢失时，视频也会被判断丢失，即音频丢失后将不再对视频进行判断。
针对上述“爱你一万年”及“心如刀绞”这两首歌，将预设个数设置为100个。上述存储在存储区33中“爱你一万年”和“心如刀绞”的有效数字音频数据分别为为350个及380个，都大于100个，则此时将这两首歌的音频文件丢失的标志设定为“1”并保存在存储区44中。
由于上述“爱你一万年”的有效数字音频数据为350及时间总长度为300，则将有效数字音频数据与时间总长度作差比较：350-300=50，即有效数字音频数据大于时间总长度，该首歌的音频文件未丢失，可继续检测其视频文件是否丢失。“心如刀绞”的有效数字音频数据为380及时间总长度为400，则380-400=-20，即有效数字音频数据小于时间总长度，该首歌的音频文件丢失，停止对其检测。分别用“1”和“0”标识“爱你一万年”和“心如刀绞”对应的音频文件是否丢失的情况保存在存储区55中。
显示模块300，用于当音频丢失时，在终端界面显示音频丢失信息以提醒用户。
在上述完成对所录制的音视频中的音频文件进行检测后，为了直观地提醒用户是否需要重新录制，系统将根据音频丢失状态存储区44或存储区55，中的信息，由显示模块300将在智能电视的荧幕上显示所录制的音视频中，音频的录制情况。即在智能电视的屏幕将显示歌曲名称及对应“丢失音频数据”的信息，以提醒用户所录制的歌曲存在音频丢失。或者通过语音对歌曲音频的录制情况进行播报，以提醒用户。
