具体实施方式detailed description

下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

本发明实施例提供了一种视频数据的缓冲方法，如图1所示，所示方法包括：The embodiment of the present invention provides a buffering method of video data, as shown in Figure 1, the shown method includes:

101、在播放视频数据的过程中，将待播放视频数据缓存在预置缓冲长度的视频缓冲区中。101. During the process of playing video data, cache the video data to be played in a video buffer with a preset buffer length.

其中，所述视频缓冲区为视频数据的缓冲区，在视频缓冲区中进行视频数据的缓冲。所述预置缓冲长度可以根据用户的实际需求进行配置，也可以由系统默认配置，本发明实施例不做限定。Wherein, the video buffer is a buffer of video data, and video data is buffered in the video buffer. The preset buffer length can be configured according to the actual needs of the user, or can be configured by default by the system, which is not limited in this embodiment of the present invention.

对于本发明实施例，当需要播放视频数据时，首先将待播放视频数据缓存在预置缓冲长度的视频缓冲区中，再从预置缓冲长度的视频缓冲区中读取视频数据进行播放。For the embodiment of the present invention, when video data needs to be played, the video data to be played is first buffered in a video buffer with a preset buffer length, and then the video data is read from the video buffer with a preset buffer length for playback.

进一步地，在所述将待播放视频数据缓存在预置缓冲长度的视频缓冲区中之前，可以获取当前的网络状态信息，根据当前的网络状态信息获取得到当前网络的下载速度，根据当前网络的下载速度，将所述预置缓冲长度配置为与所述下载速度对应的缓冲长度，不同的下载速度对应不同的预置缓冲长度。Further, before the video data to be played is cached in the video buffer with a preset buffer length, the current network state information can be obtained, and the download speed of the current network can be obtained according to the current network state information, and the download speed of the current network can be obtained according to the current network state information. For the download speed, the preset buffer length is configured as a buffer length corresponding to the download speed, and different download speeds correspond to different preset buffer lengths.

例如，存在3个预置缓冲长度，分别为长度A、长度B、长度C，将属于100KB/s至200KB/s之间的下载速度对应长度A，将属于300KB/s至400KB/s之间的下载速度对应长度B，将属于500KB/s至600KB/s之间的下载速度对应长度C。当网络当前的下载速度为150KB/s时，将预置缓冲长度配置为长度A；当网络当前的下载速度为512KB/s时，将预置缓冲长度配置为长度C。For example, there are 3 preset buffer lengths, namely length A, length B, and length C, which will belong to the corresponding length A of the download speed between 100KB/s and 200KB/s, and will fall between 300KB/s and 400KB/s The download speed corresponding to length B will belong to the download speed between 500KB/s and 600KB/s corresponding to length C. When the current download speed of the network is 150KB/s, configure the preset buffer length as length A; when the current download speed of the network is 512KB/s, configure the preset buffer length as length C.

对于本发明实施例，根据网络的实际情况配置预置缓冲长度，当网速较好时，可以将预置缓冲长度配置得较短一些，以提高直播视频播放的实时性；当网速较差时，可以将预置缓冲长度配置得较长一些，以保证直播视频播放的流畅性。For the embodiment of the present invention, the preset buffer length is configured according to the actual situation of the network. When the network speed is good, the preset buffer length can be configured to be shorter to improve the real-time performance of live video playback; when the network speed is poor , you can configure the preset buffer length to be longer to ensure the smoothness of live video playback.

再进一步地，在所述将待播放视频数据缓存在预置缓冲长度的视频缓冲区中之前，还可以输出提示信息，所述提示信息用于确认是否按照预置缓冲长度进行数据缓冲，当用户根据提示信息确认按照预置缓冲长度进行数据缓冲时，将待播放视频数据缓存在预置缓冲长度的视频缓冲区中；当用户根据提示信息取消按照预置缓冲长度进行数据缓冲时，可以输出预置缓冲长度的修改信息，用于用户修改预置缓冲长度，在预置缓冲长度修改完成之后，再将待播放视频数据缓存在修改后的预置缓冲长度的视频缓冲区中。Still further, before the video data to be played is cached in the video buffer with a preset buffer length, prompt information can also be output, and the prompt information is used to confirm whether to perform data buffering according to the preset buffer length. When the user According to the prompt information, when the data buffering according to the preset buffer length is confirmed, the video data to be played is buffered in the video buffer with the preset buffer length; when the user cancels the data buffering according to the preset buffer length according to the prompt information, the preset buffer length can be output. The modification information of the preset buffer length is used for the user to modify the preset buffer length. After the modification of the preset buffer length is completed, the video data to be played is cached in the modified video buffer of the preset buffer length.

102、按照预置时间间隔检测当前视频数据的播放状态信息是否符合预设条件。102. Detect whether the playing state information of the current video data meets a preset condition according to a preset time interval.

其中，所述播放状态信息可以为视频缓冲区中视频数据量的状态信息，也可以为播放视频数据时的网络状态信息。所述预设条件可以按用户需求进行配置，也可以由系统默认配置，本发明实施例不做限定。所述预置时间间隔可以根据实际需求进行配置，例如，预置时间间隔可以配置为1秒、2秒等。Wherein, the playing state information may be the state information of the amount of video data in the video buffer, or may be the network state information when playing the video data. The preset conditions may be configured according to user requirements, or may be configured by default by the system, which is not limited in this embodiment of the present invention. The preset time interval may be configured according to actual requirements, for example, the preset time interval may be configured as 1 second, 2 seconds, and so on.

例如，当需要检测的播放状态信息为视频缓冲区中视频数据量的状态信息时，预设条件可以配置为视频缓冲区中剩余的视频数据量大于数据量A，当视频数据当前的视频缓冲区中剩余的视频数据量小于或等于数据量A时，即视频缓冲区中的视频数据将要播空，判定当前视频数据的播放状态信息不符合预置条件；当视频数据当前的视频缓冲区中剩余的视频数据量大于数据量A时，判定当前视频数据的播放状态信息符合预置条件。For example, when the playback status information to be detected is the status information of the amount of video data in the video buffer, the preset condition can be configured as the amount of video data remaining in the video buffer is greater than the amount of data A, when the current video buffer of the video data When the amount of remaining video data in the video buffer is less than or equal to the amount of data A, that is, the video data in the video buffer will be aired, and it is determined that the playback status information of the current video data does not meet the preset conditions; when the remaining video data in the current video buffer is When the amount of video data in is greater than the amount of data A, it is determined that the playback state information of the current video data meets the preset condition.

再例如，当前视频数据的播放状态信息可以为播放视频数据时的网络状态信息，预设条件可以配置为视频数据的下载速度小于或等于速度b，即以该区间定义网络处于拥塞状态，当检测出当前视频数据的下载速度大于速度b时，可以确定当前网络处于正常状态，网速较好，判定当前视频数据的播放状态信息不符合预置条件；当检测出当前视频数据的下载速度小于b时，可以确定当前网络处于拥塞状态，网速较差，判定当前视频数据的播放状态信息符合预置条件。For another example, the playback status information of the current video data can be the network status information when the video data is played, and the preset condition can be configured such that the download speed of the video data is less than or equal to the speed b, that is, the interval defines that the network is in a congested state. When the download speed of the current video data is greater than speed b, it can be determined that the current network is in a normal state and the network speed is better, and it is determined that the playback status information of the current video data does not meet the preset conditions; when it is detected that the download speed of the current video data is less than b , it can be determined that the current network is in a congested state and the network speed is poor, and it is determined that the playback status information of the current video data meets the preset conditions.

103、根据检测结果，对视频缓冲区对应的预置缓冲长度进行调整。103. According to the detection result, adjust the preset buffer length corresponding to the video buffer.

例如，预设数据量A用于确定视频数据播放时是否出现卡顿现象，具体地，当检测出视频缓冲区中剩余的视频数据量大于预设数据量A时，确定视频数据播放过程中没有出现卡顿现象，当检测出视频缓冲区中剩余的视频数据量小于或等于预设数据量A时，确定视频数据播放过程中出现了卡顿现象，可以对视频缓冲区对应的预置缓冲长度进行增大，具体可以将新的预置缓冲长度配置为原有预置缓冲长度的两倍，以减少发生直播视频播放卡顿的现象。For example, the preset data amount A is used to determine whether there is a jam phenomenon during video data playback. Specifically, when it is detected that the remaining video data amount in the video buffer is greater than the preset data amount A, it is determined that there is no video data during playback. Caton phenomenon occurs, when it is detected that the amount of video data remaining in the video buffer is less than or equal to the preset data amount A, it is determined that there has been a jam phenomenon during the playback of video data, and the corresponding preset buffer length of the video buffer can be adjusted. To increase, specifically, the new preset buffer length can be configured to be twice the original preset buffer length, so as to reduce the phenomenon of live video playback stuttering.

再例如，预设下载速度B用于确定网络是否处于正常状态，具体地，当检测出当前视频数据的下载速度小于或等于预设下载速度B时，可以确定当前网络处于拥塞状态，网速较差，当检测出当前视频数据的下载速度大于预设下载速度B时，可以确定当前网络处于正常状态，网速较好，可以对视频缓冲区对应的预置缓冲长度进行减小，具体可以将新的预置缓冲长度配置为原有预置缓冲长度的一半，并相应删除部分缓冲数据，以提高直播视频播放的实时性。For another example, the preset download speed B is used to determine whether the network is in a normal state. Specifically, when it is detected that the download speed of the current video data is less than or equal to the preset download speed B, it can be determined that the current network is in a congested state, and the network speed is relatively low. Poor, when it is detected that the download speed of the current video data is greater than the preset download speed B, it can be determined that the current network is in a normal state and the network speed is good, and the preset buffer length corresponding to the video buffer can be reduced. The new preset buffer length is configured as half of the original preset buffer length, and part of the buffer data is deleted accordingly to improve the real-time performance of live video playback.

对于本发明实施例，可以根据播放视频数据时的网络状态信息或者视频缓冲区中视频数据量的状态信息，例如，视频缓冲区中剩余的视频数据量、当前视频数据的下载速度、视频缓冲区中剩余的视频数据量的减少量以及增加量等，调整视频缓冲区对应的预置缓冲长度。可以实现在直播视频流畅播放与滞后播放之间的动态调整，并且可以配置相应的阈值，来保证在调整的过程中，预置缓冲长度不会超过特定范围，进而可以保证调整的准确性。For the embodiment of the present invention, according to the network state information or the state information of the amount of video data in the video buffer when playing video data, for example, the remaining video data amount in the video buffer, the download speed of the current video data, the video buffer Adjust the preset buffer length corresponding to the video buffer. Dynamic adjustment between smooth playback and delayed playback of live video can be realized, and the corresponding threshold can be configured to ensure that the preset buffer length will not exceed a specific range during the adjustment process, thereby ensuring the accuracy of the adjustment.

本发明实施例提供的一种视频数据的缓冲方法，首先在播放视频数据的过程中，将待播放视频数据缓存在预置缓冲长度的视频缓冲区中；然后按照预置时间间隔检测当前视频数据的播放状态信息是否符合预设条件；最后根据检测结果，对所述视频缓冲区对应的所述预置缓冲长度进行调整。与目前通过缓冲固定长度的视频数据的方式相比，本发明在播放视频数据的过程中，通过检测当前视频数据的播放状态信息是否符合预设条件，可以对视频缓冲区对应的预置缓冲长度进行实时调整，进而可以实现在直播视频流畅播放与滞后播放之间的动态调整，在网络较好的情况下，使用较短的缓冲区进行实时播放；在网络较差的情况下，使用较长的缓冲区保证流畅播放，减少了发生直播视频播放卡顿的现象，提升了用户的体验。A video data buffering method provided by an embodiment of the present invention firstly buffers the video data to be played in a video buffer with a preset buffer length in the process of playing video data; then detects the current video data according to a preset time interval Whether the playback state information of the video buffer meets the preset condition; finally, according to the detection result, the preset buffer length corresponding to the video buffer is adjusted. Compared with the current method of buffering fixed-length video data, the present invention can check the preset buffer length corresponding to the video buffer by detecting whether the playback status information of the current video data meets the preset conditions during the process of playing video data. Real-time adjustments can be made to achieve dynamic adjustments between smooth playback and delayed playback of live video. When the network is good, a shorter buffer is used for real-time playback; when the network is poor, a longer buffer is used. The buffer zone ensures smooth playback, reduces the phenomenon of live video playback stuttering, and improves the user experience.

本发明实施例提供了另一种视频数据的缓冲方法，如图2所示，所示方法包括：The embodiment of the present invention provides another video data buffering method, as shown in Figure 2, the shown method includes:

201、在播放视频数据的过程中，将待播放视频数据缓存在预置缓冲长度的视频缓冲区中。201. During the process of playing video data, cache the video data to be played in a video buffer with a preset buffer length.

其中，所述视频缓冲区为视频数据的缓冲区，在视频缓冲区中进行视频数据的缓冲。所述预置缓冲长度可以根据用户的实际需求进行配置，也可以由系统默认配置，本发明实施例不做限定。Wherein, the video buffer is a buffer of video data, and video data is buffered in the video buffer. The preset buffer length can be configured according to the actual needs of the user, or can be configured by default by the system, which is not limited in this embodiment of the present invention.

对于本发明实施例，当需要播放视频数据时，首先将待播放视频数据缓存在预置缓冲长度的视频缓冲区中，再从预置缓冲长度的视频缓冲区中读取视频数据进行播放。For the embodiment of the present invention, when video data needs to be played, the video data to be played is first buffered in a video buffer with a preset buffer length, and then the video data is read from the video buffer with a preset buffer length for playback.

对于本发明实施例，可以根据当前网络的下载速度，配置所述预置缓冲长度。例如，当网络当前的下载速度较差时，为了保证直播视频数据播放的流畅性，可以将预置缓冲长度配置得较长一些；而当网络当前的下载速度较好时，为了保证直播视频数据播放的实时性，可以将预置缓冲长度配置得较短一些。For the embodiment of the present invention, the preset buffer length may be configured according to the download speed of the current network. For example, when the current download speed of the network is poor, in order to ensure the smoothness of live video data playback, the preset buffer length can be configured to be longer; For real-time playback, the preset buffer length can be configured to be shorter.

202a、按照预置时间间隔检测视频缓冲区中剩余的视频数据量是否大于预设数据量。202a. Detect whether the remaining video data volume in the video buffer is greater than the preset data volume at a preset time interval.

其中，所述预置时间间隔可以根据实际需求进行配置，也可以由系统默认进行配置，本发明实施例不做限定，例如，预置时间间隔可以配置为0.5秒、1秒等。Wherein, the preset time interval can be configured according to actual needs, or can be configured by default by the system, which is not limited in the embodiment of the present invention. For example, the preset time interval can be configured as 0.5 second, 1 second, etc.

203a1、若视频缓冲区中剩余的视频数据量大于预设数据量，则将预置缓冲长度减小为与预设数据量对应的缓冲长度。203a1. If the amount of video data remaining in the video buffer is greater than the preset data amount, reduce the preset buffer length to a buffer length corresponding to the preset data amount.

其中，不同预设数据量对应不同的缓冲长度。所述预设数据量可以根据实际需求进行设定。Wherein, different preset data amounts correspond to different buffer lengths. The preset data volume can be set according to actual needs.

203a2、若视频缓冲区中剩余的视频数据量小于预设数据量，则将预置缓冲长度增大为与预设数据量对应的缓冲长度。203a2. If the amount of video data remaining in the video buffer is less than the preset data amount, increase the preset buffer length to a buffer length corresponding to the preset data amount.

例如，存在4个不同的预设数据量，并且按照数据量从大到小的顺序，依次为数据量1、数据量2、数据量3、数据量4，数据量1的数据量最大；与数据量1对应的缓冲长度为长度a，与数据量2对应的缓冲长度为长度b，与数据量3对应的缓冲长度为长度c，与数据量4对应的缓冲长度为长度d，在上述条件下进行视频数据播放，当检测出视频缓冲区中剩余的视频数据量小于或等于数据量1且大于数据量2时，将预置缓冲长度增大为长度a；当检测出视频缓冲区中剩余的视频数据量小于或等于数据量3且大于数据量4时，将预置缓冲长度增大为长度c。For example, there are 4 different preset data volumes, and in descending order of data volumes, they are data volume 1, data volume 2, data volume 3, and data volume 4, and data volume 1 has the largest data volume; and The buffer length corresponding to data volume 1 is length a, the buffer length corresponding to data volume 2 is length b, the buffer length corresponding to data volume 3 is length c, and the buffer length corresponding to data volume 4 is length d. Under the above conditions Play video data under the following conditions, when it is detected that the amount of video data remaining in the video buffer is less than or equal to the amount of data 1 and greater than the amount of data 2, the preset buffer length is increased to length a; when it is detected that the remaining amount of video data in the video buffer When the amount of video data is less than or equal to data amount 3 and greater than data amount 4, the preset buffer length is increased to length c.

需要说明的是，通过检测视频缓冲区中剩余的视频数据量是否大于预设数据量，可以实现在视频流畅播放与滞后时间做出动态的调整，以减少播放视频卡顿现象的发生，以保证视频的实时性播放。It should be noted that by detecting whether the amount of video data remaining in the video buffer is greater than the preset amount of data, dynamic adjustments can be made to smooth video playback and lag time to reduce the occurrence of video freezes and ensure Real-time playback of video.

与步骤202a并列的步骤202b、按照预置时间间隔检测当前视频数据下载速度是否大于预设速度。Step 202b parallel to step 202a is to detect whether the current video data download speed is greater than the preset speed according to a preset time interval.

进一步地，所述步骤202b之前，还可以包括：获取与当前视频数据的播放模式信息对应的预设速度，不同播放模式对应不同的预设速度。所述步骤202b具体可以包括：按照预置时间间隔检测当前视频数据下载速度是否大于与所述播放模式信息对应的预设速度。其中，所述播放模式信息可以包含视频数据播放的分辨率、码率(Bitrate，比特率)等。例如，当视频数据播放的码率较高时，传送的数据较大，对应的预设速度较快，当视频数据播放的码率较低时，传送的数据较小，对应的预设速度较慢。Further, before the step 202b, it may also include: acquiring a preset speed corresponding to the play mode information of the current video data, and different play modes correspond to different preset speeds. The step 202b may specifically include: detecting whether the download speed of the current video data is greater than the preset speed corresponding to the playing mode information at a preset time interval. Wherein, the playing mode information may include resolution, bit rate (Bitrate, bit rate) and the like of video data playing. For example, when the bit rate of video data playback is high, the transmitted data is larger, and the corresponding preset speed is faster; when the bit rate of video data playback is lower, the transmitted data is smaller, and the corresponding preset speed is faster. slow.

进一步地，所述方法还包括：若当前视频数据下载速度小于或等于与所述播放模式信息对应的预设速度，则输出提示信息，所述提示信息用于确认是否切换当前视频数据的播放模式。其中，所述提示信息可以为文本提示信息、图片提示信息、音频提示信息、视频提示信息等。Further, the method further includes: if the download speed of the current video data is less than or equal to the preset speed corresponding to the playback mode information, then output prompt information, the prompt information is used to confirm whether to switch the playback mode of the current video data . Wherein, the prompt information may be text prompt information, picture prompt information, audio prompt information, video prompt information, and the like.

例如，如果判断出当前视频数据的下载速度小于或等于与播放模式信息对应的预设速度，可以通过终端设备的显示屏显示“是否将当前视频数据的分辨率切换为较低的分辨率”的文字提示信息，并且可以通过终端设备的音频输出端输出“是否将当前视频数据的分辨率切换为较低的分辨率”的语音提示信息。For example, if it is judged that the download speed of the current video data is less than or equal to the preset speed corresponding to the playback mode information, the screen of "whether to switch the resolution of the current video data to a lower resolution" can be displayed on the display screen of the terminal device. Text prompt information, and the voice prompt information of "whether to switch the resolution of the current video data to a lower resolution" can be output through the audio output terminal of the terminal device.

需要说明的是，通过按照预置时间间隔检测当前视频数据下载速度是否大于与所述播放模式信息对应的预设速度，若小于或等于所述预设速度，则输出用于是否切换当前视频数据的播放模式的提示信息，可以使得用户根据网络下载速度的实际情况，调整当前视频数据的播放模式，当网络水平较差时，通过降低视频数据的分辨率，可以提高直播视频数据播放的流畅性。It should be noted that, by detecting whether the download speed of the current video data is greater than the preset speed corresponding to the playback mode information according to the preset time interval, if it is less than or equal to the preset speed, the output is used to determine whether to switch the current video data.
