继续参考图2，其示出了根据本申请的视频合并播放方法的一个实施例的流程200。该视频合并播放方法包括以下步骤：Continue to refer to FIG. 2 , which shows a
步骤201，采用边下载边缓存的方式缓存视频列表，以及为视频列表中的视频的未下载部分预留缓存空间。In
在本实施例中，当用户打开短视频应用时，短视频应用的客户端(例如图1所示的设备101)可以向短视频应用的服务端(例如图1所示的设备102)发送视频列表请求。服务端可以向客户端推送包括但不限于用户喜爱的或用户好友发布的视频组成的视频列表。然后，客户端可以采用边下载边缓存的方式从服务端下载并缓存视频列表。In this embodiment, when the user opens the short video application, the client of the short video application (such as the
通常，客户端缓存的视频列表中的视频不是完整的视频，仅包含视频的一部分。而客户端会为视频列表中的视频的未下载部分预留缓存空间，以便于给视频的后续下载使用。这样，就能尽快达到起播状态。其中，缓存空间可以用于缓存视频。为了避免客户端缓存浪费，可以基于视频的大小来确定缓存空间的大小。当然，在客户端缓存充足的情况下，也可以确定视频列表中的最大视频的大小，为每个视频都预留不小于最大视频的大小的缓存空间。Usually, the videos in the video list cached by the client are not complete videos, but only part of the video. And the client will reserve cache space for the undownloaded part of the video in the video list, so as to be used for subsequent downloading of the video. In this way, the starting state can be reached as soon as possible. Among them, the cache space can be used to cache video. In order to avoid wasting the cache on the client side, the size of the cache space can be determined based on the size of the video. Certainly, in the case that the client cache is sufficient, the size of the largest video in the video list may also be determined, and a cache space not smaller than the size of the largest video is reserved for each video.
在一些实施例中，短视频应用的服务端中存储的视频的格式多样，包括但不限于MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面4)、FLV(Flash Video，流媒体格式)等等。如果直接从服务端下载视频列表，客户端的播放器不仅需要支持播放多种格式的视频，还需要在不同格式的视频中进行切换，增加视频切换耗时。因此，服务端可以对视频列表中的视频进行统一格式转换。例如，经过转码器转换成统一格式的视频。而具体转换成的格式需要与客户端的播放器匹配。其中，客户端的播放器支持的格式就是与客户端的播放器匹配的格式。例如，客户端的播放器支持MP4，则可以统一转换成MP4。又例如，客户端的播放器同时支持MP4和FLV，则既可以统一转换成MP4，也可以统一转换成FLV。In some embodiments, the format of the video stored in the server of the short video application is various, including but not limited to MP4 (Moving Picture Experts Group Audio Layer IV, moving picture expert compression standard audio level 4), FLV (Flash Video, stream media format), etc. If the video list is directly downloaded from the server, the client player not only needs to support playing videos in multiple formats, but also needs to switch between videos in different formats, which increases the time-consuming of video switching. Therefore, the server can perform uniform format conversion on the videos in the video list. For example, a video converted into a unified format by a transcoder. The specific converted format needs to match the client's player. Wherein, the format supported by the player of the client is the format matching the player of the client. For example, if the player of the client supports MP4, it can be converted into MP4 uniformly. For another example, if the player of the client side supports both MP4 and FLV, it can be converted into MP4 or FLV in a unified manner.
步骤202，获取视频列表中的视频对应的控制指令。
在本实施例中，视频列表中的每个视频都可以插入控制指令。客户端可以获取视频列表中的每个视频对应的控制指令。In this embodiment, control instructions can be inserted into each video in the video list. The client can acquire the control instruction corresponding to each video in the video list.
通常，控制指令可以指明视频的播放逻辑，如播放完毕之后是重播还是播放下一条等。控制指令可以包括但不限于以下至少一种类型：播放指令、用户控制指令等等。其中，指令服务器可以根据默认播放逻辑生成播放指令。播放指令可以在视频播放结束时触发，包括但不限于以下至少一项：重播、播放下一条、播放上一条等等。指令控制器可以基于用户操作(如seek操作)生成用户控制指令。用户控制指令可以即时触发，包括但不限于以下至少一项：快进、快退、慢进、慢退等等。Usually, the control instruction can indicate the playing logic of the video, such as whether to replay or play the next video after the video is played. The control instruction may include but not limited to at least one of the following types: play instruction, user control instruction and so on. Wherein, the instruction server may generate the playback instruction according to the default playback logic. The playback instruction can be triggered when the video playback ends, including but not limited to at least one of the following: replay, play the next one, play the previous one, and so on. The instruction controller can generate user control instructions based on user operations (such as seek operations). The user control instruction can be triggered immediately, including but not limited to at least one of the following: fast forward, fast rewind, slow forward, slow rewind and so on.
步骤203，在视频列表中的视频后插入对应的控制指令。
在本实施例中，对于视频列表中的每个视频对应的控制指令，客户端可以将其插入在对应的视频之后。In this embodiment, for the control instruction corresponding to each video in the video list, the client may insert it after the corresponding video.
步骤204，按顺序播放视频列表，以及响应于触发控制指令，基于控制指令控制对应视频的播放状态。
在本实施例中，客户端的视频管理器可以将缓存的视频列表中的视频按顺序传递给客户端的播放器。这样，播放器可以按顺序播放视频列表，以使视频在客户端的用户界面显示。当触发到控制指令时，基于控制指令控制对应视频的播放状态。其中，对于播放指令，在播放到播放指令时，控制对应视频的播放状态，如重播、播放下一条、播放上一条等等。对于用户控制指令，在当前视频插入用户控制指令时，控制对应视频的播放状态，如快进、快退、拖动播放进度等等。In this embodiment, the video manager of the client may deliver the videos in the cached video list to the player of the client in order. In this way, the player can play the list of videos sequentially so that the videos are displayed on the user interface of the client. When the control instruction is triggered, the playing state of the corresponding video is controlled based on the control instruction. Wherein, for the play command, when the play command is played, the play status of the corresponding video is controlled, such as replay, next play, previous play, and so on. For the user control command, when the current video inserts the user control command, control the playback state of the corresponding video, such as fast forward, fast rewind, drag the playback progress, and so on.
在一些实施例中，控制指令除了可以控制对应视频的播放状态，还可以控制后续视频的播放状态。因此，若对应视频播放结束，基于控制指令继续控制后续视频的播放状态。例如，若用户控制当前视频倍速播放，在当前视频播放结束之后，继续倍速播放后续视频。In some embodiments, in addition to controlling the playing state of the corresponding video, the control instruction can also control the playing state of the subsequent video. Therefore, if the playing of the corresponding video ends, the playing state of the subsequent video is continued to be controlled based on the control instruction. For example, if the user controls the double-speed playback of the current video, the subsequent video will continue to be played at double-speed after the current video is played.
本申请实施例提供的视频合并播放方法，首先采用边下载边缓存的方式缓存视频列表，以及为视频列表中的视频的未下载部分预留缓存空间；之后获取视频列表中的视频对应的控制指令；然后在视频列表中的视频后插入对应的控制指令；最后按顺序播放视频列表，以及响应于触发控制指令，基于控制指令控制对应视频的播放状态。通过适当的内存管理和指令管理来提升视频切换效率，解决视频卡顿问题。In the combined video playback method provided by the embodiment of the present application, the video list is cached first by caching while downloading, and the cache space is reserved for the undownloaded part of the video in the video list; then the control command corresponding to the video in the video list is acquired ; Then insert corresponding control instructions after the videos in the video list; finally play the video list in order, and in response to triggering the control instructions, control the playback status of the corresponding videos based on the control instructions. Through proper memory management and command management, video switching efficiency can be improved, and the video freeze problem can be solved.
进一步参考图3，其示出了是根据本申请的视频合并播放方法的又一个实施例的流程300。该视频合并播放方法包括以下步骤：Further referring to FIG. 3 , it shows a
步骤301，采用边下载边缓存的方式缓存视频列表，以及为视频列表中的视频的未下载部分预留缓存空间。
在本实施例中，步骤301具体操作已在图2所示的实施例中步骤201进行了详细的介绍，在此不再赘述。In this embodiment, the specific operation of
步骤302，在用户界面显示当前播放的视频。
在本实施例中，在播放器播放视频列表中的当前视频时，在用户界面上可以显示当前播放的视频。In this embodiment, when the player plays the current video in the video list, the currently played video can be displayed on the user interface.
步骤303，响应于检测到用户在用户界面上的用户操作，将用户操作的数据发送给指令控制器。
在本实施例中，用户可以在用户界面上对当前视频进行用户操作。客户端可以采集用户操作的数据，并发送给指令控制器。In this embodiment, the user can perform user operations on the current video on the user interface. The client can collect user operation data and send it to the command controller.
这里，采用控制指令和码流结合，避免用户采用上下翻页才能切换视频。用户可以随意定义用户操作与用户控制指令对应。当执行用户操作时，会将对应的用户控制指令插入到视频中，由播放器进行解析。比如，可以定义点击操作对应视频切换指令。用户点击用户界面产生数据，传递到指令控制器生成视频切换指令。视频切换指令直接插入到当前视频末尾。播放器播放到指令时，立即执行视频切换指令，直接加载跳转到下一条视频头开始播放。界面完全不用切换，节省用户界面操作。Here, the combination of control commands and code streams is used to prevent users from turning pages up and down to switch videos. Users can freely define the correspondence between user operations and user control instructions. When a user operation is performed, the corresponding user control instruction will be inserted into the video, which will be parsed by the player. For example, it may be defined that a click operation corresponds to a video switching instruction. The user clicks on the user interface to generate data, which is transmitted to the command controller to generate a video switching command. Video switching instructions are inserted directly at the end of the current video. When the player reaches the command, it immediately executes the video switching command, directly loads and jumps to the next video head to start playing. There is no need to switch the interface at all, saving user interface operations.
步骤304，接收指令控制器基于用户操作的数据生成的用户控制指令。
在本实施例中，指令控制器可以基于用户操作的数据生成用户控制指令，并发送给客户端。In this embodiment, the instruction controller may generate a user control instruction based on user operation data and send it to the client.
步骤305，在视频列表中的视频后插入对应的控制指令。
步骤306，按顺序播放视频列表。
在本实施例中，步骤305-306具体操作已在图2所示的实施例中步骤203-204进行了详细的介绍，在此不再赘述。In this embodiment, the specific operations of steps 305-306 have been introduced in detail in steps 203-204 in the embodiment shown in FIG. 2 , and will not be repeated here.
步骤307，用户操作是否发生在一个视频内。
在本实施例中，在视频播放过程中，客户端可以确定检测到的用户操作是否发生在一个视频内。若发生在一个视频内，执行步骤308，若发生在至少两个视频间，执行步骤309。In this embodiment, during video playback, the client may determine whether the detected user operation occurs within a video. If it occurs within one video, perform
步骤308，基于用户控制指令控制一个视频的播放状态。
在本实施例中，若用户操作发生在一个视频内，客户端可以基于用户控制指令控制这一个视频的播放状态。例如，若对一个视频常规快进，则仅控制这一个视频常规快进即可。In this embodiment, if the user operation occurs in a video, the client can control the playback state of the video based on the user control instruction. For example, if a video is normally fast-forwarded, only the normal fast-forward of this video can be controlled.
步骤309，基于用户控制指令控制至少两个视频中的一个视频的播放状态。Step 309: Control the playing state of one of the at least two videos based on the user control instruction.
在本实施例中，若用户操作发生在至少两个视频间，客户端可以基于用户控制指令控制至少两个视频中的一个视频的播放状态。In this embodiment, if the user operation occurs between at least two videos, the client may control the playback state of one of the at least two videos based on the user control instruction.
步骤310，若一个视频播放结束，跳转播放至少两个视频中的下一个视频，以及基于用户控制指令继续控制至少两个视频中的下一个视频的播放状态。
在本实施例中，若一个视频播放结束，客户端可以跳转播放至少两个视频中的下一个视频，以及基于用户控制指令继续控制至少两个视频中的下一个视频的播放状态。In this embodiment, if one video is played, the client can jump to play the next video of the at least two videos, and continue to control the playback state of the next video of the at least two videos based on user control instructions.
通常，对于用户操作发生在至少两个视频间，普通的用户操作通常控制到第一个视频的末尾就结束了。而本申请实施例补充了跳转等控制指令，当控制到第一个视频的末尾时会触发控制指令，跳转到下一个视频继续控制。Usually, for user operations that occur between at least two videos, common user operations usually end at the end of the first video. However, in the embodiment of the present application, control commands such as jump are supplemented. When the control reaches the end of the first video, the control command will be triggered to jump to the next video to continue control.
从图3中可以看出，与图2对应的实施例相比，本实施例中的视频合并播放方法的流程300突出了用户操作控制步骤。由此，本实施例描述的方案用户可以基于需求进行用户操作，生成相应的用户控制指令，以控制视频的播放状态。并且，对于发生在至少两个视频间的用户操作，补充了跳转等控制指令，当控制到第一个视频的末尾时会触发控制指令，跳转到下一个视频继续控制。It can be seen from FIG. 3 that, compared with the embodiment corresponding to FIG. 2 , the
为了便于理解，图4提供了可以实现本申请的视频合并播放方法的应用场景图。如图4所示，当用户打开客户端上的短视频应用时，会向短视频应用的视频服务器发送视频列表请求。视频服务器中存储有视频1、视频2和视频3组成的视频列表。视频服务器将视频1、视频2和视频3进行视频转码为客户端的播放器支持的格式。客户端采用边下载边缓存的方式从视频服务器下载视频列表，并缓存到视频缓存中。视频缓存中的视频不是完整的视频，仅包含视频的一部分。而视频缓存会为视频列表中的视频的未下载部分预留缓存空间，以便于给视频的后续下载使用。视频列表中的视频对应的控制指令来自于指令控制器。其中，控制指令包括播放指令和用户控制指令两种类型。播放指令由指令服务器生成，经由指令控制器，插入视频列表中的视频后。客户端的视频管理器将视频缓存中的视频列表传递给播放器进行播放时，在用户界面(UI)上显示当前播放的视频。用户在用户界面上对当前视频进行用户操作。用户操作的数据会发送给指令控制器。指令控制器基于用户操作的数据生成用户控制指令，插入视频列表中的视频后。视频管理器将缓存的视频列表中的视频按顺序传递给播放器。播放器按顺序播放视频列表，视频在用户界面显示。当触发到控制指令时，基于控制指令控制对应视频的播放状态。For ease of understanding, FIG. 4 provides an application scenario diagram that can implement the combined video playing method of the present application. As shown in Figure 4, when the user opens the short video application on the client, a video list request will be sent to the video server of the short video application. A video list consisting of video 1, video 2 and video 3 is stored in the video server. The video server transcodes video 1, video 2 and video 3 into a format supported by the player of the client. The client downloads the video list from the video server by caching while downloading, and caches it in the video cache. The video in the video cache is not a complete video, it only contains a part of the video. The video cache will reserve cache space for the undownloaded part of the video in the video list, so that it can be used for subsequent downloading of the video. The control commands corresponding to the videos in the video list come from the command controller. Wherein, the control instruction includes two types of play instruction and user control instruction. The play command is generated by the command server and inserted after the video in the video list via the command controller. When the video manager of the client sends the video list in the video buffer to the player for playing, the currently playing video is displayed on the user interface (UI). The user performs user operations on the current video on the user interface. The data operated by the user will be sent to the command controller. The command controller generates a user control command based on the data operated by the user, and inserts it behind the video in the video list. The video manager delivers the videos in the cached video list to the player in order. The player plays a list of videos in order, and the videos are displayed in the user interface. When the control instruction is triggered, the playing state of the corresponding video is controlled based on the control instruction.
其中，图5示出了视频缓存中的视频列表的示意图。视频1包括视频1已下载数据和视频1未下载预留，其后插入控制指令。同理，视频2包括视频2已下载数据和视频2未下载预留，其后插入控制指令。视频2包括视频2已下载数据和视频2未下载预留，其后插入控制指令。Wherein, FIG. 5 shows a schematic diagram of a video list in the video cache. Video 1 includes the downloaded data of Video 1 and the undownloaded reservation of Video 1, and then inserts control instructions. Similarly, the video 2 includes the downloaded data of the video 2 and the undownloaded reservation of the video 2, and then inserts the control instruction. Video 2 includes the downloaded data of Video 2 and the reserved video 2 undownloaded data, and then inserts control instructions.
其中，图5示出了视频间的指令控制的示意图。若用户操作发生在视频1、视频2和视频3之间。当跳转到下一个视频时，进行指令解析，从视频1、视频2和视频3的地址中查找视频起始地址，组装指令，得到跳转地址，播放器根据跳转地址加载视频继续进行播放状态控制。Wherein, FIG. 5 shows a schematic diagram of instruction control between videos. If the user operation occurs between video 1, video 2 and video 3. When jumping to the next video, perform instruction analysis, find the video start address from the addresses of video 1, video 2 and video 3, assemble the instructions, and get the jump address, and the player loads the video according to the jump address to continue playing state control.
