技术领域
本发明实施例涉及视频播放技术领域，尤其涉及一种视频播放方法、播放器及电子装置。
背景技术
随着科学技术的发展，信息传播越来越快，多媒体技术发展日益更新，视频成为信息传播的重要途径，越来越多的用户选择观看视频来获取各种信息。
通常，我们通过超文本传输协议(HyperText Transfer Protocol，HTTP)观看网络视频。所述视频文件的规范格式如图1所示，即视频文件的原始数据moov box中的音频数据及视频数据以分段数据格式存储，这样能保证视频文件的播放流畅。
发明人在实现本发明的过程中发现，然而，在实际播放过程中，还可能会遇到一些由于视频文件本身的不规范导致的播放问题。如图2所示，该视频格式文件中，视频数据和音频数据完全独立分开存放于视频文件中的原始数据moov box中，在实时传输视频文件的过程中，服务器只能单独先传输视频数据或者音频数据，播放器端也只能先读取到视频数据或者音频数据。造成用户在观看视频时会出现，只有图像没有声音，或只有声音没有图像的现象。
发明内容
本发明实施例要解决的技术问题在于，提出一种视频播放方法，以解决播放过程中由于视频文件本身的不规范导致的声音与图片不同步的问题。
本发明实施例另一个要解决的技术问题在于，提出一种视频播放器，以解决播放过程中由于视频文件本身的不规范导致的声音与图片不同步的问题。
本发明实施例又一个要解决的技术问题在于，提出一种电子装置，以解决播 放过程中由于视频文件本身的不规范导致的声音与图片不同步的问题。
为解决上述技术问题，本发明实施例首先提供一种视频播放方法，包括：
S1：向服务器发出下载视频文件的请求；
S2：读取视频文件的元数据头信息并解析所述元数据头信息以获取第一段视频数据的起始位移及数据块大小、第一段音频数据的起始位移及数据块大小；
S3：开启主线程和次线程，所述主线程及次线程分别向服务器发出下载第一段视频数据和第一段音频数据的请求；
S4：接收所述服务器依据所述下载第一段视频数据和第一段音频数据的请求返回的第一段视频数据和第一段音频数据以进行同步播放；及
S5：重复执行S2-S4步骤读取元数据头信息及发送下载下一段视频数据及音频数据的请求并依次下载并播放下一段视频数据及音频数据直到接收到停止下载视频文件的指令或所述视频文件已下载完毕。
另一方面，本发明实施例还提供了一种视频播放器，包括：
请求模块，用于向服务器发出下载视频文件的请求；
播放模块，用于读取视频文件的元数据头信息并解析所述元数据头信息以获取第一段视频数据的起始位移及数据块大小、第一段音频数据的起始位移及数据块大小；开启主线程和次线程，所述主线程及次线程分别向服务器发出下载第一段视频数据和第一段音频数据的请求；接收所述服务器依据所述下载第一段视频数据和第一段音频数据的请求返回的第一段视频数据和第一段音频数据以进行同步播放；重复读取元数据头信息及发送下载下一段视频数据及音频数据的请求并依次下载并播放下一段视频数据及音频数据直到接收到停止下载视频文件的指令或所述视频文件已下载完毕。
又一方面，本发明实施例还提供了一种电子装置，包括如上所述的视频播放器。
又一方面，本发明实施例还提供一种计算机存储介质，其中，该计算机存储介质可存储有程序，该程序执行时可实现本发明实施例提供的一种视频播放方法的全部步骤。
本发明具有如下有益效果：本发明实施例中提供的视频播放方法、装置及电 子装置，通过开启双线程进行分段式下载视频数据及音频数据，进行同步播放并自动进行下一段视频数据及音频数据的下载及播放，从而避免了在视频播放过程中由于视频文件格式不规范导致的声音和图片不同步的问题，从而提升了用户的使用体验。

为了加快下载速度，本发明实施例开启主线程及次线程两个线程，并且主线程及次线程同时向服务器分别发出下载第一段视频数据及第一段音频数据的请求。
进一步的，所述主线程向服务器发出的下载第一段视频数据的请求包括视第一段视频数据的起始位移和数据块大小。
所述次线程向服务器发出的下载第一段音频数据的请求包括第一段音频数据的起始位移和数据块大小。
S4：接收所述服务器依据所述下载第一段视频数据和第一段音频数据的请求返回的第一段视频数据和第一段音频数据以进行同步播放。
具体的，所述服务器接收到下载第一段视频数据和第一段音频数据的请求后，分别向主线程和次线程返回第一段视频数据及第一段音频数据，所述主线程和次线程分别将第一段视频数据及第一段音频数据传送给视频播放器以进行同 步播放。
S5：重复执行S2-S4步骤依次下载并播放下一段视频数据及音频数据直到接收到停止下载视频文件的指令或所述视频文件已下载完毕。
具体的，当第一段视频数据及第一段音频数据传送入视频播放器进行播放时，当前主线程及次线程释放出来了。本实施例的方法重复执行S2-S4步骤开始读取视频文件的元数据头信息以获取第二段视频数据的起始位移及数据块大小、第二段音频数据的起始位移及数据块大小；接着向服务器分别发出下载第二段视频数据及第二段音频数据的请示；并接收所述服务器依据所述下载第二段视频数据和第二段音频数据的请求返回的第二段视频数据和第二段音频数据以进行同步播放。
优选的，为了使所述视频文件的下载及播放流畅，在播放第二段视频数据及第二段音频数据时又重复执行S2-S4步骤以实现第三段视频数据及音频数据的下载及播放，如此反复，直到接收到停止下载视频文件的指令或所述视频文件已下载完毕。
本发明实施例的技术方案，通过向服务器发出下载视频文件的请求；读取视频文件的元数据头信息并解析所述元数据头信息以获取第一段视频数据的起始位移及数据块大小、第一段音频数据的起始位移及数据块大小；开启主线程和次线程，所述主线程及次线程分别向服务器发出下载第一段视频数据和第一段音频数据的请求；接收所述服务器依据所述下载第一段视频数据和第一段音频数据的请求返回的第一段视频数据和第一段音频数据以进行同步播放；依次下载并播放下一段视频数据及音频数据直到接收到停止下载视频文件的指令或所述视频文件已下载完毕。由于通过开启双线程进行分段式下载视频数据及音频数据，进行同步播放并自动进行下一段视频数据及音频数据的下载及播放，从而避免了在视频播放过程中由于视频文件格式不规范导致的声音和图片不同步的问题，从而提升了用户的使用体验。
