Description
本发明涉及终端技术领域，具体而言，涉及一种多媒体文件处理方法、一种多媒体文件处理装置和一种终端。
目前，无论是单系统终端还是多系统终端，都是由其当前操作系统处理多媒体文件。比如，单系统手机都是通过其自身的音视频编解码器对支持格式的音视频进行编码或解码，对不支持的格式的音视频则无法进行编码或解码，并且，终端在处理音视频文件时无法直接对音视频文件提供保护，这就容易造成用户敏感信息的泄露，因此，现有的终端一般通过对音视频文件进行二次加密的方式来保护其中的敏感信息。然而，对音视频文件进行二次加密不仅费时费力，还会花费较高的成本，降低了用户体验。
因此，需要一种新的技术方案，可以有效地保护需要处理的多媒体文件中的敏感信息，并降低保护成本。
