我正在开发一个窗口电话7应用程序,并播放录像。 我愿获得视频文件(MP4)的正确部分,并对声音作一些改进。 我认为,作为AAC框架在MP4中可以节省下来。 (权利?) 我怎么能从手工艺品4的档案中提取声音?
由于这是一个视频文件,它可能是巨大的文件。 因此,向云层上载和加工不会有好选择。 由于该工作计划7的申请,我无法使用无遗的 d: 在纯C#中是否有办法? 任何开放源工具/工具?
感谢!
MP4是一种集装箱格式,现实地说,正确的部分总是自动取款机。 它可以是MP3,也可以是任何其他不同的录音形式。 你们也许想的是M4A,我认为这要求非洲排雷中心或拉美加勒比国家联盟。
关于音频提取问题,应当能够使用公正管理的密码从MP4中提取录音。 须在MP4格式上阅读(,例如:也值得阅读),然后通过查找自己的录音地点和复制件。 即便如此,你也不得不承认,当你自己没有获得任何支持的录音形式时。
可能已经建立了一个网上图书馆,能够做到这一点,但我不知道。 这可能不是很受欢迎的,因为管理法肯定不是从中处理这一问题的最佳途径,但考虑到这是Windows Telephone,正如你指出的那样,这是你的唯一途径。
亲爱!
