[英]Known issues for playing 3gp videos in the AVPlayer framework?

原文 2017-04-11 23:17:12 7 1 ios/ swift

Are there any known issues with AVPlayer not playing a 3gp file on device? AVPlayer没有在设备上播放3gp文件时有任何已知问题吗？ mp4 files play fine, but playing a 3gp file back from a URL on the device isn't happening. mp4文件播放正常，但没有发生从设备上的URL播放3gp文件。

Thanks! 谢谢！

If it matters I'm on iOS 9 Swift 3. 如果它重要我在iOS 9 Swift 3上。

AVPlayer or AVPlayerViewController can play only 3gp files that have audio and video streams that are supported by Apple. AVPlayer或AVPlayerViewController只能播放3gp文件，这些文件具有Apple支持的音频和视频流。

For example, 3gp file can have AMR audio stream(Adaptive Multi-Rate, a format for speech) - which is not supported since iOS 4.3 例如，3gp文件可以具有AMR音频流（自适应多速率，语音格式） - 自iOS 4.3起不支持
