推荐答案

您需要进行AV媒体转码，还是只需更换容器？标准（非流媒体）MOV容器将/应该与MP4容器兼容（从iOS检查一些测试文件显示它们是相同的）。因此，您可以将文件重命名为MP4。这确实假设MP4容器支持容器中的介质。仅供参考，MP4的ISO规范基于Quicktime文件格式。此外，如果您要在设备上录制媒体，则可以选择MP4作为媒体的容器。

Do you need to do AV media transcoding, or just change the container? A standard (not streaming) MOV container will/should be compatible with a MP4 container (inspection of a few test files from iOS show they are identical). So it is possible that you could just rename the file to MP4. This does assume the media in the container is supported by the MP4 container. FYI, The ISO spec for MP4 is based on the Quicktime file format. Also, if you are recording the media on the device then you can select MP4 as the container for the media.
