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.
你需要做AV媒体转码，还是只是换个容器？标准（非流媒体）MOV 容器将/应该与 MP4 容器兼容（检查来自 iOS 的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。这确实假设容器中的媒体受 MP4 容器支持。仅供参考，MP4 的 ISO 规范基于 Quicktime 文件格式。此外，如果您在设备上录制媒体，则可以选择 MP4 作为媒体的容器。
