android - iPhone 无法从我的网页（服务器）播放视频

Question

我正在使用NanoHTTPD来自 android 设备的流式传输视频。每个设备都可以播放网页中的视频文件或使用外部媒体播放器，除了iPhone. 甚至Mac桌面也可以播放文件。我手动将视频文件推入iPhone并可以播放。所以视频格式没有问题。当我点击链接 iPhone 打开视频播放器（网页内）时，什么也没有发生。

我已经解决了我的问题。添加范围功能后（可以使用播放器滑块寻找任何地方）iPhone 可以播放视频。

            // Calculate etag
            String etag = Integer.toHexString((file.getAbsolutePath()
                    + file.lastModified() + "" + file.length()).hashCode());

            // Support (simple) skipping:
            long startFrom = 0;
