video标签用自己写的文件流在ios的safari里播不了?报错

video标签读的是java写的文件流（MP4视频编码是h264），页面代码如下：

	<video width="320" height="240" controls="controls">
  		<source src="http://192.168.254.107:8080/testvideo!test.do" type="video/mp4" />
  		您的浏览器不支持video标签
  	</video>

java代码如下：

	public void test() {
		try {
			File f = new File("F:/MyWorkSpace/wrote/c测试用文件/cath264.mp4");
			if (!f.exists()) {
				response.sendError(404, "File not found!");
				return;
			}
			BufferedInputStream br = new BufferedInputStream(new FileInputStream(f));
			byte[] buf = new byte[1024];
			int len = 0;

			response.reset();
			response.setContentType("video/mp4");
			response.setHeader("Accept-Ranges", "0-" + f.length());
			response.setHeader("Content-Range",
					"bytes " + 0 + "-" + (f.length() - 1) + "/" + f.length());
			response.setHeader("Content-Length", f.length() + "");

			OutputStream out = response.getOutputStream();
			while ((len = br.read(buf)) > 0)
				out.write(buf, 0, len);
			br.close();
			out.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

视频在PC端和安卓手机的浏览器中均可以播放，但是在iPhone中的Safari上放不了。

PC端运行时系统也不会报错，在Safari上运行时会报以下错误：

如果把视频放到工程里，video标签直接引用，视频在Safari里是可以播放的

	<video width="320" height="240" controls="controls">
  		<source src="${path}/jsp/reception/cath264.mp4" type="video/mp4" />
  		您的浏览器不支持video标签
  	</video>

左边的视频是引用的文件流，右边是直接引的视频

求大神帮忙解决一下，谢谢！
