video標(biāo)簽用自己寫的文件流在ios的safari里播不了，求解決辦法

video標(biāo)簽讀的是java寫的文件流（MP4視頻編碼是h264），頁面代碼如下：

<video width="320" height="240" controls="controls">
    <source src="http://192.168.254.107:8080/testvideo!test.do" type="video/mp4" />
    您的瀏覽器不支持video標(biāo)簽
</video>

java代碼如下：

public void test() {
        try {
            File f = new File("F:/MyWorkSpace/wrote/c測試用文件/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();
        }
    }

視頻在PC端和安卓手機(jī)的瀏覽器中均可以播放，但是在iPhone中的Safari上放不了

PC端運(yùn)行時(shí)系統(tǒng)也不會報(bào)錯，在Safari上運(yùn)行時(shí)會報(bào)以下錯誤：

如果把視頻放到工程里，video標(biāo)簽直接引用，視頻在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" />
          您的瀏覽器不支持video標(biāo)簽
      </video>

左邊的視頻是引用的文件流，右邊是直接引的視頻

下面的代碼可以解決這個(gè)問題，但是手機(jī)訪問頁面，還是會報(bào) Connection reset by peer: socket write error 這個(gè)錯誤，希望能有解決辦法。
