查看底层代码发现，在 http_open_cnx 函数中，如果接收到重定向状态码，并且location_changed = 1，就会再次以http的方式发送rtmp的地址请求，这个就有问题，最后就返回了404状态码。
代码如下：
if ((s->http_code == 301 || s->http_code == 302 ||
s->http_code == 303 || s->http_code == 307) &&
location_changed == 1) {
/* url moved, get next /
ffurl_closep(&s->hd);
if (redirects++ >= MAX_REDIRECTS)
return AVERROR(EIO);
/ Restart the authentication process with the new target, which
* might use a different auth mechanism. */
memset(&s->auth_state, 0, sizeof(s->auth_state));
attempts = 0;
location_changed = 0;
goto redo;
}
在这个分支中，是否应该对s->location（rtmp地址）做rtmp连接处理，通过调用 ffurl_open_whitelist 函数，望官方维护人员解答，谢谢~
