flash - RTMFP 和防火墙/路由器

Question

我想使用 Flash 的 RTMFP 对等协议(protocol)，但我想知道它是否值得为主流受众开发？据我了解，它使用 UDP，除非用户的防火墙/路由器配置正确，否则它变得毫无用处。

这个问题有解决方案吗？

Answer 1

有这个:https://github.com/OpenRTMFP/Cumulus

不知道大家有没有看过。

我已经和开发商谈过了，显然它已经完成了 95%。

我不知道故障回复到 RTMP。这让我觉得整件事都没用。

任何人都可以进一步调查和评论吗？

我还将其添加到组合中:

The older RTMP operates over TCP port 1935 and falls back to tunneling over 443 and/or 80.

The newer RTMFP uses UDP and requires the ability to make outbound connections to 1935 and also higher port numbers in order to establish a server connection.

Running over port 443 and 80 UDP wouldn’t help, the firewall is likely configured to open up TCP 443 (HTTPS) and TCP 80 (HTTP) while still blocking UDP (Outbound UDP to be enabled).

The Flash Player can also be configured manually to use a TURN proxy, if you’re able to have the customer’s IT department install one to get past the firewall. In Flash Player 10.0, draft-ietf-behave-turn-08 is supported.

现在看这个: https://labs.ericsson.com/developer-community/blog/beyond-html5-peer-peer-conversational-video

他们能够执行 RTP/UDP，并且在两个客户端都位于 NAT 之后的情况下。

Most networks use some type of NAT (Network Address Translation), which complicates peer-to-peer connections like this. The ICE (Interactive Connectivity Establishment; RFC 5245) procedure allows for establishing connectivity even in the presence of NATs, using STUN/TURN servers.

这是否意味着使用 ICE 意味着 RTMFP 在嵌入浏览器之前可能是一个有值(value)的权宜之计？
