一早接到email 通知，FMS 3.5 正式開始販售，想想從它去年 announce 到現在開賣，還真是隔了很久，但正式販售代表的意義是 - 至少有 trial version 可玩了。
新版本功能看來很好很強大，只可惜就是沒有 AS3 支援，也沒有其它 scripting/language support，所以還是要繼續跟 AS1 打交道啊。
下面是 release note 裏看來的 new features (只列出我覺得有趣+值得觀察的項目，
詳細清單在這裏
)
[1b]*Plug-in architecture[/1b]
Integrate with other servers, back-end services, and workflows with the new plug-in architecture. Three classes of plug-ins for authorization, server access, and file access let you extend Adobe? Flash? Media Interactive Server 3.5 software with custom connectivity, security, and deployment options.
這點很重要是因為以前 FMS app 很容易被人家亂搞，自已寫個 fake client 就連去，結果浪費頻寬等問題一大堆，現在透過自製 plugin 門檻就高一點。
[1b]*MPEG-4 video recording[/1b]
mpeg-4 + HD 的重要性就不用多說了，現在不到 1080P HD 等級大概不用肖想吃 CDN 或 streaming content 這塊了，所以這次從 encoder, DVR 到 dynamic streaming 都支援，算是非常符合時勢
[1b]*AMF3 support[/1b]
有點雞肋，but nice to have.
[1b]*Easier implementation
*More secure content delivery[/1b]
[1b]Lock down your high-definition content and communications with enhanced stream protection and server-side security. Encrypted H.264 streaming is now supported — with the encrypted Real Time Messaging Protocol (RTMPE), you get higher performance at 128-bit encryption strength. In edition with RTMPE, protect SWF files from being reused or modified, and help prevent unauthorized connections with improved SWF verification. Use the plug-in architecture to create custom, real-time rights control by validating with external services such as LDAP or SOAP.
[/1b]
新增支援 windows server 2008, red hat 5.2, RTMPE 加密串流到 air runtime
[1b]*Multipoint publishing[/1b]
Use multipoint publishing to remotely inject new live or prerecorded streams into your delivery system to quickly add time-sensitive content. This is most useful when working with a content delivery network (CDN) or distributed servers.
這個聽起來很威，但全世界有能力玩這種等級的 CDN 大概沒幾家吧，例如 MediaTemple, BrightCove 或少數幾個 in-house 的媒體。
[1b]*Stream data access[/1b]
Create dynamic thumbnails or video previews on the client side with the ability to take a snapshot of the streamed video (requires Flash Player 9 or later).
這個不算新鮮事，但在 fp9 裏實作手法可能更有趣，我推測是直接從 binary stream (byte array) 裏做 memory dump 然後生成 preview，這個要等裝起來玩後才能驗証了。
另外從 FMS 3 開始就支援一個 RTMFP 格式，如果你有在 follow MAX 2008，應該已經注意到讓每個人眼睛一亮的 p2p 功能(包含正 beta 中的
Stratus
service)，RTMFP 就是讓 p2p 成真的 UDP 傳輸格式，只是之前一定要用 FMS 才行，現在也可選擇不俱 Audio/Video 能力的 Stratus (or better yet, can we have standard SIP support ?) 來玩同樣的事，就看口袋深度囉…XD
