Question

flash media server 4.5 questions

I have some questions regarding 4.5 and deciding which version we must license (FMIS or FMS). Obviously there is a huge price difference and as this is within a local network we don't require encryption or multicast. Here is the scenerio we need to stream live DVR to mac, windows browser AND iPhone/iPad and devices running Android 2.2(Froyo)+. I need someone from Adobe to help us decide. Questions

1. I see DVR is now listed as a feature in Flash media server page. Does that mean its no longer exclusive to Flash Media Interactive server. For both http streaming and RTMP?

2. Previously in order to stream live to Adobe dynamic streaming, Flash media interactive server was required because a live segmenter had to be used. Is this still the case? Or can we just launch adobe live media encoder (FLME) and stream to flash media server.

3. Related to #2 can we switch between serving streams via RTMP or dynamic streaming without changing the format of the material on disk?

4.I was at a webcast for 4.x and remember being told that the latency for http live dynamic streaming was 20 seconds because of the repackaging that had to take place. Is this still true? What is the latency for iOS playback from ingest to playback?

5. For the iOS playback feature do the streams have to be in Adobe dynamic streaming format or can we just stream via FLME RTMP and trust it to do the right thing?

6. Does the iOS playback support DVR?

7. Does the Android plugin have good support for RTMP live streaming including DVR?

Looking forward to hearinng answers and upgrading to 4.5;-)

best,

Tuviah

    You should use FMIS becasue otherwise you cannot write a serverside script and use DVR . The streaming version will allow you to stream nothing but video. FMIS will allow you to leverage the sever to do all kinds of things for example you can make chats and send users message such as "Bob has logged off" when bob leaves. among many other things. If you plan to build robust applications you need Flash Media Interactive Server 4.5  or Flash Media Enterprise Server 4.5.

    Hi,

    There is a compare table at the bottom of this datasheet. Reading this should help you with some of your questions.

    http://www.adobe.com/products/flashmediaserver/pdfs/fms45_ds_ue_v1.pdf

    1. Datasheet will be able to help you with this. I undertand it to be interactive and upwards.

    2. I think you mean Adaptive RTMP streaming?

    3. In order for Adaptive RTMP streaming, you need the source to be presented in different bitrates.

    4. From what I remember the standard quicktime player requires 3 segements before playback starts on the iOS device using a segment size of 10 seconds. Now you can make these smaller but this means more packets being sent.

    5. iOS streaming will be via HTTP not RTMP.

    6. I do not know if 4.5 gives you control over the TTL of segmented video chunks, on dedicated live encoding appliances I have been able to manually configure these to allow full rewind of a live show.

    7. I would expect so. I am still reading up, look here:

    I can answer a few of these questions:

    1. Recording as far as I'm aware is exclusive to the interactive version. Maybe an Adobe rep can tell us different...

    2. I'm actually unsure of what Adobe dynamic streaming is. Research for me to do. You can always launch FMLE and stream to the server, both the streaming version and interactive

    3. Depends on how you switch I would think, but either way it makes no difference to flash as long as it has the decoder for what you are streaming. FMS is just the messenger.

    4. You're going to get latency no matter what. Quicktime won't let you do any different. This is an issue for Apple, not Adobe.

    5. It won't be streamed out over RTMP at all. It's always HTTP from what I understand.

    6. What do you mean? Can you seek back in a live stream? That's a good question.

    7. The Flash Player for Android is just about as powerful as the desktop version. You can do just about everything with it.

    thanks for attempting to answer. I really need someone from Adobe to answer these. My company needs to make a choice soon to use FMS or FMIS!!!
