RE: [Flashcoders] VitalStream Bandwidth detection
looks like bwcheck to me. i'd just use p_bw in a condition where p_bw is detected bandwidth. if p_bw is less than than x play stream1, else if p_bw is greater than x and less than y play stream2, else play stream3. ie. stream1=56kbps; stream2=150kbps; stream3=300kbps; i usually run the bwcheck on an interval several times and get an average bw figure to go by and even dynamically change streams-- you can do it seemlessly by bookmarking ns.time and seeking to it once new stream has loaded. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Brian Weil Sent: Tuesday, October 03, 2006 12:38 PM To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] VitalStream Bandwidth detection Does anybody have code to detect users bandwidth on VitalStream?

RE: [Flashcoders] VitalStream Bandwidth detection
> Hey Brian. Can you give a little more info? Are you passing a smil > xml file to the flv player or are you trying to detect based on the > bandwidth profile being returned from the server? I think you would have to be familiar with the vitaltream service to really understand my question. I'm using their flash streaming service and they have a specific protocol for accessing the video stream. I'll explian the service briefly: - They host all of your .flv video content and mirror it worldwide and stream using Flash Media Server. - They offer two ways to display your .flvs: - 1. embed their pre-compiled .swf player by passing parameters to the swf via html. - 2. a "custom player" where they provide the .flv source, you customize and compile. The XML file is telling flash the fastest mirror to connect and stream name containing the flv files. This stream name works fine when there is only one filename being passed but when multiple filenames are passed the code fails. There is no bandwidth detection in their source code so it does not know which stream to deliver. If anyone has created a custom VitalStream player they may have already created this code. VitalStream will not release the source code for their pre-compiled players. I hope you understand this because I'm confusing myself trying to explain! I can send you the player source offline if you want to take a look.

RE: [Flashcoders] VitalStream Bandwidth detection
VBR and Flash Media Server stream length detection could be the source of this problem. I have done work for VitalStream before and seen this issue come up with MP3 streaming at least. To get a more detailed answer, this is a question better asked on the Flash Media Server forums: FlashMedia [EMAIL PROTECTED] - rob sandie -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brian Weil Sent: Tuesday, October 03, 2006 12:38 PM To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] VitalStream Bandwidth detection Does anybody have code to detect users bandwidth on VitalStream?

Hey Brian. Can you give a little more info?
