Windows Server Forum / Windows Media Server / February 2008Windows 2008 Media Services UDP push
Will the media services in Windows 2008 have the ability to accept a push from an encoder over udp using rtsp or will http still be the only option? Thanks, Mike >Will the media services in Windows 2008 have the ability to accept a >push from an encoder over udp using rtsp or will http still be the >only option? Windows media encoder and Expression media encoder are the only ones I know for sure are compatible - I haven't tried real encoder for a while so I can't say if it supports UDP/RTSP transports. In both the MS cases, they only output http streams, though I guess it's possible to patch into Expression as some parts of the Publish functionalty are extensible. I haven't seen anything updating the server to use those transports in the docs so far, so I imagine you'd have to find another way to push the content up to the server filesystem (i.e. sabing first then FTP ?)

We have our own encoder but use WMS for delivery. Is TCP the only way to push live streams to WMS from a remote encoder (server 2003/2008)?

Well the thing is, TCP is in use because it's guaranteed (reliable) transfer with retransmit if content goes missing en route. If you switch to UDP, what would the server do on a content break due to routing issues? In all likelihood it'd consider the stream stopped and drop the publishing point and all clients. The sender has no real idea if the receiver got that content, and with UDP it's required not to care and just send anyway (because it's connectionless) WMP and other players can use UDP because from a client viewpoint - it's not absolutely critical to have small dropouts because they have buffers (like the server) as well as scaling back and interpolating the video or audio playback to mask interruptions. And of course, humans don't notice the odd frame or 10 going missing that much. I'm pretty sure Quicktime Broadcaster works that way with DSS so I think it's probably a required feature rather than (say) a bug ;-)) HTH Cheers - Neil ------------------------------------------------ Digital Media MVP : 2004-2008 http://mvp.support.microsoft.com/mvpfaqs On Feb 21, 1:36 pm, "Neil Smith [MVP Digital Media]" <n...@nospam.com> wrote: > >> >Will the media services in Windows 2008 have the ability to accept a > >> >push from an encoder over udp using rtsp or will http still be the [quoted text clipped - 30 lines] > ------------------------------------------------ > Digital Media MVP : 2004-2008http://mvp.support.microsoft.com/mvpfaqs Neil, I agree with your points about TCP however I view our encoded content being pushed to the server as WMP views content being streamed to it (if some frames drop, that's okay). If I were to have a UDP custom datasource for WMS that could buffer the pushed content, then it seems that I'd be able to provide some fault tolerance plus unload some of the communication burden from the encoder. Additionally, if I were to lose the stream for any amount of time, the publishing point would come back up as it will be a push. Mike Hi all, and one day, maybe Windows media encoder will accept a stream for input. if someone have a solution during the time, i'll take it Regards Wardead >>> >Will the media services in Windows 2008 have the ability to accept a >>> >push from an encoder over udp using rtsp or will http still be the [quoted text clipped - 31 lines] > Digital Media MVP : 2004-2008 > http://mvp.support.microsoft.com/mvpfaqs If you have an Axis camera on the network, Axis have a driver available which accepts the camera input stream and pretends to be a local MJPEG hardware device to WME (so that it can be used to transcode and stream the camera content) For usage and download, see http://www.axis.com/techsup/software/capture_driver/software.php and http://www.axis.com/techsup/software/capture_driver/files/capture_driver_um.pdf or take a look at Unreal media encoder/server to grab and compress the streams : http://www.umediaserver.net/umediaserver/index.html HTH Cheers - Neil >Hi all, > [quoted text clipped - 40 lines] >> Digital Media MVP : 2004-2008 >> http://mvp.support.microsoft.com/mvpfaqs ------------------------------------------------ Digital Media MVP : 2004-2008 http://mvp.support.microsoft.com/mvpfaqs |
