Using avisynth in realtime

[ya_vanka]

Hi all!

Is it possible to use avusynth not for postprocessing, but for realtime filter usage?

I need to apply filter to video stream being recieved by lan. So I get video data in realtime, write it to file and show it to the user. Can't understand how can I use avisynth in this case.

Please, help!

realtime processing is almost impossible for most filters

There is no problem with filters. When I apply filter (DePan) in postprocessing it show result in "realtime".
The problem is how to transmit video data being recived in realtime to the filter?

yes you can use graphedit to buid a suitable graph, remove the videorenderer. Save as grf-file. Open the grf file in an avisynthscript (define fps and disable seeking).
Or you can use ffdshow (avs scripting is built in)

But what is the way to put video data to filter from lan (IP address) or from file that continues to be written in?
Installed ffdshow but don't see how can I do that.

define fps and disable seeking
Is it the way to open file that continues to be written in? If so, could you give an example of defining fps and disabling seeking.

If you want to stream a video in your home LAN area, you can give Universal Media Server (http://www.videohelp.com/tools/Universal-Media-Server) (a DLNA compliant UPnP Media Server) a try.
It requires the latest Java version to run the program.

But the AviSynth is completely customizable with its own variables, in the "Transcoding Settings" section.
You can check out their forum (http://www.universalmediaserver.com/forum/) for extra help.

I've not used the custom Avisynth, so I can't offer much beyond that.
I only use UMS to stream movies without any extra transcoding.

No, it's not for home lan. It's for transmitting video from remote device.
