Is there any way to use this filter under GraphEdit 9.04.78 ?  When I add the filter I get a file dialog - the same thing happened with my Elecard network source and I had to ignore the dialog and use the filters property page.  Unfortunately, your filter won't show a property page. So, I've tried several formats in the file dialog such as '{IP}:{PORT}' and 'UDP://{IP}:{PORT}' and am not getting anywhere fast.  Do I have to set up your filter programatically ?  I note that another user in this forum mentioned entering 'ip:port' on the 'input pin' ... this confuses me somewhat because this is a source filter with no input pin.   Being an eternal optimist I tried properties on the output pin... Please let me know where I'm going wrong. Q2. Ultimately i'm trying to render a push-mode graph for decoding UDP MPEG-TS carrying MPEG-4 with PAFF.  I have the CoreAVC codec which is working fine with a file source (Async) in pull mode using a file-based copy of the live stream... I just can't seem to connect it in push mode to a network source. The most luck I've had is with the Elecard NWSource filter + Elecard MPEG push Demux. ... and this gives me renderable audio pins and an H.264 pin that unfortunately wont connect any of my H264 decoders. Suggestions?  Can anyone recommend a source filter and demuxer combination that will take an MPEG-TS over UDP and present a video output pin in a way that can be connected, directly or indirectly, to CoreAVC Video Decoder ?

You cannot use network filters in GraphEdit directly because they are source filters and GraphEdit only allows you to use a file on disk as a source, not an IP.  You will need to set up the filter programmatically using either our SDK or DirectShow.  I would recommend using our SDK because we take care of the DirectShow stuff for you, all you should have to do is update the SourceFile property. The correct format should be "udp://ip_address[:port][/network_card] 2. The MPEG-TS should be able ot carry MPEG2, MPEG4, or H264 data. As for your CoreAVC Video Decoder, I'm not sure what this is and what it supports.  If it is a decoder that can decode either MPEG2, MPEG4, or H264 then it should be able to work with the MPEG-2 Transport Demultiplexer.
