Question

Im trying to implement a graphedit filter file i created. I am using 3ivx to encode and compress a video then save it to .mp4.

in my graphedit file i have:

Mpeg4s Decoder DMO (out0) -> (XForm In) 3ivx MPEG-4 Video Encoder (XForm Out)->

However when i put this to code, the pin (XForm In) and (XForm Out) cant be found, and therefor wont connect.

I added the running graph to DsRot to display the current graph and it showed the filter with (XForm In) and (XForm Out) pins unconnected.

I called

IEnumPins pinsx;
filter.EnumPins( out pinsx );

to try and get what pins are available but it doesnt store the names in IEnumPins, it stores object.

How can i find the pins associated with this filter?

Take a look at the FindPinByDirection function at Splicer.Utilities.FilterGraphTools (codeplex).

There is also a ConnectFilters function, which you probably can use:

public static void ConnectFilters(IGraphBuilder graphBuilder, 
            IBaseFilter upFilter, IBaseFilter downFilter, 
            bool useIntelligentConnect)
