[QUOTE="ajp8164, post: 593876, member: 64375"] [b]Re: AcrSoftVideoDecoder - Attempted to read or write protected memory[/b] In looking through the code and doing some simple debugging I see that this problem arises from a call to render the graph for the video connection pin (not sure if I am saying that correctly). The exception comes out of the highlighted line below (which calls into Render(ppinOut) inside the ArcSoft Video Decoder AX driver). Not sure what is new in MP that is causing this... [CODE] public static void RenderUnconnectedOutputPins(IGraphBuilder graphBuilder, IBaseFilter baseFilter) { if (baseFilter == null) return; int fetched; IEnumPins pinEnum; int hr = baseFilter.EnumPins(out pinEnum); DsError.ThrowExceptionForHR(hr); if (hr == 0 && pinEnum != null) { pinEnum.Reset(); IPin[] pins = new IPin[1]; while (pinEnum.Next(1, pins, out fetched) == 0 && fetched > 0) { PinDirection pinDir; pins[0].QueryDirection(out pinDir); if (pinDir == PinDirection.Output && !HasConnection(pins[0])) { FilterInfo i; PinInfo pinInfo; string pinName = string.Empty; if (baseFilter.QueryFilterInfo(out i) == 0) { if (pins[0].QueryPinInfo(out pinInfo) == 0) { Log.Debug("Filter: {0} - try to connect: {1}", i.achName, pinInfo.name); pinName = pinInfo.name; DsUtils.FreePinInfo(pinInfo); } } ReleaseComObject(i.pGraph); [COLOR="Red"][B]hr = graphBuilder.Render(pins[0]);[/B][/COLOR] if (hr != 0) Log.Debug(" - failed"); } ReleaseComObject(pins[0]); } ReleaseComObject(pinEnum); } }[/CODE] [/QUOTE]
