TV-Server crashes on scanning channels with Hauppauge WinTV HVR-900H (1 Viewer)

[Curry]

Considering it's also an update to the issue mentioned in this thread: morpheus' CI-updating test build does not solve my issues.

Something I'm curious about - it appears Hauppauge and other TV-card manufacturers don't bother to cooperate with HTPC software developers on integration of their products. Are they just ignorant about the reason a lot of their customers buy their products? It's not like their own WinTV software is worth a shit, and the whole idea is seamless integration for us end users. I kicked them in their own forums, hopefully they'll listen

Keep up the good work anyway guys, and whenever there's new stuff to test I'm up for it

New update:

I've did an SVN Export of the whole TVServer trunk and did some local testing with a custom self-written app already Weird thing is that my test program scans and recognizes all channels, but the CI interface won't show up on my laptop. I've isolated it to the following line of code:

DsDevice[] capDevices = DsDevice.GetDevicesOfCat(FilterCategory.AMKSCapture);

For some reason it's a no-show there while it should be in that category according to the core code. When I have more time I'll debug it some more. Is there some trick to trigger DirectShow in a rescan of capable devices?

Reinstalling the Hauppauge drivers fixed the undetected filter problem mentioned above.

So I went debugging, and found a 'probable cause'. Can't debug for shit on my setup though so please help me review whether this code change is bullshit or not

In TvCardDvbBase.cs, function TvLibrary.Implementations.DVB.TvCardDvbBase.AddWinTvCIModule, line 776 reads as follows in the current trunk:

      hr = _capBuilder.RenderStream(null, null, tmpCiFilter, null, _infTeeMain);

This consistently returned status 0x80004005, causing the code to retry adding the device in several different modes.

I changed it to:

      hr = _capBuilder.RenderStream(null, MediaType.Video, tmpCiFilter, null, _infTeeMain);

Specifying the media type explicitly caused it to return a proper 0, and have the CI added to the graph as it should. After this it fails on connecting the inftee main to MPEG2 demux with code 0x80040217 or "No combination of intermediate filters could be found to make the connection", but that is probably caused by me debugging on a semi-setup laptop without a proper MediaPortal install.

Attached is a recompiled 1.0.2 build of tvlibrary.dll - if anyone with another WinTV CI setup can check it that would be cool

i could check, but i will need a tvlibrary based on latest svn from sourceforge.
could you compile me one please?

But of course Attached is the fresh SVN-trunk based 1.0.3 build. I did have to disable Digital EveryWhere FireSAT support for this build since the code relies on new C# features my VS2k5 doesn't support

really ?! I didn't noticed that I introduced such new things...

3 actually, but I fixed the other 2 in my local build. In Encoder.cs:

      string[] videoEncoders = new[] { "InterVideo Video Encoder", ... };

'Implicit typing' is a new language feature, for old C# you have to explicitly use:

      string[] videoEncoders = new string[] { "InterVideo Video Encoder", ... };

The FireSAT code uses an implicit shorthard struct constructor at line 190 of DigitalEveryWhere.cs which is a new feature as well.

Tested with this build, and things are still working.
but as you know, i did not had issues/crashes before either.

Thanks, great I'll try to deploy this build on my live systems then and if that doesn't give problems build a proper patch
