Forget the avermedia route Jean-Marc, iv'e been there and they have nothing thats of any help at all on their website.
The quickest way iv'e found of experimenting with Graphedit, is to drop one component on then right click on a pin and select render pin.
Try this with different components (Not just the avermedia ones) and also try dragging and dropping media files into the Graphedit window, you'll soon start to see which individual components like to talk to each other. :-)
I don't think i saved any of the filter graphs i was experimenting with, beacuse i was just playing to see which DS filters i had installed, but i'll have a look on my drive(s) see if i did.
I found a lot of info on this guys website http://www.pcpret.nl/develop/ when i was researching a different DVB-T device, and a lot of it is generally relevent to Directshow and BVB-T capture in general.
You may also want to download and install the latest incarnation of Videolan (VLC Player) that now has direct hardware control in it, so you can use a comfortable GUI to mess around with the DS Tuner and DVB settings.

Hi,
I need to create a simple DirectShow application for rendering component signal from the S-Video input. Many capture filters are availables (AVerMedia Capture, AVerMedia BDA Capture, AVerMedia BDA ATSC Tuner...) none of them seems to work at first glance but the solution might as well reside in proper graph building which is the topic I am asking about: can someone tell me the proper filter graph arrangment for this matter?
If this question is too specific, can someone tell me about the AVerMedia hardware used on the IQ506 model so I can try to find answers from AVerMedia.
Thanks for helping.
Hi Shawty,
I had done a bit of fooling around with Graphedit, enough for discovering that hardware was AverMedia but didn't want to spend too much time since it's on a hourly based contract (and I am a pretty honest person). So I thought that having the information from an official source would cost them less but your advice will make me feel ok with 'wasting time' since it appears to be the most productive way.
Thanks for the info, I'll post back my results when I have some.
Thank you for your help.
Regards
Jean-Marc
Any time jean-marc, but i wouldn't look at it as wasting time, i'd look at it as increasing my knowledge :-)
Prety much the same approach applies no mater what DVB-T device you play with, so it may be worth just getting a cheep plug in USB one for your own PC, that way you can play with graphedit at your own leisure.
Sometimes (Even on time sensitive contracts) you have to figure things out, in order to make them work efficiently, and even though we try to get the job done as efficiently as possible, sometimes there is more investigation to be done than there is actual solution building.
Iv'e had a look to see if i could find any filter graphs but iv'e no idea what i did with them, if i get 5 mins i'll hack one together on my TS-IQ512 and send it to you.

I'm trying to do about the same using DirectShow Filters in GraphEdit. So far, using "standard" arrangement (Tuner,Crossbar,Capture), I'm not getting any frame - only black. I may be missing something there - I usually build graphs for "standard analogic" capture cards.
Is there someone who succesfully built such a graph to capture using the s-video pin?
Thanks!
High likley hood that your not tuned to any usable signal if all your getting is black. Either that or your crossbar source is set to somthing like SVHS input, but thinking that your on the tuner.
If you can see blank, and graphedit doesnt complain, you are actually getting output from the video decoder & the crossbar, just the input is either not correct or not there.
Cheers
Shawty
PS: the info on this site http://www.pcpret.nl/develop/ will help.
I made sure to double-check that the video source in the crossbar was set to S-Video, and still nothing... Graph I have is something like that: "Tuner"->"Crossbar"->"Capture"->Render the preview pin. If I'm using S-Video, is the Tuner really necessary? If so, any specific parameters to set - only options are the channels, which are not needed.
Of course, there is something plugged in the s-video input, and I made sure it was correctly displayed in the only software I could get the video capture to work: Windows Media Center. All other software (MediaPortal, every single TV capture software I tested) do the same behavior as GraphEdit - black screen.
Thanks
Hmm... that doesn't sound good. If every bit of software fails with the same, then it sounds to me like you have either a driver fault of worse still somthing up with the hardware itself.
Try using VLC, play with the advanced streaming & recording options in that, if you still have no joy then i'm afraid nothing i can do to help.
To answer your tuner question : Yes. The tuner driver also includes the code to switch off the tuner input and switch on the others.
Cheers
Shawty
I already tried with VLC without any success - I get no video output in VLC, only time passing by, and no error message in the console...
I tried with the original installed driver and the latest that was available in Windows Update, without any success... I don't think there's an hardware problem, otherwise I wouldn't be able to get any capture in Windows Media Center.
Did you actually succeeded to build a working graph with the IQ512? I'm using the IQ80x, so maybe they don't have the same tuner hardware for those two variants...
Thanks again!
I did indeed, wel one that uses the tuner anyway. Only problem is i can't find a way to attach files to this post, otherwise i'd send you the jpg.

Analog Tuner -> BDA Crossbar
Analog TV Audio -> BDA Crossbar
Crossbar -> BDA Analog Capture (Vid Dec Out -> An Vid In, Aud Dec Out -> An Aud)
BDA Analog Capt -> Video Renderer
BDA Analog Capt -> Default Direct Sound Renderer
Works for me.
Cheers
Shawty
Thank you Shawty for your help!
Unfortunately, it seems that I have no BDA Analog Capture filter available... The only ones that are available are in the WDM section, and are specific to the hardware (AverMedia Capture, Tuner and Crossbar).
It thus seems that's it's a driver related issue or something like that...
Thats the ones you need. It's an Avermedia card thats installed.
Cheers
Shawty
Like i say Mysticx,
I guess your filter graph was the same as mine, and mine works for me so i'd have to say you got either a hardware or at the very least a driver failiure as per my previous reply.
Cheers
Shawty
Has anyone gotten this to work? I need to capture Svideo on the Iq826t also. I may return this Iq800 and get the iq507 if there is no solution.
I am trying to get video to show in Matlab and they say try to get it to work in AMCAP: http://www.mathworks.com/support/solutions/files/s1-1B4VP/AMCap.exe
If anyone knows how to build the proper graph, please let me know. Thanks!
