DTVViewer is whitout video for h264

Since the DTVViewer sample mainly use intelligent connect to build its graph, it is not aware of the kind of video codecs used by the broadcaster.

Anyway, H.264 is not handled by the MPEG2 Demultiplexer prior Windows Vista This mean that under XP, the graph must be built manually and the sample don't works in that case.

Next, you must have a H.264 decoder and none are provided prior Windows Vista.

Finally, most Codec Packs are known to break the DirectShow stack. Try your code on a clean installation of Vista or Seven...

thanks for help .
i run code under Windows 7 . and i can't change windows because of its windows is our goal .
i am a beginner developer and very very try to run this sample in Seven but only play sound and doesn't support video . i understand channels our country is video_type h264 .
i use K-Lite Codec Pack final version .
please help me for this problem and if is it possible send me upgrade sample .

Uninstall "K-Lite Codec Pack". Windows Seven have everything built-in to read a H.264 DTV broadcast using the DTVViewer sample.

I have suddenly remembered something. The DTVViewer from the samples archive is not the latest one. I made corrections two months after the release (23 months ago) and we never had the occasion to make a repack of the DirectShowLib samples archives.

The corrections are available using the CVS. Make sure that you use the latest source version :
http://directshownet.cvs.sourceforge.net/viewvc/directshownet/directshowlib/Samples/BDA/DTVViewer/

Also, to debug further, you can try to attach GraphEdit on your running application (with a debug build) and make sure that 1) the graph is correctly build (everything is connected) and 2) the MPEG2 Demultiplexer is correctly auto-configured by the tune request

http://directshownet.cvs.sourceforge.net/viewvc/directshownet/directshowlib/Samples/BDA/DTVViewer/

Hi. I'm having the same problem. I'm trying to capture Portuguese DTV (H.264), the result:
1 - the audio is correct,
2 - the video is just black.
I tried with VLC and the video works correctly so the capture card is working correctly.
I'm using Windows 7. Has anyone solved this problem?

Thanks for any help.
