    Hi Guys,

    I have run into a problem creating graphs when loading certain media files into GraphEdit, GraphStudio and GraphStudioNext. GraphStudioNext returns the following error message:

    VFW_E_Unsupported_Stream
    (0x80040265)

    Cannot play back the file. The format is not supported.

    This would seem to be a nonsense message, as the system has all the required registered codecs it needs to play both audio and video files and they all play perfectly using Windows Media Player or MPC-HC with the required external codecs selected as preferred. I also get the same error message when using GSpot. All video files seem to be effected (mpeg ts,and mp4), however, the graphing apps all render most audio files such as ac3, mp2, mp3,and wav - but not aac and m4a. GSpot also works with ac3, mp2, mp3,and wav audio files.

    I am running 32-bit Win7 Pro sp1 on a Samsung nc110 that uses an Intel Atom N570 1.66GHz dual core processor with Intel integrated graphics and 2GB of RAM. I have also tried 32-bit Win8 Pro on the same machine but get the same error, so it does not seem to be a case of a broken OS. DXDiag.exe reports that there are no problems with DirectX 11 and Dependency Walker didn't find any problems when loading the graphing apps.

    A clue to solving the mystery might be that only video and the more recent mpeg-4 spec audio files seem to be effected. The only thing that I can think of that might be causing the problem is some obscure unmet software dependency. If anyone has a similar spec netbook it would be interesting to know if they have experienced the same error when running GraphEdit and any help would be greatly appreciated.

    You provided lots of information regarding audio, but video information for these problem files is lacking. "MPEG ts and mp4" covers a lot of territory. What kinds of video do the problem files contain -- MPEG-2, H.264 or something else?

    One of the video files that would not render was a DVB-T recording. I think it is mpeg transport stream (ts).

    I can't help you over here in ATSC land, especially without a netbook, but your chances for getting help might improve if you uploaded some small clips that do not work. Good luck.

    Not all DirectShow applications build the playback graphs in the same way. This is the reason why some files are OK for WMP, but are not OK for MPC-HC or Pot Player (and vice-versa). Avisynth's DirectShowSource is yet another different beast. If you want to force Graphstudio to play an apparently-problematic file, you have to build the graph manually --- which may mean a lot of trials-and-errors. Also, many filters still work better with DirectX 9 than with DirectX 11, so you'd better install DX9 too ^.^;;

    Many thanks guys for the input, I will try installing DX9c and see if it makes any difference and get back to you latter.

    I have done some more testing and found a couple of video files that GraphStudioNext handles correctly. One is an mpeg-2 main video with mpeg-1 layer 2 audio in an mpeg ps container and the other is a mpeg-4 with mpeg-1 layer 3 audio in a AVI container. Here is the output from media info:

    As stated earlier, all the files play faultlessly in Windows Media Player, so the problem seems to be with GSpot and the graphing apps not connecting to the relevant splitters/codecs/renderers.

    Did you know that MPC-HC has a context-menu item which shows the DirectShow filters that are being used

    Besides: if you run MPC-HC and Graphstudio at the same time, you can tell Graphstudio to "connect" to the functional playback graph by pressing "CTRL + G"

    Regarding WMP (which SUCKS by definition), you will need to have the DirectShow Filter Graph Spy:

    I installed DX9c (which also needs .Net 3.5) on Win8 Pro, but am still getting the same error message. I use MPC-HC's Play > Filters menu quite a lot, but did not know about the Ctrl+G trick which I will experiment with, thanks for that info.

    How does one load a problematic video into GraphStudioNext to experiment with filter combinations? I have tried using the Graph > Insert File Source (Async.) method on file1.ts above, but I end up with a file source that only has one output pin. File1.ts is a DVB-T recording and should have, video, audio and subtitle pins. The video pin should connect with MS DTV-DVD Video decoder, and the audio should connect with MS DVT-DVD Audio decoder - the two default decoders on Win8.

    AFAIK, the latest DirectX9 update is a standalone package, which DOES NOT depend on the silly dotNET frameworks. UNLESS Áicro$oft themselves have screwed the latest installer of the DirectX9 package and/or Windows 8, go figure.

    Anyway: TS files can be demuxed by LAV Splitter, AV Splitter, or the standalone MPEG Splitter from MPC-HC.
    Do you have any of these

    Thanks guys. As you expected the problem was due to a lack of an external splitter. I had Haali installed, but it did not work well with GraphStudioNext for some reason - only produced a video output pin. I then tried AVSplitter and LAV Filters which both worked. I also had a problem with connecting GraphStudioNext to a remote running graph - in this case MPC-HC playing a DVB-T recording of a TV show. I got an E_NOINTERFACE (0x80004002) error. The problem turned out to be an out of date proppage.dll, when version 6.6 was registered I was able to produce a graph of the filters that MPC-HC was using to play the file (see attached dvb-t.jpg).

    There is one further problem, I manually constructed a graph of the same DVB-T file (see attached predators.jpg) which plays in GraphStudioNext, but so far have not been able to work out how to display the dvbsub subtitles. I have VS registered, but it does not seem to be compatible with any of the subtitle pins, and the two filters that MPC-HC is using (see attached dvb-t.jpg) must be internal, as they are not listed when using a filter manager such as Radlite.

    If I may be so (b)old....what is the point of GraphEdit, GraphStudio and GraphStudioNext?
    Why do these programs exist.
    Under what circumstance would you need these programs?

    Technically speaking, they are development tools for computer programming using DirectShow.

    You would need them to test what filter combinations and or capture device settings work best if for example you were writing your own capture program or your own media player software. They would save you the trouble of re-compiling your program each time to test a new filter chain.

    However, they can be used on their own to play media files or (with a capture device) to capture video and audio. They may allow access to controls that media player software and capture programs don't allow users to configure.

    I've attached a short dvb-t video clip that has subtitles. VSFilter does not seem to be able to render dvbsubs, if anyone has a solution to the problem I would be interested in hearing from them.
