Using S/PDIF -> Video speeds up

Hi LaFouine, Could you do a little test for me ? Try reclock 0.96b with your Fortissimo III and do the following (be warned that this test can lead to a BSOD :D) : - save all your work - configure your Fortissimo in multi-channel in its control panel - Open a DVD in media player classic, and make sure multi-channel mode is enabled (you can check that reclock see at least 4 channels) either with AC3filter or Intervideo Audio Decoder - enable "hardware resampling" in reclock On my Fortissimo II (4 channels) i get a BSOD on Win XP after a few seconds when doing that ... The BSOD occurs in cwcwdm.sys (it's the sound card driver) ... Thanks !

I'll do the test, but you'll have to wait until tomorrow, 'cause I'm talking about my home PC... By the way, what means BSOD (for sure i'll discover it by myself, no ? :scared: ) Will this help to diagnoze my S/PDIF problem ? BTW, I'm working with W98SE. Anyway, thank you for you work and help A+ LaFouine

I also sent you an email @ nerim.net talking about the same subject, 'cause I couldn't post in Doom9. Sorry for double posting...

I did the test you asked me. Everything went fine. The first time I ran Media Player Classic, sound was crap, but second time everything was OK. Will ReClock work in this case with S/PDIF enabled ? I send you by mail a screen copy of ReClock (can't add an attachement in the forum, don't know why). See you

a BSOD is a Blue Screen Of Death :) Seems like they fixed the drivers for the Fortissimo III :) I don't think i'll be able to support SP/DIF in reclock, i don't really know how SP/DIF really works in directshow, but i think it's not feasible. Sorry

@ Valex : Could your SpeedMachine filter help me solve my problem ?

No unfortunatly i don't think it can help with your problem :(

My configuration: W98SE DirectX8.1 sound card : Fortissimo III 7.1, driver v4089A, CPL v4109 video card : GeForce 2 MX 32 I always use WMP6.4 to play my DivX, but problem is the same with other players. As soon as I configure my sound card in S/PDIF passthrough and the DirectShow filter in S/PDIF (whatever it is : Intervideo, AC3 filter, Cyberlink), sound is correctly sent to my external decoder, but video is jumpy. It goes to 3' in the first second, then plays accelerated, then jumps again, etc. It's like the clock of the soundcard was completely wrong when the sound is not decoded by the soundcard. Since this clock is used to play de video (I read an article of Ogo talking about this), perhaps it can't play video correctly anymore. Note that when I use PowerDVD to play a real DVD with S/PDIF, eveything is fine. Thank you for your help.

@LaFouine Could your SpeedMachine filter help me solve my problem ? Agreed with ogo. I do not think it can help. You said that with new version WMP crashes. So now we need to know why. First download Graphedit program: (or from doom9's downloads). Unpack and run it. Then File->RenderMediaFile->something with ac3 sound. Will it crash? If not try to play it. If it crashs try to run it again and add filters (Graph->Insert Filters->Direct Show Filters): AC3Filter (will it crash at this point? Also if you open ac3filter's group you'll see some info, including path where it was registred. Is it really there?), Avi Splitter, File source (Async) (it will ask file to open) and Default Wave Out renderer (it is in Audio Renderers section). Then connect: Async File Reader output to ac3filter's input (it will be made through AVI Splitter) and ac3filter output to Default WaveOut renderer. Then try to play it. Will it work, will video jump?

@LaFouine Yes, I already know what it may be. I think I'll prepare new version today.
