FFDshow / ac3filter s/pdif and video with ac3

[vanleeuwen]

Hi,

Great software but i have 1 big problem that i can't fix.

This is about 2 groups of video files. 1 working with ac3filter and not FFDshow and the other working with FFDshow but not ac3filter.

I find ac3filter has always worked better than FFDshow for s/pdif so i am using that by setting it to passthrough.

Then .avi files with ac3audio made with AutoGordianKnot play video but no audio but .mkv (tv shows etc) work fine.

I read some posts that said that the fix was to use ffdshow so i reset the setting back to that and yes the .avi files works but now if i try to play the .mkv with s/pdif passthrough on ffdshow it goes to a black screen and will not play at all. If i don't select passthrough i don't get 5.1 sound but the video plays.

So i can have my .avi files with no sound but 5.1 on .mkvs or both with 2.0 or .avi with 5.1 but .mkv not working at all. I want 5.1 on both .avi and .mkv can any one help ??

I have tried playing with the settings in both FFDshow and ac3filter but can only ever get 1 file type to work in each.

These are examples of teh 2 files types

Wow thanks for the quick reply. I am using windows 7 32bit. so do i tick Disable Microsoft's audio decoder ? as i don't have any option called Microsoft Audio codec. If that is the one won't it break my live tv as per the note ?

thanks

I found the cause its the Subtitle Control on the config tap. If you set it to "No Subtitles" (which is what i wanted as i don't ever need them) then the .avi files don't have sound. Very strange but there you go. I guess i will have find another way of stopping the subtitles from showing up.

[Shark007]

Yes, thats the codec i meant.
I really don't know about it breaking LiveTV;
I put that note there to play it safe. I don't have the hardware to test it properly.
You can always uncheck it if it breaks livetv to re-enable it when you want to use livetv.

Hi,

This is my first post. First, thanks for this great software, Shark007! I love codec packs again! jejeje

I had some problems with AC3 in AVI. Then I arrived to this thread, and I have disabled Microsoft audio decoder, and now everything works perfect!

Thanks for the tip!

I have curiosity... What exactly does the toggle "Disable Microsoft's Audio Decoder"? I have made a diff with two exports from the registry (before and after applying) and found nothing... Can you explain me what it does?

Also, I can't test if LiveTV is broken when disabling Microsoft audio decoder, but if someone can confirm it, it will be good to know for the future.

Thanks a lot!
