AC3Filter Taking Over

[rickgillyon]

I have a new clean intstall of v9 using the Windows Installer latest RC (9.0.4.232) in Win10 64, and I'm using LAVFilters for all audio and video, EVR. Except I'm not. LAV Audio is specified in Sage, but AC3Filter always takes over and LAV isn't used. Any ideas why?

SageTV has a setting to always swap for AC3FILTER ... it Is on by default you can turn it of by setting to 0

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Frey Technologies\Common\DSFilters\AudioDec]
"AlwaysSwapForAC3Filter"=dword:00000001

Thanks, that key wasn't there, when I added it, no effect. I guess I'm using AC3Filter!

Did you search for the Frey Tech key and drill down from there? On a 32 bit system the WOW part of the registry path wont be there.

Yes, it's a 64-bit system and I found the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Frey Technologies\Common\DSFilters branch, just no AudioDec.

Odd. I tested this during installs and Adding the AudioDec and setting it to 0 worked to not force AC3.

Not here. Not a biggie, only found one video so far where AC3 was a problem.

One thought. Perhaps sage is not reading the registry...older installs had this issue..

Try running sage as admin and see if it reads that setting. If so, then the permissions in the registry need changing so "everyone" has access to all the levels below and at Frey...

Neither running as admin or setting registry to Everyone, Full Access made any difference.

That code is also written so that it only swaps out for AC3 Filter if you have either the "SageTV MPEG Audio Decoder" or the "SageTV MPEG-2 Audio Decoder" selected. So if the LAV filters are selected...it shouldn't be using AC3. Can you post your log file from when you reproduce the problem?

Attached...

Try setting this in your properties file:

videoframe/dca_audio_decoder_filter=LAVF Audio Decoder

For some reason we have the following behavior in the code...probably because it solved most people's problems with DTS (DCA) playback and because the audio decoder usually selected in the UI was only good for AC3 or MPEG audio.

      // Check for a format specific audio decoder
      if (sage.media.format.MediaFormat.AC3.equals(audType) || sage.media.format.MediaFormat.MP2.equals(audType))
        audDec = Sage.get(prefs + AUDIO_DECODER_FILTER, "SageTV MPEG Audio Decoder");
      else if (audType.length() > 0)
        audDec = Sage.get(prefs + audType.toLowerCase() + "_" + AUDIO_DECODER_FILTER, "");
      if (audDec.length() > 0 && !"Default".equals(audDec) && !Sage.rez("Default").equals(audDec))
        setAudioDecoderFilter0(pHandle, audDec, null);
      else if (sage.media.format.MediaFormat.DTS.equalsIgnoreCase(audType) || "DCA".equalsIgnoreCase(audType))
        setAudioDecoderFilter0(pHandle, "AC3Filter", null);

In your case, the audType will be DCA. So it won't use the normally selected audio decoder. It then looks for a format specific one; which you probably don't have defined...which then caused it to fall through and use AC3Filter. I had totally forgotten about this type of thing.

I actually just uninstalled the AC3 Filter and audio is now using LAV Audio decoder

Thanks, I added that, and Sage started using LAV for most videos. That particular one from the log won't play with LAV, failing, which I guess shows the value of dropping through to AC3 after all...
