ffdshow tryout project : HD audio discussion

[SamuriHL]

Same result with 2.9.9 (the newest old version I have kicking around). I'll send him an email and bring this to his attention. Thanks again for your help!

Supposedly the new version of MKVMerge (4.0) causes issues with subtitles which is why I have not upgraded. You can download an older version here:

Thanks! I'll grab the latest 3.x version but I suspect it won't change much. 2.9.9 had the exact same problem. I've sent an email to Mosu to see if he has time to look at this issue. I know it affects a lot of people because I've seen various posts the last few months in both ffdshow threads and all attributed the issue to Haali. It's possible that it's a Haali issue but where it works with MakeMKV output I think it warrants a closer look. I'm really hoping this problem can be found and squashed as it'd be very beneficial to everyone.

You can download all recent releases from http://www.bunkus.org/videotools/mkvtoolnix/win32/ and even older ones from the "old" subdirectory.

Then: I don't have the means to play back DTS-HD, and I don't have time to look into playback issues at the moment. Especially if everything's pointing to Haali's splitter. Please contact him for support.

[SamuriHL]

Thanks for the response, Mosu! I'll try to contact the author of Haali and see if they have the time to look at this.

Here is the issue I read about regarding using the latest MKVToolnix (version 4.0) and MPC w/ subtitles:

Hmmm. That seems very specific to MPC-HC and its handling of subs, though, yea? Unless I'm reading it wrong. If you use Haali to feed the subs to ffdshow, and disable MPC-HC's handling of subs entirely would that issue still show up? Perhaps I'm not reading it right. Again, MKV is still very new to me so I'm playing catch up on how it all works.

I have not confirmed since I have not used the latest MKVToolnix but I agree with you, it appears to be specific to MPCs handling of subs. Just trying to cover all bases of what the culprit could be (sounds like Haali is most likely the issue)

I honestly don't know. I sent him an email so we have to wait and see what he says. For myself I'll probably just redo the DTS-HD MA MKV's I'm having issues with using MakeMKV from my originals and call it good. Time consuming for sure, but, at least I know that works. That doesn't help everyone else, though, so, we'll see what happens. I'm also really concerned that Haali isn't splitting TS or M2TS files on my machine. I've got it set up in both 32 bit land using WMP and 64 bit land using MPC-HC. Neither of them play any audio or attempt to load Haali at all when I play a TS or M2TS file. This is not a good thing IMO.

[dbone1026]

I can confirm SamuriHL's findings. Haali + MakeMKV mkv + FFDShow plays fine with Bitstreaming for DTS(MA). Haali + MKVMerge mkv + FFDShow stutters like crazy with DTS(MA). Also, SamuriHL is able to get PGS subs in mkvs working with FFDShow but unfortunately I cannot. I tested this with WMP, MPC HC, and SageTV.

For now I will just stick with FFDSHow + MPC Matroska Splitter as that seems to yield the most reliable results.

[SamuriHL]

Thanks for testing! Very much appreciated. Still not sure why you can't get the PGS subs to work. I have no problem with that. They show up fine on the Haali menu and I can select between them with ease. I don't blame you for sticking with the MPC splitter. I would if I didn't care about PGS subs and WMP support. I need to get this working with Haali somehow.

Maybe someone else can test out PGS support. If anyone has a PGS MKV (created by MakeMKV) and is looking for the right to earn a hairy chest (yeah, don't really know what that means!) here are SamuriHL's steps:

- Install latest Haali
- ffdshow dxva video configuration:
Subtitles is checked in the tree on the left. Make sure all the formats are checked. Make sure embedded subtitles and subtitles files checked
- MPC-HC configuration:
Playback, uncheck auto-load subtitles
Internal filters make sure matroska is unchecked
External filters add ffdshow dxva video decoder, ffdshow audio decoder, and ffdshow subtitle filter and set all to prefer.

Play MKV in either WMP or MPC HC and see if PGS subs work. I have no problem selecting the subtitles but nothing appears. In fact, this method kills all subtitles from working (IDX/SUB as well).

[SamuriHL]

Yea, I have no problem with subs when I do that. Not sure what's up with your configuration. When you right click on the ffdshow dxva video icon, is the subtitle option checked?

Yeah, here is a screenshot in MPC. I tried switching through each subtitle stream and no luck. Must be gremlins in my PC

[SamuriHL]

AHA! I know what the issue is. Go back into ffdshow dxva video settings and under the hardware acceleration section, turn on post processing.

Brilliant, it is working now

That's my fault. I forgot that setting. I wish ffdshow had an "enable all crap to get MKV + subs + dxva + bitstreaming working" button.

LOL, the "enable crap" feature!!!

Well, doesn't it make sense? We know what options should be set by default to make everything work. I want one button to set it all. I don't care what they call it. LOL! And yes, I know, I know...I could just export the settings. I'm lazy!

[MikeEby]

Are you guys trying MKVMerge from the CL or the GUI?....I'm wondering if only the GUI doesn't support PGS Subs.

Also on files made with MakeMKV can you set the subs default to off but then play forced subs automatically if they are present?...These are things I've struggled with on my GUI when I convert the subs to .IDX.

In most cases I only want to see forced subs by default although it would be nice to have non-forced present in the file. I also don't want to be bothered to turn them off. I also don't want to turn them on if only forced subs are present...Does that make sense?
