ffdshow tryouts project: Discussion & Development

[SamuriHL]

Thanks, Vladd, for testing that. At least you're getting similar results to what I'm seeing. :) Not that it's good, but, at least it's consistent and not something I'm doing wrong.

[whurlston]

One more question vladd:

At this stage of graph:

FileSource(asynch) > Arcsoft MPEG Demux > ffdshow audio decoder

What do you read on Properties Page of ffdShow ?(under "out")

Thx. But do you see the same info before (without) linking the renderer?

Yup. GraphStudio just doesn't print the info in the report if it's not linked.

[SamuriHL]

I just realized you guys are using GraphStudio not GraphEdit. Neat. I hadn't seen this before but that's a very impressive piece of software. Will be learning more about it. I know the very basics of GraphEdit but this seems to expand upon that functionality. Nice.

Yes this was the answer i expected.

IMO ffdshow makes bitstream but no renderer is available yet to render it.
When you link ffdshow to default renderer, ffdshow drops to PCM mode i suppose.

[SamuriHL]

Well, hopefully they have some success on a WASAPI audio renderer. That would rock.

[rica]

Hopefully James; everything is ready for James indeed.

[SamuriHL]

We'll see what happens.

[whurlston]

When you link ffdshow to default renderer, ffdshow drops to PCM mode i suppose.Yup, that's exactly what's happening.

[rica]

Or another option is MPC-HC Audio Renderer with the contribution of albain:

[Gerbrand]

Hello,

I do not know if this is the right place to post this, but I posted this issue over at avs and did not get an answer.

My issue is the following:

When playing a Blu-ray with LPCM (e.g. Casino Royale, Pirates of the Caribbean) through the following graph

MPC-HC internal splitter -> ffdshow audio -> reclock (encode to AC3) -> SPDIF

I am not getting sound from one of the two surround channels (somethings left and sometimes right).

I have narrowed the problem down to ffdshow audio (I am using build 3069): e.g. if I use MPC-HC's internal LPCM decoder it works fine. Also, if I use ffdshow audio's "swap channel" function I can swap the mute channel from left to right surround.

Ffdshow, reclock and my receiver all report 6 channels present.

Any idea what could be causing this? If I select the Dolby Digital track all works fine, DTS-HD also works (although I only get the core).

Thanks for helping out (or directing me to the right thread),

Gerbrand

[rica]

Sorry if i misunderstood:
You get LPCM (decoded as is via ffdshow) over what?
You get ac3 (pass-through) over SPDIF, it is fine?
And what are you trying to do: re-encode LPCM to ac3 and sent it to receiver?

[Gerbrand]

Sorry if I have not been clear enough.

What I try to do is the following: decode the LPCM using FFDshow, then reencode to AC3 using Reclock and output over SPDIF.

I only get this issue when I use ffdshow to decode the LPCM. If I use another decoder, it works fine. Also if I use another format (e.g. DTS) it works. I have tried it without Reclock (use FFDshow for the reencode) and I still get the same issue. So to me it seems it must definitely be ffdshow.

Any ideas?

Gerbrand

[rica]

Have no idea but i keep going not to understand why you are trying to downsample an LPCM of a Blu?
You don't have analog outputs or an HDMI output (like 4*** series has)?

Anyway, give it a go with this:


FFDShow TrueHD bitstream outputs Reclock IEEE Float mediatype (http://damienbt.free.fr/ffdshow_rev3089_20090927_dbt_beta6_reclockIEEEFloat.zip)

[rica]

BTW, MSDN document:

http://msdn.microsoft.com/en-us/library/dd316761%28VS.85%29.aspx

Seems MS only agreed with Dolby Laboratories.
DTS-HD support seems to be missing in WAVEFORMATEXTENSIBLE_IEC61937 as far as i understood?

[SamuriHL]

Um, what the? That seems rather ungood.

[whurlston]

Seems MS only agreed with Dolby Laboratories.
DTS_HD support is missing in WAVEFORMATEXTENSIBLE_IEC61937 as far as i understand.

It's not missing from the WAVEFORMATEXTENSIBLE_IEC61937, as mentioned in that document.

Support for DTS-HD compressed streams is missing from the Windows 7 HD Audio class driver: http://msdn.microsoft.com/en-us/library/dd567920.aspx

[rica]

Correct, thanks. :)

Note Not all the available formats are supported by the Windows 7 HD audio class driver. The formats supported by Windows 7 are indicated in the tables with an asterisk (*).



http://img3.imageshack.us/img3/2258/97367725.th.png (http://img3.imageshack.us/i/97367725.png/)

No asterisk on DTS-HD?

[Gerbrand]

My receiver does not have HDMI in and the analogue outs of my motherboard are not so good. I try to use the downsampled LPCM, because sometimes a different mix (more dynamics) is used for the HD audio formats than for the regular dolby digital tracks.

Anyway, I will give the link a try.

Gerbrand

FFDShow has the ability to encode to AC3 : just check the AC3 box in the output section and see if it solves the problem

Also, provide the information about what is outputted by ffdshow : sample rate (48khz or more), number of channels, sample size (16 bits, 24 bits, ...)
And compare this information when you don't use ffdshow.


To bitstream testers : status summary
Everything you can see from the output of ffdshow is fully on our control. I can provide AC3,PCM mediatype or anyone else, use the windows 7 IEC structure or not...
So far I have tried several combinations with no success :

AC3 SPDIF structure as for DD/DTS (beta 8, but IEC implementation was not correct, maybe a new test should be done) => Link to new build with AC3 media type (http://www.mediafire.com/?sharekey=05fb19b4b2e4495ee7c82ed4b8f0c380e04e75f6e8ebb871)
Settings : IEC unchecked, use with Reclock. And in Reclock settings, uncheck "Enable audio timestretching" to avoid that reclock messes up with the data
PCM output but with the right description of the compressed data (beta 9)
PCM output with the new IEC structure (for windows 7) (not compatible with reclock, to be used on windows 7 and a compatible audio driver) (beta 9 + IEC checked)
Same IEC structure but with the real compressed media type instead (beta 10 + IEC checked)
The real compressed media type without IEC structure (beta 10)


Next steps :

Work with MPC-HC team to bring the necessary modifications to the audio renderer (wasapi)
Get some answers from Microsoft about the IEC implementation, from AMD about the bitstream implementation


About DTS-HD, this is the next step, the media type is there, there is just a lack of details but this is doable

[Inventive Software]

If ffdshow doesn't load then it doesn't support the format.

And before you ask. If you want it to get added follow the following steps:
1) Open a feature request at the SourceForge project page
2) Include a sample file
3) Wait*

* This step may take forever. Certainly if it is a wma3 variant that is not yet supported by FFmpeg.

WMA Pro support recently got added to FFmpeg. I posted this twice already but it seems to have gotten buried in the bitstreaming discussion.

thanks for your reply.

But why is it then that ffdshow does not load (and of course not decode) the audio? I ve selected all the codecs to be sure but it just does not work.

[clsid]

@Inventive Software
I already knew that as I read the FFmpeg SVN log almost daily. It changes nothing, as there currently does not seem to be anyone with the time and willingness to add it to ffdshow. There are simply too few developers working on ffdshow at this moment.

@THX-UltraII
ffdshow does not include everything that FFmpeg does, only a subset.

So for my 1400gb .mwv material ffdshow is just not usable?!

Yes, this is annoying

What's required to get it working? I thought it was a case of plugging in the code, changing certain links to it, and compiling and away ya go. Yes I know in real life it's never as simple as that. ;)

No, you must :
1/ declare a new decoder in FFDShow and add it to the interface (ffdshow.rc) in the codec section
2/ detect the input format according to the media type and assign the new decoder

"The renderer accepted the change of media type but failed with reconnection"

That's with ReClock enabled, IEC unchecked, with the new AC3 build.

That's the debug info before I clicked ok on the dialog I quoted previously and MPC-HC crashed. Hope this helps.

[clsid]

So for my 1400gb .wmv material ffdshow is just not usable?!Let ffdshow process uncompressed audio and you can post-process any audio format for which you have a third party decoder installed.

But if it is such a big deal for you, nobody is stopping you from adding it yourself and submitting a patch.

[whurlston]

"The renderer accepted the change of media type but failed with reconnection"

That's with ReClock enabled, IEC unchecked, with the new AC3 build.

I get the same results.

[albain]

Okay, I didn't expect a miracle... :-)

I am waiting for a feedback of Casimir666 from MPC-HC team.
Otherwise I will try to implement WASAPI by myself inside MPC-HC. I have already done a little about it on FFDShow for multichannel devices (an unstable feature though :-))

Stay tuned !

[SamuriHL]

Awesome. We'll be here when you need more stuff tested. :) I have all the builds cached so if you need me to go back to b10 or whatever when the audio renderer is ready I'll be able to do that.

[Emilot]

we must pay a respect to all of you for your time and passion....

Thank you for your awesome job guys.....:thanks:

It was worth a shot! :D We appreciate all the work you've done so far.

[mrcorbo]

It was worth a shot! :D We appreciate all the work you've done so far.

Indeed. Thanks to albain and testers both. I think an open-source WASAPI/exclusive audio renderer and open-source HD audio bitstreaming code are both good projects for the community at large whether they come together or separately. I've been testing with my 4870 on Win7 X64, but haven't posted results since I really haven't had anything to add to what has already been posted. Once you get something working, though, I'll be happy to try to break it ;).

[Gerbrand]

FFDShow has the ability to encode to AC3 : just check the AC3 box in the output section and see if it solves the problem


I did that and reclock reports it receives an AC3 stream, but still the right surround channel stays mute.


Also, provide the information about what is outputted by ffdshow : sample rate (48khz or more), number of channels, sample size (16 bits, 24 bits, ...)
And compare this information when you don't use ffdshow.


In both cases Reclock reports 48000 Hz, 6 channel(s), PCM IEEE Float (which it should).

As shown below if I do not use ffdshow, reclock sees the same input format as when I do use ffdshow. So both MPC-HC's internal LPCM decoder and ffdshow output 6 channels, but for some reason the 6th channel of ffdshow is empty. Any idea what could be going on?

Thanks,

Gerbrand

Do you have a sample to provide ?

So to sum up : you want to play a HD LPCM (so uncompressed) track from a bluray and output it on your SPDIF output.
As SPDIF does not support HD LPCM, you have to convert it to AC3 : you can use FFDShow or Reclock for that
Still, did you enable the mixer filter inside ffdshow to downmix from 7.1 to 5.1 ? Is it 5.1 or 7.1 ?
Indeed AC3 is limited to 6 channels

I applied a fix on LPCM channels mapping on revision 3050.
Can you try a revision 3049 or less and report if the problem is still there ?
Here is a link (http://www.xvidvideo.ru/content/category/1/4/5/) to find older (and newer too) revisions

There may be a different channels mapping between HD LPCM and SD LPCM (5.1).

Also it would be great that you test both LPCM formats : 5.1 and 7.1 to confirm what is not working in each case

HAHAHA. If you've seen my thread on Slysoft you would know that there is no release date info at all. I have no insider knowledge or anything like that. Unfortunately, we simply have no idea. I can assuredly tell you it's not days. Probably not weeks, either. The "official" response Slysoft always gives on release dates is "February". :D

[Gerbrand]

I will try to figure out how to extract a sample.

This is correct.


Still, did you enable the mixer filter inside ffdshow to downmix from 7.1 to 5.1 ? Is it 5.1 or 7.1 ?

The original LPCM is 5.1 (as can be seen from the input of ffdshow that I provided above). I did not enable the mixer, I will try if it helps. However, when I used the swap channel option (which is sort of the same) I could make the mute channel swap.


Can you try a revision 3049 or less and report if the problem is still there ?


I think I used an earlier revision before with the same result, but I will try again.


Also it would be great that you test both LPCM formats : 5.1 and 7.1 to confirm what is not working in each case

I do not know if I have 7.1 LPCM, but I will search my collection.

Thanks for the help so far,

Gerbrand

[albain]

I reviewed your post and the revision you used is post-3049

Ok, there may be a problem with LPCM 5.1 channel remapping, but if you can confirm that it works with 3049, the fix is easy otherwise I will need a sample

BUG: ffdshow will not play this WMV9 video without the picture looking extremely blocky and just plain wrong, with libavcodec or the wmv9 decoder. http://www.megaupload.com/?d=4UQ8SHDP

Playback is absolutely fine in Windows Media Player. :confused:

Only upon disabling the WMV3 decoder in ffdshow does it play correctly, and that's only because it goes back to MS's decoder.

Using latest ffdshow from clsid's generic builds.
