ffdshow tryouts project: Discussion & Development

[Emilot]

Hi albain, with the newest audio renderer and ffdshow, i get these:

No sound at all:

Noise/distortion only:

http://img692.imageshack.us/img692/9439/loudysound.th.png (http://img692.imageshack.us/i/loudysound.png/)

Trials were made with Ati 5770 and Denon 1910 using latest Ati drivers or with Realtek R235.

Thanks.

BTW MPC mpeg source doesn't want to connect to ffdshow but ACMWrapper so the chain would be: MPC mpeg source > ACM Wrapper > MPC Audio Renderer. (with/without ffdShow debugging enabled)

Another thing; both PDVD9 and TMT3 gives DD core (false; lets say basic ac3) audio when i use the same source file.

I think you should check 24bit and 32bit, at ffdshow output....or just try it....

thx; already given it a go.

Hi Albain,

Just double checking... is the latest beta intended to bring bitstreaming to the Xonar card only (for the time being), or should it also bring bitstreaming to the ATi 5xxx and GeForce 9300/9400 HDMI Audio as well at this stage?

Just checking so the non-Xonar guys know whether to stand down at the moment or keep testing.

I'm cool either way as i have both a Xonar and GeForce 9300! :devil:

Thanks

Hey Guys,
neb1236 has brought to my attention that I have forgot to implement one of the previous OSD features:
in the past, there was an ability to auto-hide the OSD after a predefined number of frames.

I have now implemented this feature:

http://iknowu.net/files/public/ffdshow/PresetOSD/AutoHideOSD.png

patch:
http://iknowu.net/files/public/ffdshow/PresetOSD/3130-AutoHideOSD.patch

build: (use it for OSD testing only, GCC dlls are not up to date)
http://iknowu.net/files/public/ffdshow/PresetOSD/ffdshow_rev3130_20091110-AutoHideOSD.exe

[ryrynz]

Feature Request:

I would love to see a "on directory match" preset for configuration loading.

Finally,

here is the last FFDSHow HD bistream beta (http://www.mediafire.com/file/mymzgynumyn/FFDShow_HDbitstream_beta31_pack.zip)

Now the behaviour is "iso-TMT".

It is a pack that contains the MPC mpeg splitter updated to passthrough DTS HD streams (you have to register it)
There is also an updated version of the MPC renderer

Thanks for your feedbacks

is this the version also for the ATI 4xxx-users so bitstreaming works?

Hi :)

Great , i want to test it quickly :)
Big Thx :)

Not yet

[albain]

A few precisions on changes :

Improvements of the codec initialization : before FFDShow always published an uncompressed type in output then switched to SPDIF/bitstream. This could cause problems, especially with wasapi renderer that (for an unknown reason) refuses the multichannel PCM streams (which explains the recent failing tests)
TrueHD : the most complicated implementation, because silenses have to be inserted at a regular rate (but the rate depends on the size of the MLP frame). I applied a 1/12 ratio (close to TMT but I didn't figure out the exact rule). I hope that this is correct and won't bring audio gaps
DTS HD : implementation is correct (equal to TMT's)
EAC3 : done but I didn't have any EAC3 logs (I have to supply a sample to Sebastii)
Maybe it will work with the arcsoft audio renderer (as FFDShow tries different types including arcsoft's)

5*** series; should i try?

OK, you say it's my turn :thanks:

I've got a 7.1 sample if you need it.

[Sebastiii]

Hi,

So MPC connect to ffdshow for me :)
But no bitstream for now is hard because your great Work.
Strange think is that i register mpegsplitter but i can't see it in filter.
Strange think too, if i use DTSHD sample when i play ffdshow in output in output DTS option is not check.

So this this the log :)

Log Beta31 and MPC renderer. (http://sebinternet.free.fr/LOG-Beta31.zip)

Thank :)
And yes if someone can find E-AC3 Bitstream sample for i can log it with TMT :)

Seb.

Hi, yes it would be great :)

I was about to post the same issue.
BTW if i build a graph with arcsoft mpeg demux, ffdshow never selects MPC audio renderer but default direct sound device.
(Tried with albain's THD sample.)

EAC3 : done but I didn't have any EAC3 logs (I have to supply a sample to Sebastii)

http://forum.doom9.org/showthread.php?p=1342354#post1342354

Didn't I put an eac3 log in my post? The DDPlus one?

Oh, and as for the mpeg splitter - register it then browse with the add external filters option to the .ax file to make it show up in MPC. Won't be able to test this until at least tomorrow night :(

Thanks again albain.

Sorry but it seems to me impossible unless you see it in the filters list. Negative in advance...

[rica]

btw, albain please have an ati card asap:)
I told i bet albain would fix bitstream before Cyberlink. :)

[SamuriHL]

Yikes I missed a lot today. Sorry had lots going on today. I will try to look at this maybe later tonight if not tomorrow for sure. Nice work!

Hi Seb,

I have seen your logs and unlike SamuriHL who also has a 5xxx card the TrueHD media type is refused by the renderer.

Could you guys exchange together on this, it must be a driver issue.

I must admit that I am relieved because it is just not normal that you get no sound

About DTS HD, indeed there is a problem with MPC splitter that I built, because it has no filter category : here is the new one (http://www.mediafire.com/file/nnztnyj2mty/MpegSplitter.ax)
However, as for TrueHD your driver will refuse the mediatype, but I think it was the same for SamuriHL too

About EAC3, the sample we already have is a M2TS file but I have troubles to make a bluray structure with tsmuxer (it does not detect the audio stream). If someone has an idea or a BR sample with DD Plus...

About EAC3, the sample we already have is a M2TS file but I have troubles to make a bluray structure with tsmuxer (it does not detect the audio stream). If someone has an idea or a BR sample with DD Plus...


Only one I know if is Transformers with a DD+ commentary track. Sample available here (http://stfcc.org/misc/transformers.sample.m2ts). The MPC-HC splitter doesn't see the E-AC3 track though.

[albain]

I found why DTS-HD is not accepted, the sample rate I pushed was not correct. It should be now with this new pack (http://www.mediafire.com/file/thtinrwcnwz/FFDShow_HDbitstream_beta32_pack.zip) (FFDShow updated, MPC splitter updated, same MPC audio renderer)

Also, I know also why the PCM types are refused by the renderer : this is because when FFDShow switches back to PCM mode when the HD bitstream format is refused, it will uncompress the TrueHD track and the PCM stream runs at 192Khz, which is too high.
So you have to enable the resample filter to downsample to 96 or 48khz and it will be accepted.

Or else there is LPCM format but I am not sure that HDMI 1.3 is able to transport more than 96khz uncompressed data.

@Snowknight26 : I will address this problem later to see how to detect the track (maybe haali is able to see it, not gabest's)

[madshi]

Or else there is LPCM format but I am not sure that HDMI 1.3 is able to transport more than 96khz uncompressed data.
It would be great if you could support LPCM bitstream, too. HDMI 1.0 already supported 7.1 192khz.

"The Sound of High Definition" Blu-Ray Had a few,
I kept "00026.m2ts" which is DD+ 7.1 Channe Test,
I'll try to upload it tonight, if I won't get arrested for sneaking into Nouriel Roubini's lecture this evening.

[albain]

The problem is to transform it to a Bluray structure because TMT won't bitstream with media files, only blurays (disc or folder structure).

Tsmuxer does this conversion (m2ts to BR structure) but does not recognize the EAC3 track.
Maybe there is another tool

Concerning LPCM, ffdshow already supports it, but I don't know when it is used. I *just* have to use the existing support when the input stream is HD bistream

Any 5xxx owner awake ? :thanks:

Hi Damien,

Great news, so go to new test :)
My log for version 31 was made with Xonar Driver, if i use ATI HDMI, ffdshow show Bitstream when i move mouse on it (i haven't made log yet) but no sound.

I'll make test tonight, i'm at work, i can make test via TSE, but not on ATI HDMI card and i can't see if AVR show up the light with Xonar lol.

Seb :)

Thx :)

[albain]

Seb, you don't have a webcam starring on your receiver lights ;-) ??

From your logs, indeed the xonar will refuse the official truehd type and ffdshow will try others (including arcsoft), but I think there is a bug on that part because the MPC renderer don't see the updated types that are tried (the official one is still sent). I will check on this.

So a 5xxx is the way to go for now

[Sebastiii]

hi lol :)

I'll make test with ATI :)
I'll post log for DD+ in couple of minutes i think :)
Seb. :)

Vla le Log :)
Log EAC3 Bitstream (http://sebinternet.free.fr/bitstreamEAC3.zip)
Seb.

[albain]

Thanks, I have now brought support to EAC3 and fixed DTS-HD (there was another bug again)

Here is the FFDShow build (http://www.mediafire.com/file/mymegtnmytj/ffdshow_rev3128_20091112_dbt_bitstream_beta33.zip)

Those 2 formats are easier to bitstream than TrueHD.

Now : 1 FFDShow bitstream frame = 1 TMT frame for DTS-HD and EAC3, and for TrueHD silences are just not equally spaced

If this still does not work then the problem comes from the MPC audio renderer

[SamuriHL]

I'm up now and as soon as I get the handshaking to play nice I'll give it a shot. Gotta leave for a while in a few minutes but I'll be back later.

[SamuriHL]

Sorry my friend, but, DTS-HD MA is not working for me with the 5870. I get DTS and it detects it completely wrong when mousing over the tray icon.

DTS-HD MA: http://pastebin.com/pastebin.php?dl=d27c5448

Lights are on but no one's home. No audio. But at least there's some lights. :D

[liquidskin76]

@Albain,

Are these latest beta's aimed at getting HD bitstreaming working (at this stage of development) for the ATI 5xxx cards only, or are you aiming at the Xonar card as well?

I'm a little lost at where we are in the grand scheme of things!

Thanks

[liquidskin76]

@samuriHL,

Are you testing on your ATI 5xxx or Xonar, or both?

Thanks

[SamuriHL]

5870. I'm not testing it with the Xonar at all.

[albain]

Ok, the TrueHD log "sounds" good

Concerning the DTS-HD log, indeed you only get DTS because you don't have the last version of the MPC splitter (which strips off HD blocks) Please use this one (http://www.mediafire.com/file/nnztnyj2mty/MpegSplitter.ax) : register it and use graphstudio with "MPC - Mpeg source" filter.

About the Xonar, it should work with it as arcsoft media types are sent to the driver but Seb tried and didn't any good results.

So to summarize :
- the latest build claims to support HD bitstreaming on radeon 5xxx
- the xonar is supposed to be supported but tests are not good so far (but further tests are needed)
- the 4xxx series is not supported yet

That's odd. I reregistered them this morning with the latest versions. Anyway, I'll try again.

[SamuriHL]

Yea, no. Doing what you suggest hangs GraphStudio, I get no audio at all, and I have to kill the process.

[SamuriHL]

Managed to log what I could for that. This is a DTS-HD MA track run through graphstudio.

http://pastebin.com/pastebin.php?dl=d14998238

[albain]

The DTS HD format is accepted by the renderer

This is weird that graphstudio hangs...

[liquidskin76]

I've been doing some early test on my Xonar however i haven't had chance to test on my av receiver yet so i don't know the true outcome audio wise.

Doing just visual test on graphstudio i'm finding the TrueHD and DTS-HD MA files are playing ok. I'll let you what ffdshow is reporting the output as later (i'll do some test later tonight on my av reciever).

One thing i did notice is that if i have video decoding disabled in ffdshow, and use a decoder like CoreAVC, the audio renderer switches to the default directshow renderer in graphstudio. You have to manual switch renderer, whereas if you have video decoding enabled in ffdshow, the MPC audio renderer is automatically used.

One to note for later maybe?

Thanks

[SamuriHL]

The DTS HD format is accepted by the renderer

This is weird that graphstudio hangs...

Yea I don't get it. And it doesn't work in MPC-HC either. I guess I can try a different movie but I doubt it'll make any difference.

[SamuriHL]

So MPC-HC gives me just DTS (and the tray icon shows it as DD...yeaaaaaa). I tried another DTS-HD MA source in graphstudio and I get the same result. The tray icon shows DTS-HD and that it's bitstreaming but the receiver does nothing and the file hangs graphstudio. I'm sure I have the latest versions of everything you've given us so I don't know.
