ffdshow tryouts project: Discussion & Development

[mark0077]

Hi all. I have a few hundred mobile phone videos in mp4 format that wont play using ffdshow libavcodec mpeg4 decoder. Using xvid ffdshow decoder, or mpc-hc's own decoder it works fine.

Can anyone confirm, or shall I give a sample if anyone is interested in looking into it?

[clsid]

A sample would be useful.

[mark0077]

Thanks, here is a 6mb sample. If I use ffdshow libavcodec mpeg4 decoder, the sound plays, the first frame of the video shows but no more. I notice if I move the window around a little bit, the frames start to show. Its like the frames are being decoded properly just not getting through to the renderer or something like that, until I do a window move, pause / unpause.

Hey guys been experimenting with some h.264 interlaced video and it really brought my 3.0 Core 2 duo to its knees. Is there any way to have ffdshow NOT deinterlace, and output interlaced so my TV can handle it? For the life of me I can't seem to find the option, and google has been useless.

[Andy o]

I'm not sure now if ffdshow is deinterlacing. I just assumed it did because of the huge CPU resources it is required for 1080i H.264. Maybe it's the renderer (using MPC-HC 1330).

[jruggle]

Hi. Thanks for your work! But it seems there is still a bit of distortion. I noticed it with my previous sample but it was hard to tell. Now I found another one (http://www.mediafire.com/file/mtmhtyzmmm2/sample2.AC3). I can hear some distortion at 5-6 second, which shouldn't be there.
Latest ffmpeg revision tested 20467 - distortion
As before, works fine with 20024 revision (closest revision to 20036-20055 that I have...).
No errors reported this time.
fixed in r20473. This was a different bug.

BTW, any idea who I could ask to see 32float DTS please? I tried to sign up on the ffmpeg user mailing list, but never received any confirmation email...I tried w/ 2 different email providers.

The problem only seems to occur with EVR Custom Presenter.
It also only occurs when the output colorspace is NOT equal to YV12. If I force YV12 (uncheck all others), then it plays fine.

I don't know why this happens or how to solve it. But maybe anyone else knows. Maybe one of the MPC devs.

The funny thing is that it's working fine for me on an old PC using a very old version of ffdshow that I never bothered to update. It's playing fine with YUY2 and EVR custom output:

http://img260.imageshack.us/img260/4161/strange3.png

There is some kind of little 'hop' at the start but after that it's playing fine. Also the file is using variable frame rate mode, maybe that's the reason of the troubles ?

Frame rate mode : Variable
Frame rate : 29.212 fps
Minimum frame rate : 7.442 fps
Maximum frame rate : 31.120 fps

Hi,

new FFDShow HD bitstream beta build (http://www.mediafire.com/file/jvuymtyqnzz/ffdshow_rev3128_20091108_dbt_bitstream_beta29.zip)


This new build adds the following feature : testing several subtypes if the official one fails. This should bring bitstream support to the xonar.

I didn't change the bitstream code yet

Cool, time to dig out my Xonar! Was started to get worried that i might not be able to bitstream with my GeForce 9300 HDMi audio!

When you say bitstream, are you hoping for DTS-HD as well?

Hi,

Could you explain what you use for bitstream :) ?
If i use MPC-HC ffdshow Audio don't start.
If i make GRF with graphstudio, i can play but no sound and no light comes on.
Did we use MPC Audio Wasapi Renderer (i think yes lol).

So this is the log and Screenshot of my Graphstudio :

And


Log Debugview release Beta29 (http://sebinternet.free.fr/DTSHDffdshow29.zip)

Thanks for all :)
Seb.

[Skinleech]

I will try it in a while also.

Thank you yet again!

[Skinleech]

Ok, so using the latest ffdshow bitstream pack & MPC Audio renderer, I get no sound on anything except regular ac3 which is fine.

The files don't play at all and the debugview logs keep going as long as MPC is active.

Will pastebin the logs for each soon.

[SamuriHL]

Same result I got with the last version.

[albain]

For this one the goal is just to make the connection accepted by the audio driver for the xonar (not for 4xxx series yet).
There is a new "try mode" that will for bitstream formats try several media types. Maybe this will also make DTS-HD work

You won't get more sound that with sebastii tests but I just need the logs (debugview) to confirm or not the connection.

What's next : I have to analyze sebastii's last logs, and reproduce as much the bitstream, then the work will be finished on FFDShow's side.

Then the last part : the MPC audio renderer implementation, which must not be correct (buffer size, buffer feeding) otherwise you would get some sound.

Be patient, this takes a lot of time, and most of us have a job in parallel (besides I spent some time lately on Media Control)

[SamuriHL]

No problem on my side, albain, with the patience thing. You've put a remarkable amount of time and effort into this and it's very appreciated! Take your time. I'm sure it'll come. I'm hoping my work schedule slows down after tomorrow so I can do more testing. It's been crazy the past couple weeks. :( So, I fully get the real world stuff getting in the way concept. I hope others understand, as well.

[albain]

Oh my....

@Sebastii : the audio renderer you got is buggy.

Please use this one (http://www.mediafire.com/file/y3f5yndhgmz/MpcAudioRendererFilter.ax)

@Sebastii : can you also test a TrueHD stream with this audio renderer (the buffer has been resized)

Thanks !

You should see the light again on your receiver

[Skinleech]

Albain, I have no issue with being patient at all either, I'm very grateful for your time and effort and will continue to help in any way I can. I've seen it exactly as you describe - an attempt to connect several times. Here are the logs for you:

Sorry, but the mpc audio renderer was a debug version that only wrote to a file, which explains the "Setfilename ok" trace in it.

This explains why you guys don't get any light and sound. Sorry for that

Please use the link in previous post

[tetsuo55]

May i suggest donations of cash or hardware to albain?
This would speedup this research a 100fold

the Onkyo TX-SR607 is about 400 euros and supports all the formats we are testing

Hdmi cable is about 10-20 euros

5xx0 card is about 120 euros
Xonar is about 130 euros

DDplus: http://pastebin.com/d6399a732 - played in PCM
AC3: http://pastebin.com/f6ecf0699 - played video, no audio. Likely a setup issue, as changiong from Asus Speakers to Asus Spdif device in Windows audio mixer gave the following:

Unfortunately, even the top-of-the-line receivers from Onkyo (and Denon) suffer from HDMI implementation issues. You should take a look at AVSforum where countless HTPC users report issues with various combinations of GPU/IGP + receiver. Some work, some don't.

The only route, and this is what Intel, nVidia and ATI engineers are doing, is to purchase and test several different receivers.

In any case, the Denon 1610 (caveat from first paragraph still applies) could do the job and can be had for as low as 315 EUR. A quality HDMI cable can be purchased from Amazon for about 5 EUR.

Thanks :-) but I already have an okyo 606, and I wait that AMD releases a passive 5xxx card. I hope that it will be released soon

@Skinleech : thanks, it is better with the new renderer, but your logs seem incomplete. Can you check ?

Hi :)

Like SamuriHL said no pb and thx you for your patience :)
So i think the 2 link are the same.
I wrote more clearly i think
In my setup, In graphstudio i can't connect ffdshow Audio to the New MPC Renderer directly.
When i connect it, WMAudio Encodeur to WMAudio DECODEUR appear between ffdshow Audio and MPC Renderer.
I must be something wrong lol.

If i put directly Asus Digital renderer bitstream don't work for DTS-HD and TRUE-HD.
For DTS-HD : Asus Digital renderer -> Sound but no DD
For DTS-HD : Asus Speaker renderer -> Sound in PCM

For TRUE-HD (96Khz) standard TRUE-HD : Asus Digital renderer -> don't want to play Sound and Video
For TRUE-HD (96Khz) standard TRUE-HD : Asus Speaker renderer -> don't want to play Sound and Video

Big thx :)
Seb.

Thank you Seb

Indeed the links were the same, here is the other link (http://www.mediafire.com/file/wmimmyizunn/MpcAudioRendererFilter_bufferTrueHD.zip)

Could you post the debugview of graphstudio connection ?

If the direct connection is refused by the renderer, the media types have been refused and it should appear in FFDShow debugview

Merci !

[Sebastiii]

Hi :)

Yep sorry this is the log :) Renderer N°1=MPC Renderer And Renderer N°2=MPC TrueHD Buffer (http://sebinternet.free.fr/Debugrenderer1et2.zip)

Thx you :)

[Skinleech]

Hi Albain.

I'll repost the logs when I get in from work - but not sure what was missing? I copied/pasted directly from the saved dbgview logs into pastebin.

If you need me to re-run them just say and I'll get on it.

Thanks!

[albain]

Ok thank you guys

Here is a new beta build (http://www.mediafire.com/file/fm2z5mzmozj/ffdshow_rev3128_20091109_dbt_bitstream_beta30.zip)

The DTS-HD implementation is now correct : I reproducted EXACTLY the bitstream sent by TMT

Concerning TrueHD, this may be more complicated because frames are spaced differently but we may have sound

In both cases I added the missing frames in the header

[THX-UltraII]

Ok thank you guys

Seb,

have you disabled the IEC structure in ffdshow output section ?

I can see that the AC3 media types are automatically transformed by FFDShow to PCM (i.e decoding). Didn't you check AC3 bitstream ?

[Keiyakusha]

Does wavpack decoder in ffdshow supports only lossless streams?

Anyway, I can't decode audio in this (http://www.mediafire.com/file/z2ybzvbhzzt/sample.mkv) sample. Works fine with official wavpack DS decoder.

EDIT: by the way, this is 5.1 wavpack stream. mediainfo shows wrong channel info...

[clsid]

The WavPack decoder in ffdshow has limited capabilities. It is recommended to use the official WavPack filters.

[albain]

Ok I don't know why you get this, I will digg this around

Otherwise, I think I understood why the TrueHD bitstream did not work.

There is a last step for perform. I try to figure this out with Madshi and this should be the last (I hope)

Otherwise, DTS-HD is okay from my point of view. It should work once the connection works again with the MPC audio renderer

[Skinleech]

Here are my Beta 30 logs. Hopefully what you need, these are the full logs as saved from DebugView.

I know, you don't have FFDShow debugging enabled :
please open regedit, goto HKEY_CURRENT_USER\Software\GNU\ffdshow and create a DWORD value named "allowDPRINTF" with value 1. It should be better

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

No sound at all:

http://img69.imageshack.us/img69/2863/nosound.th.png (http://img69.imageshack.us/i/nosound.png/)


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.
