ffdshow tryouts project: Discussion & Development

[Leak]

Perhaps you could create a modified copy of that DVD for Haruhiko (and Leak) for testing purposes? With for example DVDShrink it is possible to replace all videos with a still image and keep the original menus. That should result in a very small ISO.
I've found that VOBBlanker does an even better job at that; it could be harder to use, though.

np: Moonbeam - You Can Hear Them (100)

Here is a RAR containing the menu (ended up being 107mb) and the parts of the clip that I thuoght were necessary. Total 219mb

Hope its not too big.

So my test for crashing is, use mpc-hc decoder. Start movie, when menu appears go into options, try and hover over the audio options. You will see hovering over options doesn't show highlights.
http://www.megaupload.com/?d=V2XYOUFA

Slowness of menu text before each song smoothness is not visible in this test as they are semi-removed but I can make another clip containing these if is not reproducable using other tests. This one shows the problem when using decoders outside of ffdshowl.

I cannot ever get through the following sequence without frame drops / glithces / freezes

Start Queen DVD -> Go to options menu -> Select 5.1 DTS -> go to main menu -> Start movie / songs

[haruhiko_yamagata]

I can reproduce the unclickable 'option' menu. The stream has bogus AR, rev 2800 fixes the problem.
I don't have the slowdown problem.

Unfortunately all of my original problems still stand with this build, with mpc-hc beliyaals build using evr-custom presentation.

Try disabling ffdshow mpeg2 decoder and navigate into "Options" in that DVD Shrink I posted. I have never been able to move the mouse up and down through the items and have the highlights appear in this config. No hardware or operating system or version of ffdshow has ever let me do this. The highlights don't appear as I move the mouse up and down through the items.

[haruhiko_yamagata]

Can I merge the subtitle branch?
If nobody can find any regressions, I'll commit this.

Please update to the latest MPC-HC. EVR Custom Pres. (on Vista) isn't very stable for me.

[mark0077]

Please update to the latest MPC-HC. EVR Custom Pres. (on Vista) isn't very stable for me.

I will try different renderers later tonight to see if the problem is related to that. I am using the latest build from
http://forum.doom9.org/showthread.php?t=145203 but the problem has been there for.... well for as long as I can remember. I will update you when I try different renderers later, maybe the problem is evr-cp related.

[tetsuo55]

Although things should work on all renders, focus seems to be moving to EVR-CP.
Logical since that render works on XP and up and is the most advanced.

[haruhiko_yamagata]

I can reproduce now, perhaps I have missed something in the combination of the settings.

// EDIT
Debug build is OK, release build is not.

[mark0077]

Great stuff, thanks alot for testing. Once that lack of highlight with non ffdshow mpeg2 decoders is sorted ;) then I have almost no problems. I will check again tonight to see if I can provide a smaller sample to reproduce the "slow fade" problem with ffdshow libmpeg2 aswell as garbled picture quality with ffdshow libavcodec. Maybe these also are evr-custom presentation related.

Thanks

EDIT: Sorry, the latest build you sent up doesn't show the slow fade problem anymore... might have been something on my end I am not sure.

The only two problems remaining are
1) No highlights when using non ffdshow decoder - You have been able to reproduce ;)
2) Garbled decoding using ffdshow libavcodec mpeg2 decoder - I can reproduce with all of the latest builds but only in this Queen DVD. The video I uploaded will demonstrate the problem when using libavcodec for mpeg2. When you cllck play, the garbled output begins. This scene is interlaced and I have noticed a problem with this DVD in the past with libavcodec as it usually detects the fields the wrong way around (other decoders don't show this swapped fields problem). In the past using libavcodec I need to manually swap fields for this DVD. Now this problem arises instead with garbled output. Try the shrink I uploaded recently which will show you the problem.

Hello,

I would like to submit an issue with clsid's installer. It's related to another old issue that I submitted in august 2007:
http://forum.doom9.org/showpost.php?p=1034129

There are two sub-issues, and together they cause some trouble for the average lambda user:

1) The default selection of formats to decode on a fresh clean install of ffdshow is slightly different from the "select all" selection of formats to decode.
To be more specific, the default selection of formats to decode on a fresh install of ffdshow does not include:
* MPEG-1
* MPEG-2
* VC-1
* ASV1/2, CYUV, ZLIB, 8BPS, LOCO, MSZH, QPEG, WNV1, VCR1
* CamStudio, ZMBV, Ultimotion, VIXL, AASC, IV32, FPS1, RT21
* FLAC
* ADPCM, MS GSM, TrueSpeech
They will only be included when you click on the top box next to "Decode the following video formats with ffdshow" and "Decode the following audio formats with ffdshow".

2) On an update of ffdshow, the list of formats to decode is slightly less than the list of formats to decode on a fresh clean install.
To be more specific, the following formats aren't listed on an update of ffdshow:
* H.261, MJPEG, Theora, VP3
* CorePNG, MS Video 1, MSRLE, Techsmith, Truemotion
* ASV1/2, CYUV, ZLIB, 8BPS, LOCO, MSZH, QPEG, WNV1, VCR1
* CamStudio, ZMBV, Ultimotion, VIXL, AASC, IV32, FPS1, RT21
* ADPCM, MS GSM, TrueSpeech

Now, I'll describe the average lambda user (like me) catastrophe scenario:
a) You install a fresh new ffdshow with default settings.
b) You try to play a video with CYUV, VCR1, IV32, or whatever codec and it won't work (because it is not enable by default ffdshow install).
c) You install the latest ffdshow build and you check all possible formats to decode.
d) You try again the same video, and it won't work again (because when updating ffdshow, only 50% of the selection of formats is displayed).


To avoid this, I would greatly appreciate a few improvements related to the ffdshow installer (especially clsid's builds). I know he told me that there was a difficulty related to save in the registry "options covering multiple formats", but then I don't see why we have the following multiple-formats options available when updating ffdshow:
* FLV1, FLV4
* SVQ1, SVQ3, Cinepak, RPZA, QTRLE
* VP5, VP6
* QDM2, MACE

I propose the following:

1) To fix first issue: default selection of formats on a fresh clean install should include the same selection as a "select all" selection (the thing when you check the top box next to "Decode the following video formats with ffdshow").

2) To fix second issue: when updating ffdshow, display the same full list of formats than a fresh clean install.

3) Additional third fix: make the "reset all ffdshow settings" option like a button that will actually really reset the selection of formats to decode to default settings.

Thanks a lot.

[Amour]

Can ffdshow decode Intel Indeo Video 5.0 Wavelet (IV50) format?

[Konrad Klar]

Also, if I choose "Decode the following video formats with ffdshow" for Xvid, DivV 4/5/6, Other MPEG4, FVFW,FFDS it is always set to libavcodec, even if Xvid was previously set as decoder for that formats. I must manually reset that formats to Xvid each time, after installation of new FFDShow.

[Amour]

In ffdshow video decoder configuration -> codecs, shouldn't it be the following?

QRPZA -> RPZA
Quicktime Video Video (QRPZA) -> Quicktime Video (RPZA)

[Inventive Software]

ffdshow doesn't decode AC-3 audio from DVDs, even though it's enabled.... the MPC-HC decoder's used even though I tell that not to!

Can somebody tell me what I'm doing wrong?

[Leak]

Can somebody tell me what I'm doing wrong?
I'm afraid I can only tell you that it works fine for me in conjunction with MPC-HC... :(

[mark0077]

Just back again to speak about aspect ratios. Definitely lots of problems relating to aspect ratio handling when resize is enabled. In my current config I can post a link to a file that shows the wrong aspect ratio.

http://www.dvdloc8.com/dolbydtsclip.php?clipid=3

This dtspiano.vob audio test which is 16:9 displays incorrect in the following setup.

Screen Resolution: 1920 x 1080
Resize & Aspect: Enabled
Resize Always
Aspect Ratio - Keep Original Aspect Ratio
Process Pixel Aspect Ratio Internally - Enabled
Lanczos - Accurate Rounding
Set Pixel Aspect Ratio In Output Media Type: Semi-Checked

mpc-hc EVR and EVR-CP tested.
mpc-hc Video Frame: Keep Aspect Ratio - Enabled

This results in an image thats much shorter height than expected. I am still having lots of trouble using ffdshow's resize due to incorrect ratios for various configurations and image ratios.

[clsid]

@Amour

Formats like MPEG-1 and MPEG-2 are disabled by default because ffdshow is not the preferred decoder for that.

Some items are hidden on updates because it is not possible to determine the "current" state of such a checkbox because it involves multiple independent registry keys. The decision was made long ago that the checkboxes should reflect the state of the users current settings, not the settings used in a previous run of the installer (which is trivial to do). There is just no way to do it right. Perhaps we should just hide everything during updates. If a user wants to change settings, the ffdshow configuration dialogs can be used.

Reset settings applies to the filter settings, not the enabled formats.

[Amour]

Thanks, but you are giving me the same answer as last time, which is not covering all the details I gave in today's post.

1) It's not just MEPG-1 and MPEG-2, it's also:
* VC-1
* ASV1/2, CYUV, ZLIB, 8BPS, LOCO, MSZH, QPEG, WNV1, VCR1
* CamStudio, ZMBV, Ultimotion, VIXL, AASC, IV32, FPS1, RT21
* FLAC
* ADPCM, MS GSM, TrueSpeech

2) If it is not possible to determine the "current" state of multiple-formats checkboxes, then it doesn't explain why/how you do it for the following:
* FLV1, FLV4
* SVQ1, SVQ3, Cinepak, RPZA, QTRLE
* VP5, VP6
* QDM2, MACE

3) The "reset all ffdshow settings" should be renamed "reset ffdshow filters" to avoid confusion.

[Amour]

Maybe we could alter/change the display of the codecs list in the ffdshow video decoder configuration dialogs to highlight or separate two different kinds of codecs:
* The codecs fully supported by ffdshow
* The codecs not preferred or not fully supported by ffdshow

This way, we would give an easy hint to simple average users (like me) about how to configure ffdshow, which decoders should be enabled and which decoders are better left disabled.

[Amour]

2) If it is not possible to determine the "current" state of multiple-formats checkboxes, then it doesn't explain why/how you do it for the following:
* FLV1, FLV4
* SVQ1, SVQ3, Cinepak, RPZA, QTRLE
* VP5, VP6
* QDM2, MACE

I got the answer to this from \trunk\bin\distrib\InnoSetup\ffdshow_installer.iss :

"FLV1, FLV4" -> it only checks "flv1"
"SVQ1, SVQ3, Cinepak, RPZA, QTRLE" -> it only checks "svq3"
"VP5, VP6" -> it only checks "vp6"
"QDM2, MACE" -> it only checks "qdm2"

Which means that any update of ffdshow will ignore previous states for FLV4, SVQ1, Cinepaq, RPZA, QTRLE, VP5, MACE.

Konrad Klar is giving hints that there might be more problems with the installation/update procedure.

[STaRGaZeR]

Some codecs are missing options in the installer, if you have DivX and Xvid decoders set to Xvid and you update ffdshow, the installer only has one checkbox for each and it doesn't know if you have libavcodec or Xvid selected as decoder. Either way the checked checkbox will always put libavcodec as decoder regardless of what you had previously. Add that to your list.

[clsid]

1) Some settings have just been chosen arbitrarily. For VC-1 of course the standard MS decoder is the recommended choice instead of ffdshow.
2) I suggest you take a look at the install script. It checks only one of the formats in those cases. Why? It simply does. It is either that or hiding them as well.
3) No it should not. The description is already correct. If you don't understand it, then well, it your fricking problem. It resets all settings. Then the settings chosen during installation are applied.
4) Nothing will get separated. The preferred settings depend on the users OS, other installed software, and personal preferences. The installer does not detect other filters (I can't be bothered to add that) and it isn't a mind reader.
5) Users that don't understand the options given in the installer should simply not touch the options and install with defaults.
6) Making the installer idiot-proof is impossible because 97,34% just presses next next next finish. 1,45% is illiterate. 0,98% is stupid beyond help. For only 0,13% it might be useful to hold their hand and guide them through the installation.

I don't use the installer, so I don't care much about it. There are few complaints about it. It works fine. Its job is to do the initial configuration. The ffdshow configuration dialogs are there to tweak the settings. Update installs are supposed to be used primarily for updating files, not for adjusting settings. If you want things changed then (1) come with better suggestions, and (2) find someone else to implement it.

Here is a deal:
If someone adds working COOK support to ffdshow, then I will 'fix' the installer.

I can't reproduce. Could you send your settings to me?

@Haruhiko: Using your ffdshow_rev2805_20090323_Q build I have trouble with this sub (http://www.mediafire.com/download.php?oti5lbz2wz0). Basically your collision handling code works differently to VSFilter starts at around 1:07. Please have a look.

[STaRGaZeR]

Very true. Problem is, next next next finish adjust settings on its own, without user intervention, instead of just updating files...

[tetsuo55]

It would be nice to have an extra selection that auto-selects all stable/recommended codecs in FFdshow.

I personally use the K-Lite Mega codecpack, and i try to have as many codecs as possible be handled by FFdshow

Thank you for feed back. {\org(x,y)} seems to cancel collision.
\org is for rotation, which is not implemented in ffdshow. The script use \org only to cancel collision.
I'll add some parser code for \org.

[Amour]

Well, clsid, currently I only know how to browse a SVN repository. I might try to learn how to compile a program, what is an .iss script, and how to do a patch.

If I manage to handle all that, I'll try to provide an improved installation/update procedure for ffdshow. I do not know if it will be faster or not than any “COOK” support.

[Amour]

Just a small question to help me started: can I compile ffdshow with Visual C++ 2008 Express Edition, or do I need to find a full edition of Visual Studio 2008? Is this thread the best place to ask about how to compile ffdshow, or is there another place with help for that?

I will send preset file now. I have the borders set to white so I can see what ffdshow is doing. In this case, there should be no white borders, but instead massive white borders are added at the top and bottom making the image squashed.

16:9 in 1920 x 1080 (should be no white bars at all, instead white bars at top and bottom).

I am becoming frustrated with Windows 7 :

This is no longer possible to decode divx/xvid/h264 within FFDShow, whatever used technology (DirectShow, Media Foundation)

This is no longer possible to have raw processing (worked in XP, worked in Vista with a hack).

So let's say that about 99% of your videos won't play with FFDSHow.

I just had the confirmation from MS.

I am talking about MS applications : windows media center and media player. MPC for example still works fine with FFDSHow

For us, this is annoying but we do this for free, but for Divx networks, core codec, ... this is another story

[Amour]

I heard that Windows Media Player can be uninstalled from Windows 7.

If that is the case, then we can try in the future to advertise this way:
Install MPC and uninstall WMP!

Also, it would be interesting to know the following ratio:
* How many people are using ffdshow with WMP
* How many people are using ffdshow with an alternative player

Did MS actually confirm that Media Center (in Windows 7) will be locked down to just use codecs from Microsoft for divx/xvid/h264 even in the final release?

[albain]

No, there is (little) hope that this is a bug.

However, I made my tests on build 7057, which is nearly Release Candidate

Concerning the debate : who use WMP, I would say many people, because of Media Center, which has no equivalent these days

[Jeremy Duncan]

clsid,

You said to the amour that visual studio with sdk 2007 august can build ffdshow. This makes me ask a question. Does the ffdshow have a src with a dsw or vcproj file that visual studio can open and just build ffdshow?

[clsid]

Why would there not be any project files for Visual Studio? We all use it to compile ffdshow, so yes, they are present in our source repository ;)


@albain
Perhaps Haali could add a tweak to his splitter to (optionally) force ffdshow's video processor into the graph. It already is able to do that with DirectVobSub and that still works with WMP on Windows 7. Then at least ffdshow could be used when playing .mkv files.

[therealjoeblow]

I can't reproduce. Toggling resize during playback is a basic feature of ffdshow, fully tested and shouldn't be a common bug to everyone. Please try to find something in your filter graph that prevents reconnecting. ffdshow may be connected to some filter other than video renderer.
You could check the status of "Allow output format changes during playback" in "Output" page.

Thanks, and sorry for the false alarm - after testing a bunch more files and looking at haruhiko's suggestions, the resize freeze bug only occurred on some files, not all of them; and in looking at the filter graph, for the problematic files, ffdshow was connecting it's output pins to directvobsub in those cases. It just so happened that the half dozen or so I tested the first time around all had subtitles :-( and in reinstalling AutoGK recently, directvobsub got reenabled.

In testing, I temporarily removed the subtitle files which stopped directvobsub from loading and the resize works for what I thought were the "glitch" videos, so my bad. Now I've disabled directvobsub completely from loading and all is well.

Sorry again for the false alarm.

Cheers,
The REAL Joe

Update about the corruption issues when seeking with ffmpeg-mt:

- Progressive material --> Completely gone with the lastest changes in EVR by Beliyaal. So forget about this one.

- PAFF material --> Gone.

- MBAFF material --> Still there, plus ocasional decoding artifacts when normal playing like ikarad reported. Some are random and some are fixed, with all renderers (even overlay), and they look like this:

DirectX SDK August 2007 is the only extra thing that is needed.

I thought that “August 2007” would be some minimal requirement, but I was wrong: any later release of DirectX SDK is missing dinput.lib!

[edit]
Ok, I can work-around that by doing:
Project -> Properties -> Configuration Properties -> Linker -> Input -> Additional Dependancies
And then I replace dinput.lib with dinput8.lib.

Unfortunatly, it doesn't help to compile to the end of the project.

[edit]
Revision 2811 by clsid2:
“Simplified install script. Tasks are now only shown at the initial installation and are hidden when updating.”

...

Thanks.

Also it would be a good idea to implement such an option in gabest matroska splitter too ?
