ffdshow tryouts project: Discussion & Development

[clsid]

It is actually already possible right now to use ffdshow as a post-processor after LAV Video decoder. Benefit of the proposed method is that it allows using a small whitelist, and thus less chance of compatibility issues with other apps.

It is unknown when or if it will be implemented in LAV. So it could take a long time before it is available.

I understand development on this project is inactive, but I have a quick question. Has anyone ever been able to get the Crop/Zoom function to work properly? It seems cropping is uneven no matter if all sides are set to the same value. For example, if horizontal and vertical zoom are set to 1, it'll crop more on the bottom than on the rest of the sides. I tested both Crop and Zoom at different settings using a variety of builds (including last one) with a Spears & Munsil test pattern with no luck.

I use mpc-hc and the PnS Inc Size command isn't very precise (it'll crop too much). Basically, I'd like the ability to crop in smaller increments on the fly and in an even manner. Any ideas?

[mandarinka]

IIRC the crop requires rather large increments to be used (4 or even 8?). I suggest using avisynth filtering...

[mindbomb]

question about LFE crossover:
"Remove low frequencies added to LFE from left and right channel" - does this also remove the low frequencies from the center and surround in a 5.1 configuration?

Please understand that ffdshow development is inactive. ....

Hi clsid,

Q: What is the last "Stable" version that would work good with Vista?

Thanks,

G! :)

[ryrynz]

Any of them since the last stable release really, current is 4512.

Hi ryrynz,

Thanks! Just out of curisoity ... is this what you are running and what is your OS?

G! :thanks:

[ryrynz]

Running Eric Gur's 4512 build found here (http://sourceforge.net/projects/qsdecoder/) on Windows 7 x64.

[filler56789]

Latest revision is 4514. Available at xvidvideo.ru :eek:

[ryrynz]

Hey clsid, are there any chances of getting something like on 'directory name match' added to the preset auto conditions? Surely it it be fairly trivial to add this feature?

[clsid]

Submit a patch...

Should be fixed in r4516.

Where I can find FFV1 vfw ?

[LigH]

When you installed ffdshow, it also registers a VfW multi-codec in parallel to the DirectShow multi-decoder.

[djonline]

LigHThere is no "Encoder" tab in latest ffdshow from this year.

[clsid]

Then you are looking in the wrong place. It is in the VFW codec, not in the DirectShow filter.

[LigH]

I believe the yellow icon should help you finding the right link in its start menu.

[ryrynz]

Why is it if I play a 10bit file with ffdshow raw active (on a default profile with no options ticked) it outputs NV12?
I know I could unticket all output options but P010 which hopefully avoids any conversion (does it?) but I shouldn't have to.
I have all output options ticked so shouldn't it default to P010? What's going on?

[nevcairiel]

ffdshow raw does not support 10-bit input, so its converted before it reaches ffdshow already, IIRC.

[djonline]

clsid, Encoder tab was completely removed from ffdshow more than half year ago. But still there is no VFW replacement for FFV1.

[LigH]

Several VfW codecs have been removed from the VfW configuration's Encoder tab (e.g. the generic MPEG4-ASP codec with insanely detailed configurability but only experimental, in comparison to Xvid not really practical capabilities). But there are still a few essential codecs left. Namely the unsubstitutable lossless codecs (FFV1 and Huffyuv with YV12 support), as well as the top quality Motion-JPEG and DV implementations.

[foxyshadis]

Try completely uninstalling ffdshow and reinstalling one of clsid's compiles. You might be working with someone else's build.

ffdshow dxva subtitles(pgs) is imperfect:

[clsid]

Wrong. The video has a too small size. That is fault of encoder.

[shunely]

Wrong. The video has a too small size. That is fault of encoder.

ffdshowvideo subtitles(pgs) is correct.

[kirakami]

can you implement Opus (http://www.opus-codec.org) in ffdshow audio decoder? :)

[LigH]

I thought I had installed everything correctly ... but then I got the old known error in VirtualDubMod again: "Source format not acceptable (-2)" when loading an AviSynth script which outputs YV12 video. I knew that it can be solved by registering a VfW handler for the "YV12" FourCC in the Registry.

So I called the VFW Configuration of ffdshow and checked the "Codecs" page in the "Decoder" register. Raw formats: "all supported". :confused:

Set to "none"; [Apply]; Set back to "all supported"; [Apply]; still Error -2 in VDubMod. :eek:

RegEdit; search for "vidc."; found some in:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32

But neither contains "vidc.yv12". :mad:

Manually added String value "vidc.yv12=ff_vfw.dll" for both.

Works again. :p — But why disappeared this entry, and why is ffdshow not anymore able to register itself? :(

[clsid]

It has never created that entry. Afaik it is also not needed. A VFW codec can support multiple formats with a single entry. It is possible that is doesn't communicate YV12 as a supported format by default (assumption).

Alternative solutions:
- Xvid VFW codec
- Helix YV12 VFW codec
- Enabling raw video in the ffdshow DirectShow filter

[LigH]

I thought that a VfW codec needs to register itself as responsible for a FourCC by assigning the vidc.fourcc registry value to its DLL. I did not know that there are other ways of registering. Especially not that registering as responsible DirectShow decoder is of any interest for VfW.

Indeed, raw formats were disabled in the ffdshow DirectShow Decoder Configuration; no clue why...

[clsid]

While VirtualDub uses VfW, it is of course possible to use something different in AviSynth, like DirectShowSource.

Raw video is disabled by default for good reasons. Otherwise it would insert itself in every graph.

[Reino]

Changing FFDShow RAW Video Decoder its merit to 00400000 ('unlikely') solves that issue. It won't insert it self in every graph, but only when it's really necessary.

Btw, another alternative solution, albeit non-VFW, is madVR.

[betaking]

There are plans to support VS 2012 compile it?

[4evrplan]

I know that ffdshow-tryouts was forked because ffdshow wasn't being developed anymore, but the sourceforge page says "Last Update: 2013-05-09". Did someone pick up the torch? If so, how do I decide between the two?

[clsid]

The original project hasn't been updated since 2006.

I believe you, but does anyone know why the misleading date on the project page?

[itsonlyjustincase]

Hi,

if i modify for example "ffmpeg.dll", and replace it with another modified version, will this enough to have the new file working ?

[clsid]

I believe you, but does anyone know why the misleading date on the project page? Probably just the date at which the project got updated to new SourceForge website layout and project back-end.

if i modify for example "ffmpeg.dll", and replace it with another modified version, will this enough to have the new file working ? As long as you don't change any API functions, it should work.

Hello!

Are there any plans to include the latest version of FFV1 [version 3] in ffdshow tryouts?

Thanks,

Erik

[clsid]

There are no developers available that are interested in working on ffdshow.

[ipanema]

I would like to add a program entry to the whitelist programmatically.

The whitelist seems to be stored in the registry at

HKCU\Software\GNU\ffdshow\whitelist

so just appending an extra program name to it works OK.

However, if the "video decoder configuration" tool has never been run for that user then the whole of that branch in the registry does not exist yet, so there is no existing whitelist to append to. Only after the "video decoder configuration" tool has been run and saved does the whitelist value get created with a long list of program names.

To cope with situations where the tool has not been run yet, I need to get the default list from somewhere. I have tried searching the whole registry but I can't seem to find it.

How can I get the default list?

[clsid]

The default whitelist is embedded in the binary. You can disable the whitelist through this value: isWhitelist.

What is the filename of the program?

[PetitDragon]

@clsid
Thanks for the new update of ffdshow.:thanks:

[WorBry]

Hi,

Having just recently upgraded my ancient single-core PC to a 6-core (AMD FX-6300) PC, I've come to realize that FFDShow vfw doesn't provide MT support for HuffYuv, my long preferred lossless YV12 format.

I know there's FFV1, but is there any (custom) build out there that offers HuffYuv MT support?

Just asking :o

[WorBry]

I'll take that as a 'no' then? :o

[clsid]

The decoders and encoders in ffdshow have not been updated since 2012, and it is extremely unlikely that they will get updated in the future, since the project is dead.

Alternative lossless codecs are Lagarith and UTvideo.

[WorBry]

OK, thanks. I guess it's a bit late to send flowers?
