ffdshow tryouts project: Discussion & Development

[kc7bfi]

I am trying to understand the code as to how the video decoder retrieves the video samples from the source filter. Are they pushed in or pulled by the decoder. Any help or insight would be appreciated. David

[nevcairiel]

The source filter pushes samples.

I believe the buffer should be big enough to keep about a whole GOP, because AVC requires a lot of frames available to encode efficiently with enough references for bidirectionally predicted (B-) frames...

Guys, I use ffdshow raw video filter for avisynth double frame rate scripts. When using ffdshow however I lose out on subtitles, they just don't appear anymore. Is there a way to stop ffdshow doing this?

I'm using mpc-be, madVR and LAV Filters / Splitters. I just want ffdshow to double frame rate, nothing else, and nothing other than avisynth is checked in the list of filters.

I know that the development of FFDShow is more or less dead but it remains currently the only tool available for post processing. And I have an issue with it, independently of the version I tried. I don't know if it is a bug or a misconfiguration. I hope someone can help me.

My issue is concerning only DVD as all works fine with MKV, Blu-ray,.... I use Lavfilter to decode video and MadVR as renderer. If FFDShow is not present on the graph, all is ok in terms of information sent to MadVR (Framerate, colorspace, deinterlacing,...):


But as soon as FFDShow is present on the graph (even if no filter is selected), the information sent to MadVR are completely wrong (Framerate, Colorspace as MadVR is deducting it from the framerate because no information is sent to it, deintrelacing...):


I tried several version of FFDShow, players,set up,... each time I get this issue.

Someone can help me?

Thanks in advance.

Wouldn't be time to start a new ffdshow thread like MPC-HC?

Fixed in 4495.

Cheers Clsid!!

[ryrynz]

clsid can you build with VS2012?

Hi.

I would like to use FFDshow subtitles filter with 10-bit videos, because FFDShow is only one that gives you change to make different profiles for 2D and 3D movies. Problem is that it won't load when input is 10-bit (P010 or P210) or NV12.
If I have understanded right it should work if I could select P010 and P210 support in RAW video?

[nevcairiel]

I don't think ffdshow supports 10-bit input, or ever will. Its mostly dead now.

[NiFa]

Is there any other subtitles filter that gives possibility to play 3D subs?

Does anyone know why FFDShow give me this error? I mean, for me the Pin Out Data should be the same that the Pin Out ones (except for color maybe as I not unchecked NV12 box), especially regarding the FPS but it is not:

Pin In:


Pin Out:


(I use no filter in FFDshow for this test)

I try several FFDShow version, even one from 2004 and I got exactly the same error each time. Do I make something wrong or it is a bug?

Hi,

I've got a problem. I had a profile which must match a certain movie dimension AND application exe filename, it works. But I need some tweaking for movie file names which does contain the "3D" pattern.

So I duplicated the profile, did the tweaking, and in the autoload preset conditions, I added "on movie file name match", but it doesn't work.
I tried prefixing my files with pattern "3D_moviename.ext", using "3D_*" pattern but my preset didn't be taken.
I tried "*.3D.*" for files named "moviename.3D.ext", but nothing.

How does it work and how to prevent the other profile to be taken ? There should be negative conditions "on movie file name not match"

Thanks by advance

[clsid]

It seems a bit buggy. But "*[3D]*" works here for "moviename_[3D].ext".

Hi, I'm using clsid build 4496 on my machine. I installed a piece of software that set ffdshow video decoder (which I don't use), merit to "default". I can't set it back to "do not use". I hit apply / ok, but the setting doesn't seem to save.

If I reopen the video decoder dialog, its set back to "default". I wonder is this a quick fix?

[clsid]

Right-click on the config shortcut and choose 'run as administrator'.

[mark0077]

oh wow never had to do that in Windows 7, thanks clsid!

Hi,

I am using ffdshow tryouts rev4496 on WinXP.
I found that there are some problem in using ffvfw interface.
It works fine when using YV12/YUY2/UYVY/AYUV output but not others.

Source video is H.264 with embedding sps and pps at every I-Frame.

For NV12 output, ICDecompressBegin replies ICERR_OK but ICDecompress replies ICERR_UNSUPPORTED.

For Y416 output, ICDecompress replies ICERR_OK but nothing is written to the output buffer.

For P010/P210/P016/P216 output, access violation occurs. I have check the output buffer, only Y data are written. No U/V data found.
