ffdshow tryouts project: Discussion & Development

[clsid]

The problem is caused by r4260, in which support for interlaced VC-1 was added.

is it possible to use ffdshow with windows media player 12 to play dvds?!? i can't figure to work the mpeg2 option even disabling win7 codecs...thanks

[FlashGordon]

I think I've found a glitch with the MPEG2 libavcodec decoder. The skips happen when I open the DVD from the VIDEO_TS.IFO file. The glitch is 100% reproducible for me and the skips happen at the same exact spots. If I open the VOB by itself using LAV video decoder, the skips do not occur. If I open the VIDEO_TS.IFO using the MPC-HC mpeg2 decoder, the skips do not occur. Here is a sample: http://www.mediafire.com/download.php?im9htdjxo3v2kp7

EDIT: I tested the sample on my other machine and the skips are still there with latest ffdshow. Also, I realized depositfiles requires a 60 second wait, a captcha, and a 20 minute download time... so I updated the link to mediafire

I've added HW deinterlacing, detail and denoise to the Intel QuickSync Decoder.
I don't want to commit my changes before there's some kind of GUI (in ffdshow) to control these.
My preferred option is to create a new tab instead of changing existing ones.
Can someone give me some pointers?

How may options are we talking about?
You could add a page below "Decoder options" if you need a lot of space. Or add to the "Decoder options" page if just a few options. The IDCT and quant options could be removed imo to free up some extra space on that page.

[egur]

I'd like to add a new page - below the decoder options is fine.
I want to add options for:
* HW DI on/off/force, half/full rate, etc.
* Denoise filter
* Detail filter
* procamp filter
These will only work with the Intel QuickSync Decoder - covers most of the video content these days.

[egur]

Committed several small changes:
Synced with latest QS decoder - video post processing is hard coded off until GUI is ready.
Fixed telecine manager - detected H264 frame doubling/tripling flags as 3:2.
Tweaked fps calculation - more stable.

[egur]

Last commit:
Added "Intel QuickSync" page below the decoder options.

[Delerue]

It seems that resize has broken DVD menus navigation again.

Edit: I mean, with 'Keep original aspect ratio' selected.

Is there any chance to fix this?

What does this mean? Is backward compatibility with vobsub broken somehow?

I tried build 4453 and just noticed this change.

My problem... If I use just VobSub/vsfilter for IDX/SUB subtitles, I see double subtitles when playing SRT subtitles. If I disable ffdshow's text subtitles, it works, but I loose the nice extras in ffdshow. Does anyone have any ideas what I can do to make ffdshow the only one that displays for SRTs?

I've gone back to build 4422 for now.

Hi, is it possible to set Profiles/Preset Settings by file extension (ie FLV, AVI, MP4 etc)? If so how to do you that as I don't see any option to select file extensions when I click "Preset Autoload Conditions..."

Cheers much

Try "on movie file name match (with wildcards)".

Hello, used ffdshow_rev4422_20120409.exe

Accroding to spec for VC1 there is no restrict to change it during the stream http://rfc-ref.org/RFC-TEXTS/4425/chapter4.html
4.6. Repeating the Sequence Layer Header

Here is sample file that hangs on decoding the stream, using

WMVideo Decoder DMO it plays fine:
http://dl.dropbox.com/u/9992211/crash.wmv

The sequence layer and entry layer changes during the stream:

00 00 01 0f cb ee 13 f0 ef 88 80 
00 00 01 0e 18 44 4f c3 bc 80 
00 00 01 0f cb ef 13 f0 ef 0a 13 f8 3b f1 c0 ef 90 81 2d c6 db 8d 40 
00 00 01 0e 4a 3f 28 40 00 00 01 0e 4a 3b 98 40

another one that gives broken image at the beginning,using WMVideo Decoder DMO it plays fine

http://dl.dropbox.com/u/9992211/broken.wmv

The sequence layer and entry layer changes during the stream:

00 00 01 0f ca 00 13 f0 ef 0a 13 f8 3b f1 c0 ef 88
00 00 01 0e 4c 10 80 
00 00 01 0f cb ef 13 f0 ef 0a 13 f8 3b f1 c0 ef 90 81 2d c6 db 8d 40 00 00 01 0e 4a 3f 28 40 
00 00 01 0e 4a 3b 98 40

The question: Is it problem of the decoder, that doesn't support changing of sequence layer, or in the stream itself?

Cheers, got it sorted. *.flv, *.mp4 etc :-)

Because, with the latest FFDShow and LAV Filters versions, the aac audio stream of this particular video is still incorrectly being decoded here, I was wondering if it could be a WinXP-only issue.

Traps' movie trailer plays fine for me too. But then I realized the issue I had with AAC Audio some time ago is gone now. Suddenly no problems anymore decoding Standard720x576_1MBit.mp4 with libavcodec. Don't know since when this is fixed and I have no idea what could've caused it, but anyway...good job!

Recently I noticed this post implying that the software scaler in ffdshow doesn't work with 10-bit video. Is it a limitation of ffmpeg/libav's swscale, or is it just something that hasn't been enabled ffdshow-side?

I want to ask, is it possible to add ability to prefer connection to ASIO Renderer to ffdshow audio filter (Output section, "Connect to:" menu)? It's CLSID is {8E14549A-DB61-4309-AFA1-3578E927E933}

Hi,
I've encountered an issue/bug when using ffdshow's subtitle renderer filter.
What I'm trying to do is build a graph where the ffdshow subtitle renderer is connected to the video decoder and the external subtitle file resides in a different directory entirely.

I'm trying to use the API to manually specify the subtitle file by calling the "IffDecoder2" interface like this:
putParam(IDFF_isSubtitles,Integer(True)); // Make sure subtitle processing is enabled.
putParam(IDFF_subAutoFlnm,Integer(False)); // Supposed to disable the auto-searching for sub files in the same dir as menu file.
putParamStrW(IDFF_subFilename,@SubFileLoad[1]); // Set the subtitle filename.

There are two issues:
1. The 'search in' radio-item remains checked rather than the 'file' radio-item becoming enabled and the subs are not rendered.
2. The IAMStreamSelect interface that lists the available subtitles doesn't see to be properly updated when using this method, even when manually switching to 'file' and clicking on the 'reload' button.

Am I doing something wrong? Can this be fixed?

The project seems to be given up.. sigh..
