Hi,authors
Thank you for your efforts.

I can't playback(weird color/block noise?) this sample in wmv3(libavcodec).(ff_wmv9 is fine)
http://tirnanog.fate.jp/tmp/sample/wmv3/FullMetal%5bwmv+AAC%5d_remux-006.mkv
As for this sample works fine with libavcodec/ff_wmv9 either.
http://tirnanog.fate.jp/tmp/sample/wmv3/Bebop%5bwmv+AC3%5d_remux-004.mkv
I have tested with mpc/wmp10 and haali/gabest splitter.
Can anyone reproduce?

Regards.

Hi,

I can reproduce your playback problem (weird color/block noise).
I only have the problem with WMV3 set to libavcodec

Tested:
directvobsub 2.37 + ffdshow-rev899_20070209_gcc_xxl +WMP
Bug, more vobsub bug, than ffdshow. May i guess, that that video have non-standart dimensions, like 638x478 instead of 640x480?

With the recent builds (I'm running 973) and VSfilter *OR* Vobsub and not at the same time, WMP11 just sits there if there are subtitles in the same folder as the AVI. In fact VistaMC just crashes altogether claiming the culprit is either VSfilter or Vobsub.

I was scratching my head over that one for a while until I rememberd the 'subtitles' section in ffdshow. If I check that off, things seem to be normal. Strange thing is that I never had to check that off before. :o

and in the ffdshow audio there are:
WMA 7
WMA 8/9
Actually, WMA7, WMA8 and WMA9 are all the same codec = WMA v2. The older v1 was used in products that I don't think even carried the Windows Media name, like MSN Audio or something. There really isn't a v3, unless you count Pro and Lossless as v3, but nobody does that.

I'm using drevil_xxl's build. Since rev978, there's compatible issue with CrystalPlayer. Cannot configure ffdshow within player and thus the output color space wont be YV12. Besides, the picture is upside down.

The last working build is rev964.

Edit: Just tried with success under Administrator. While I'm working under another restricted account, could that be the problem? How could I fix it?

Is there a wikipage or something which lists what the different options in ffdshow do?

The number of things you can do is almost overwhelming without a decent documentation.

3rd March 2007, 07:09

I'm not very versed on how inno and nsis work, so I'll leave it to you guys. But I found out from akupenguin that the default keyframe distance in FFV1 is way, way too high, and should be reset to 2-10 or so. 2 would probably be fine (4% larger), if you want to know how much loss in involved vs 300 frames:

1 - 7%
2 - 4%
3 - 3%
5 - 2%
10 - 1%

If you could set it to force a lower value if upgrading from an older version, that'd be cool. If anyone really needs it, I doubt it's a major inconvenience to reset it.

i thought crystal-player had its own codecs/filters

MPEG 1 and 2 are build inside the player, but xVid, DivX and H.264/AVC don't. I don't know about FLV (can't open), and WMV I'm not sure, but I think that it uses external codec.

BTW, this player has an amazing option called 'motion morphing' that is similar to the TrimensionDNM (from WinDVD), but unfortunately still has some bugs. :(

Regarding your keyframes in FFV1 foxy, isn't that cause it doesn't really have delta-frames implemented as efficiently as, say, MSU?

Well, akupenguin explained to me that it doesn't use delta frames at all in the classic sense. It only keeps context (dictionaries) around for future frames, sort of like rar solid archiving. He had a patch for delta frames that sounds cool and majorly effective, but it was never finished.

I was extremely surprised, actually, because I thought it was simply impossible to get that level of performance - the most efficient lossless video codec I've used - without advanced inter prediction. But then again, it only gives marginal gains to MSU as well, about 4% on my test case. (ending up about the same as ffv1 with 3 kf dist, and w/o it's a bit larger than ffv1 pure intra) Maybe MSU doesn't use deltas either, just context.

It's probably only really effective with true duplicate frames or 90% duplicates.

akupenguin

4th March 2007, 11:53

Maybe MSU doesn't use deltas either, just context.
MSU has a "Motion Estimation" tab. They wouldn't call it that if it didn't use conventional delta frames.

ffdshow sets wrong merit for mpeg1 audio, I hate this decoder. I am using Vista x64 and there are no x64 merit changers available. Had to change the merits manually, both for MS Audio Mpeg decoder and ffdshow audio decoder. Why the hell are they doing this? Nobody would use this decoder unless absolutely necessary. I only installed it, because I couldn't find a x64 version of the intervideo decoders I usually use. I don't need it to decode mpeg1, because MS already provides a decoder for this purpose.

There is not a single x64 dx decoder for dvd available, so one would thing the ffdshow developers would invest their time in adding this function. Instead, they develop an mpeg1 decoder? which nobody needs! and then forcing people to use it?! how ugly is that?!!

To change the merits, go to

HKEY_CLASSES_ROOT\CLSID\{083863F1-70DE-11D0-BD40-00A0C911CE86}\Instance\{0F40E1E5-4F79-4988-B1A9-CC98794E6B55}

and

HKEY_CLASSES_ROOT\CLSID\{083863F1-70DE-11D0-BD40-00A0C911CE86}\Instance\{4A2286E0-7BEF-11CE-9BD9-0000E202599C}

the first one is the ffdshow crappy decoder, the second is the good old MS one. the merit starts (or rather ends, it's the other way around for some reason) with the fifth hex byte, set 00,00,60,00 for ffdshow and 00,00,80,00 for MS audio. or rather, you know what? set the ffdshow to 0x200001, that's just 1 above the do_not_use value. 'cause this decoder is as crappy as the mainconcept decoders that can't decode anything, but set the highest merit possible.

If someone knows of a x64 dx dvd decoder, please tell me. Can't even watch my favorite movies on x64 version of WMP, what a shame

Whoa there - did ffdshow's audio decoder run over your dog or something? :confused:

Instead of flaming about how ffdshow "sets the wrong merit" you could just have opened it's audio config dialog, gone to the "Codecs" page and just disabled the much hated "MP1/MP2" decoder or chosen to use libmad instead of mp3lib if it's quality is that bad.

Please do some research next time instead of making yourself look silly here...

I can't disable the mp2 decoder, because that's the only reason I installed this thing. the problem is that it's coupled with mp1 decoder for some reason, so you can't disable one without disabling the other one at the same time.

and yes, I tried the other mpeg2 decoder too, the libmad thingy, so what? ffdshow still decodes mpeg1, unless you change the merit. it's not even so much about ffdshow, but I've witnessed too many decoders in my life which are completely useless and still set high merits. those bundled with soundforge, the mainconcept crap, are a good example. please, just let the user decide! the developers always think they know better than the consumers.

5th March 2007, 09:55

In other things... it looks like I finally have succeeded to make an updated AviSynth filter that allows AviSynth some limited access to frames other than the current one (by buffering a specified amount of frames ahead and back) *and* makes it possible to actually drop or add frames (as long as it does so uniformly across the whole clip).

I.e. you can use stuff like TIVTC (which was my main motivation), Decomb, temporal filters and such on-the-fly... :D

I've also added an option to actually honor the interlace flags set by the decoder and apply 3:2 pulldown to the video before handing the frames to AviSynth - that helps a lot with smoothness if the flags on the video are horrible and you IVTC it yourself instead.

Of course, since my current code is mostly frankensteined together I'll need to go over it again to make a submittable patch and clean up some other stuff, and I still have to add the new options to the config dialog.

Anyway, if the patch is ready to go, who/where do I send it to? Or should I post it to the patches tracker on Sourceforge?

Also - is there a way to detect that the end of the stream has been hit? I'd need to deliver all samples still in the buffer at that point, as currently those silently get dropped - then again, dropping ~5 frames at the end of an episode or a movie probably is peanuts if everything else was properly IVTCed... :)

Well, how about just asking to uncouple the MP1 and MP2 decoders on the config page then?

Also, the tone of your first post above was just rude - what was that meant to accomplish?

Subtitle suggestion:

Currently a user must choose between "Search in" and "File". I prefer (heuristic) search, but occasionally I manually need to select the correct file (from "subtitle sources"). Problem is that ffdshow remembers that setting. So next time I use it with a different video, it will use the wrong subs.

My suggestion is to remove the radio buttons. ffdshow should always use the Search method. A user can override the selected sub when needed by using the File field. That sub should then be used during the active session only.

uICE can be downloaded from here... http://www.mediatexx.com/ it's only $20 vs $100 for Proximis Girder so I really would like some help on figuring out how to make it work with ffdshow so I can use this one. It also works 100x better with my serial port X10 remote while Proximis Girder will keep messing up the remote commands.

Okay... it's probably gonna take a wee bit longer yet, as I hadn't taken into account that static DVD menus don't like simply being buffered for a certain number of frames because they'll never get displayed due to there being no notification that the remaining frames need to be flushed.

That's why I had to make a small modification to tvideocodeclibmpeg2.cpp/.h as well to signal the end of an MPEG2 sequence inside the picture's fieldtype flags. If that flag is encountered, the AviSynth filter will now flush all buffered frames and then reset the AviSynth environment, which is a bit ugly but also about the only way to make sure nothing is left in AviSynth's cache...

Oh yeah - code for applying 3:2 pulldown according to the TFF/BFF flags was also neccessary in turn to fix badly flagged DVDs with TIVTC.

So what's left is extending the UI to make the filter configurable, making a patch, testing it against a recent SVN checkout and submitting it, but I'll leave that for tomorrow. *yawn*

Oh yeah, another thing - while working with ffdshow as an MPEG2 decoder I noticed a total absence of DVD subtitles; am I right to assume that decoding/displaying of those is not implemented yet, or did I forget to throw a switch somewhere in the config dialogs?

Leak, thanks for your efforts in the cleanup. For me, watching a DVD with subtitles just requires me to right click in the window and select the subtitle from the sub-menu. Is this what you were looking for? Now that I think about it that might be MPC's sub engine :-\

I can only second the first sentence. :)

As to MPEG-2 subtitles, there are none ... :( MPC's internal engine renders them in VMR9 and VMR7 renderless modes, which I don't use (VMR7 windowed as a rule). A fellow like me is derived of all possibilities of having DVD subtitles - MPC's splitter indicates their presence, but they cannot be rendered - neither while using MPC's MPEG-2 decoder (works better) nor ffdshow's one (works a bit worse, though has improved much recently).

If ffdshow's MPEG-2 decoding improved, then I could use VMR9 renderless + HQ RGB32. Internal ffdshow's support would be nice, though. ;)

@ clsid
Thanks a bunch for the latest 1006 ICL9 build! :)

By simple watching, if you don't touch the keyboard, absolutely nothing. Artefacts (usually some macroblocks) appear while seeking/skipping + you've got to wait a while (from 1 sec to eternity ;)).

I know it has really improved much somewhere after ICL9 743 (which still had many artefacts), as I wrote above.

It seems there is a compatibility problem with Haali Filter and Ffdshow tryouts. The Video is accelerated at 29.97 fps instead of staying at 23.976 and Audio / Video gets out sync
when an EVO with VC1 is played.

It occurs if Ffdshow is added in the DirectShow chain that is:
- if Ffdshow is the VC1 decoder with either choice of codec
- if WMVVideo is the VC1 decoder and is followed by Ffdshow in the DirectShow chain

If WMVVideo is used alone there isn't any audio / video sync problem.

My assumption is that Telecine flags such as "Repeat field" are ignored by the the Ffshow filter.
