What OS? I tried uninstalling / reinstalling, no problem here on WinXPsp1

worked now :)
edit: tough i dont have ffvfw listed in vdm now, but a "ffdshow video codec" with no options

@ bond:

When I uninstalled ffvfw and the old ffdshow (up to Feb. 2004), and installed the previous ffdshow (2004-03-25) with VfW interface, I got this "ffdshow" codec entry, and it was fully configurable. It substituted ffvfw well. And it was configurable via Start menu as well as from VDub.

After uninstalling 2004-03-25 and installing 2004-04-05, it still works well.

Using Windows 2000 SP4 (german: "Programme").

sorry to hear this, but seems it only fixed the OM1 choppy playback and "semi" for OM2. Some reported success for OM2 some did not...

[skynetman]

Ohhhhhh no!! :angry:

CRASH AGAIN with latest 20040405 build :(

01457BD7 movzx ebx,byte ptr [eax+3]


Besides it didn't want to overwrite my old ffdshow.ax, i had to rename it and launch setup again.

The gain/offset crash? im still on it will send the fix to athos if its done.

[Blight]

Regarding the OM1 vs OM2 issue... why is anyone using OM2? As far as I can see, there's no reason to use it as OM1 does support Format_VIDEOINFO2... It's just not an auto-loading filter... OM2 was introduced solely for autoamtic DVD graph creation as far as I can tell, and as most of you know, creating a DVD Graph automatically has a very high chance of failing or creating an unwanted graph.

Neither ZP, MPC and BSPlayer (I think) load OM automatically...

why ffdshow audio doesn't work?.
it gives a lot of rare sounds, but doesn't decode mp3.
somebody know's if that is gonna be fixed?

thanks

mhh what u mean with "but doesn't decode mp3"? Just configure it for mp3 playback and select "libmad"

I just tested it and my avi's with mp3 sound play just fine using ffdshow audio filter, so whats your problem? (crash/no sound/ ...)

PS: but i like the elecard moonlight "odio dekoda" more since it play's mpg1/2/2.5/3 and i never had problem's with out of sync or whatever problem's

[tato_uy]

with
mp3lib: glitches and strange sounds. A little of the original sound can be heard.
libmad: no sound at all.

i tested on 3 different machines with win2000 and winXP.

mhh for me libmad works fine... but it seems im the only one where ffdshow works like a charm (no choppy playback, never ever a crash, working sound..) sometimes i wish i would have those bug's since those dbugging with zillion's of testversion's suck..

Put this bug on the todo list, but its not a high priority atm... just use a windows or download a other filter. U can also get the libmad dshow filter as seperate "working" install.

get all here: http://www.rarewares.org/

[tato_uy]

thanks, is weird, because audio filter never worked for me. And i tested on a lot of computers.
Yes, currently i'm using
http://sourceforge.net/projects/maddxshow/
or the fraunhofer decoder.

if i can help you with some tests, let me know!

try this one: http://mitglied.lycos.de/ieggei2/dshowfilters
get the "odio.zip"

unpack, and in cmd "regsvr32 mlcom.ax" and select "odio decoda" later as filter for all mpeg audio.

"....(I'm not Crystal Player developer)" -> hehe rofl

[LigH]

Just a question about decoding audio: Windows 2000 and XP audio drivers shall be able to process even single precision float samples - Windows 9x drivers may in general not be able to do that. But I'd wonder if Windows 2K/XP will reliably always support other sample formats than 16 bit integer.

Might that be any reason for such "glitches"?

[zettai]

I had a custom installer that would register VIDC.YV12 to ffvfw.dll and I was looking to see if I could get similar functionality somehow with the new combined ffdshow and ffvfw?

I know I can manually set ffdshow to decode YV12 raw content but I'm not sure what registry setting I should enable for this. Any ideas?

I posted bug report into CrystalPlayer's forum

[tickey]

With the last few builds it seems I only get 25 fps w/mpeg2 encoder, even though source is 23.97 or 29.97.
If I use the mpeg2enc mpeg2 I can set the frame rate OK, but I prefer the main mpeg2 encoder.
Anyone else having these problems?
Happens in full procesing or fast recompress.
Happens if set frame rate in vdub, etc.
TIA

athos,
in the past every time i tried the newer ffdshow builds, i would get an instant crash upon playing a vid. i always ended up reverting back to the 20030523 build. just recently i got fed up and uninstalled all of the video related stuff, and installed media player classic again along with your newest ffdshow (0405). everything worked (yay), but then when i tried tweaking ffdshow settings i discovered what had been causing my crash all along:

under picture properties - adjusting either of the top 2 luminance sliders causes an instant crash with media player classic. mpc will then crash on every launch until ffdshow is set back to the normals for those 2 sliders.

my hardware:
geforce4 ti4200
dual xeon
1 gig ram

software:
newest nvidia reference drivers (crashed under the past few that i've tried)
newest mpc (also - crashed under the past few that i've tried)
xp sp1 / dx9
(note: also tried this under a clean install and got same result)

other notes: gamma adjustment works fine, as well as adjusting the 'levels' section (i'm currently using that adjustment to 'get by').

lemme know if you need any more info to replicate, or if you have any clue as to the cause of the crash.

p.s. is your source gonna show up on sourceforge in the future? we could help you out with the coding ya know... :)

p.s.2. why isnt your name in the about section? it appears you are doing just as much work as the original devs did...

thanks in advance for keeping this kickass filter alive and kicking

I just had a similar problem on one PC with several Windows 2000 installations per multi-boot menu. Practically all the same installations (same OS version and update level, same driver versions, just different purpose, different applications running).

On one system, ffdshow worked fine, I could slide the gamma level and everything else (only XSharpen crashed ffdshow and the player).

On another system, ffdshow crashed on sliding any option in the picture properties immediately. This was solved after uinstalling ffdshow, manually looking for registry entries containing "ffdshow" and deleting them, and reinstalling.

This solved it in my case; I woudn't guarantee that in any case, though.

[yaz]

i don't know where to post this, so i try here. feel free to transport my quests to the proper thread if i was wrong.

- i used makeavis coming with ffdshow for awhile so as to serve my avs scripts to some encoders (like mencoder) not accepting script files directly. afais in the new releases, the pack is rearranged to a certain extent. after installing ffvfw i don't find ffvfw.dll anymore. the vidc.avis entry is also missing from the registry.
the problem here is that mencoder whines for ffvfw.dll on feeding the fake avi. (or simply crashes, as there's no decoder found) i know, this dll is set in mencoder's config file, so i would change it easily to the proper value ... if i knew what's that. so, how should i do such kinda script-serving with the newest releases ?
- i tred ffvfw for encoding some test stuff. with the gui implemented it's quite easy & straightforward. my only problem was (so far) with setting the max.bitrate. it seems as if ffvfw wouldn't accept it. it's set to 10000 by def but if i change it to any other value it flips to 1000 & no way to change it. is it just a fake option or am i doing sg wrong ?

thx (& sorry if i'm at wrong place)
y

[celtic_druid]

Use ffdshow.ax instead of ffvfw.dll.

videocodec makeavis
info "FFdshow makeavis"
status untested
fourcc AVIS
driver vfw
dll ffdshow.ax
out YV12

[yaz]

@celtic_druid
thx alot !!! afais, it's the mencoder codec.conf file, isn't it.
hmmm ... should i set 'out' to yv12 (should i set it at all) ? if yes, should i always convert only(!) to yv12. (i got some scripts working in yuy2)
thx again
y
[EDIT] & how can i 'register' the 'avis decoder' ? gspot says, no proper decoder installed. i don't find the vidc.avis entry. should i set/change it also to ffdshow.ax?

[dimzon]

Hi
look at this post:
http://forum.doom9.org/showthread.php?s=&postid=471101#post471101

seem like there are some performance slowdown when using XviD 1.0 to decode (in comparision with native XviD Directshow Decoder)

I dont actually code this filter, so I'll just hope that some other user will supply you with a workaround, or maybe milan or Andy2222 can find a solution.

My contribution to this project is mainly just compiling the sources and making them available online. I do fiddle around some with the compiler flags, and small temporary modification like the OM bug, or the installer problem with long filenames.

My additions to the actual source are very few. I did add a small workaround for a bug some time ago, and this bug was soon fixed properly by milan. I also suggested a framerate doubling feature, along with a very simple algorithm for implementing it. Milan implemented this with some cool mmx assembler, and later added a much better, and more functional version of this which uses motion estimation. These can be found under the deinterlace section in the configuration.

So, I dont feel that I am really warranted to be in the About box, because I just compile the stuff that milan (mostly) writes. Anyone, who has set up their build environment with MingW, DirectX SDK etc could do this.

i think thats the same bug (compiler problem) wich cause the "gain" crash in that tab. Im on that one and might have a solution soon.

[celtic_druid]

That was just have the original ffvfw config was setup. It is going to end up YV12 anyway. That is assuming you are going for DVD, MPEG4, etc.

Doubt it matters if you have anything registered or not for mencoder.

Hmmm, dusted off GSpot and it says that same for me, but the AVI's playback fine both via VFW and dshow.

Let me be more precise. The problem is with actual framerate of the output.m2v file, not encoding speed.

I have found in the registry in the gnu/ffdshow_enc
a key: fpsOverride1000=dword:000061a8(25000)
and: fpsOverride1000=dword:000061a8(25000)

I remove these, and they combeback, so I select "don't save settings to registry" but still output.m2v is 25fps
I have tried older builds and it is still happening.
Again, it only happens on the "mpeg2" encoder. Using the "mpeg2enc mpeg2" i can set the frame rate output and it works but I can't set can't set a custom matrix, much slower, some quality settings not there.

Anyone?

Originally posted by celtic_druid

I ccannot believe this filter is taking so long to get a proper release. So many bugs to fix I guess and not enough time from the programmers. Sigh...

you're kidding right? you MUST realize these guys are working on this filter in their spare time.

as a side note, there could be more programmers available if the new source re-appeared on sourceforge. i kinda figured that was the whole idea of gpl-ing the source to begin with, so others can pick it up and run with it, just as these fine coders have done.

c'mon guys, put that source out there. you may even be able to get the original ffdshow author (or some of the higher ups of the original group) to give you rights to the original ffdshow area. it only makes sense that it goes there. not to mention a MUCH better bug tracking system than what is currently being used (this one thread, ugh).

?:| The source is in CVS right here (http://sourceforge.net/cvs/?group_id=53761).

[MfA]

Radical, well the development process of ffdshow is a bit curious to say the least so you can forgive him for thinking Athos is just working from some old version and updating it.

allynm, what happened for some reason is that somewhere along the line Milan stopped having any interest in maintaining the website or building releases ... he is still steadily coding though, you just have to build from cvs. Which athos is doing.

[allynm]

Sweetness! sorry, i was blindly going off of the old project page (the one thats a year old). i wrongly assumed that since the project page was outdated, the cvs would be as well...

[athos]

1. The source is on sourceforge. That's where I download it from for every build. See RadicalEd's post above.
2. The "group" is really Milan Cutka. There have been others helping out, but I would not really call it a group.

I just realised that both these points have allready been made. I have the impression that Milan is mostly interested in adding new features to ffdshow. I think he is doing a great job, but I do agree that there are a lot of bugs that need to be fixed. So I suggest that we try to find solutions and workarounds for the bugs, like the OM bug, the installer path bug etc, and then present them to Milan.

[zettai]

To return to a previous inquiry if no-one minds... upon further testing it appears that

[HKEY_CURRENT_USER\SOFTWARE\GNU\ffdshow]
"raw_rawv"="1"
[HKEY_CURRENT_USER\SOFTWARE\GNU\ffdshow\default]
"outYV12"="1"

Isn't enough to enable YV12 decoding if registered directly after the regular installation. There must be some other reg entries that are required to make it work but in comparing the reg entries when selecting the option so many get added that I've no idea which does what.

I've tried adding similar rawv settings in the HKLM registries as well, to no avail. Any more ideas?

ok, something to add here, and its weird.
i have found that on the picture properties tab, changing both 'luminance offset' and 'gamma correction' at the same time cause the crash (if one is moved from default but the other isnt, there is no crash).
now for the weird part: i can modify only 'luminance offset' in 'picture properties', and then i can go and modify 'gamma correction', but i do it under 'levels' instead, and it works!
this seems very odd, as the 'gamma correction' feature should work exactly the same under both tabs. it just doesnt like doing both simultaneously on the 'picture properties' tab...
...see? really weird

also, i've eliminated other causes by doing this under my clean install (which has never seen any older versions of ffdshow, and had no ffdshow entries prior to installing the 0405 build.

[dvdmonger]

Well I seem to experiencing one of those "ati issues". I installed ffdshow-20040405, and whenever I try to play any kind of divx3/4/5/xvid file, the cpu usage goes to 100%. I was using media player classic to playback the avi's. I also tried mplayer2, same result. I even tried using virtualdub, and using the vfw interface of ffdshow to decode. That seemed to be the best, with about 60% cpu usage. But that was still waaay more than what it should be. Also in virtualdub, the playback was still jerky, which is the same way it was when it was using directshow at 100%. Very odd. I'd debug it myself, but my skills are rather limited unfortunately.

I'm running xp pro sp1
athlon 750mhz
384mb pc100
MSI K7PRO
ati all-in-wonder 128 16MB agp

P.S. I am not using any postprocessing. I am using the fastest settings possible, simple idct, etc...

[LigH]

750 MHz is indeed not much, maximum resolution for full Post-Processing for my Duron 800 is ~ 512x288, bigger videos shall not use full PP on my PC (automatic level, maybe).

Also I wonder if there are any hints available which PP option consumes how much processing power - especially a comparison between MPlayer, Nics, and SPP: the last one appears very heavy to me.

milan, if you are reading this can you plz also have a look at the mpg splitters from mainconcept and moonlight (their encoders output .mpg files), their splitters are available for free, would be great if ffdshow could also connect to them!

edit: these two splitter also allow parsing of plain h.264 bitstreams (.264) as outputted by the reference encoder for example
would be great if we could use ffdshow to decode these too

[TheShadowRunner]

About Quicktime SVQ3, it's still broken in Athos' latest build :
ffdshow-20040405.exe
The problem is ffdshow crashes the player (whatever it is, ZP, WMP6.4, etc..) with an error in "libavcodec.dll"
The last ffdshow version to work ok with SVQ3 is ffdshow-20040312.exe

For exemple this spiderman trailer in SVQ3 works perfect with 0312, but not with 0405. (video only since audio is qdesign)
