ReClock DirectShow filter : try it !

[ogo]

ffdshow gives me purple colors with clip2. clip1 seemed ok

no problems with divx 5.0.3 pro + reclock with both clips in whatever player i tried (MPC, ZP, WMP) ...

hope this helps !

[ogo]

Hi,

The next version of ReClock (0.99h, and still some room until Z :)) is available on my website.

It has some interesting new features ...

@kallekill : and it corrects your problem

OGO

[kallekill]

I'm sorry to say it but I still got desyncted refreshrate, even if I enable the VSYNC monitor and run a clip that Reclock can sync the refreshrate to. I have a short clip that falls out of sync every time at a certain point. Ogo, I can send the clip to you so that you see what I mean. By the way, Media Player 6.4 doesn't like the VSYNC monitor at all. It crashes when opening a movie.

[ogo]

That's why i said it's experimental :D

Yes please send me your clip !

Hi there!

Great work with the VSync monitor...it works fine here with my G400 DH card, no vsync problems! [See UPDATE below, might have a few still]

But what I still don't get is how I can use that to determine, if my video playback on the TV is jerky (well, kind of micro-jerky, to the naked eye it's fine)...in my video window on the monitor the vsync dots stay close together as they should and the bar doesn't move too much [UPDATE not always, sometimes I have the bar moving around a bit and then go steady again for some time]...so fine so good...this image is sent to the TV and of course the bar and dots is exactly the same on the TV, but it's a copy of the monitor image...couldn't it still be, that the TV VSync is another than the monitor refresh rate? Or does that thing in the readme apply, that the TV adjust itself automatically to the VSync in a certain limited range...and apart from that, we still don't know, if the G400 internally syncs it's TV-clock to the (perfectly adjusted (thanx to Reclock)) monitor-clock...or did I miss something? I can tell you now, that ReClock syncs fine on my monitor...can I conclude somehow it also syncs fine on the TV on my card? If yes, how?

[Dr_Colossus]

I have a clip that doesn't play very well at all with the new version but plays fine with the old version, I tried remuxing it with avimux but I still get pauses. Here's a link to the clip (http://www.enel.ucalgary.ca/~brooks/clip.avi). This happens in any mode I choose.

[ogo]

@Dr_Colossus : you're right there is something wrong with this clip. I'll have a look into that and let you know. Thanks for your report. Please keep the file available a few days.

@Chibi Jasmin : i'm nearly sure the tv clock is the same as the clock used by the ramdac. To answer this question, i should add something like a "tearing test" into vsync monitor : in this test, i could display a fast continuous moving vertical bar across the video. If a different clock is used to display picture on tv, then you should see some tearing (the bar would be broken somewhere) because i believe parts of 2 frames would be displayed on the same time, or jerky movement of the bar.

@kallekill : I've not been able to crash WMP 6.4 with the vsync monitor. What OS/video card do you use ?

Anyway, as blight told me, new beta 6 of ZoomPlayer have an audio stream switcher that should work with reclock :D

[cult]

Ogo may I make a suggestion?Could you please place your site in your signature?

[Ewi]

But although the Vsync Bar is Jumping around with VMR9, the playback is much smoother for me under VMR 9 compared to VMR7. I tested it with Sumsters Godfather 3 clip (the one he posted a few weeks ago). Even if the VsyncBar is between the two limits, the height is rather small and the location of the bar is more or less stable, VMR7 is clearly disadvantaged.

MPC 6.4.3.1
WinXP
AthlonXP
Geforce2Ti

[kallekill]

I have a Geforce 4 Ti 4200 card running on Windows 2000 SP3.

Ogo, if you go online on icq I can send you the clip that always makes the picture fall out of sync at one point.

[kallekill]

MPEG1 files play just fine, but Divx-movies hangs Media Player 6.4 when enabling VSYNC MONITOR.

MPEG1 files makes MP 6.4 hang too. Sometimes it just takes a few seconds.

[gabest]

ogo: There is a new build of MPC posted in its topic (v6435). I changed the vsync code of vmr7 and the rm renderer, and now the jitter tests that karl lillevood has posted to somewhere are running flawlessly.

[mazzo]

1. ReClock doesn't work with my laptop, because the LCD seems to have a refresh rate fixed to 60 Hz.

2. When using a TV as monitor, the refresh rate is lowered to 50 Hz, which should be okay, but when I enable ReClock, the video will run like h..l, almost in double speed.

Do you have any suggestions?

In its topic? Where would that be (if it's meant for the public), please?

[gabest]

Chibi Jasmin: It is under the players forum.

ogo: I've got another idea how to detect when the renderer receives a frame. Do you know delegating from .net? Why don't you hook onto IMemInputPin::Receive? Replacing function pointers is not nice, but it might just work.

[ogo]

@cult : done :)

@Chibi Jasmin: it's already done, i'll post it tonight on this URL (just for testing) : http://ogo.nerim.net/reclockfilter/setup_latest.exe

@gabest: i nearly gave up in my attempt to make the monitor work with DVD playback. Even worse some MPEG2 decoders simply refuse to connect to it because they don't know it (i suppose for anti piracy reasons). So it's not the way to go.
I thought replacing the allocator provided by the renderer by giving it mine (with NotifyAllocator), and calling back the original one, so i would be notified each time a new sample would appear. But you're idea seems much better (i could be notified AND overwrite the sample to add my little stuff). But how could i find and replace this pointer ? I can only obtain a COM interface to IMemInputPin. Overwriting the vtable ? I like that :devil:

>. ReClock doesn't work with my laptop, because the LCD seems to >have a refresh rate fixed to 60 Hz.
You have to live with it. 60 is not a good refresh rate for PAL. Just choose "refresh rate/2.5" in media adaptation.

>2. When using a TV as monitor, the refresh rate is lowered to 50 >Hz, which should be okay, but when I enable ReClock, the video will >run like h..l, almost in double speed.
Does reclock says "50hz" in the "video hardware" tab of the properties panel ? If yes what does reclock say in "media adaptation" tab ?

[Dr_Colossus]

The newest Reclock 0.99h and the newest AC3Filter 0.65b produce no sound. Reclock 0.99h + AC3Filter 0.63b = sound. Reclock 0.99g + AC3Filter 0.65b = sound. A strange bug.

[cca]

That's strange. Reclock 0.99h + AC3Filter 0.65b work just fine here. Is AC3Filter set to PCM 16 Bit output? Please check again.

[ogo]

@Gabest : Bingo ! :)
Modifying the vtable of the IMemInputPin* interface did the trick because all COM methods are virtual ! I can now intercept every call to IMemInputPin::Receive, i can even modify the sample to incrust my stuff in the frame, and detect format changes. For now i've just made an ugly prototype, but it already works fine will all the renderers and all decoders i tried (so it works with DVD). Only had problems with the internal renderer of BSPlayer (seems like i don't replace the good vtable entry).

And all of this with only 20 lines of code. It involve some patching directly in the code space using WriteProcessMemory(). Hope it will work fine on win98 :)

Me happy

I tested it! Man, this is perfect!

The tearing bar does not break up, not on monitor and not on TV. The VSync bar stays calm, always near the little dots and between the lines! (Well, sometimes when seeking it takes a moment to find it's way back between the lines :))

If the tearing test actually is reliable (I am not the one to judge that, what do you say?), that would mean, the TV-Clock and the Monitor-Clock is the same on my card and playback is fine! Am I right?

UPDATE
Although playback is fine and tearing bar does not break, I sometimes still have the vsync bar moving across the screen...this could be due to high (not too high, it's not even close to 100%) CPU usage and the time needed to decode a frame (seems to happen with high resolutions and/or high bitrate frames)? Just a guess...it's my impression...not sure...probably it's not ReClock's fault, in general the VSync system seems to work...only question is the validity of the tearing test...

[cult]

Thx Ogo
:cool:

[ogo]

For me it's reliable, if the bar moves without stutter, and is not breaked somewhere. Happy it does work for you !

Yes it's quite sensitive to cpu load changes (scenes change for example). I have this too on my system. Thanks to the idea given by Gabest, next version of the monitor *should* be less sensitive and more precise, because it will be directly plugged inside the renderer.
I've not yet tested latest version of MPC (6435) but Gabest said he changed something in the code for vsync (maybe it's related to what i say at the end of reclock's readme).

:)

Fine! Sounds good...I will trust you on reliability then I say it works fine on my card! ReClock is just invincible!

Would be nice, if you could improve on the sensitivity issue...does the new vsync code in mpc6435 have anything to do with this? I didn't quite understand...or will all players benefit from improvements on the sensitivity thing?

BTW: It's the VSync monitor that is sensitive to cpu load changes, not ReClock's functionality itself, is that right? I was wondering, why the tearing bar didn't break, even when the VSync line was going wild...!? Is there some way to force VSync and therefore tearing issues? Maybe enable the vsync monitor for not-reclocked refresh rates? I would like to see, if it breaks up at all!? :D

OK. Works fine

Does reclock says "50hz" in the "video hardware" tab of the properties panel ?
Yes.

If yes what does reclock say in "media adaptation" tab ?
It doesn't matter. The video runs along in approx 50 fps in any case.

[ogo]

@mazzo: could you enable logging in the configuration app, then retry a video, and finally send me you log (c:\reclock_log.txt) by email ? thanks

@Chibi Jasmin:

It's not specific to mpc, all players would benefit from it.

Yes right.

I think it all depends on how the player (or the renderer) manage back buffers. If it does double-buffering, i don't think you will get tearing, but stuterring of the vertical test bar (and video too).

Is there some way to force VSync and therefore tearing issues? Maybe enable the vsync monitor for not-reclocked refresh rates? I would like to see, if it breaks up at all!?
I could enable it, yes, at least the vertical tearing test bar. Showing the vsync position in this case is not very relevant because you will only see hits randomy distributed dots on the screen (since vsync is not synced to the frame rate).

I could also use monitoring information to make reclock work when the media refresh rate could not be found, just by measuring at which rate the frames are presented to the renderer ...

[slolsby]

OGO, there seems to be some problem using Reclock with the latest version of AC3Filter, 0.66b. If I use Reclock 0.99h, I get no sound at all when AC3filter is set to SPDIF. If I use 0.99g, and an AVI with an AC3 soundtrack it fails to detect my monitor refresh rate (which is 75Mhz, ie PAL), and the tray icon is yellow (but I do get sound ok). If I use an MP3 AVI, it detects and sets to PAL mode ok. If I uninstall AC3filter and use the Intervideo filters for an AC3 AVI, Reclock correctly sets PAL mode.

Would be great if you could get Reclock and AC3filter working hand-in-hand, especially for us PAL users.

[cca]

Unfortunately I have to confirm the problems that slolsby reports. AC3Filter 0.66b with Reclock produces no sound at all! There is some problem with the cooperation of the filters. Note that I get no sound on analog modes. I did not try SPDIF.

[ogo]

Yes there are problems with version 99h and ac3filter 0.66b. Those are in fact the same problems reported by Dr_Colossus with a normal AVI file.

Version 99h check timestamps of audio samples coming from the audio decoder (for example ac3filter). If they come too late to be rendered without audio/video desync, reclock cuts sound and restart playback from that point to stay in sync (it's visible in the log). It give a short silence. The problem with ac3filter is that i get a lot of "late" samples, giving a long a constant cut/restart cycle on sound (ie complete silence). I saw that too with other audio decoders, so i'm not sure it's ac3filter fault.

I'll look at that next week cause i'm out for a few days :) In the meantime i suggest you to use an older version (99g)

Thanx for all your input! You have great ideas!

About the above quote: Would you explain the back buffering anymore? How can I verify, it it's used...? And if it's used, is there any way to check, if ReClock is working perfectly (without stutter) or will I have to rely on my eyes?

[downloada]

hi,

i have to report the exact same problem slolsby has.

on my htpc i get no sound at all using ac3filter 0.66b (spdif out) + reclock 0.99h. also, reclock fails to detect the refresh rate, the icon stays yellow. with 99g i at least get sound but the icon stays yellow, too. for the record: i use win2k sp3 on an athlon 1ghz b, a radeon 7000 and an sb live 5.1 in my htpc.

on my main-pc there aren't any problems using a similar software configuration. ac3filter 0.66b (2/0 stereo) + reclock 0.99h works just fine and detects the monitor refreshrate correctly. but i have to say that my monitor runs at 72hz (i've got a tft-display, so i can only choose between 60hz or 72hz where i think 72hz is the better choice). on this pc i also use win2k sp3 but on a p4 2,53ghz with a geforce2gts and a terratec dmx xfire 1024.

[oddball]

ReClock 66 barfs when DirectSound is enabled as the default sound renderer. The video keeps speeding up randomly for some odd reason. Once DS is turned off everything plays fine again (I use Zoom Player 3b with DirectSound sometimes to give less jerky playback of OGM with OGG audio).

[kallekill]

Reclock 0.99h has fixed the problem I had with audio falling out of sync on some mpg files.

The VSYNC monitor might have helped with making the videosync stay in sync when starting a movie and when you pause, then play. But it doesn't help when there is a slight jerk in the movie. It still goes out of sync at these points. I have found out that there is a much bigger chance that it stays in sync if you use divx 3.11 codec instead of ffdshow or if you use mediaplayer 6.4 instead of Zoomplayer. It's a petty I can't use the VSYNC monitor along with mediaplayer 6.4, but it might be because MP 6.4 has some kind of built in sync monitor.

How to set it permanently ?

[bilu]

@mmorselli

I also have a laptop, Compaq Armada M700, with TV-Out.

Refresh rates on LCD is a virtual thing because LCD's don't need to refresh, they just change the pixel. The value 60Hz only exists because Windows treats LCD's as default monitors.

I've noticed that when I activated the TV-OUT (ATI Rage Mobility P/M) on the laptop, Reclock reported a clock of 50 Hz instead of 60Hz.

I was getting frustrated before with a scan converter that I bought (Trust Televiewer) because of the 60 Hz refresh, it was connected on VGA port. Now (I haven't tested yet) it should work because I defined a profile with both TV-Out and VGA port enabled, and Reclock reports 50Hz! :D


I hope this can help if you have TV-Out on the laptop.

Hi !

Version 0.99i is available. New Vsync monitor, fix for ac3filter, and sound cutting in some files ...

ogo

[mmorselli]

@ogo

I'm sorry, but I get no sound, exactly like version 0.99h

[slolsby]

Thanks ogo - it fixes AC3 sound for me with AC3filter. However, it still fails to detect my monitor refresh rate (75mhz) and switch into PAL mode - it only fails to do this with AC3 files through AC3filter.

What would be nice is if we could have an option to set a mode (PAL or NTSC) ourselves, and have it remembered between files. I'm running a Matrox Millenium G550 dual head, where the TV out goes via the secondary connector. I would like to be able to switch between PAL or NTSC output as I choose without having to change my monitor refresh rate.

Thanks

[Ewi]

0.99i works for me, again. I have no AC3 equipment but with 0.99h i had periodically sound dropouts (0.99h was the first version, that did not work for me); around every 30 seconds. Thats gone...

But some questions:

1) Setting the system default video renderer: normally I'm using Zoomplayer. But how can I switch there to VMR9? My system default renderer is VMR7 (at least that is what Relock tells me). If I choose 'Override VMR' in Zoomplayer, Zoomplayer freezes when Reclock is activated. So how can set the system default video renderer so Zoomplayer can use it. In MPC VMR switching is working.

Zoomplayer: 2.90
MPC: 6.4.3.1
WinXP,AthlonXP

2) When I activate the Tearing test I see the vertical bar. So far so good. But the width of this bar is doubled when playback is on and it is flickering. On pause I see the normal bar with its normal width. Is this normal? Thats the same under all renderers. Apart from that I do NOT see the bar broken somewhere in two parts or jerky movement (with the default target set to have of its size); I think with jerky movement you mean stuttering of the whole bar that is clearly visible and not that what I described above what you can interpret as a kind of jerky movement (cause I think if the bar size is doubled I see 2 bars at the same time and so 2 frames at the same time? Or is this some kind of optical illusions)

3) Before I get it: Is HyperSnapDX able to capture this? If it is I would try to make a screenshot. I ask cause I heard that it is THE standard to capture all kind of DirectX screens and is used whereever a game does not support screenshots. But I'm not a great gamer...


Thank you again...

[ogo]

@mmorselli : please send me your logfile (activate it with config app, then play something, and send me c:\reclock_log.txt)

@slolsby : i don't get you at all. You can't make something round square. If reclock detects 75hz, it can NOT resync correctly a NTSC movie and vice versa. There is nothing to force here. I think you are telling me it detects the monitor refresh rate regardless tv out is activated or not. I can't nothing for this (i can't detect this). As said in the readme, reclock will detect things correctly ONLY on primary monitor. You seem to use dvdmax mode, which can't be detected. To be ok, just make sure that tvout and monitor use a same root refresh rate (eg tv at 50hz, and monitor at 50hz for PAL, and 60hz for both in NTSC). Or i did not understand you ... Just tell me :)

[ogo]

@ewi

Maybe you should try ZP beta 3. Very stable here with all the renderers, and you can choose VMR9. As said in the readme i discourage using VMR9 anyway.

2) When I activate the Tearing test I see the vertical bar. So far so good. But the width of this bar is doubled when playback is on and it is flickering.

Just optical illusion. I see two bars too :) It all depends of the framerate. Yes by jerky movement i mean stuttering of the whole bar.

Should work yes (did not try myself)

[slolsby]

Sorry, ogo, I'm not being clear.

My primary monitor refresh rate is set to 75Mhz. If I play an AVI with MP3 soundtrack, Reclock detects and set PAL mode ok (and I get the green tray icon). If I play an AVI with AC3 soundtrack (using AC3filter), it does not detect PAL mode and I get a yellow tray icon.

I can set PAL mode manually when this happens, but if I am playing a two-part movie, when it changes to the second AVI, Reclock must be set manually again to PAL mode.

For DVDMAX, it doesn't matter what the refresh rate is for the primary monitor, so it would be nice to be able to set Reclock to either be permanently in PAL or NTSC mode.
