Altough I'm a programming noob i tried a few weeks ago to write some code to accomplish this with (not much) but still a little succes: i used code from a program like vidcat to read a frame from my v4l device (in png format), used code from another program (png2bmp) to turn it into a bitmap, and used CreateWindowEx to display this in a windowsprogram under wine. Although the window with the frame from my webcam showed up , the windowsprogram did not behave further as it should do. There is plenty of code to be found on the internet using the v4l api, but the problem how to get this in wine. Maybe someone has some further hints?

Problem with builtin and native regedit
by Christian Costa 05 Jan '05

05 Jan '05

Hi, When I try to renamed a key with the builtin regedit, all subkeys are lost. The problem is in regedit because the native one works. The latter however crash just after the renaming. See below for the backtrace. Any idea ?

Trying to get rid of gdi.h
by Rémi Assailly 05 Jan '05

05 Jan '05

Hi all ! This mail is a resent because I noticed that it does not appear in wine-devel... I started a work to get rid of GDI_GetObjPtr and GDI_ReleaseObj in x11drv but I am not sure if have chosen a good way. This patch is incomplete : some GDI_* are still staying, those that cannot be removed using my way. Working on it I noticed something which can be interesting : graphics are faster because some times GDI_GetObjPtr were called twice and in my patch only once. I would some comments on this work.

The idea is to use the video4linux interface to implement the VFW API in Wine. The way I usually go about this kind of thing is to write a program or find a simple program (hopefully one with source code) that can grab a picture from a WebCam on Linux. Then run it in Wine, and see which error messages come out... then you'll have a starting point. Looks like there's souce for a simple program like that here: http://www.experts-exchange.com/Programming/Programming_Languages/Cplusplus… and documentation for VFW here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/h… Mike

Fwd: wineserver: fix get_update_region for desktop window
by Michael Jung 05 Jan '05

05 Jan '05

Alexandre, could you please give a short comment on this one? Thanks, Michael ---------- Forwarded Message ---------- Subject: wineserver: fix get_update_region for desktop window Date: Wednesday 05 January 2005 00:36 From: Michael Jung <mjung(a)iss.tu-darmstadt.de> To: wine-devel(a)winehq.org Cc: wine-patches(a)winehq.org Calling SetSysColor in the current cvs version of wine causes an infinite loop in update_now in dlls/user/painting.c. As I understand it, the problem is the following: get_update_flags will promote it's child window argument to the next child window (via a wineserver call to get_update_region), if the current child doesn't need any repaint. Calling get_update_flags on the desktop window will always return a repaint flag, so it never gets ahead. The attached patch automatically promotes the child window argument to the first child, if called on the desktop window. I don't know if this really is the desired behaviour. Another fix would be to not return any repaint flags for the desktop window. Ciao, Michael -------------------------------------------------------

As an application to test this stuff with I went for MSN 6.2, though certainly not the best application for this, it seemed neat to finally have Webcam support on MSN - I eventually got some of it working with a load of native DLLs, some hacking on the SSL stuff (I ended up simply setting useSSL = false, the applica- tion was sending plain-text over an SSL socket, which wasn't working; this fixed things, or at least for this application ;-)) and adding some undocumented flag to InternetSetOption (optionId = 87) - anyway, it seems that MSN is using some- thing along the lines of the following webcam class I found using Google - indeed, using a DirectShow filter: http://www.jolash.com/projects/other_projects/webcam/WebCam.h For things to start working under Wine I used the following native DLLs, which I also registered with regsvr32 (for CLSIDs etc.) COMCTL32.DLL urlmon.dll CRYPT32.DLL MSOSS.DLL oleaut32.dll ole32.dll rpcrt4.dll MSVCRT.DLL shlwapi.dll shdocvw.dll MLANG.DLL qcap.dll amstream.dll Though I'm not sure if amstream is needed. Don't know what qcap does as I only managed to get to a point where something in qcap was called which was then being forwarded to Quartz (IAMStreamConfig, for which I added a bunch of stubs and semi-stubs (filled in some bogus information for VIDEO_STREAM_CONFIG_CAPS, VIDEOINFOHEADER and AM_MEDIA_TYPE) It turned out that, at least MSN, and this webcam class too, uses devenum to find the video input devices (CLSID_VideoInputDeviceCategory), for which I've added the proper code to CreateSpecialCategories and hence CreateClassEnumerator (it also seems that the windows DLL of devenum always recreates the dynamic registery entries whereas Wine only seems to add them once and then never again, that is, once they're in the registry they stay there (hence if a new audio card gets added to the system ..)) The Windows DLL seemed to be using avicap32 to collect information on the available video input devices, so I've simply had capGetDriverDescription return some string with a fictional video driver (this also makes it possible to use a native devenum.dll) Next up is Quartz, which seemed to want IAMStreamConfig (collecting information on the video stream (res, depth, sps, ..) for starters, but I never got around to implementing enough of that for the program to accept it and move on, so that's where I got stuck. It may also have had something to do with MSN wanting an IKsPin which isn't imple- mented (which is why native quartz may have failed, when trying to approach the kernel in some way) Here's a small scenario of what I observed working with both native and hacked up DLLs ;-) DEVENUM - Read all VideoInputDeviceRenderer's (from CLSID) DEVENUM - BindToObject() --> VfwCapture QCAP - BindToClass --> Quartz(VideoRenderer) QUARTZ - VideoRenderer_create QUARTZ - [FAIL] InputPin_QueryInterface (IKsPin) QUARTS - VideoRenderer_QueryInterface (IAMStreamConfig) Anyway, the 'patches' I wrote are probably not worth much as the whole under- taking was more of a little endeavor trying to see how far I go (MSN actually managed to sign in, by the way, but kept crashing a few seconds after that (the webcam stuff can be accessed without signing in though, there's a preview option in one of the menus), but perhaps this brief explanation of my steps will prove useful for someone wanting to implement this aspect of VFW :-) Perhaps someone could build a control from the class I mentioned earlier which can then be used for testing (through the webpage that refers to it says it's missing some code; but at least it's a starting point) Jasper

[QUARTZ] Fixes to regsvr.c (RESEND)
by Paul Vriens 05 Jan '05

05 Jan '05

Hi, the Media Types (and Media Type Extensions) use "Source Filter" instead of "File Source" in the registry. There were also some small typos. I will continue with changes to regsvr.c. My first goal is to have the native quartz running with the builtin registration ! Changelog: - Media Types (and Extensions) should use "Source Filter" instead of "File Source" - Removed filesource_valuename - Fixed typo for some class-names - Fixed typo in MPEG1System Media Type Cheers, Paul Vriens.

Hi all I started a work to get rid of GDI_GetObjPtr and GDI_ReleaseObj in x11drv but I am absolutely not sure if I have chosen a good way. What I send you is incomplete : some GDI_* are still staying and we cannot get rid of those functions using my way. After getting rid of GDI_* we'll be able to get rid of BITMAPOBJ* and PALETTEOBJ* using opaque pointers as Alexandre told me. Rémi
