@All: New Version: Capture!.zip

Watch out: If you chance the audio or video device, you have to re-select the video and audio properties!! Becaus switching the audio or video device causes a reset of the capture-object, setting it back to the defaults.

The error displayed when changing the audio-settings (sample rate, 8/16 bit) is now gone. You can save the audio-settings to the config.ini now correctly.

The window behaves now not as "always on top". The ontop function is now only called once while starting up, so the window is displayed and not hidden behind another window.

@Bodgy: that function was not implemented in the DXCapture tool. I removed it from the menu. But you can set the input source via the "Property Pages - Audio Capture Device", or via the windows sound-mixer.

@tj!2k4: i tested the original app and my modification without any video capture device attached to the computer. i get an error like yours when starting up the tools. Please test with the attached capturetest tool and tell me if you get the same error. If yes, your camera will probably not register itself as a normal WDM capture device in the system.

Thanks for the info..

Here's the error that I get when trying to select the 3Com Homeconnect cam.. is there any way you might be able to add support for such devices, if I send you the driver or such?

Thanks..

Thanks for testing! I do not develop the DXCapture Class i use to access the video devices. So i cannot ad support for new devices, sorry :-/

The Capture! tool should work with all regular windows WDM capture devices (tv-cards, vivo-graphiccards and webcams). It works fine with 3 different webcams i tryed and my ati X800 card wich has video-input. So if your webcam does not work, there might be a compatibility issue with the drivers that came with the cam. Have you downloaded the newest version?

Sorry I can't help on this... :-/

I had a similiar problem. Deleted the config.ini from the Capture! directory, ran my own capture proggy to make sure the camera was working, then ran capture! prog and all was well.

Prefect · 09-18-2005, 10:19 AM

Thanks GizmoQ. The Error will be shown, if the default values from the config.ini won't match with your camera (device id 0, resolution, framerate etc..)

these are the default values if you delete the config.ini: (last parameter...)

("CaptureDeviceConfig","VideoInputDevice", 0);
("CaptureDeviceConfig","VideoCompressor", 2);
("CaptureDeviceConfig","FrameRate", 30);
("CaptureDeviceConfig","FrameSizeWidth", 320);
("CaptureDeviceConfig","FrameSizeHeight", 240);

("AudioDeviceConfig","AudioInputDevice", -1);
("AudioDeviceConfig","AudioCompressor", 0);
("AudioDeviceConfig","AudioSamplingRate", 44100);
("AudioDeviceConfig","AudioSampleSize", 16);
("AudioDeviceConfig","AudioChannels", 1);

("MiscConfing","SaveToDrive ", "C:");
("MiscConfing","SaveToPath", "\\");
("MiscConfing","VideoFileName", "CarPC");
("MiscConfing","AutostartCapture", 0);
("MiscConfing","StopAfterMB", 0);
("MiscConfing","StartOver", 0);
("MiscConfing","WindowStateOnLoad", "normal");

New Version: Capture!.zip

Added Try-Catch to display errors while starting up. Now the app will not close itself if something goes wrong while trying to setup the camera. So you can try switching the device and save the config.

Sorry, I didn't quite understand how to run multiple cameras, can you explain it a bit more simple?

thanks

Prefect · 09-19-2005, 08:18 AM

@Go-carter: "multiple cameras" are not supported directly. Caputre! can only record from one camera at once.

If you have two cameras (front and rear or so), you can copy the whole app to two different folders, say
c:\program files\capture_front and
c:\program files\capture_rear.

configure the two config.inis to your cameras (in capture_front\config.ini set "VideoInputDevice=0" and in capture_rear\config.ini set "VideoInputDevice=1").

Now you can make shortcuts to the two versions or add both in ces or cpos or whatever.

Make sure that only one instance of Capture! runns at a time!

I tried to access two cameras at once in another app, but the VIA C3 System was not fast enough for that...

Go-carter · 09-19-2005, 08:50 AM

I found it out, thanks

I'm going to record both forward and the driver

(sry for bad english...)

Tone · 09-23-2005, 02:46 AM

i just downloaded the capture program and tested it on my laptop befor i put it on my carputer and all works well exept 2 things...

when imbedded in centrafuse the preview screen streches the preview... rather than keeping the preview square (the actuall recording is fine)

the second thing is when i hit start i get this...

i lose my preview and get a blue section insted.... is this suposed to happen?

thanks for any help...

Prefect · 09-23-2005, 06:18 AM

Hi Tone!

That's all correct, and not a bug but a feature!

The "bluescreen" is the background image. You can put your own image there by replacing the "backround.bmp" with any bmp you want. (i have a picture of my car there)

The reason for this is, that the VIA C3 System is not fast enough to record AND display a preview video.

For the aspect ratio thing i could include a new config.ini value "WindowWidth" and "WindowHeight" so you can set your own window size if running in "WindowStateOnLoad = normal". Would that solve your Problem?

My goal was to maximize the size of the preview window, regardless of the aspect ratio.

Cris · 09-23-2005, 06:41 AM

So this doesn't work on a Via?

Prefect · 09-23-2005, 07:01 AM

Sure! The app is designed for a Via EPIA C3 System!

Without the preview-window active while recording the C3 1GHz System is able to record at 320x240 with 30 fps and divx 5.2 compression and audio recording with mp3 compression while having CES playing mp3s and navigating with travelbook.

It works very well, except that starting the app is a bit slow and after you pressed "start" the status display takes some seconds to show up, but recording is immediately.

Cris · 09-25-2005, 09:29 AM

I'm not sure it has anything to do with the program, but after I record something, and open the video file just captured, the file doesn't play. It says playing, but nothing on the screen...any ideeas?

Prefect · 09-25-2005, 09:52 AM

@Cris: try deactivating the video codec and sound recording, change resolution and framerate, then try again. copy the video file to another computer and see if it plays there.

what error message do you get when you doubleclick the recorded avi?

Greetz, Chris

Thanks Chris. I've tryed all that, except copying the file to another computer.
I don't get any error massage, just media player doesn't play the file. It says it's playing but the bar isn't moving. Sorry about the off topic, as I don't think it's related to your software. Could be my lousy camera...I'll test it in the car when the new cam arrives.
