eduramiba / webcam-capture-driver-native Goto Github PK

I'm new to both of these libraries, but when I try to use WebcamDiscovery it fails due to the driver not implementing WebcamDiscoverySupport

Hey @eduramiba, thanks much for this! Any chance of getting artifacts published to maven central? We're using the drivers in Sparkle Motion. Thanks!

I'm getting issue with this library, the webcam is not opening nor I see any preview on the UI. Below are the debug logs.

I can't open 6 webcam with same pid and device id.
The last 3 webcam will never return an immage but correctly open...

Could you help me?

Solved : Not enough bandwidth on usb 3.0

See:

• sarxos/webcam-capture#888
• sarxos/webcam-capture#889

This is an upstream issue, but I thought it would be helpful to note it here. (We should push for sarxos/webcam-capture#888 upstream and/or create a fork)

on macOS Mojave, Mac M1, running the sample app using the built-in FaceTime camera:

name='FaceTime HD Camera', resolutions=[java.awt.Dimension[width=1920,height=1080], java.awt.Dimension[width=1280,height=720], java.awt.Dimension[width=1080,height=1920], java.awt.Dimension[width=1760,height=1328], java.awt.Dimension[width=640,height=480], java.awt.Dimension[width=1328,height=1760], java.awt.Dimension[width=1552,height=1552]

I'm seeing the following resolutions display "diagonal-striped" video:

• [width=1080,height=1920]
• [width=1328,height=1760]
• [width=1552,height=1552]

It seems all the cases where height >= width, but I don't know if this is the actual cause.

The following workaround was used because the default size was failing:

        final Dimension dimension = new Dimension( 1920, 1080);
        device.setResolution(dimension);

Java 21
IntelliJ IDEA 2023.2.5
com.github.sarxos:webcam-capture:0.3.12
this library v1.0.0

README documentation does not mention modules. Workaround is to add requires io.github.eduramiba.webcamcapture;

Running the application as recommended, I get

14:38:26.220 [main] DEBUG com.github.sarxos.webcam.Webcam - Setting new capture driver com.github.eduramiba.webcamcapture.drivers.NativeDriver@4e096385

14:38:26.241 [main] INFO  c.g.s.webcam.WebcamDiscoveryService - Discovery will not run - driver NativeDriver does not support this feature

I believe it's looking in the wrong place for the native driver.

It would be nice if this could be split into 3 JARs:

1. A standalone JAR for the macOS driver
2. A standalone JAR for the Windows driver
3. A combined (either merged or using transitive dependencies) JAR that contains the combined NativeDriver class and behaves the same as the current JAR.

This will reduce the size of the JARs and their dependencies for apps that don't need everything.

I also think the JavaFX dependency should probably be removed.

It would be good to see Libgdx support with direct opengl textures and LibGDX Textures for performance.
We can also use opengl shaders directly to webcam with that.

Some people prefer JOGL.
I had example for that i will post you if you want.

Hello! I have a question, not an issue. It works fine on my Mac, but can't find any webcams on Windows 11 laptop or desktop
What am I doing wrong?

I have integrated this in Windows and Mac.

In Mac it is working perfect.
In Windows, First time when we open, it is streaming. If I close and reopen, it is not straming and displaying previously captured pic.

If open the webcam in async mode it will no wait untill a new photo is grabbed but give you back a blank image instead of waiting...

After having close and open a webcam is not possible to open anymore!

This is the code :
`
Webcam.setDriver(new CaptureManagerDriver());
Webcam webcam = Webcam.getWebcams().get(4);

    long t1, t2;

    for (int i = 0; i < 5; i++) {

        try {
            System.out.format("Opening...\n");

            t1 = System.currentTimeMillis();
            webcam.open();
            t2 = System.currentTimeMillis();

            System.out.format("Opening time: %d ms\n", t2 - t1);
            System.out.format("Fetch image...\n");

            t1 = System.currentTimeMillis();
            if (webcam.getImage() == null) {
                System.err.println("Damn! Image is null!");
            }
            t2 = System.currentTimeMillis();

            System.out.format("Fetch image time: %d ms\n", t2 - t1);
            System.out.format("Closing...\n");

            t1 = System.currentTimeMillis();
            webcam.close();
            t2 = System.currentTimeMillis();

            System.out.format("Closing time: %d ms\n", t2 - t1);
            System.out.format("Wait 5 seconds...\n", t2 - t1);

            Thread.sleep(5000);
        } catch (InterruptedException ex) {
            java.util.logging.Logger.getLogger(Main.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
    }

    System.out.format("Done...\n");

Without the loading of the driver

Hello,

I am currently facing a challenge with the webcam-capture-driver-native library in my project where I have connected 3 identical webcams (Hikvision DS-U02) to my computer. These webcams are identified by non-unique names by the library. This issue prevents me from distinguishing between these cameras and working with them individually to capture video streams simultaneously.

Here is an example of how the camera names are detected by the library:

• 1080P USB Camera
• 1080P USB Camera
• 1080P USB Camera
• HD-камера FaceTime

The three "1080P USB Camera" entries correspond to the Hikvision DS-U02 webcams. Their identical names make it impossible to select and use each webcam independently, which is crucial for my application.

This issue arises from the use of the library with the com.github.sarxos.webcam package, specifically when trying to lock a webcam for exclusive access (WebcamLock.class)
The non-unique names cause conflicts in the locking mechanism, preventing simultaneous use of the cameras.

Suggested Feature / Fix:
It would be highly beneficial if the library could provide a way to generate unique identifiers for each webcam, possibly incorporating attributes such as connection port or an internal index. This would allow applications to distinguish between multiple webcams with otherwise identical names.

Environment:

• Operating System: macOS with M1 Processor
• Library version: 1.0.0
• Java version: 20.0.1 (OpenJDK)

The WebcamDevice#getImage method is implemented inconsistently compared to the built-in WebcamDefaultDevice, which returns a new BufferedImage object. This inconsistency currently results in the WebcamPanel not executing repaintPanel().

This line always evaluates to true. https://github.com/sarxos/webcam-capture/blob/fdfcaea80c8f50eeb8f7c24475ff85a3c1fdcb32/webcam-capture/src/main/java/com/github/sarxos/webcam/WebcamPanel.java#L603

First of all great library.

I've problem open multiple webcam. Untill 2 webcam everythings is fine... i need to open 6.
Error is the following :

Exception in thread "main" com.github.sarxos.webcam.WebcamLockException: Webcam USB has already been locked

When no use your driver everythings is working well...

Any ideas?
