Usages

 AUSBC 3.0 was refactored by kotlin and It is simpler to use and more feature-rich. So, I highly recommend you to use the current version and let's build it together.

• Get AUSBC

 First, add it in your root build.gradle or settings.gradle at the end of repositories:

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

 Second, add the dependency in your app.gradle , latest tag is :

dependencies {
    implementation 'com.github.jiangdongguo.AndroidUSBCamera:libausbc:latest_tag'
}

• Simply usage

  As for how to use this module correctly, just making your Fragment or Activity implement CameraFragment or CameraActivity.

…

 The most important is that you should override getRootView()/getCameraViewContainer()/ getCameraView() at least which means fragment's root view 、texture or surface view and it's container。Of course, the same as CameraActivity and now you can see the uvc camera preview。

• Advanced usage

 If you want some custom configurations, you can do like this in your DemoFragment:

…

 Of course, you can also capture a jpg image or a mp4 video or a mp3 audio file and update resolution or different uvc camera and acquring the stream of H264/AAC/YUV/PCM by calling those method:

…

 Or, camera configuration:

setZoom(0)
setSharpness(0)
setHue(0)
setSaturation(0)
setContrast(0)
setGamma(0)
setGain(0)
setAutoWhiteBalance(true)
setAutoFocus(true)
// send custom command to camera
sendCameraCommand(command)

 For more advanced features, you can even add some filters to your camera.This library providers some default filters, sush as EffectBlackWhite、EffectSoul and EffectZoom, and more filters will be added in the future.Of coure, you can also relize your own filters by extending AbstractEffect. For example：

// First, extending AbstractEffect
class EffectBlackWhite(ctx: Context) : AbstractEffect(ctx) {

    override fun getId(): Int = ID

    override fun getClassifyId(): Int = CameraEffect.CLASSIFY_ID_FILTER

    override fun getVertexSourceId(): Int = R.raw.base_vertex

    override fun getFragmentSourceId(): Int = R.raw.effect_blackw_fragment

    companion object {
        const val ID = 100
    }
}

// Second, adding or updating or removing filter
addRenderEffect(effect)
removeRenderEffect(effect)
updateRenderEffect(classifyId, effect)

 At last, If you want to realize streaming, maybe IPusher and AusbcPusher can help you.

• open multi-road camera

 If you want to open multi-road camera, you can make your Fragment or Activity extend MultiCameraFragment or MultiCameraActivity.Just do like this and more details please look up DemoMultiCameraFragment：

…

• Debug online

 If you want to debug the project online or modify something, those steps you should do:

 First, modifying the Settings.gradle file and making those to module.

include ':app'

// For debug online
include ':libausbc'
include ':libuvc'
include ':libnative'
include ':libuvccommon'

 Second, let app.gradle dependenced on ':libausbc' .

dependencies {

    // For debug online
    implementation project(':libausbc')

    // demo
    //implementation 'com.github.jiangdongguo.AndroidUSBCamera:libausbc:latest_tag'
}
