Installation with Gradle

build.gradle

allprojects {
	repositories {
		maven { url 'https://jitpack.io' }
	}
}

dependencies {
	implementation 'com.github.yylive.YYEVA-Android:yyeva:1.0.17'
}
// 2.0.0-beta
dependencies {
    implementation 'com.github.yylive.YYEVA-Android:yyeva:2.0.0-beta'
}

Animation with Key

For SurfaceView can use EvaAnimView，For TextureView can useEvaAnimViewV3，demo show use EvaAnimViewV3

change property interface

interface IEvaFetchResource {
    // 获取图片 (暂时不支持Bitmap.Config.ALPHA_8 主要是因为一些机型opengl兼容问题)
    fun setImage(resource: EvaResource, result:(Bitmap?) -> Unit)

    // 获取文字
    fun setText(resource: EvaResource, result:(String?) -> Unit)

    // 资源释放通知
    fun releaseSrc(resources: List<EvaResource>)
}

You can find the example int the project in app module.

Play with IEvaAnimView interface.

interface IEvaAnimView {
    ...
    //播放文件
    fun startPlay(file: File)
    //播放本地文件
    fun startPlay(assetManager: AssetManager, assetsPath: String)
    //停止播放
    fun stopPlay()
    //是否正在运行
    fun isRunning(): Boolean
    //循环播放
    fun setLoop(playLoop: Int)
     //设置背景图
    fun setBgImage(bg: Bitmap)
    //speed为倍速
    fun setVideoFps(fps: Int, speed: Float = 1.0f)
    //设置资源颜色区域和透明区域的对齐方式
    /*
    const val VIDEO_MODE_SPLIT_HORIZONTAL = 1 // 视频左右对齐（alpha左\rgb右）
    const val VIDEO_MODE_SPLIT_VERTICAL = 2 // 视频上下对齐（alpha上\rgb下）
    const val VIDEO_MODE_SPLIT_HORIZONTAL_REVERSE = 3 // 视频左右对齐（rgb左\alpha右）
    const val VIDEO_MODE_SPLIT_VERTICAL_REVERSE = 4 // 视频上下对齐（rgb上\alpha下）
    const val YYEVAColorRegion_AlphaMP4_alphaHalfRightTop = 5 // 视频上下对齐（rgb上\alpha下）1/4 elpha
     */
    fun setVideoMode(mode: Int)
    //设置起始播放位置 毫秒
    //硬解某些机型会有跳帧前几帧解析异常的问题，不建议使用。
    fun setStartPoint(startPoint: Long)
    //设置静音
    fun setMute(isMute: Boolean)
    //是否不透明度mp4
    fun setNormalMp4(isNormalMp4: Boolean)
    //是否停留在最后一帧
    fun setLastFrame(isSetLastFrame: Boolean)
    //设置日志打印
    fun setLog(log: IELog)
    ...
}

2.0.0-beta use OptionParams to set

class OptionParams {
    var frameRate = 30
    var playCount = 1
    var isMute = false
    var isRemoteService = true  //使用多进程
    var mp4Address = ""
    var scaleType = 1   // 1=>裁剪居中， 2=>全屏拉伸  3=>原资源大小
    var filterType = "" //高清算法 hermite lagrange
}
