展示解决方案只能是不使用19（COLOR_FormatYUV420Planar），21（COLOR_FormatYUV420SemiPlanar）没问题，所以我新增了一个优选列表，优先选择21 37 | 并且OMX.google.h264.encoder这个编码器在华为上也无法使用，编码的视频有问题无法播放，别的机型测了几款没问题。 38 | 39 | ## 2024/04/09 修复在Android14上的采集问题 40 | 主要是在PixelCopy.request中，不像前代api会阻塞返回了，正如之前在RecordViewUtil中134行注释中所说的，在这一代api中突然生效了 41 | 42 | 目前已知在Android7.1.1 API25上还有问题，Muxer相关 43 | 44 | 并且在非采用PixelCopy.request方案的录制中，采集摄像头View需使用TextureView，直接使用CameraX中的Texture无法采集到，会是黑屏 45 | 46 | ## Nov 23 2023 新增一个录制类 ViewRecorder 47 | **高可用，比我之前写的那个兼容性要好，暂时项目中先用这个** 48 | 不过因为也是临时用，又紧急，所以一些可配置下项我暂时还没抽出来，只根据自己项目需要写死了值 49 | 50 | 借用了pedroSG94在他的RootEncoder推流项目中的录制编码部分类进行修改 51 | 感谢大佬的开源分享，项目地址：https://github.com/pedroSG94/RootEncoder 52 | 原版本在机型兼容性上存在一些问题，由于比较紧急，暂时没时间调试，所以先在该项目基础上写一版能用的，这个项目考虑的还是比较完整的。 53 | 54 | 他的代码已经写的很好了，不过很复杂不便于学习，我足足看了两天，interface很绕，我删除了部分他推流用的功能，做了些许精简 55 | 他的项目是流，所以使用的是ArrayBlockingQueue，而我是实时采集，所以Video这部分我加了判断但还没有删除，Audio部分则是删除了。 56 | 后面有时间继续学习他的编码部分，完善下我这个简单的单纯的录屏功能 57 | 中间还参考了两个项目，一个微软的，一个chromium的 58 | https://github.com/microsoft/HydraLab/blob/b50bc6054d32a1b83d6c944ef9fbd393150922ab/android_client/app/src/main/java/com/microsoft/hydralab/android/client/BaseEncoder.java 59 | https://github.com/chromium/chromium/blob/0ddb38eda131f19995ec537bc67b62d35170e2ab/media/base/android/java/src/org/chromium/media/MediaCodecUtil.java 60 | 能参考的项目基本上都是推流中使用的。 61 | chromium中对硬编部分，做了CPU判断，从我的代码上线至今收集到的日志，应该是有点关系的。后续我也会跟进完善 62 | 63 | 64 | ## Usage 65 | 具体可以参照Demo，MainActivity中的调用 66 | 67 | * 最新的方案参考method4(view: View)方法 68 | 69 | **旧：** 70 | 1. 实现```ISourceProvider```接口 71 | 2. 指定输出路径 72 | 3. 设定参数 73 | 1. 可配置项很多，可以看类中没有private的成员变量 74 | ```kotlin 75 | // 比如视频的格式类型 acv h264, hevc h265，但要注意，很多手机还不能硬解硬编h265 76 | videoMimeType 77 | ``` 78 | 4. 开始录屏 79 | ```kotlin 80 | val outputFile = File(externalCacheDir, "record_${System.currentTimeMillis()}.mp4") 81 | val sourceProvider = object : ISourceProvider { 82 | override fun next(): Bitmap { 83 | return RecordViewUtil.getBitmapFromView(window, view, 800) 84 | } 85 | 86 | override fun onResult(isSuccessful: Boolean, result: String) { 87 | Log.w(TAG, "onResult() isSuccessful: $isSuccessful, result: $result") 88 | } 89 | } 90 | // 方案1：便捷方式 91 | mRecordEncoder.start(sourceProvider, outputFile, 1024_000, true) 92 | // 方案2: 先设定好参数，在业务处启动 93 | mRecordEncoder.setUp(sourceProvider, outputFile, 1024_000, true) 94 | mRecordEncoder.start() 95 | // 方案3: 无需读写权限，等结束回调返回路径 96 | mRecordEncoder.start( 97 | window, 98 | view, 99 | isRecordAudio = false 100 | ) { isSuccessful: Boolean, result: String -> 101 | Log.w(TAG, "onResult() isSuccessful: $isSuccessful, result: $result") 102 | } 103 | ``` 104 | 5. 要排查问题可以打开日志输出 105 | ```kotlin 106 | VRLogger.logLevel = Log.VERBOSE 或者 Log.DEBUG 级别 107 | ``` 108 | 109 | 110 | ## 优点： 111 | 1. 不需要权限，主要说得是录屏的那个敏感权限弹窗。如果需要录音，那录音权限还是需要的。 112 | 2. 解决隐私问题，常规录屏方案可能会录到用户的隐私信息，比如聊天记录、各类账号、短信验证码等。 113 | 3. 不会因为下拉状态栏等，需要录制的内容被遮盖。 114 | 4. 自定义源更灵活。 115 | 116 | ## 缺点： 117 | 1. 只能录制应用内的前台内容（录后台内容其实可以实现，自己控制下next的输入源就可以了，理论上扩展性很高）。 118 | 2. 不能录制SurfaceView的内容，原理问题，如果需要录摄像头或者Player需要使用TextureView。 119 | 120 | 121 | ## 难点 122 | 1. 帧率控制。(已解决) 123 | 2. 启动帧同步，目前采用视频帧启动后再输入音频。目前还是会丢启动时的部分帧，待解决 124 | 3. 不同机型的颜色格式适配，暂未完全解决。（大致解决，具体原因看5/20那条更新） 125 | 4. 视频输入源耗时问题，会导致实际帧率下降，大分辨率的情况下比较明显，如果异步采集合成，时间一长，积压的帧多了内存会爆炸，后续可能需要改算法方案来提高效率。 126 | 127 | 128 | ## To-Do List 129 | - [ ] 代码优化抽象，方便后续升级扩展（第一个版本写的比较急） 130 | - [ ] 上传到公共仓库 131 | - [x] Bitmap - Pixels 算法效率提升 132 | - [x] 机型适配 133 | - [x] 帧率提升 134 | - [x] 麦克风降噪 135 | - [ ] 合入其他音频源 136 |
