android - 为什么 "MediaCodec CodecException"中的 "queueInputBuffer"只发生在 Android API 29 上？

Question

基本信息

targetSdkVersion 28

目标:类(class)的目标是在发送到我的服务器之前调整视频大小。

问题:应用程序仅在 API 29 上崩溃，无论是使用真实设备还是使用 AVD。例如，代码在 Pixel 2 API 28 上运行良好，但在 Pixel 2 API 29

上运行良好

源代码:我主要使用 bigflake.com 中的示例代码.

错误信息(详细日志见下文):

E/AndroidRuntime: FATAL EXCEPTION: Thread-20
    Process: com.myapp.myapp, PID: 9189
    android.media.MediaCodec$CodecException: Error 0xfffffff3
        at android.media.MediaCodec.native_queueInputBuffer(Native Method)
        at android.media.MediaCodec.queueInputBuffer(MediaCodec.java:2450)

我的尝试由于 MediaCodec$CodecException 的日志信息有限，我尝试从 MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface 更改为 MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Flexible 没有成功.

日志会显示最近两个缓冲周期。我希望你会看到一些有值(value)的东西。

Answer 1

我认为正确的做法是在 xxxxExtractor.advance() 返回 false 后让它再循环一次。

我修改了我的代码，只在 xxxxExtractor.readSampleData 返回的大小返回 -1 之后标记提取器完成，这样你就知道你发送到 queueInputBuffer 的缓冲区是空。

所以:xxxxExtractorDone = !xxxxExtractor.advance(); ->xxxxExtractorDone = !xxxxExtractor.advance() && size == -1;
