那些遇到过的问题

为什么“queueInputBuffer”中的“MediaCodec CodecException”仅发生在 Android API 29 上？

mic*_*all 3 android video-encoding input-buffer mediamuxer android-mediacodec

基本信息

目标SDK版本28

目标：课程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，该代码在Pixel 2 API 28上运行良好，但在Pixel 2 API 29上运行不佳

源代码：我主要使用来自bigflake.com的示例代码。

错误信息（详细日志见下文）：

我尝试过的 由于 的日志信息有限，我尝试从 更改为MediaCodec$CodecException，但没有成功。MediaCodecInfo.CodecCapabilities.COLOR_FormatSurfaceMediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Flexible

日志将显示最后两个缓冲周期。我希望你能看到一些有价值的东西。

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

xxxxExtractor.readSampleData我修改了我的代码，仅在returns返回的大小之后标记提取器完成-1，这样您就知道发送到queueInputBuffer 的缓冲区是空的。

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