该应用程序基于Grafika的相机捕捉活动(https://github.com/google/grafika/tree/master/src/com/android/grafika).用户点击按钮以录制视频. Nexus 5x发生随机崩溃.下面发布的是它工作时和不工作时的2个日志.请告诉我这次崩溃的原因可能是什么,如果你需要我发布代码的任何部分.

解决方法:
我遇到过类似的问题,不确定它是否相同.
当它工作时,它应该与退出的日志信息一起出来.
D/ACodec: dataspace changed to 0x10c10000 (R:2(Limited), P:1(BT709_5), M:1(BT709_5), T:3(SMPTE170M)) (R:2(Limited), S:1(BT709), T:3(SMPTE_170M))
因此编码器可以在初始化阶段接收缓冲区的状态.
encoderStatus == MediaCodec.INFO_OUTPUT_FORMAT_CHANGED
在我的程序中,OnframeAvailable函数和渲染线程已同时被锁定,并且在记录初始化开始时不再能够相互通知.由于OnframeAvailable函数已被卡住,因此无法更新缓冲区.结果,MeidaCodec永远不会获得INFO_OUTPUT_FORMAT_CHANGED状态.
在录制开始时检查frameAvailable()或frameAvailableSoon()是否保持更新.
