android - OMX.qcom编码器随机崩溃

Question

该应用基于 Grafika 的相机捕捉 Activity (https://github.com/google/grafika/tree/master/src/com/android/grafika)。用户点击一个按钮来录制视频。 Nexus 5x 发生随机崩溃。下面发布了 2 个日志，说明它何时工作，何时不工作。请告诉我这次崩溃的可能原因是什么，以及您是否需要我发布代码的任何部分。

工作:

Answer 1

我也遇到过类似的问题，不知道是不是一样。

运行时，应该会出来休闲日志信息。

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函数和渲染线程已经被同时锁定，无法再在录制初始化开始时互相通知。由于OnframeAvailable函数一直卡住，无法更新buffer。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。
