OMX.qcom encoder random crash

Question

The app is based on Grafika's camera capture activity (https://github.com/google/grafika/tree/master/src/com/android/grafika). The user taps on a button to record a video. A random crash is happening on Nexus 5x. Posted below are 2 logs of when it is working and when it is not. Please tell me what might be the cause of this crash and if you need me to post any part of the code.

Answer 1

I have been encountered a similar question, not sure if it is the same.

When it is working, it should come out with the fallowing log information.

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))

So the encoder could receive the status of buffer at initialization phase.

encoderStatus == MediaCodec.INFO_OUTPUT_FORMAT_CHANGED

In my program, the OnframeAvailable function and the render thread have been locked at the same time and no longer been able to notify each other at the start of recording initialization. Since the OnframeAvailable function has been stuck, the buffer could not be updated. As the result, the MeidaCodec never get the INFO_OUTPUT_FORMAT_CHANGED status.

Check if the frameAvailable() or frameAvailableSoon() is keeping update when recording start.
