Crash (libUVCCamera) with EMI spike

[alex-breen-ampa]

This component is awesome, but we are having trouble with a severe app crash when there is an EMI/electrical spike on the USB line.

The crash appears to originate from low-level C/C++ (NDK) code and occurs in libUVCCamera. Possibly an issue with thread synchronization issue, improper cleanup, or memory corruption.

Crash Log Highlights:

• Signal: SIGABRT (abort)
• Library: libc (abort at +0x0950b0)
• Potential Issue Location:
• • pthread_join (libc +0x0fd974)
• • UVCPreview::stopPreview (libUVCCamera +0x012bb4)
• • UVCCamera::stopPreview (libUVCCamera +0x00ba60)

A fix or guidance on how to workaround it would be greatly appreciated.

Seems like crash in

react-native-uvc-camera/libuvccamera/src/main/jni/UVCCamera/UVCPreview.cpp

Line 361 in 18db77e

if (pthread_join(capture_thread, NULL) != EXIT_SUCCESS) {

or in

react-native-uvc-camera/libuvccamera/src/main/jni/UVCCamera/UVCPreview.cpp

Line 364 in 18db77e

if (pthread_join(preview_thread, NULL) != EXIT_SUCCESS) {

you can try to debug it, good luck and wish a PR 😜
