Can someone guide me to debug this crash and resolve the issue? ————————————————————————————————— Crash sample got by a thirdparty framework: 0x00000001048cc000 Caused by:Applicationreceived signal 5 0 libsystem_malloc.dylib 0x000000019771a020 0x0000000197718000 + 8224 1 libdispatch.dylib 0x000000018ee88a1c 0x000000018ee87000 + 6684 2 libdispatch.dylib 0x000000018ee88a1c 0x000000018ee87000 + 6684 3 libdispatch.dylib 0x000000018ee90258 0x000000018ee87000 + 37464 4 CoreMedia 0x000000019439d704 0x00000001942cc000 + 857860 5 CoreMedia 0x00000001943a3bb4 0x00000001942cc000 + 883636 6 CoreMedia 0x00000001943a3688 0x00000001942cc000 + 882312 7 CoreMedia 0x00000001943a32f8 0x00000001942cc000 + 881400 8 MediaToolbox 0x0000000198736d0c 0x0000000198469000 + 2940172 9 libsystem_pthread.dylib 0x0000000211624d98 0x0000000211624000 + 3480 10 libsystem_platform.dylib 0x0000000211579d98 0x0000000211579000 + 3480 11 libsystem_platform.dylib 0x00000002115798d0 0x0000000211579000 + 2256 12 libsystem_pthread.dylib 0x0000000211628bfc 0x0000000211624000 + 19452 13 MediaToolbox 0x00000001987366dc 0x0000000198469000 + 2938588 14 AVFCore 0x0000000199078f98 0x0000000198fc1000 + 753560 15 AVFCore 0x000000019907825c 0x0000000198fc1000 + 750172 16 AVFCore 0x0000000199076de0 0x0000000198fc1000 + 744928 17 ICBCBankTest 0x0000000108ca5fc4 -[YTVideoRecorder startWith:withWidth:withHeight:withCodecSetting:withAudioSetting:] (in XXXApp) (YTVideoRecorder.mm:114) YTVideoRecorder.mm:114 should be the following code: [videoWriter startWriting]; [videoWriter startSessionAtSourceTime:kCMTimeZero]; And videoWriter is an instance of AVAssetWriter. Currently, memory exhaustion and storage space exhaustion can be ruled out. And AVAssetWriter is used in a single thread. Thanks!
