我正在开发一个macOS应用程序，我不时会收到一个奇怪的错误。我使用AVPlayer流式传输实时视频。一切正常，但经过一段时间的流媒体突然，应用程序崩溃了以下错误：
libBacktraceRecording.dylib`__gcd_queue_item_enqueue_hook_block_invoke:
0x10019fe32 <+0>: pushq %rbp
0x10019fe33 <+1>: movq %rsp, %rbp

0x10019fe3a <+8>: movq 0x20(%rdi), %rcx

0x10019fe42 <+16>: sete %al
0x10019fe45 <+19>: popq %rbp
0x10019fe46 <+20>: retq
控制台日志中的消息如下所示：
